    In recent years, sophisticated technology has significantly increased the sensitivity and analytical power of genetic analyses so that very little starting material may now produce viable genetic profiles. This sensitivity however, has also increased the risk of detecting unknown genetic profiles assumed to be that of the perpetrator, yet originate from extraneous sources such as from crime scene workers. These contaminants may mislead investigations, keeping criminal cases active and unresolved for long spans of time. Voluntary submission of DNA samples from crime scene workers is fairly low, therefore we have created a promotional method for our staff elimination database that has resulted in a significant increase in voluntary samples since 2011. Our database enforces privacy safeguards and allows for optional anonymity to all staff members. We also offer information sessions at various police precincts to advise crime scene workers of the importance and success of our staff elimination database. This study, a pioneer in its field, has obtained 327 voluntary submissions from crime scene workers to date, of which 46 individual profiles (14%) have been matched to 58 criminal cases. By implementing our methods and respect for individual privacy, forensic laboratories everywhere may see similar growth and success in explaining unidentified genetic profiles in stagnate criminal cases.

    Forensic physicians provide both medical care and forensic consultations to detainees in police custody. There is a paucity of Australian data regarding characteristics of detainees and the type of work provided by forensic physicians in this setting. This retrospective audit of a clinical forensic service in Canberra, Australia will assist with service planning, future data collection and the training of forensic physicians.

    A series of tabletop and field exercises were designed and executed to test traditional forensic investigation procedures in a crime scene with radioactive material present. This allowed for specific training needs of forensic identification specialists to be identified and revised procedures to be drafted. Two scenarios were exercised, first as tabletop discussions with the Royal Canadian Mounted Police (RCMP), the Canadian Nuclear Safety Commission (CNSC), and DRDC Ottawa, and then as field exercises with the participation of the RCMP and Ottawa Police Services (OPS) forensic investigators. These exercises produced a number of lessons learned with regard to protocols for forensic investigators and led to the development of a one-page fact sheet on performing forensic identification tasks in a radiation environment.

    2017-12-21

    Human genetic variation is a major resource in forensics, but does not allow all forensically relevant questions to be answered. Some questions may instead be addressable via epigenomics, as the epigenome acts as an interphase between the fixed genome and the dynamic environment. We envision future forensic applications of DNA methylation analysis that will broaden DNA-based forensic intelligence. Together with genetic prediction of appearance and biogeographic ancestry, epigenomic lifestyle prediction is expected to increase the ability of police to find unknown perpetrators of crime who are not identifiable using current forensic DNA profiling.

  6. Seasonal Variations in Resistivity at a Police Forensic Site and the Effectiveness of Unconventional Array Types

    Geophysical studies involving the detection of buried organic material can be affected by the passage of time and environmental changes such as temperature and, in more importantly, water content in the ground. These effects can be of particular concern for police forensic investigations. This study involved conducting multiple resistivity surveys across 4 months to determine how time and environmental variations affected the detection of porcine carcasses buried four years previous at a provincial police training and research site. Our research also explored survey results of non-conventional grid and square arrays versus traditional linear arrays. The study site is located in Bolton, Ontario, and measures 16 m by 30 m. It contains 18 graves plus other buried objects. Studies were conducted approximately every other week. The resistivity lines used Wenner arrays of 24 m (0.5 m electrode spacing) and 48 m (1 m spacing) in length. Environmental data was obtained from Environment Canada and through simple observations. Preliminary findings indicated that time and environmental changes affected the detection of the porcine bodies by either being too dry and having too high a resistivity to survey effectively, or too wet and having the site flushed with water making the surrounding ground similar in resistivity to the bodies. Future research is needed to further explore how best to minimize environmental changes from resistivity results to enable reliable detection of buried organic material such as human remains In regard to array configurations, the square array in particular shows promise in that it can be set up and executed in less time than running several linear arrays over the same area. The application of such unconventional arrays to police forensic work may prove valuable if the area of interest is off-limits for resistivity surveys due to physical obstructions.

    Police investigations involve determining whether a crime has been committed, and if so what type of crime, who has committed it and whether there is the evidence to charge the perpetrators. Drawing on fieldwork in Delhi and Mumbai, this paper explores how police investigations unfolded in the specific context of women’s deaths by burning in India. In particular, it focuses on the use of discretion despite its denial by those exercising it. In India, there are distinctive statutes relating to women’s suspicious deaths, reflecting the widespread expectation that the bride’s family will pay a dowry to the groom’s family and the tensions to which this may on occasion give rise in the early years of a marriage. Often, there are conflicting claims influencing how the woman’s death is classified. These in turn affect police investigation. The nature and direction of police discretion in investigating women’s deaths by burning reflect in part the unique nature of the legislation and the particular sensitivities in relation to these types of death. They also highlight processes that are liable to be at work in any crime investigation. It was found that police officers exercised unacknowledged discretion at seven specific points in the investigative process, with potentially significant consequences for the achievement of just outcomes: first response, recording the victim’s ‘dying declaration’, inquest, registering of the ‘First Information Report’, collecting evidence, arrest and framing of the charges.

    Forensic odontology is the subdiscipline of dentistry which analyses dental evidence in the interest of justice. Oral pathology is the subdiscipline of dentistry that deals with the pathology affecting the oral and maxillofacial regions. This subdiscipline is utilized for identification through oral and maxillofacial pathologies with associated syndromes, enamel rod patterns, sex determination using exfoliative cytology, identification from occlusal morphology of teeth, and deoxyribonucleic acid profiling from teeth. This subdiscipline is also utilized for age estimation studies which include Gustafson's method, incremental lines of Retzius, perikymata, natal line formation in teeth, neonatal line, racemization of collagen in dentin, cemental incremental lines, thickness of the cementum, and translucency of dentin. Even though the expertise of an oral pathologist is not taken in forensic investigations, this paper aims to discuss the role of oral pathology in forensic investigation.

To govern IT organizations need to identify value of acquiring services of forensic firms to compete cyber criminals. Digital forensic firms follow different mechanisms to perform investigation. Time by time forensic firms are facilitated with different models for investigation containing phases for different purposes of the entire process. Along with forensic firms, enterprises also need to build a secure and supportive platform to make successful investigation process possible. We have underlined different elements of organizations in Pakistan; need to be addressed to provide support to forensic firms.

    To describe the epidemiological characteristics of ambulant psychiatric patients who were either brought to the police station or who came by themselves, but who were not kept in a cell, as a basis for the development of a reception protocol. Descriptive. The data from the medical records from 2000 kept by the forensic doctors employed by the district health services for the Southern South Holland region were inventoried. On request by the police, the forensic doctors examined 203 clients. The majority of these were middle-aged men who did have a place of residence. The reason for police involvement was bizarre or confused behaviour in public. Half of the patients had received or were receiving some form of psychiatric treatment from the mental health service. In approximately half of the cases the forensic doctor found a solution together with the police. In the other half of the cases the forensic doctor asked the crisis intervention team at the mental health service for an evaluation. Two thirds of these patients were hospitalised and one third was sent away. Because examination by both the forensic doctor and the mental health service psychiatrist and other procedures were lengthy (up to 6 hours), patients had to spend a long time in a holding cell at the police station that was not designed for stays of this length of time, and often lacked toilet facilities. The forensic doctor treated about half the clients without the need of assistance from the crisis intervention psychiatrist. The temporary accommodation for these confused clients was inadequate.

    Complaints management is an integral component of good clinical governance and an essential contributor to patient safety. Little is known about complaints against health-care professionals (HCPs) in police custodial settings and sexual assault referral centres. This study explored the frequency with which complaints are made against such HCPs working in England, Wales and Northern Ireland. It explored the nature of those complaints and the procedures by which they are investigated. Relevant information was requested from all police services in England, Wales and Northern Ireland; professional regulatory bodies; and the Independent Police Complaints Commission under the Freedom of Information Act (FOIA). Eighty-nine per cent of police services responded to the FOIA request. However, only a minority of these provided detailed information. Many police services cited the provision of health-care services by external providers as the reason for not holding information upon complaints. There was no evidence of any upward trend in the numbers of complaints over the study period. Delayed response to a request for attendance, incivility, medication issues and issues regarding the quality of reports and evidence were amongst the most common types of complaints described. A small number of responders provided copies of the disciplinary procedures used to manage complaints against HCPs. Significant heterogeneity exists in respect of complaints handling procedures across custodial and forensic medical/health-care services and sexual offence examiner services. An opportunity to identify learning for improvement is being missed as a result of the absence of standardised complaints handling procedures.

    Joseph, Isaac; Mathew, Deepu G; Sathyan, Pradeesh; Vargheese, Geetha

    2011-07-01

    Forensic entomology is the study of insects/arthropods in criminal investigation. Right from the early stages insects are attracted to the decomposing body and may lay eggs in it. By studying the insect population and the developing larval stages, forensic scientists can estimate the postmortem index, any change in position of the corpse as well as the cause of death. Forensic odontologists are called upon more frequently to collaborate in criminal investigations and hence should be aware of the possibilities that forensic entomology have to offer and use it as an adjunct to the conventional means of forensic investigation.

    Age estimation is useful in forensic investigations to aid in the process of identifying unknown victims as well as living individuals. In many countries age estimation is commonly used to assist immigration authorities in deciding whether refugees or illegal migrants have reached that designated age that separates a juvenile from an adult. This is particularly important for the protection of unaccompanied minors. Italy is a country of great appeal for immigration as people from other Mediterranean countries can easily reach Italian coasts. In Italy, as in other western world countries, unaccompanied asylum seekers deemed to be under 18 face a very different path through the immigration system. They cannot be deported and are sent through a juvenile system where they have access to education programmes and may be granted a residence permit. The Section of Legal Medicine of the University of Bari was approached by Judges and Immigration Police with the question to assess the age of unaccompanied asylum seekers who claim to be below 18 years of age. The contribution of forensic odontologists for age estimation was recognised and since November 2006 age estimation of asylum seekers in Bari (Italy) relies on clinical and dental examination together with skeletal maturation as seen on radiographs of the left hand and wrist, the pelvis for iliac crests and root development and mineralisation of third molars as seen on an orthopantomogram.

    Full Text Available A polygraph is an instrument that measures and records physiological changes inside the body. In the absence of a valid physical evidence, polygraphy may be a useful technique to verify truthfulness or detect deception. The present study was conducted to determine the truthfulness of a suspect in a murder case that was referred to PFSA for a polygraph examination. The stomach contents of the examinee and the hyoid bone of the vicvtim were submitted to the department of toxicology and forensic pathology at the PFSA, respectively. In the present study, integrated zone comparison technique (IZCT and forensic assessment interview technique (FAINT designed for specific and multi issue testing were used to examine the suspect. Computerized Academy for Scientific Investigative training (ASIT Algorithm and weighted scoring were applied in IZCT and FAINT scoring, respectively. The suspect of this murder case was brought to PFSA for polygraph examination. During the initial interview, the suspect denied any involvement in the said case. However, after complete polygraph examination, the suspect was proven to have been deceptive and later on confessed to police officials. The polygraph examination of the suspect proved him deceptive which was later confirmed by his confession. His stomach did not contain any toxic/ sedative material.

    2018-04-01

    Forensic science is increasingly used to help exonerate the innocent and establishing links between individuals and criminal activities. With increased reliance on scientific services provided by multi-disciplinary (police, medicine, law, forensic science), and multi-organisational in the private and government sectors (health, justice, legal, police) practitioners, the potential for miscommunication resulting unjust outcomes increases. The importance of identifying effective multi-organisational information sharing is to prevent the 'justice silo effect'; where practitioners from different organisations operate in isolation with minimal or no interaction. This paper presents the findings from the second part of the Interfaces Project, an Australia-wide study designed to assess the extent of the justice silos. We interviewed 121 police, forensic scientists, lawyers, judges, coroners, pathologists and forensic physicians. The first paper published in 2013 presented two key findings: first investigative meetings were rare in adult sexual assault cases; second many medical practitioners were semi-invisible in case decision-making with this low level of visibility being due to lawyers, forensic scientists or police not being aware of the role/expertise medical practitioners offer. These findings led to the development of a flowchart model for adult sexual assault that highlights the range of agencies and practitioners typically involved in sexual assault. The rationale for the flowchart is to produce a visual representation of a typical sexual assault investigative process highlighting where and who plays a role in order to minimise the risk of justice silos. This is the second paper in a series of two. Copyright © 2018 Elsevier B.V. All rights reserved.

    2009-04-01

    Patients suffer preventable harm from their medical treatment. The traditional approaches to investigating medical treatment related deaths are the 'hospital mortality audit' and legal or coroners investigation. The aim is to describe how the patient safety movement in the late 1990s is changing traditional approaches to the investigation. The prevention of medical treatment related death involves an investigation as one of five major stages. These are Stage I Preparedness; Stage II Recognition and reporting; Stage III Investigation and analysis; Stage IV Findings and recommendations; and Stage V Response. The influence of the patient safety approach is considered at each stage with a particular focus on Stage I. It is at this stage that the concepts of clinical governance, culture and systems of care have a major influence on the nature of an investigation. The genesis of the modern forensic investigation into medical treatment related deaths in Victoria, Australia is described. The formation of the Clinical Liaison Service incorporates concepts from the patient safety approach with clinical staff to transform the traditional Coroner's investigation. Benefits of a modern forensic investigation include improving appropriateness of cases proceeding to investigation and a focus on prevention. Achieving a reduction in medical treatment related death requires substantial shifts towards an approach consistent with the patient safety.

  8. Cyber Forensics Ontology for Cyber Criminal Investigation

    Science.gov (United States)

    Park, Heum; Cho, Sunho; Kwon, Hyuk-Chul

    We developed Cyber Forensics Ontology for the criminal investigation in cyber space. Cyber crime is classified into cyber terror and general cyber crime, and those two classes are connected with each other. The investigation of cyber terror requires high technology, system environment and experts, and general cyber crime is connected with general crime by evidence from digital data and cyber space. Accordingly, it is difficult to determine relational crime types and collect evidence. Therefore, we considered the classifications of cyber crime, the collection of evidence in cyber space and the application of laws to cyber crime. In order to efficiently investigate cyber crime, it is necessary to integrate those concepts for each cyber crime-case. Thus, we constructed a cyber forensics domain ontology for criminal investigation in cyber space, according to the categories of cyber crime, laws, evidence and information of criminals. This ontology can be used in the process of investigating of cyber crime-cases, and for data mining of cyber crime; classification, clustering, association and detection of crime types, crime cases, evidences and criminals.

    2017-10-01

    Forensic investigation on the crime scene is an activity that requires not only knowledge about the ways of searching for evidence, collecting and processing them. In some cases the area of operation might not be properly secured and poses threat to human health or life. Some devices or materials may be left intentionally or not to injure potential investigators. Besides conventional explosives, threats can be in form of CBRN materials, which have not only immediate effect on the exposed personnel, but can contaminate further people, when being transferred for example on clothes or unsecured equipment. In this case a risk evaluation should be performed, that can lead to conclusions that it is too dangerous for investigators to work. In that kind of situation remote devices, which are able to examine the crime scene and secure samples, can be used. In the course of R&D activities PIAP developed a system, which is based on small UGV capable of carrying out inspection of suspicious places and securing evidence, when needed. The system consists of remotely controlled mobile robot, its control console and a set of various inspection and support tools, that enable detection of CBRN threats as well as revelation, documentation and securing of the evidence. This paper will present main features of the system, like mission adjustment possibilities and communication aspects, and also examples of the forensic accessories.

    2017-07-01

    We explore the impact of information from ballistics imaging hit reports on the investigation into violent crimes. Ballistics imaging hits link two crimes involving the same firearm by forensically matching tool marks on the fired bullets or cartridge cases. Interview data collected from detectives who received a hit report were used to explore the relationship between the presence of a hit report and outcomes in 65 gun-related violent crime investigations in nine U.S. police agencies. Findings indicate hit reports rarely contribute to identification, arrest, charging, or sentencing of suspects, because of delays in producing hit reports. On average, hit reports were completed 181.4 days after the focal crime. This delay forces investigations to proceed without the benefit of information from ballistics analysis. Additionally, hit reports rarely contained detailed information that was immediately useful to investigators. Instead, hit reports required additional research by the investigator to unlock useful information. © 2017 American Academy of Forensic Sciences.

  13. Forensic DNA Phenotyping: Predicting human appearance from crime scene material for investigative purposes.

    Science.gov (United States)

    Kayser, Manfred

    2015-09-01

    Forensic DNA Phenotyping refers to the prediction of appearance traits of unknown sample donors, or unknown deceased (missing) persons, directly from biological materials found at the scene. "Biological witness" outcomes of Forensic DNA Phenotyping can provide investigative leads to trace unknown persons, who are unidentifiable with current comparative DNA profiling. This intelligence application of DNA marks a substantially different forensic use of genetic material rather than that of current DNA profiling presented in the courtroom. Currently, group-specific pigmentation traits are already predictable from DNA with reasonably high accuracies, while several other externally visible characteristics are under genetic investigation. Until individual-specific appearance becomes accurately predictable from DNA, conventional DNA profiling needs to be performed subsequent to appearance DNA prediction. Notably, and where Forensic DNA Phenotyping shows great promise, this is on a (much) smaller group of potential suspects, who match the appearance characteristics DNA-predicted from the crime scene stain or from the deceased person's remains. Provided sufficient funding being made available, future research to better understand the genetic basis of human appearance will expectedly lead to a substantially more detailed description of an unknown person's appearance from DNA, delivering increased value for police investigations in criminal and missing person cases involving unknowns.

    2005-09-01

    Forensic archaeology is an extremely powerful investigative discipline and, in combination with forensic anthropology, can provide a wealth of evidentiary information to police investigators and the forensic community. The re-emergence of forensic archaeology and anthropology within Australia relies on its diversification and cooperation with established forensic medical organizations, law enforcement forensic service divisions, and national forensic boards. This presents a unique opportunity to develop a new multidisciplinary approach to forensic archaeology/anthropology within Australia as we hold a unique set of environmental, social, and cultural conditions that diverge from overseas models and require different methodological approaches. In the current world political climate, more forensic techniques are being applied at scenes of mass disasters, genocide, and terrorism. This provides Australian forensic archaeology/anthropology with a unique opportunity to develop multidisciplinary models with contributions from psychological profiling, ballistics, sociopolitics, cultural anthropology, mortuary technicians, post-blast analysis, fire analysis, and other disciplines from the world of forensic science.

    In daily police practice, forensic investigation of criminal cases is mainly based on manual work and the experience of individual forensic experts, using basic storage and data processing technologies. However, an individual criminal case does not only consist of the actual offence, but also of a variety of different aspects involved. For example, in order to solve a financial criminal case, an investigator has to find interrelations between different case entities as well as to other cases. The required information about these different entities is often stored in various databases and mostly requires to be manually requested and processed by forensic investigators. We propose the application of semantic technologies to the domain of forensic investigations at the example of financial crimes. Such combination allows for modelling specific case entities and their interrelations within and between cases. As a result, an explorative search of connections between case entities in the scope of an investigation as well as an automated derivation of conclusions from an established fact base is enabled. The proposed model is presented in the form of a crime field ontology, based on different types of knowledge obtained from three individual sources: open source intelligence, forensic investigators and captive interviews of detained criminals. The modelled crime field ontology is illustrated at two examples using the well known crime type of explosive attack on ATM and the potentially upcoming crime type data theft by NFC crowd skimming. Of these criminal modi operandi, anonymized fictional are modelled, visualized and exploratively searched. Modelled case entities include modi operandi, events, actors, resources, exploited weaknesses as well as flows of money, data and know how. The potential exploration of interrelations between the different case entities of such examples is illustrated in the scope of a fictitious investigation, highlighting the potential of the

    Research and Development ('R&D') in forensic science currently focuses on innovative technologies improving the efficiency of existing forensic processes, from the detection of marks and traces at the scene, to their presentation in Court. R&D approached from this perspective provides no response to doubts raised by recent criminological studies, which question the effective contribution of forensic science to crime reduction, and to policing in general. Traces (i.e. forensic case data), as remnants of criminal activity are collected and used in various forms of crime monitoring and investigation. The aforementioned doubts therefore need to be addressed by expressing how information is conveyed by traces in these processes. Modelling from this standpoint expands the scope of forensic science and provides new R&D opportunities. Twelve propositions for R&D are stated in order to pave the way.

    Forensic science is a wide field comprising of several subspecialties and uses methods derived from natural sciences for finding criminals and other evidence valid in a legal court. A relatively new area; Nano-forensics brings a new era of investigation in forensic science in which instantaneous results can be produced that determine various agents such as explosive gasses, biological agents and residues in different crime scenes and terrorist activity investigations. This can be achieved by applying Nanotechnology and its associated characterization techniques in forensic sciences. Several characterization techniques exist in Nanotechnology and nano-analysis is one such technique that is used in forensic science which includes Electron microscopes (EM) like Transmission (TEM) and Scanning (SEM), Raman microscopy (Micro -Raman) and Scanning Probe Microscopes (SPMs) like Atomic Force Microscope (AFM). Atomic force microscopy enables surface characterization of different materials by examining their morphology and mechanical properties. Materials that are immeasurable such as hair, body fluids, textile fibers, documents, polymers, pressure sensitive adhesives (PSAs), etc. are often encountered during forensic investigations. This review article will mainly focus on the use of AFM in the examination of different evidence such as blood stains, forged documents, human hair samples, ammunitions, explosives, and other such applications in the field of Forensic Science.

    2012-03-01

    Full Text Available The numerous advantages offered by cloud computing has fuelled its growth and has made it one of the most significant of current computing trends. The same advantages have created complex issues for those conducting digital forensic investigations. Digital forensic investigators rely on the ACPO guidelines when conducting an investigation, however the guidelines make no reference to some of the issues presented by cloud investigations.This study investigates the impact of cloud computing on ACPO’s core principles and asks whether there is a need for the principles and guidelines to be reviewed to address the issues presented by cloud computing. Empirical research is conducted and data collected from key experts in the field of digital forensics.This research presents several key findings: there is a very real concern for how cloud computing will affect digital forensic investigations; the ACPO principles cannot easily be applied in all cloud investigations but are generally sufficient for cloud computing forensic investigations. However the advent of cloud computing is a significant development in technology and may in the near future warrant a review of the guidelines in particular to incorporate the involvement of third parties in cloud investigations.

    Nowadays, web applications are popular targets for security attackers. Using specific security mechanisms, we can prevent or detect a security attack on a web application, but we cannot find out the criminal who has carried out the security attack. Being unable to trace back an attack, encourages hackers to launch new attacks on the same system. Web application forensics aims to trace back and attribute a web application security attack to its originator. This may significantly reduce the sec...

    Full Text Available Disaster forensic investigation analyses the unfolding of a disaster and attempts to identify its multiple causes of damage which can lead to (i improved disaster prevention and management from lessons learnt, and (ii more effective mitigation measures in the aftermath of a disaster. The way in which damage data are collected after a flood event as well as the types of collected data influences their usability within forensic investigations. In order to explore whether or not existing data can be used for disaster forensic analysis, the European Project IDEA (Improving Damage assessments to Enhance cost-benefit Analyses is investigating existing gaps in damage information so as to identify possible paths towards improving data quality. This paper focuses in detail on a forensic analysis of the interlinked damage to economic activities and infrastructure in the Severn floods of 2007 in the UK. Besides investigating the usability of existing data, this research investigated: (i the relative weight of direct and indirect costs to business and infrastructure companies; (ii to what extent damage to infrastructure has impacted on indirect damage to businesses. Finally recommendations for improving the data for use in forensic investigation are offered.

    A 63-year-old man was found in the street after overrun by a car. Postmortem CT revealed multiple bone fractures, but surprisingly all without any relevant hemorrhage which would have been expected under such circumstances. A round radiopaque formation was found in the duodenum, which was reminiscent of ingested tablets. The toxicological analysis revealed high concentrations of zopiclone and alcohol. By combining radiologic and forensic results, zopiclone and alcohol intoxication were concluded as the cause of death, followed by a postmortem overrun accident.

    2016-01-01

    DNA methylation is emerging as an attractive marker providing investigative leads to solve crimes in forensic genetics. The identification of body fluids that utilizes tissue-specific DNA methylation can contribute to solving crimes by predicting activity related to the evidence material. The age estimation based on DNA methylation is expected to reduce the number of potential suspects, when the DNA profile from the evidence does not match with any known person, including those stored in the forensic database. Moreover, the variation in DNA implicates environmental exposure, such as cigarette smoking and alcohol consumption, thereby suggesting the possibility to be used as a marker for predicting the lifestyle of potential suspect. In this review, we describe recent advances in our understanding of DNA methylation variations and the utility of DNA methylation as a forensic marker for advanced investigative leads from evidence materials.

    Forensic investigations are primarily meant to obtain objective answers that can be used for criminal prosecution. Accident analyses are usually performed to learn from incidents and to prevent similar events from occurring in the future. Although the primary goal may be different, the steps in which information is gathered, interpreted and weighed are similar in both types of investigations, implying that forensic techniques can be of use in accident investigations as well. The use in accident investigations usually means that more information can be obtained from the available information than when used in criminal investigations, since the latter require a higher evidence level. In this paper, we demonstrate the applicability of forensic techniques for accident investigations by presenting a number of cases from one specific field of expertise: image analysis. With the rapid spread of digital devices and new media, a wealth of image material and other digital information has become available for accident investigators. We show that much information can be distilled from footage by using forensic image analysis techniques. These applications show that image analysis provides information that is crucial for obtaining the sequence of events and the two- and three-dimensional geometry of an accident. Since accident investigation focuses primarily on learning from accidents and prevention of future accidents, and less on the blame that is crucial for criminal investigations, the field of application of these forensic tools may be broader than would be the case in purely legal sense. This is an important notion for future accident investigations. Copyright © 2017 Elsevier B.V. All rights reserved.

  7. A Comprehensive and Harmonized Digital Forensic Investigation Process Model.

    Valjarevic, Aleksandar; Venter, Hein S

    2015-11-01

    Performing a digital forensic investigation (DFI) requires a standardized and formalized process. There is currently neither an international standard nor does a global, harmonized DFI process (DFIP) exist. The authors studied existing state-of-the-art DFIP models and concluded that there are significant disparities pertaining to the number of processes, the scope, the hierarchical levels, and concepts applied. This paper proposes a comprehensive model that harmonizes existing models. An effort was made to incorporate all types of processes proposed by the existing models, including those aimed at achieving digital forensic readiness. The authors introduce a novel class of processes called concurrent processes. This is a novel contribution that should, together with the rest of the model, enable more efficient and effective DFI, while ensuring admissibility of digital evidence. Ultimately, the proposed model is intended to be used for different types of DFI and should lead to standardization. © 2015 American Academy of Forensic Sciences.

    IoT-Forensics is a novel paradigm for the acquisition of electronic evidence whose operation is conditioned by the peculiarities of the Internet of Things (IoT) context. As a branch of computer forensics, this discipline respects the most basic forensic principles of preservation, traceability, documentation, and authorization. The digital witness approach also promotes such principles in the context of the IoT while allowing personal devices to cooperate in digital investigations by voluntarily providing electronic evidence to the authorities. However, this solution is highly dependent on the willingness of citizens to collaborate and they may be reluctant to do so if the sensitive information within their personal devices is not sufficiently protected when shared with the investigators. In this paper, we provide the digital witness approach with a methodology that enables citizens to share their data with some privacy guarantees. We apply the PRoFIT methodology, originally defined for IoT-Forensics environments, to the digital witness approach in order to unleash its full potential. Finally, we show the feasibility of a PRoFIT-compliant digital witness with two use cases.

    2011-06-01

    Full Text Available Electronic Mail (E-Mail, which is one of the most widely used applications of Internet, has become a global communication infrastructure service.  However, security loopholes in it enable cybercriminals to misuse it by forging its headers or by sending it anonymously for illegitimate purposes, leading to e-mail forgeries. E-mail messages include transit handling envelope and trace information in the form of structured fields which are not stripped after messages are delivered, leaving a detailed record of e-mail transactions.  A detailed header analysis can be used to map the networks traversed by messages, including information on the messaging software and patching policies of clients and gateways, etc. Cyber forensic e-mail analysis is employed to collect credible evidence to bring criminals to justice. This paper projects the need for e-mail forensic investigation and lists various methods and tools used for its realization. A detailed header analysis of a multiple tactic spoofed e-mail message is carried out in this paper. It also discusses various possibilities for detection of spoofed headers and identification of its originator. Further, difficulties that may be faced by investigators during forensic investigation of an e-mail message have been discussed along with their possible solutions.

  13. Ecotoxicological evaluation of sediments applied to environmental forensic investigation

    Full Text Available Abstract The present study aimed to evaluate the potential for using toxicity assays with sediment samples for the detection of water pollution caused by the discharge of tannery effluents into water bodies and its application to environmental forensic investigation. The study included ecotoxicological evaluation of sediments, survey of benthic organisms in the field, as well as chromium, cadmium and lead dosage which provided data for a sediment quality triad evaluation. The sediment samples showed acute and chronic toxicity to the bioindicators, low biodiversity of benthic macrofauna and high chromium concentration, reaching up to 4365 mg.Kg–1. A close relationship was observed between the separate results of ecotoxicological sediment evaluation and the sediment quality triad. The sediment ecotoxicological assessment proved to be applicable to tracking sources of contamination related to tanneries and similar activities in environmental forensics.

    According to Greek legislation the medico-legal investigation of deaths occurring in prisons is mandatory. Furthermore, in cases of suicide or of suspected suicide the contribution of medico-legal investigation is of grave importance. The current paper addresses the medico-legal investigation of suicide cases in Greek correctional facilities and aims to describe the current situation. Our study consists of the meticulous research in the data records of major Greek correctional facilities, for the time period 1999-2010. Official permission was obtained by the Hellenic Ministry of Justice, which provided us the access to the records. Data was also collected from the Piraeus Forensic Service, from the Department of Pathological Anatomy of the University of Athens and finally from our own records. Measures were taken to respect the anonymity of the cases. Data was collected for the social, penal, medical history as well as for the medico-legal investigation. It appears that 85.7% of suicide cases were transferred to the Prisoner's Hospital (p < 0.0001), the forensic pathologist who conducted the PME did not perform scene investigation in none of the 70 suicide cases. In a total of 70 cases, histopathological examination, was requested only in 30 cases (42.9%). Hanging was the preferred method for those who committed suicide, followed by the poisoning due to psychoactive substances. Understanding the mistakes made during the forensic investigation of suicide cases inside correctional facilities is necessary, in order to prevent them from occurring again in the future, by implementing appropriate new policies and guidelines.

  16. The interface between the phonetic scientist and forensic investigations

    2003-10-01

    Many scientists find the interface with criminal/civil investigations and the resulting litigation quite challenging. The great variety found among such cases and their (sometimes) shockingly grim aspects, can be most daunting. Moreover, the aid these scientists can expect when attempting to learn their responsibilities (while good) tends to focus only on the roles they will play in the courts. The reality is that they also must serve in a second domain that of investigator/consultant to law enforcement personnel and attorneys. Since training, structure and guidelines are lacking in this area, the relevant problems must be addressed (and solved) directly by the scientist. To do so, he/she must (1) learn about the parallels between laboratory investigations and forensic investigations and organize links, (2) compensate for the differences between them, (3) organize scientific personnel for collaborations in support of the needs of the practitioners, (4) adapt laboratory procedures for forensic application, (5) establish criteria for these applications and (6) develop and articulate what can and cannot be expected of these procedures. Brief case reviews will be presented to illustrate each of these issues.

  18. Predictors of patrol officer interest in cybercrime training and investigation in selected United States police departments.

    Science.gov (United States)

    Holt, Thomas J; Bossler, Adam M

    2012-09-01

    Cybercrime has created substantial challenges for law enforcement, particularly at the local level. Most scholars and police administrators believe that patrol officers need to become more effective first responders to cybercrime calls. The evidence illustrates, however, that many patrol officers are neither adequately prepared nor strongly interested in taking an active role in addressing cybercrime at the local level. This study, therefore, examined the factors that predicted patrol officer interest in cybercrime training and investigations in two southeastern U.S. cities. The study specifically examined the relationship between demographics, cybercrime exposure, computer training, computer proficiency, Internet and cybercrime perceptions, and views on policing cybercrime with officer interest in cybercrime investigation training and conducting cybercrime investigations in the future. Officer views on policing cybercrime, particularly whether they valued cybercrime investigations and believed that cybercrime would dramatically change policing, along with their computer skills, were the strongest predictors of interest in cybercrime efforts. Officers who had received previous computer training were less interested in additional training and conducting investigations. These findings support the argument that more command and departmental meetings focusing on the value of investigating these types of crime need to be held in order to increase officer interest.

    The forensic evaluation of trauma in occupational injuries and fatalities can provide the benefit of a more thorough analysis of incident causation. Forensic nursing science applied during workplace investigations can assist investigators to determine otherwise unknown crucial aspects of the incident circumstances that are important to event reconstruction, the enforcement of occupational health and safety requirements, and the direction of workplace prevention initiatives. Currently, a medical and forensic medical knowledge gap exists in the subject-matter expertise associated with occupational accident investigations. This gap can be bridged with the integration of forensic nursing in the investigation of workplace fatalities and serious injuries.

    This is the first overview to be published of the whole field of forensic mycology. It is based on all available information located in the literature, together with 13 examples from recent casework. Background information on fungi is given, and this is followed by an outline of the value, and potentially wide application, of mycology in criminal investigation. Applications include roles in: providing trace evidence; estimating time since death (post-mortem interval); ascertaining time of deposition; investigating cause of death, hallucinations, or poisonings; locating buried corpses; and biological warfare. Previous work has been critically evaluated, with particular attention to its evidential value, and suitability for presentation in a court of law. The situations where mycology might assist an investigation are summarised, and issues relating to the further development of the subject are presented.

    2011-01-01

    Since the fall of the Iron Curtain illicit trafficking of nuclear and radioactive material has become an issue of concern both on the political and the scientific level. Seized material may be analysed in order to obtain clues on its origin and intended use and to prevent diversion of material from the same source in the future. Nuclear materials (uranium or plutonium) are of particular worry due to the nuclear proliferation risk associated with the material. Nuclear forensic investigations are aimed at the fact that nuclear material carries (inherent) information on its history, including on its origin and the processes applied for its production. Important conclusions can be drawn from decay products, activation products and fission products. Chemical impurities and the isotopic composition of certain major and minor constituents may provide additional information. Comparison of the measured results with nuclear material databases may yield evidence on the production site. The paper will describe the methodologies developed for addressing the above issues, focussing on radiochemical methods. Examples of nuclear forensic casework will illustrate the experience gathered in these areas. (orig.)

    Despite reports documenting adverse effects of stress on police marriages, few empirical studies focus on actual emotional behaviors of officers and spouses. In this preliminary investigation, 17 male police officers and their nonpolice wives completed daily stress diaries for 1 week and then participated in a laboratory-based discussion about their respective days. Conversations were video-recorded and coded for specific emotional behaviors reflecting hostility and affection, which are strong predictors of marital outcomes. We examined associations between officers’ job stress (per diaries and the Police Stress Survey) and couples’ emotional behavior (mean levels and behavioral synchrony) using a dyadic repeated measures design capitalizing on the large number of observations available for each couple (1020 observations). When officers reported more job stress, they showed less hostility, less synchrony with their wives’ hostility, and more synchrony with their wives’ affection; their wives showed greater synchrony with officers’ hostility and less synchrony with officers’ affection. Therefore, for officers, greater job stress was associated with less behavioral negativity, potentially less attunement to wives’ negativity, but potentially greater attunement to wives’ affection—perhaps a compensatory strategy or attempt to buffer their marriage from stress. These attempts may be less effective, however, if, as our synchrony findings may suggest, wives are focusing on officers’ hostility rather than affection. Although it will be important to replicate these results given the small sample, our findings reveal that patterns of behavioral synchrony may be a key means to better understand how job stress exacts a toll on police marriages.

In February 2013 the Australian Crime Commission released a report that linked several professional sporting codes, professional athletes with links to organised crime, performance enhancing drugs and illicit substances. Following this report the Australian Football League (AFL) partnered the Australian national antidoping organisation to investigate peptide use in Australian football. This review compared the model proposed by Marclay, a hypothetical model for anti-doping investigations that proposed a forensic intelligence and analysis approach, to use the forensic capabilities of the AFL investigation to test the model's relevance to an actual case. The investigation uncovered the use of peptides used to enhance athlete performance. The AFL investigation found a high risk of doping where athlete support staff existed in teams with weak corporate governance controls. A further finding included the need for the investigation to provide a timely response in professional team sports that were sensitive to the competition timing. In the case of the AFL the team was sanctioned prior to the finals as an interim outcome for allowing the risk of use of performance-enhancing substances. Doping violation charges are still being considered. Antidoping strategies should include the investigation of corporate officers in team doping circumstances, the mandatory recording of all athlete substance use during competition and training phases, the wider sharing of forensic intelligence with non-sporting bodies particularly law enforcement and collaboration between antidoping and sporting organisations in doping investigations

    Ludwig, Anika; Fraser, Jim

    2014-01-01

    New scientific, technological and legal developments, particularly the introduction of national databases for DNA and fingerprints, have led to increased use of forensic science in the investigation of crime. There is an assumption, and in some instances specific assertions, that such developments bring improvements either in broad criminal justice terms or more narrowly in terms of economic or practical efficiencies. The underlying presumption is that the new technological opportunities will be understood and effectively implemented. This research investigates whether such increases in activity have also been accompanied by improvements in the effective use of forensic science. A systematic review of thirty-six reports published (predominantly in England and Wales) since the 1980s, which have considered the use of forensic science in the investigation of volume crimes, was carried out. These reports have identified a number of recurrent themes that influenced how effectively forensic science was used in investigations. The themes identified included forensic knowledge and training of investigators, communication and information exchange between specialists and investigators, timeliness of forensic results, interagency relationships and deployment of crime scene examiner resources. The research findings suggest that these factors continue to hinder the effective use of forensic science despite technological advances and this paper considers their potential causes. © 2013.

  8. Tiger hair morphology and its variations for wildlife forensic investigation

    2013-11-01

    Full Text Available Tiger population has dramatically decreased due to illegal consumption and commercialisation of their body parts. Frequently, hair samples are the only evidence found in the crime scene. Thus, they play an important role in species identification for wildlife forensic investigation. In this study, we provide the first in-depth report on a variety of qualitative and quantitative characteristics of tiger guard hairs (24 hairs per individual from four individuals. The proposed method could reduce subjectivity of expert opinions on species identification based on hair morphology. Variations in 23 hair morphological characteristics were quantified at three levels: hair section, body region, and intra-species. The results indicate statistically significant variations in most morphological characteristics in all levels. Intra-species variations of four variables, namely hair length, hair index, scale separation and scale pattern, were low. Therefore, identification of tiger hairs using these multiple features in combination with other characteristics with high inter-species variations (e.g. medulla type should bring about objective and accurate tiger hair identification. The method used should serve as a guideline and be further applied to other species to establish a wildlife hair morphology database. Statistical models could then be constructed to distinguish species and provide evidential values in terms of likelihood ratios.

    Miller Coyle, Heather; Lee, Cheng-Lung; Lin, Wen-Yu; Lee, Henry C; Palmbach, Timothy M

    2005-08-01

    Forensic botany is still an under-utilized resource in forensic casework, although it has been used on occasion. It is an area of specialty science that could include traditional botanical classification of species, DNA, or materials evidence (trace and transfer evidence), crime mapping or geo-sourcing, all dependent on the specific case application under consideration. Critical to the evaluation of plant evidence is careful collection, documentation, and preservation for later scientific analysis. This article reviews proper procedures and recent cases where botanical evidence played a role in establishing either manner or time of death. Plant evidence can be useful for determining if a death was due to an accident, suicide, or homicide, or what time of year burial may have taken place. In addition, plant evidence can be used to determine if a crime scene is a primary or secondary scene and to locate missing bodies.

  11. Forensic geoscience: applications of geology, geomorphology and geophysics to criminal investigations

    Ruffell, Alastair; McKinley, Jennifer

    2005-03-01

    One hundred years ago Georg Popp became the first scientist to present in court a case where the geological makeup of soils was used to secure a criminal conviction. Subsequently there have been significant advances in the theory and practice of forensic geoscience: many of them subsequent to the seminal publication of "Forensic Geology" by Murray and Tedrow [Murray, R., Tedrow, J.C.F. 1975 (republished 1986). Forensic Geology: Earth Sciences and Criminal Investigation. Rutgers University Press, New York, 240 pp.]. Our review places historical development in the modern context of how the allied disciplines of geology (mineralogy, sedimentology, microscopy), geophysics, soil science, microbiology, anthropology and geomorphology have been used as tool to aid forensic (domestic, serious, terrorist and international) crime investigations. The latter half of this paper uses the concept of scales of investigation, from large-scale landforms through to microscopic particles as a method of categorising the large number of geoscience applications to criminal investigation. Forensic geoscience has traditionally used established non-forensic techniques: 100 years after Popp's seminal work, research into forensic geoscience is beginning to lead, as opposed to follow other scientific disciplines.

    The most widely accepted model of juror decision making acknowledges the importance of both the case-specific information presented in the courtroom, as well as the prior general knowledge and beliefs held by each juror. The studies presented in this paper investigated whether mock jurors could differentiate between evidence of varying strengths in the absence of case information and then followed on to determine the influence that case context (and therefore the story model) has on judgments made about the strength of forensic DNA evidence. The results illustrated that mock jurors correctly identified various strengths of evidence when it was not presented with case information; however, the perceived strength of evidence was significantly inflated when presented in the context of a criminal case, particularly when the evidence was of a weak or ambiguous standard. These findings are discussed in relation to the story model, and the potential implications for real juries. © 2011 American Academy of Forensic Sciences.

    The use of non-human DNA typing in forensic science investigations, and specifically that from animal DNA, is ever increasing. The term animal DNA in this document refers to animal species encountered in a forensic science examination but does not include human DNA. Non-human DNA may either be: the trade and possession of a species, or products derived from a species, which is contrary to legislation; as evidence where the crime is against a person or property; instances of animal cruelty; or where the animal is the offender. The first instance is addressed by determining the species present, and the other scenarios can often be addressed by assigning a DNA sample to a particular individual organism. Currently there is little standardization of methodologies used in the forensic analysis of animal DNA or in reporting styles. The recommendations in this document relate specifically to animal DNA that is integral to a forensic science investigation and are not relevant to the breeding of animals for commercial purposes. This DNA commission was formed out of discussions at the International Society for Forensic Genetics 23rd Congress in Buenos Aires to outline recommendations on the use of non-human DNA in a forensic science investigation. Due to the scope of non-human DNA typing that is possible, the remit of this commission is confined to animal DNA typing only. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    This study investigated the current status of infection management for forensic science investigators in South Korea. This study included 104 forensic science investigators, of which 97.1% were exposed to the blood or body fluids of corpses during handling. Of these investigators, 98% claimed they wore gloves, and 12.9% used double-layered gloves. A total of 70.6% of the participants with relevant work experience wore masks to reduce infection risk; 43% wore gowns and goggles when at risk of contracting an infection. Furthermore, 59.8% of the investigators with pertinent work experience sought appropriate first aid and treatment when they experienced contaminated skin cuts or stab wounds. Working conditions and other problems should be analyzed consistently with the cooperation of employees, occupational health practitioners, and relevant organizations to prevent work-associated infections among forensic science investigators. © 2015 The Author(s).

    The aim of this study was to understand factors that influence post-traumatic stress (PTS) in Korean forensic science investigators. A total of 111 forensic science investigators were recruited in Korea. PTS was measured using the tool modified by Choi (2001) from the original developed by Foa, Riggs, Dancu, and Rothbaum (1993) based on DSM-IV. Factors influencing PTS included demographic and job-related characteristics, emotional intelligence, and death anxiety. PTS scores were positively correlated with personality type, fatigue from work, and death anxiety. PTS scores were negatively correlated with length of career as a forensic science investigator and emotional intelligence. The factors that had the greatest influence on PTS were death anxiety, years spent as a forensic science investigator, personality type, emotional intelligence, fatigue, and homicide experience. The explanatory power of these six factors was 44.0%. Therefore, it is necessary to regularly evaluate the mental health of those who are vulnerable to PTS. Based on these results, various interventions could be implemented for promoting overall health of the forensic science investigators. Copyright © 2013. Published by Elsevier B.V.

    Full Text Available This study investigated the English language needs, motivations and attitudes of a random sample of 223 police cadets studying at King Fahd Security College in Saudi Arabia. The analysis of the questionnaire results showed that only cadets with degrees in humanities received English instructions. The cadets selected speaking and listening as the most important skills and studying English for security purposes. As regards their motivations, the significant correlation between almost all the instrumental and integrative variables provided evidence to the integration of the two types of motivations which substantiates the importance of both types in English learning.  Statements describing negative attitudes toward the English culture did not statistically correlate with the other statements that constitute the cadets’ positive attitudes toward English learning, which confirmed their positive attitudes toward both English learning and its culture. The significant correlations between the cadets’ English perceived needs and their instrumental motivations supported the argument that ESP learners study English for utilitarian purposes.

  5. Geoethics and Forensic Geology

    2017-04-01

    The International Union of Geological Sciences (IUGS), Initiative on Forensic Geology (IFG) was set up in 2011 to promote and develop the applications of geology to policing and law enforcement throughout the world. This includes the provision of crime scene examinations, searches to locate graves or items of interest that have been buried beneath the ground surface as part of a criminal act and geological trace analysis and evidence. Forensic geologists may assist the police and law enforcement in a range of ways including for example; homicide, sexual assaults, counter terrorism, kidnapping, humanitarian incidents, environmental crimes, precious minerals theft, fakes and fraudulent crimes. The objective of this paper is to consider the geoethical aspects of forensic geology. This includes both delivery to research and teaching, and contribution to the practical applications of forensic geology in case work. The case examples cited are based on the personal experiences of the authors. Often, the technical and scientific aspect of forensic geology investigation may be the most straightforward, after all, this is what the forensic geologist has been trained to do. The associated geoethical issues can be the most challenging and complex to manage. Generally, forensic geologists are driven to carry-out their research or case work with integrity, honesty and in a manner that is law abiding, professional, socially acceptable and highly responsible. This is necessary in advising law enforcement organisations, society and the scientific community that they represent. As the science of forensic geology begins to advance around the world it is desirable to establish a standard set of principles, values and to provide an agreed ethical a framework. But what are these core values? Who is responsible for producing these? How may these become enforced? What happens when geoethical standards are breached? This paper does not attempt to provide all of the answers, as further work

In doing this we have consulted practitioners across a range of forensic disciplines, and critically compared IBA with conventional characterisation techniques to investigate the areas in which IBA can add evidential value. In this talk, the results of this feasibility study will be presented, showing the types of sample for which IBA shows considerable promise. We will show how a combination of PIXE with other IBA techniques (EBS, PIGE, MeV-SIMS) can be used to give unprecedented characterisation of forensic samples and comment on the significance of these results for forensic casework. We will also show cases where IBA not appear to add any significant improvement over conventional techniques. (author)

  7. A forensic science perspective on the role of images in crime investigation and reconstruction.

    Milliet, Quentin; Delémont, Olivier; Margot, Pierre

    2014-12-01

    This article presents a global vision of images in forensic science. The proliferation of perspectives on the use of images throughout criminal investigations and the increasing demand for research on this topic seem to demand a forensic science-based analysis. In this study, the definitions of and concepts related to material traces are revisited and applied to images, and a structured approach is used to persuade the scientific community to extend and improve the use of images as traces in criminal investigations. Current research efforts focus on technical issues and evidence assessment. This article provides a sound foundation for rationalising and explaining the processes involved in the production of clues from trace images. For example, the mechanisms through which these visual traces become clues of presence or action are described. An extensive literature review of forensic image analysis emphasises the existing guidelines and knowledge available for answering investigative questions (who, what, where, when and how). However, complementary developments are still necessary to demystify many aspects of image analysis in forensic science, including how to review and select images or use them to reconstruct an event or assist intelligence efforts. The hypothetico-deductive reasoning pathway used to discover unknown elements of an event or crime can also help scientists understand the underlying processes involved in their decision making. An analysis of a single image in an investigative or probative context is used to demonstrate the highly informative potential of images as traces and/or clues. Research efforts should be directed toward formalising the extraction and combination of clues from images. An appropriate methodology is key to expanding the use of images in forensic science.

    We now have a confusing set of five commonly used terms for the application of Earth evidence in forensic science. This confusion is resulting in Earth scientists who use these methods mentioning different terms, sometimes for the same type of study. Likewise, forensic scientists, police/law enforcement officers and those employed by courts of law are becoming confused as to what each term means. A nomenclatural framework (based on the first use of each term) is proposed to encourage consistency in the use of terminology. Generally, the number of Earth science applications has grown through time, from soil and sediment analysis to remote sensing and GIS. The issue of where forensic biology and microbiology sits with these uses of Earth evidence is considered. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    Forensic entomology, the use of insects and other arthropods in forensic investigations, is becoming increasingly more important in such investigations. To ensure its optimal use by a diverse group of professionals including pathologists, entomologists and police officers, a common frame of guidelines and standards is essential. Therefore, the European Association for Forensic Entomology has developed a protocol document for best practice in forensic entomology, which includes an overview of equipment used for collection of entomological evidence and a detailed description of the methods applied. Together with the definitions of key terms and a short introduction to the most important methods for the estimation of the minimum postmortem interval, the present paper aims to encourage a high level of competency in the field of forensic entomology.

  10. DNA typing in forensic medicine and in criminal investigations: a current survey

    Science.gov (United States)

    Benecke, Mark

    Since 1985 DNA typing of biological material has become one of the most powerful tools for personal identification in forensic medicine and in criminal investigations [1-6]. Classical DNA "fingerprinting" is increasingly being replaced by polymerase chain reaction (PCR) based technology which detects very short polymorphic stretches of DNA [7-15]. DNA loci which forensic scientists study do not code for proteins, and they are spread over the whole genome [16, 17]. These loci are neutral, and few provide any information about individuals except for their identity. Minute amounts of biological material are sufficient for DNA typing. Many European countries are beginning to establish databases to store DNA profiles of crime scenes and known offenders. A brief overview is given of past and present DNA typing and the establishment of forensic DNA databases in Europe.

    Management of a crime is the process of ensuring accurate and effective collection and preservation of physical evidence. Forensic botany can provide significant supporting evidences during criminal investigations. The aim of this study is to demonstrate the importance of forensic botany in the crime scene. We reported a case of a woman affected by dementia who had disappeared from nursing care and was found dead near the banks of a river that flowed under a railroad. Two possible ways of access to crime scene were identified and denominated "Path A" and "Path B." Both types of soil and plants were identified. Botanical survey was performed. Some samples of Xanthium Orientalis subsp. Italicum were identified. The fall of woman resulted in external injuries and vertebral fracture at autopsy. The botanical evidence is important when crime scene and autopsy findings are not sufficient to define the dynamics and the modality of death. © 2014 American Academy of Forensic Sciences.

    The principal aims of this study are to identify risk factors associated with police arrest and false confessions and to investigate whether the severity of the ADHD condition/symptoms increases the risk. 22,226 young persons in Iceland anonymously completed self-report questionnaires screening for conduct disorder and ADHD. In addition, they stated whether they had a diagnosis of ADHD and had received ADHD medication, and their history of offending, police interrogation and false confession. Participants were stratified into two age groups, 14-16 and 17-24 years. The older group was significantly more likely to have been interrogated by the police but the younger group were much more vulnerable to false confession during interrogation. Males were more likely to be at risk for both than females. The severity of the ADHD condition increased the risk of both interrogation and false confession. Negative binomial regressions showed that age, gender, conduct disorder, offending, and ADHD symptoms were all significant predictors of both interrogations and number of false confessions. Conduct disorder was the single best predictor of police interrogation, but the findings were more mixed regarding false confessions. Young people presenting with a combination of severe ADHD and comorbid conduct disorder had the worst outcome for both interrogation and false confessions. The findings endorse the need for support of persons with ADHD to be put in place to ensure fair due process and to prevent miscarriages of justice.

  14. The role of forensic death investigators interacting with the survivors of death by homicide and suicide.

    Baumann, Robin; Stark, Sharon

    2015-01-01

    When sudden unexpected death occurs, an investigation ensues in an attempt to discover the cause and manner of death. Autopsies are performed when reasons for death are not obvious. They are used to provide information, confirm the cause of death, and/or reveal conditions not recognized before death (Hendricks, 2011). One important reason for performing an autopsy is to help families to understand what happened to their loved one so that they can begin the process of grieving. The way that the initial notification and investigation is handled can have a bearing on how a family's grief progresses. Forensic nurses are in a unique position to bring a holistic approach to death investigation with a focus of care that includes not only the decedent but the surviving loved ones as well (Koehler, 2008). Forensic nurse death investigators can assist families through initial stages of grief in the investigation of death.

    Police investigations of the Italian Ministry of Treasury Police involving the illicit sale of tobacco lead to the confiscation of large quantities of smuggled cigarettes. Thousands of tons of cigarettes of different manufacturers are sequestrated yearly in many regions of Italy and different criminal organizations have been identified as unlawful importers. In order to verify whether the recovered smuggled lots of cigarettes come from the official manufacturers, or they have produced illicitly, usually chemical analysis are carried out. By the determination of trace elements content, specific information can be obtained by comparing different brands of cigarettes and different batches of tobacco. Samples of tobacco of cigarettes manufactured by the Italian State Monopoly, taken as 'reference samples', have been compared with those of illicit origin. Elements such as Co, Br, Cr and Sc have been found to be useful for the selective characterization. The results, submitted to statistical elaboration, provided important information on the origin of smuggled cigarettes. (author)

  19. THE LOSS OF MALAYSIA AIRLINES FLIGHT MH17: A FORENSIC AND HUMANITARIAN TASK.

    Ranson, David

    2015-06-01

    While forensic medical tasks are usually associated with supporting the criminal justice system, there are a range of forensic medical skills that can be brought to bear on addressing humanitarian activities. Disaster victim identification is a procedure that has achieved international standardisation through the work of a multinational Interpol Standing Committee. While part of a police organisation, it includes forensic pathologists, anthropologists, odontologists and molecular biologists who provide most of the specialist scientific input regarding identification that is integrated with police processes such as document examination and fingerprinting. The loss of Malaysian Airlines Flight MH17 represented a major activation of these procedures in an environment that had both humanitarian and forensic criminal investigation components. The information that is derived from the processes involved in disaster victim identification has a value that goes far beyond the determination of identity. It has an important humanitarian role in supporting the family and friends of the victims in their bereavement journey.

    The pursuit and reception of a confession during police interrogation and cross examination lead to a dynamic interaction between interrogator and interrogated which can be examined under the light of psychoanalytical concepts. This reference framework enables a reading of the different positions occupied by the interrogator with regard to the interrogated, and allows to understand certain mechanisms in the arrival of a confession as well as some of its effects.

  3. Medicolegal Investigation of Medical Negligence in India: A Report of Forensic Autopsy Case

    Full Text Available In general negligence means failure to take proper care over something and according to law negligence means breach of a duty of care which results in damage. Medical negligence is not very uncommon; every now and then cases of medical negligence are reported in the electronic media. Medical Negligence is doing something that one is not supposed to do, or failing to do something that one is supposed to do. Role of Forensic Pathologist in cases of Medical Negligence is always unquestionable. Forensic Pathologists need to explore and maintain a high degree of transparency between the doctors, patients and the law enforcing agencies. In the present case, a person was attacked by a wild animal and he fell down on a rough surface. Immediately he was rushed to a local hospital. The treating doctor stitched the external injury and allowed him to go home; he neither advised any investigation nor kept him under observation to rule out any internal injury. After 12 hours the victim succumbed to death. At autopsy a fractured skull with underlying subdural haemorrhage was noticed. Was not the treating doctor negligent in this case? Were the protocols followed? What should be the role of a Forensic Pathologist in such kind of cases?

  4. Microbial population analysis improves the evidential value of faecal traces in forensic investigations.

    2017-01-01

    The forensic science community has a growing interest in microbial population analysis, especially the microbial populations found inside and on the human body. Both their high abundance, microbes outnumber human cells by a factor 10, and their diversity, different sites of the human body harbour different microbial communities, make them an interesting tool for forensics. Faecal material is a type of trace evidence which can be found in a variety of criminal cases, but is often being ignored in forensic investigations. Deriving a human short tandem repeat (STR) profile from a faecal sample can be challenging. However, the microbial communities within faecal material can be of additional criminalistic value in linking a faecal trace to the possible donor. We present a microarray technique in which the faecal microbial community is used to differentiate between faecal samples and developed a decision model to predict the possible common origin of questioned samples. The results show that this technique may be a useful additional tool when no or only partial human STR profiles can be generated.

    2010-01-01

    This review discusses the methodology of nuclear forensics and illicit trafficking of nuclear materials. Nuclear forensics is relatively new scientific branch whose aim it is to read out material inherent from nuclear material. Nuclear forensics investigations have to be considered as part of a comprehensive set of measures for detection,interception, categorization and characterization of illicitly trafficking nuclear material. Prevention, detection and response are the main elements in combating illicit trafficking. Forensics is a key element in the response process. Forensic science is defined as the application of a broad spectrum of sciences to answer questions of interest to the legal system. Besides, in this study we will explain age determination of nuclear materials.

    2015-01-01

    The use of therapy animals during forensic interviews for child sexual abuse allegations is a recommendation by the Therapy Animals Supporting Kids Program to help ease children's discomfort during the forensic interview process. Based on this recommendation, this study incorporated a certified therapy canine into the forensic interview process for child sexual abuse allegations. This study investigated changes in salivary cortisol, immunoglobulin A, blood pressure, and heart rate as a result of forensic interview phenomenon (e.g., outcry) incorporating animal-assisted intervention versus a control condition in children (N = 42) interviewed for alleged child sexual abuse. The results supported significantly greater heart rate values for the control group (n = 23) who experienced sexual contact and/or indecency than the experience of aggravated sexual assault compared to no difference in HR for the intervention group (n = 19). The results suggest that the presence of the canine in the forensic interview may have acted as a buffer or safeguard for the children when disclosing details of sexual abuse. In the intervention group, children's HR was lower at the start of the forensic interview compared to the control group. Finding an effect of having a certified handler-canine team available during the forensic interview on physiological measures of stress has real-world value for children, child welfare personnel, and clinical therapists. It is suggested that animal-assisted intervention be expanded to children facing other types of trauma and to treatment programs for child survivors of sexual abuse.

    Full Text Available Introduction: Our study examines the frequency of joint investigations by child protection workers and the police in sexual abuse investigations compared to other maltreatment types and the association of child-, caregiver-, maltreatment- and investigation-related characteristics in joint investigations, focussing specifically on investigations involving sexual abuse. Methods: We analyzed data from the Canadian Incidence Study of Reported Child Abuse and Neglect-2008 using logistic regression. Results: The data suggest that sexual abuse (55%, and then physical abuse, neglect and emotional maltreatment, are most often co-investigated. Substantiation of maltreatment, severity of maltreatment, placement in out-of-home care, child welfare court involvement and referral of a family member to specialized services was more likely when the police were involved in an investigation. Conclusion: This study adds to the limited information on correlates of joint child protection agency and police investigations. Further research is needed to determine the effectiveness of these joint investigations.

    The death investigation system in Japan is in the midst of a great transformation. As part of efforts to revise this system, in this study we analyzed the reasons the police refer unnatural death cases for forensic autopsy and, from an understanding of the trends of such referrals, we discuss the future direction of handling unnatural deaths in our country. For 1618 forensic autopsy cases handled by the First Investigation Division of Chiba Prefectural Police that were referred to our institution for forensic autopsy between 2003 and 2012, we tallied the number of autopsies by sex, age group, and reason for forensic autopsy for each year and investigated trends in the referrals over time. The results revealed that the number of autopsies increased annually from 2003 to 2012, with a marked increase from 2010. The number of autopsies increased particularly for cases of suspected criminal deaths, where it was unclear to the police before the forensic autopsy whether or not the death resulted from a criminal act. Our findings suggest that the number of forensic autopsies will continue to increase into the future in Chiba prefecture, and is a trend that is inevitable if we are to prevent criminal death cases from being overlooked. Although referrals for forensic autopsy in Japan are made only when criminal activity is suspected, the original purpose of death investigations is not only to avoid overlooking crimes, but also to flag public health issues. Therefore, together with the police, we need to review the original purpose and conduct more in-depth discussions about when referrals are necessary. Copyright © 2014 Elsevier Ireland Ltd.

    2017-07-01

    This review describes the social and ethical responses to the history of innovations in forensic genetics and their application to criminal investigations. Following an outline of the three recurrent social perspectives that have informed these responses (crime management, due process, and genetic surveillance), it goes on to introduce the repertoire of ethical considerations by describing a series of key reports that have shaped subsequent commentaries on forensic DNA profiling and databasing. Four major ethical concerns form the focus of the remainder of the paper (dignity, privacy, justice, and social solidarity), and key features of forensic genetic practice are examined in the light of these concerns. The paper concludes with a discussion of the concept of "proportionality" as a resource for balancing the social and ethical risks and benefits of the use of forensic genetics in support of criminal justice.

    Estimation of the radiation released during nuclear accidents or radiological terrorist events is imperative for the prediction of health effects following such an exposure. In addition, in several cases there is a need to identify the prior presence of radioactive materials at buildings or sites (nuclear forensics). To this direction, several materials have been the research object of numerous studies the last decade in an attempt to identify potentially new retrospective/accidental/forensic dosimeters. However, the studies targeting biological materials are limited and their majority is mainly focused on the luminescence behavior of human biological material. Consequently, the use of such materials in retrospective dosimetry presumes the exposure of humans in the radiation field. The present work constitutes the first attempt to seek non-human biological materials, which can be found in nature in abundance or in/on other living organisms. To this end, the present work investigates the basic optically stimulated luminescence behavior of insect wings, which exhibit several advantages compared to other materials. Insects are ubiquitous, have a short life expectancy and exhibit a low decomposition rate after their death. Findings of the present study are encouraging towards the potential use of insects' wings at retrospective/accidental/forensic dosimetry, since they exhibit linear OSL response over a wide dose range and imperceptible loss of signal several days after their irradiation when they are kept in dark. On the other hand, the calculated lower detection limit is not low enough to allow their use as emergency dosimeters when individuals are exposed to non-lethal doses. In addition, wings exhibit strong optical fading when they are exposed to daylight and thus special care should be taken during the sampling procedure in order to use the wings as accidental/forensic dosimeters, by seeking (dead) insects in dark places, such as behind furniture, equipment or in

  11. Analysis of plant soil seed banks and seed dispersal vectors: Its potential and limits for forensic investigations.

    Plant seeds exhibit many species-specific traits, thus potentially being especially helpful for forensic investigations. Seeds of a broad range of plant species occur in soil seed banks of various habitats and may become attached in large quantities to moving objects. Although plant seeds are now routinely used as trace evidence in forensic practice, only scant information has been published on this topic in the scientific literature. Thus, the standard methods remain unknown to specialists in such botanical subjects as plant ecology and plant geography. These specialists, if made aware of the forensic uses of seeds, could help in development of new, more sophisticated approaches. We aim to bridge the gap between forensic analysts and botanists. Therefore, we explore the available literature and compare it with our own experiences to reveal both the potential and limits of soil seed bank and seed dispersal analysis in forensic investigations. We demonstrate that habitat-specific and thus relatively rare species are of the greatest forensic value. Overall species composition, in terms of species presence/absence and relative abundance can also provide important information. In particular, the ecological profiles of seeds found on any moving object can help us identify the types of environments through which the object had travelled. We discuss the applicability of this approach to various European environments, with the ability to compare seed samples with georeferenced vegetation databases being particularly promising for forensic investigations. We also explore the forensic limitations of soil seed bank and seed dispersal vector analyses. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Age estimation remains one of the most challenging tasks in forensic practice when establishing a biological profile of unknown skeletonised remains. Morphological methods based on developmental markers of bones can provide accurate age estimates at a young age, but become highly unreliable for ages over 35 when all developmental markers disappear. This study explores the changes in the biomechanical properties of bone tissue and matrix, which continue to change with age even after skeletal maturity, and their potential value for age estimation. As a proof of concept we investigated the relationship of 28 variables at the macroscopic and microscopic level in rib autopsy samples from 24 individuals. Stepwise regression analysis produced a number of equations one of which with seven variables showed an R2 = 0.949; a mean residual error of 2.13 yrs ±0.4 (SD) and a maximum residual error value of 2.88 yrs. For forensic purposes, by using only bench top machines in tests which can be carried out within 36 hrs, a set of just 3 variables produced an equation with an R2 = 0.902 a mean residual error of 3.38 yrs ±2.6 (SD) and a maximum observed residual error 9.26yrs. This method outstrips all existing age-at-death methods based on ribs, thus providing a novel lab based accurate tool in the forensic investigation of human remains. The present application is optimised for fresh (uncompromised by taphonomic conditions) remains, but the potential of the principle and method is vast once the trends of the biomechanical variables are established for other environmental conditions and circumstances.

    Python snake species are often encountered in illegal activities and the question of species identity can be pertinent to such criminal investigations. Morphological identification of species of pythons can be confounded by many issues and molecular examination by DNA analysis can provide an alternative and objective means of identification. Our paper reports on the development and validation of a PCR primer pair that amplifies a segment of the mitochondrial cytochrome b gene that has been suggested previously as a good candidate locus for differentiating python species. We used this DNA region to perform species identification of pythons, even when the template DNA was of poor quality, as might be the case with forensic evidentiary items. Validation tests are presented to demonstrate the characteristics of the assay. Tests involved the cross-species amplification of this marker in non-target species, minimum amount of DNA template required, effects of degradation on product amplification and a blind trial to simulate a casework scenario that provided 100% correct identity. Our results demonstrate that this assay performs reliably and robustly on pythons and can be applied directly to forensic investigations where the presence of a species of python is in question.

    In early 2009, a state policing agency raided a clandestine drug laboratory in a suburb of a major city in Australia. While searching the laboratory, they discovered a small glass jar labelled 'Gamma Source' and containing a green powder. The powder was radioactive. This paper documents the detailed nuclear forensic analysis undertaken to characterize and identify the material and determine its provenance. Isotopic and impurity content, phase composition, microstructure and other characteristics were measured on the seized sample, and the results were compared with similar material obtained from the suspected source (ore and ore concentrate material). While an extensive range of parameters were measured, the key 'nuclear forensic signatures' used to identify the material were the U isotopic composition, Pb and Sr isotope ratios, and the rare earth element pattern. These measurements, in combination with statistical analysis of the elemental and isotopic content of the material against a database of uranium ore concentrates sourced from mines located worldwide, led to the conclusion that the seized material (a uranium ore concentrate of natural isotopic abundance) most likely originated from Mary Kathleen, a former Australian uranium mine

    Bitzer, Sonja; Albertini, Nicola; Lock, Eric; Ribaux, Olivier; Delémont, Olivier

    2015-12-01

    In an attempt to grasp the effectiveness of forensic science in the criminal justice process, a number of studies introduced some form of performance indicator. However, most of these indicators suffer from different weaknesses, from the definition of forensic science itself to problems of reliability and validity. We suggest the introduction of the concept of utility of the clue as an internal evaluation indicator of forensic science in the investigation. Utility of the clue is defined as added value of information, gained by the use of traces. This concept could be used to assess the contribution of the trace in the context of the case. By extension, a second application of this concept is suggested. By formalising and considering, a priori, the perceived utility of using traces, we introduce the notion of expected utility that could be used as decision factor when choosing which traces to use, once they have been collected at the crime scene or from an object in the laboratory. In a case-based approach, utility can be assessed in the light of the available information to evaluate the investigative contribution of forensic science. In the decision-making process, the projection or estimation of the utility of the clue is proposed to be a factor to take into account when triaging the set of traces.

    Dr. Marcel Leclercq was a pioneer in the field of forensic entomology. He has provided his knowledge of insect biology to many forensic cases, and most of them have found the way to publication. Most of the articles he has written were focused on individual cases, and despite the abundance of entomoforensic investigations he conducted, no synthesis has been published. This article summarizes 36 yr of forensic entomological investigations in temperate Europe, mainly in Belgium. Dr. Leclercq's work includes 132 entomological cases involving 141 human corpses found in various death scenes. Under certain conditions, insect specimens found at death scene can provide information on when (postmortem interval estimation), where and how a person died. More or less 100 insect species associated with a dead body have been identified by Dr. Leclercq.

  2. Attitudes in Korea toward Introducing Smart Policing Technologies: Differences between the General Public and Police Officers

    2017-10-01

    Full Text Available This study analyzes different attitudes toward introduction of smart policing technologies in cybercrime policing among the Korean public and police. Policing is essential for a sustainable community. Technological advances in policing have both positive and negative aspects, making it essential to investigate perceptions of both public and police when introducing smart policing technologies. A discrete choice experiment was undertaken to survey preferences of the public and police toward introduction of such technologies and conduct simulation analysis to compare changes in the acceptance of various scenarios. The study divides cybercrime policing into prevention and investigation. The sample included 500 members of the public and 161 police officers. The results show that the public thinks an increase in yearly taxes and invasion of privacy are the most important factors. Conversely, the police think factors enhancing the efficiency of policing are most important. Moreover, when smart policing technologies are introduced, the public and police perceive more utility in the prevention and investigation of cybercrime, respectively. Few studies in this field separate the prevention and investigation of crimes, or compare perceptions of the public and police toward the introduction of smart policing technologies. This study’s quantitative analysis provides insights lacking in previous literature.

  3. Atomic force microscopic investigation of commercial pressure sensitive adhesives for forensic analysis.

    2011-07-15

    Pressure sensitive adhesive (PSA), such as those used in packaging and adhesive tapes, are very often encountered in forensic investigations. In criminal activities, packaging tapes may be used for sealing packets containing drugs, explosive devices, or questioned documents, while adhesive and electrical tapes are used occasionally in kidnapping cases. In this work, the potential of using atomic force microscopy (AFM) in both imaging and force mapping (FM) modes to derive additional analytical information from PSAs is demonstrated. AFM has been used to illustrate differences in the ultrastructural and nanomechanical properties of three visually distinguishable commercial PSAs to first test the feasibility of using this technique. Subsequently, AFM was used to detect nanoscopic differences between three visually indistinguishable PSAs. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

  4. An overview to the investigative approach to species testing in wildlife forensic science

    Science.gov (United States)

    2011-01-01

    The extent of wildlife crime is unknown but it is on the increase and has observable effects with the dramatic decline in many species of flora and fauna. The growing awareness of this area of criminal activity is reflected in the increase in research papers on animal DNA testing, either for the identification of species or for the genetic linkage of a sample to a particular organism. This review focuses on the use of species testing in wildlife crime investigations. Species identification relies primarily on genetic loci within the mitochondrial genome; focusing on the cytochrome b and cytochrome oxidase 1 genes. The use of cytochrome b gained early prominence in species identification through its use in taxonomic and phylogenetic studies, while the gene sequence for cytochrome oxidase was adopted by the Barcode for Life research group. This review compares how these two loci are used in species identification with respect to wildlife crime investigations. As more forensic science laboratories undertake work in the wildlife area, it is important that the quality of work is of the highest standard and that the conclusions reached are based on scientific principles. A key issue in reporting on the identification of a particular species is a knowledge of both the intraspecies variation and the possible overlap of sequence variation from one species to that of a closely related species. Recent data showing this degree of genetic separation in mammalian species will allow greater confidence when preparing a report on an alleged event where the identification of the species is of prime importance. The aim of this review is to illustrate aspects of species testing in wildlife forensic science and to explain how a knowledge of genetic variation at the genus and species level can aid in the reporting of results.

    Yearly, 600,000 people complete suicide in low- and middle-income countries, accounting for 75% of the world's burden of suicide mortality. The highest regional rates are in South and East Asia. Nepal has one of the highest suicide rates in the world; however, few investigations exploring patterns surrounding both male and female suicides exist. This study used psychological autopsies to identify common factors, precipitating events, and warning signs in a diverse sample. Randomly sampled from 302 police case reports over 24 months, psychological autopsies were conducted for 39 completed suicide cases in one urban and one rural region of Nepal. In the total police sample (n = 302), 57.0% of deaths were male. Over 40% of deaths were 25 years or younger, including 65% of rural and 50.8% of female suicide deaths. We estimate the crude urban and rural suicide rates to be 16.1 and 22.8 per 100,000, respectively. Within our psychological autopsy sample, 38.5% met criteria for depression and only 23.1% informants believed that the deceased had thoughts of self-harm or suicide before death. Important warning signs include recent geographic migration, alcohol abuse, and family history of suicide. Suicide prevention strategies in Nepal should account for the lack of awareness about suicide risk among family members and early age of suicide completion, especially in rural and female populations. Given the low rates of ideation disclosure to friends and family, educating the general public about other signs of suicide may help prevention efforts in Nepal.

    Often carrion decomposition studies are conducted using a single carcass or a few carcasses sampled repeatedly through time to reveal trends in succession community composition. Measurements of biomass and other abiotic parameters (e.g., temperature) are often collected on the same carcasses but are rarely a focal point of the studies. This study investigated the effects that repeated sampling during experiments have on the decomposition of carrion, measured as both gross biomass (carcass plus fauna) and net biomass (carcass only), on carcasses disturbed on every visit (with weighing only or also with the collection of fauna) and on carcasses disturbed only once. Each trial lasted at least 21 days, with samples taken in triplicate. Rat carcasses used in this study were placed in the field on the same day and either weighed on every visit or ignored until a given day. Internal and ambient air temperatures were recorded on each carcass at the time of sampling and on undisturbed carcasses using temperature loggers. The presence of succession fauna did not result in significant biomass loss on most days; however, there were individual days early in decomposition (days 3 through 6) when the succession fauna comprised a large portion of the gross biomass. With the exception of biomass loss by the emigration of maggots on days 4 and 5, neither repeated weighing of the carcasses nor repeated weighing and faunal sampling of the carcasses statistically affected the rate of biomass loss. Internal temperatures of carcasses sampled repeatedly were frequently 2-5°C lower than those that had not been disturbed, and ambient temperatures differed significantly depending on the location of measurement device. Results indicate that methods used historically for biomass loss determination in experimental forensic entomology studies are adequate, but further refinements to experimental methodology are desirable. © 2010 American Academy of Forensic Sciences.

    Investigations of any type of crime invariably starts at the crime scene by collecting evidence. Thus, the purpose of this research was to collect and analyze an entomological trace from an environment that is similar to those of indoor crime scenes. Hematophagous mosquitoes were collected from two residential units; saliva of volunteers that were residents in the units was also collected for genetic analysis as reference samples. We examined the allele frequencies of 15 short tandem repeat loci (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818, and FGA) and amelogenin. A total of 26 female hematophagous mosquitoes were identified as Aedes aegypti, Aedes albopictus, and Culex quinquefasciatus; we were able to obtain 11 forensically valid genetic profiles, with a minimum of 0.028203 ng/μL of human DNA. Thus, the results of this study showed that it was possible to correlate human genetic information from mosquitoes with the volunteer reference samples, which validates the use of this information as forensic evidence. Furthermore, we observed mixed genetic profiles from one mosquito. Therefore, it is clearly important to collect these insects indoors where crimes were committed, because it may be possible to find intact genetic profiles of suspects in the blood found in the digestive tract of hematophagous mosquitoes for later comparison to identify an offender and/or exclude suspects.

    2017-06-01

    Failures in criminal investigation may lead to wrongful convictions. Insight in the criminal investigation process is needed to understand how these investigative failures may rise and how measures can contribute to the prevention of this kind of failures. Some of the main findings of an empirical study of the criminal investigation process in four cases of major investigations are presented here. This criminal investigation process is analyzed as a process of framing, using Goffman's framing (Goffman, 1975) and interaction theories (Goffman, 1990). It shows that in addition to framing, other substantive and social factors affect the criminal investigation.

    Forensic medical practitioners need to define the general principles governing procedures to be used for the on-site examination of a body where the death has occurred in unnatural, violent or suspicious circumstances. These principles should be followed whenever a medical expert is required to perform an on-site corpse inspection and should be utilised as a set of general guidelines to be adapted to the specific situation in hand and interpreted using common sense and scientific knowledge of the relevant procedures and facts of the case. The aim of these principles is to ensure that forensic evidence at the scene of a death is properly observed and assessed and all necessary relevant evidence gathered in order to ensure that a comprehensive report is available to the judicial authority (investigating judge or coroner) in the justice system. The on-site corpse inspection by a forensic practitioner is a mandatory and essential stage of the forensic and medico-legal autopsy, as it may provide important information for subsequent investigation stages.

  14. Fire debris analysis for forensic fire investigation using laser induced breakdown spectroscopy (LIBS)

    Science.gov (United States)

    Choi, Soojin; Yoh, Jack J.

    2017-08-01

    The possibility verification of the first attempt to apply LIBS to arson investigation was performed. LIBS has capabilities for real time in-situ analysis and depth profiling. It can provide valuable information about the fire debris that are complementary to the classification of original sample components and combustion residues. In this study, fire debris was analyzed to determine the ignition source and existence of a fire accelerant using LIBS spectra and depth profiling analysis. Fire debris chemical composition and carbon layer thickness determines the possible ignition source while the carbon layer thickness of combusted samples represents the degree of sample carbonization. When a sample is combusted with fire accelerants, a thicker carbon layer is formed because the burning rate is increased. Therefore, depth profiling can confirm the existence of combustion accelerants, which is evidence of arson. Also investigation of fire debris by depth profiling is still possible when a fire is extinguished with water from fire hose. Such data analysis and in-situ detection of forensic signals via the LIBS may assist fire investigation at crime scenes.

  15. The utilization of forensic science and criminal profiling for capturing serial killers.

    2011-06-15

    Movies and nightly television shows appear to emphasize highly efficient regimens in forensic science and criminal investigative analysis (profiling) that result in capturing serial killers and other perpetrators of homicide. Although some of the shows are apocryphal and unrealistic, they reflect major advancements that have been made in the fields of forensic science and criminal psychology during the past two decades that have helped police capture serial killers. Some of the advancements are outlined in this paper. In a study of 200 serial killers, we examined the variables that led to police focusing their attention on specific suspects. We developed 12 categories that describe how serial killers come to the attention of the police. The results of the present study indicate that most serial killers are captured as a result of citizens and surviving victims contributing information that resulted in police investigations that led to an arrest. The role of forensic science appears to be important in convicting the perpetrator, but not necessarily in identifying the perpetrator. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

  16. Investigation of correlations in some chemical impurities and isotope ratios for nuclear forensic purposes

    2002-01-01

    Full text: Institute for Transuranium Elements (ITU) has worked in the area of nuclear forensic science since 1992 when the first seized sample was analysed. From the beginning the analytical tools for seized materials were adapted from safeguards measurements and from materials science. Especially in the view of the origin determination the spectrum of parameters to be taken into account had to be widened. In addition to the development of a comprehensive database on nuclear materials for power reactor fuels, experimental investigations were started to identify characteristic parameters. These systematic investigations comprised the development of methodologies for age determination of Pu and highly enriched uranium, surface roughness determination of UO 2 pellets and n( 18 O)/n( 16 O) measurements in uranium oxides. However, a more profound understanding on the nature of the characteristic chemical impurities and their propagation throughout the entire process appeared necessary in particular for uranium materials. Therefore a systematic research programme was launched in order to better understand which chemical impurities might be considered as characteristic for the origin of the base material. On the other hand some impurities are introduced intentionally during the processing of the material. These impurities might be characteristic for the process used or for the plant where the material was processed. We carried out impurity measurements on uranium ores, on intermediate products (Ammoniumdiuranate or yellow cake) and on (natural) uranium oxides, hence 'vertically' throughout the process in individual facilities. n( 18 O)/n( 16 O) ratio measurements have been proven to provide useful additional information on the geographic origin of the materials. We therefore investigated the n( 18 O)/n( 16 O) isotope ratios in these different compounds, in order to obtain further experimental evidence for a consistent set of materials reportedly originating from the same

    United States Army military police (MP) training is a 19-week course designed to introduce new recruits to basic soldiering skills, Army values and lifestyle, and law enforcement skills and knowledge. The present investigation examined injury rates and injury risk factors in MP training. At the start of training, 1,838 male and 553 female MP recruits were administered a questionnaire containing items on date of birth, height, weight, tobacco use, prior physical activity, injury history, and menstrual history. Injuries during training were obtained from electronic medical records and the training units provided data on student graduation and attrition. Successfully graduating from the course were 94.3% of the men and 83.7% of the women. Experiencing at least one injury during training were 34.2% of the men and 66.7% of the women (risk ratio (women/men) = 1.95, 95% confidence interval = 1.79-2.13). Recruits were at higher injury risk if they reported that they were older, had smoked in the past, or had performed less frequent exercise or sports prior to MP training. Men were at higher injury risk if they reported a prior injury and women were at higher risk if they reported missing at least six menstrual cycles in the last year or had previously been pregnant. The present investigation was the first to identify injury rates and identify specific factors increasing injury risk during MP training.

    2014-09-01

    Full Text Available In this paper we posit that current investigative techniques—particularly as deployed by law enforcement, are becoming unsuitable for most types of crime investigation. The growth in cybercrime and the complexities of the types of the cybercrime coupled with the limitations in time and resources, both computational and human, in addressing cybercrime put an increasing strain on the ability of digital investigators to apply the processes of digital forensics and digital investigations to obtain timely results. In order to combat the problems, there is a need to enhance the use of the resources available and move beyond the capabilities and constraints of the forensic tools that are in current use. We argue that more intelligent techniques are necessary and should be used proactively. The paper makes the case for the need for such tools and techniques, and investigates and discusses the opportunities afforded by applying principles and procedures of artificial intelligence to digital forensics intelligence and to intelligent forensics and suggests that by applying new techniques to digital investigations there is the opportunity to address the challenges of the larger and more complex domains in which cybercrimes are taking place.

    The utilization of binary markers in human individual identification is gaining ground in forensic genetics. We analyzed the polymorphisms from the first commercial indel kit Investigator DIPplex (Qiagen) in 512 individuals from Afrikaner, Indian, admixed Cape Colored, and the native Bantu Xhosa and Zulu origin in South Africa and evaluated forensic and population genetics parameters for their forensic application in South Africa. The levels of genetic diversity in population and forensic parameters in South Africa are similar to other published data, with lower diversity values for the native Bantu. Departures from Hardy-Weinberg expectations were observed in HLD97 in Indians, Admixed and Bantus, along with 6.83% null homozygotes in the Bantu populations. Sequencing of the flanking regions showed a previously reported transition G>A in rs17245568. Strong population structure was detected with Fst, AMOVA, and the Bayesian unsupervised clustering method in STRUCTURE. Therefore we evaluated the efficiency of individual assignments to population groups using the ancestral membership proportions from STRUCTURE and the Bayesian classification algorithm in Snipper App Suite. Both methods showed low cross-assignment error (0-4%) between Bantus and either Afrikaners or Indians. The differentiation between populations seems to be driven by four loci under positive selection pressure. Based on these results, we draw recommendations for the application of this kit in SA. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  1. The police state myth

    1985-01-01

    This chapter attempts to refute the assertion made by antinuclear groups that the use of nuclear energy will lead to a suppression of civil liberties in the US. The ''police state'' argument is based on the belief that the management of nuclear materials would necessitate the investigation of the stability and loyalties of their managers, and that in an instance of the theft of nuclear weapons material, police countermeasures might have to include violations of due process with regard to entry and search. It is pointed out that the screening of a person for a responsible position does not violate due process, and the fact that nuclear materials are radioactive and can be easility detected at some distance indicates that close police searches would not be necessary in the case of theft

  2. Compound-Specific Isotope Analysis of Diesel Fuels in a Forensic Investigation

    2015-02-01

    Compound-specific isotope analysis (CSIA) offers great potential as a tool to provide chemical evidence in a forensic investigation. Many attempts to trace environmental oil spills were successful where isotopic values were particularly distinct. However, difficulties arise when a large data set is analyzed and the isotopic differences between samples are subtle. In the present study, discrimination of diesel oils involved in a diesel theft case was carried out to infer the relatedness of the samples to potential source samples. This discriminatory analysis used a suite of hydrocarbon diagnostic indices, alkanes, to generate carbon and hydrogen isotopic data of the compositions of the compounds which were then processed using multivariate statistical analyses to infer the relatedness of the data set. The results from this analysis were put into context by comparing the data with the δ13C and δ2H of alkanes in commercial diesel samples obtained from various locations in the South Island of New Zealand. Based on the isotopic character of the alkanes, it is suggested that diesel fuels involved in the diesel theft case were distinguishable. This manuscript shows that CSIA when used in tandem with multivariate statistical analysis provide a defensible means to differentiate and source-apportion qualitatively similar oils at the molecular level. This approach was able to overcome confounding challenges posed by the near single-point source of origin i.e. the very subtle differences in isotopic values between the samples.

    Full Text Available The Hong Kong Police Force has undergone one of its biggest challenges in the Occupy Movement that emerged in the last year. Despite the sheer complexity of the police roles, we know little about its representations in the media coverage, and even less about the extent to which the imagery impacts of police acting as peacekeepers would have been made upon the images of police acting as crime fighters. Against this background, this empirical research aims to investigate the police image and its relation to the police’s specifically categorized duties in Hong Kong. The content analysis of local newspaper accounts is used as the research method. It is found that there would be generally negative media representations of police in the order-maintenance work whereas the police images in the crime-fighting duties could still remain positive. The reasons for these findings and their implications for the conceptions of the police role are discussed.

    Wildlife forensic science is a relatively recent development to meet the increasing need of the criminal justice system where there are investigations in alleged transgressions of either international or national legislation. This application of science draws on conservation genetics and forensic geneticists from mainstream forensic science. This review is a broad overview of the history of forensic wildlife science and some of the recent developments in forensic wildlife genetics with the application of DNA developments to nonhuman samples encountered in a forensic science investigation. The review will move from methods to look at the entire genome, when there is no previous knowledge of the species studied, through methods of species identification, using DNA to determine a possible geographic origin, through to assigning samples to a particular individual or a close genetic relative of this individual. The transfer of research methods into the criminal justice system for the investigation of wildlife crimes has been largely successful as is illustrated in the review. The review concludes with comments on the need for standardization and regulation in wildlife forensic science. Copyright © 2011 Central Police University.

    In this study, a certified plutonium metal reference material (CRM 126) with a known production history is examined using analytical methods that are commonly employed in nuclear forensics for provenancing and attribution. The measured plutonium isotopic composition and actinide assay are consistent with values reported on the reference material certificate. Model ages from U/Pu and Am/Pu chronometers agree with the documented production timeline. The results confirm the utility of these analytical methods and highlight the importance of a holistic approach for forensic study of unknown materials. (author)

    Objectives With the widespread use of DNA testing, police, death investigators, and attorneys need to be aware of the capabilities of this technology. This review provides an overview of scenarios where DNA evidence has played a major role in homicide investigations in order to highlight important educational issues for police, death investigators, forensic pathologists, and attorneys. Methods This was a nonrandom, observational, retrospective study. Data were obtained from the collective files of the authors from casework during a 15-year period, from 2000 through 2014. Results A series of nine scenarios, encompassing 11 deaths, is presented from the standpoint of the police and death investigation, the forensic pathology autopsy performance, the subsequent DNA testing of evidence, and, ultimately, the final adjudication of cases. Details of each case are presented, along with a discussion that focuses on important aspects of sample collection for potential DNA testing, especially at the crime scene and the autopsy. The presentation highlights the diversity of case and evidence types in which DNA testing played a valuable role in the successful prosecution of the case. Conclusions By highlighting homicides where DNA testing contributed to the successful adjudication of cases, police, death investigators, forensic pathologists, and attorneys will be better informed regarding the types of evidence and situations where such testing is of potential value.

  19. Policing Transgender People

    2015-04-01

    Full Text Available Police policy documents often articulate strategies and approaches that police organizations want to implement in their efforts to break down barriers with minority groups. However, most police policy documents are written for police audiences and not for members of the public. Police policy documents serve as a reflection of the aspirations of the agency and not necessarily the practice of the officers. Differential policing has been a salient experience for members of transgender communities because, as individuals who express gender in ways that deviate from the norm, they have experienced numerous documented cases of police mismanaged practice. In Australia, achieving police reform in the area of policing of diverse community groups has been difficult as new initiatives implemented to educate police officers about diverse groups such as transgender communities are scarce. My study sought to analyze a police policy document to assess how one police agency’s policy aspires to shape police contact/experiences with transgender people and how this document might shape intergroup identity differences between transgender people and the police. It is argued that the policy document will negatively affect police perceptions of transgender people and may enhance adverse perceptions of intergroup difference between police and transgender people. I also argue that using this document to achieve police reform in the area of policing of transgender people will be problematic as the policy document lacks substantial procedural guidelines regarding interaction with transgender people and may not favorably constrain discretionary police power.

  20. [The CSI effect and its impact on the perceptions of forensic science experts' work].

    The issue that has been analyzed in this work is the potential effect of crime films and TV series on people's perceptions of forensic medicine and science, and especially on the forming of expectations towards forensic science experts. This syndrome is being called the "CSI effect" after the popular franchise Crime Scene Investigation (CSI). Questionnaire surveys that have been conducted included "experts": 50 experts in various specialities, 77 prosecutors, 119 judges, 64 lay judges, 161 police staff and 80 members of general public. In-depth interviews have been conducted with 20 police staff, and also a focus group has been carried out with 15 law students. In the opinion of the respondents, people's perceptions and expectations of forensic science--as it can be observed during criminal trials--are largely inflated by the entertainment media. Among the surveyed persons, the category that declares watching crime series most rarely, is forensic science experts. Around half of the surveyed experts pointed out to excessive expectations towards they work instigated by TV crime series. The most common expectations towards forensic medicine experts are: immediate conclusiveness of post mortem examinations (going as far as indicating the cause of death at the crime scene), precision of death time estimation and a routine use of sophisticated methods known from TV.

    Full Text Available The application schema layer of a Database Management System (DBMS can be modified to deliver results that may warrant a forensic investigation. Table structures can be corrupted by changing the metadata of a database or operators of the database can be altered to deliver incorrect results when used in queries. This paper will discuss categories of possibilities that exist to alter the application schema with some practical examples. Two forensic environments are introduced where a forensic investigation can take place in. Arguments are provided why these environments are important. Methods are presented how these environments can be achieved for the application schema layer of a DBMS. A process is proposed on how forensic evidence should be extracted from the application schema layer of a DBMS. The application schema forensic evidence identification process can be applied to a wide range of forensic settings.

  2. Forensic Excavation of Rock Masses: A Technique to Investigate Discontinuity Persistence

    Science.gov (United States)

    Shang, J.; Hencher, S. R.; West, L. J.; Handley, K.

    2017-11-01

    True persistence of rock discontinuities (areas with insignificant tensile strength) is an important factor controlling the engineering behaviour of fractured rock masses, but is extremely difficult to quantify using current geological survey methodologies, even where there is good rock exposure. Trace length as measured in the field or using remote measurement devices is actually only broadly indicative of persistence for rock engineering practice and numerical modelling. Visible traces of discontinuities are treated as if they were open fractures within rock mass classifications, despite many such traces being non-persistent and actually retaining considerable strength. The common assumption of 100% persistence, based on trace length, is generally extremely conservative in terms of strength and stiffness, but not always so and may lead to a wrong prediction of failure mechanism or of excavatability. Assuming full persistence would give hopelessly incorrect predictions of hydraulic conductivity. A new technique termed forensic excavation of rock masses is introduced, as a procedure for directly investigating discontinuity persistence. This technique involves non-explosive excavation of rock masses by injecting an expansive chemical splitter along incipient discontinuities. On expansion, the splitter causes the incipient traces to open as true joints. Experiments are described in which near-planar rock discontinuities, through siltstone and sandstone, were opened up by injecting the splitter into holes drilled along the lines of visible traces of the discontinuities in the laboratory and in the field. Once exposed the surfaces were examined to investigate the pre-existing persistence characteristics of the incipient discontinuities. One conclusion from this study is that visible trace length of a discontinuity can be a poor indicator of true persistence (defined for a fracture area with negligible tensile strength). An observation from this series of experiments

  3. Effect of investigator disturbance in experimental forensic entomology: succession and community composition.

    Carrion insect succession studies have historically used repeated sampling of single or a few carcasses to produce data, either weighing the carcasses, removing a qualitative subsample of the fauna present, or both, on every visit over the course of decomposition and succession. This study, conducted in a set of related experimental hypotheses with two trials in a single season, investigated the effect that repeated sampling has on insect succession, determined by the number of taxa collected on each visit and by community composition. Each trial lasted at least 21 days, with daily visits on the first 14 days. Rat carcasses used in this study were all placed in the field on the same day, but then either sampled qualitatively on every visit (similar to most succession studies) or ignored until a given day of succession, when they were sampled qualitatively (a subsample) and then destructively sampled in their entirety. Carcasses sampled on every visit were in two groups: those from which only a sample of the fauna was taken and those from which a sample of fauna was taken and the carcass was weighed for biomass determination. Of the carcasses visited only once, the number of taxa in subsamples was compared to the actual number of taxa present when the carcass was destructively sampled to determine if the subsamples adequately represented the total carcass fauna. Data from the qualitative subsamples of those carcasses visited only once were also compared to data collected from carcasses that were sampled on every visit to investigate the effect of the repeated sampling. A total of 39 taxa were collected from carcasses during the study and the component taxa are discussed individually in relation to their role in succession. Number of taxa differed on only one visit between the qualitative subsamples and the actual number of taxa present, primarily because the organisms missed by the qualitative sampling were cryptic (hidden deep within body cavities) or rare (only

  4. Diversity Policing–Policing Diversity: Performing Ethnicity in Police and Private-Security Work in Sweden

    Directory of Open Access Journals (Sweden)

    Cecilia Hansen Löfstrand

    2014-09-01

    Full Text Available This article draws upon two separate studies on policing in Sweden, both investigating “ethnic diversity” as a discourse and a practice in the performance of policing functions: one interview study with minority police officers from a county police authority and one ethnographic study of private security officers. To examine how “diversity policing” and the “policing of diversity” are performed by policing actors, their strategic reliance on an ethnically diverse workforce is examined. The official discourse in both contexts stressed “diversity policing” as a valuable resource for the effective execution of policing tasks and the legitimation of policing functions. There was, however, also another, more unofficial discourse on ethnicity that heavily influenced the policing agents’ day-to-day work. The resulting practice of “policing diversity” involved situated activities on the ground through which “foreign elements” in the population were policed using ethnicized stereotypes. Diversity in the policing workforce promoted the practice of ethnic matching, which, ironically, in turn perpetuated stereotypical thinking about Swedish “others”. A conceptual framework is developed for understanding the policing strategies involved and the disjuncture found between the widely accepted rationalities for recruiting an ethnically diverse workforce and the realities for that workforce’s effective deployment at the street level.

  5. Investigating CSI: portrayals of DNA testing on a forensic crime show and their potential effects.

    Ley, Barbara L; Jankowski, Natalie; Brewer, Paul R

    2012-01-01

    The popularity of forensic crime shows such as CSI has fueled debate about their potential social impact. This study considers CSI's potential effects on public understandings regarding DNA testing in the context of judicial processes, the policy debates surrounding crime laboratory procedures, and the forensic science profession, as well as an effect not discussed in previous accounts: namely, the show's potential impact on public understandings of DNA and genetics more generally. To develop a theoretical foundation for research on the "CSI effect," it draws on cultivation theory, social cognitive theory, and audience reception studies. It then uses content analysis and textual analysis to illuminate how the show depicts DNA testing. The results demonstrate that CSI tends to depict DNA testing as routine, swift, useful, and reliable and that it echoes broader discourses about genetics. At times, however, the show suggests more complex ways of thinking about DNA testing and genetics.

  6. The use of mitochondrial DNA (mtDNA-investigations in Forensic Sciences

    1996-07-01

    Full Text Available A variety of methods was developed to characterize mtDNA. The initial aim of these techniques was to try and link diseases with specific mitochondrial defects. As a result of the maternal inheritance trait of mtDNA these techniques facilitate studies of the phylogenetic history and population structure of the human population. It has been shown that mitochondrial DNA typing can be of great value for human identification in forensic cases. The identification of victims of mass-disasters or mass-murders, where human remains can be recovered only after many years have passed, is one of the most challenging fields of forensic identification. By using automated DNA sequencing with fluorescent labels, mitochondrial DNA sequences can be generated rapidly and accurately. Computer software facilitates the rapid comparison of individual and reference sequences.

    2017-11-01

    Now approximately 30years old, the field of digital forensics is arguably facing some of its greatest challenges to date. Whilst currently supporting law enforcement in numerous criminal cases annually, questions are beginning to emerge regarding whether it can sustain this contribution, with digital crime remaining prevalent. In his first live interview in September 2015, Head of MI5, Andrew Parker indicated that individuals are now engaging in computing acts which are beyond the control of authorities, confirming earlier remarks made by British Prime Minister David Cameron in the wake of the Charlie Hebdo attacks. Such comments cast doubt on the future effectiveness of the digital forensic discipline and its ability to effectively investigate those who implement the latest forms of technology to carry out illicit acts. This article debates the controversial question, could we be facing an era where digital crime can no longer be effectively policed? Copyright © 2017 The Chartered Society of Forensic Sciences.

    The development of forensic intelligence relies on the expression of suitable models that better represent the contribution of forensic intelligence in relation to the criminal justice system, policing and security. Such models assist in comparing and evaluating methods and new technologies, provide transparency and foster the development of new applications. Interestingly, strong similarities between two separate projects focusing on specific forensic science areas were recently observed. These observations have led to the induction of a general model (Part I) that could guide the use of any forensic science case data in an intelligence perspective. The present article builds upon this general approach by focusing on decisional and organisational issues. The article investigates the comparison process and evaluation system that lay at the heart of the forensic intelligence framework, advocating scientific decision criteria and a structured but flexible and dynamic architecture. These building blocks are crucial and clearly lay within the expertise of forensic scientists. However, it is only part of the problem. Forensic intelligence includes other blocks with their respective interactions, decision points and tensions (e.g. regarding how to guide detection and how to integrate forensic information with other information). Formalising these blocks identifies many questions and potential answers. Addressing these questions is essential for the progress of the discipline. Such a process requires clarifying the role and place of the forensic scientist within the whole process and their relationship to other stakeholders. Copyright © 2015 Elsevier Ireland Ltd.

    Handprints and dismembered hands are commonly found during crime scene investigations and disaster victim identifications, respectively. It has been indicated that the accuracy of handprint and hand measurements for estimating stature maybe population specific. Since Iban is the largest ethnic population in Sarawak, Malaysia and because the application of anthropometry of hand and handprint within this population as well as other populations within the Southeast Asian countries remain unreported, this present study that investigated the reliability and accuracy of these two anthropometric aspects acquires forensic significance. Upon measuring the height, 21 measurements were recorded on each hand and the corresponding handprint of 50 male and 52 female consented adult Iban subjects. Using univariate statistics as well as simple and multiple regression analyses, interpretation of the measurements examined here was attempted. Results revealed that lengths of hand and handprint are the more reliable traits for estimating stature in both the male and female Iban subjects (p Sarawak that may prove useful for crime scene investigations and disaster victim identifications in Malaysia.

    Forensic advisors (FA) at the National Institute for Criminalistics and Criminology (NICC), generalists in forensic science, act as an advising body to the magistrate to improve communication between the various parties involved in the investigation: magistrate, police and crime scene investigators, and forensic experts. Their role is manifold, but their main objectives are to optimise trace processing by selecting the most pertinent traces in the context of the case and by advising magistrates on the feasibility of forensic analyses in particular circumstances in regards to the latest technical advances. Despite the absence of a legal framework governing their role and involvement in judicial cases, the demand for their services has increased over the years. Initially, forensic advisors were called for complex homicide cases. Due to the proximity with the Public Prosecutor's Office, the types of offences for which their expertise was sought have become more diverse (mainly including robbery, burglary and sexual assault cases), leading to a diversity in the types of cases handled by the forensic advisors (complex, simple and review). In many of the cases they are requested for, in addition to consulting on the best analytical strategy, forensic advisors also assume the role of case coordinator regarding the seized objects and their respective analyses. Indeed, in the majority of cases treated by the FAs, two or more types of expertise have been requested and performed, either at the internal laboratories of NICC or at external laboratories. This paper explains the role of the forensic advisors in Belgium, the path that let to their current status and problems encountered. Copyright © 2017 The Chartered Society of Forensic Sciences.

    2017-07-01

    Individual age estimation is a key factor in forensic science analysis that can provide very useful information applicable to criminal, legal, and anthropological investigations. Forensic age inference was initially based on morphological inspection or radiography and only later began to adopt molecular approaches. However, a lack of accuracy or technical problems hampered the introduction of these DNA-based methodologies in casework analysis. A turning point occurred when the epigenetic signature of DNA methylation was observed to gradually change during an individual´s lifespan. In the last four years, the number of publications reporting DNA methylation age-correlated changes has gradually risen and the forensic community now has a range of age methylation tests applicable to forensic casework. Most forensic age predictor models have been developed based on blood DNA samples, but additional tissues are now also being explored. This review assesses the most widely adopted genes harboring methylation sites, detection technologies, statistical age-predictive analyses, and potential causes of variation in age estimates. Despite the need for further work to improve predictive accuracy and establishing a broader range of tissues for which tests can analyze the most appropriate methylation sites, several forensic age predictors have now been reported that provide consistency in their prediction accuracies (predictive error of ±4 years); this makes them compelling tools with the potential to contribute key information to help guide criminal investigations.

  14. War on Drugs Policing and Police Brutality.

    Cooper, Hannah L F

    2015-01-01

    War on Drugs policing has failed to reduce domestic street-level drug activity: the cost of drugs remains low and drugs remain widely available. In light of growing attention to police brutality in the United States, this paper explores interconnections between specific War on Drugs policing strategies and police-related violence against Black adolescents and adults in the United States. This paper reviews literature about (1) historical connections between race/ethnicity and policing in the United States; (2) the ways that the War on Drugs eroded specific legal protections originally designed to curtail police powers; and (3) the implications of these erosions for police brutality targeting Black communities. Policing and racism have been mutually constitutive in the United States. Erosions to the 4th Amendment to the Constitution and to the Posse Comitatus Act set the foundations for two War on Drugs policing strategies: stop and frisk and Special Weapons and Tactics (SWAT) teams. These strategies have created specific conditions conducive to police brutality targeting Black communities. Conclusions/Importance: War on Drugs policing strategies appear to increase police brutality targeting Black communities, even as they make little progress in reducing street-level drug activity. Several jurisdictions are retreating from the War on Drugs; this retreat should include restoring rights originally protected by the 4th Amendment and Posse Comitatus. While these legal changes occur, police chiefs should discontinue the use of SWAT teams to deal with low-level nonviolent drug offenses and should direct officers to cease engaging in stop and frisk.

    Full Text Available In today’s world, globalization and the increased use of information technology have resulted to the significant increases of economic crimes in recent years. Accordingly, financial crimes, such as money laundering misconducts have increased significantly. The police play active roles in the fight against money laundering and related crimes in Turkey. However, professional support is essential in order to effectively combat money laundering. In other words, not only a good level of economics, finance, accounting knowledge is critical; but also, a decent level of law information is crucial in the detection and prevention of these crimes. Increasing the effectiveness of forensic accounting profession, especially in the USA, has an important role in the prevention and detection of money laundering. Since forensic accountants have skills and capacities of litigation support, investigative accounting and expertise.

    Researchers envisioned Storage as a Service (StaaS) as an effective solution to the distributed management of digital data. Cooperative storage cloud forensic is relatively new and is an under-explored area of research. Using Symform as a case study, we seek to determine the data remnants from the use of cooperative cloud storage services. In particular, we consider both mobile devices and personal computers running various popular operating systems, namely Windows 8.1, Mac OS X Mavericks 10.9.5, Ubuntu 14.04.1 LTS, iOS 7.1.2, and Android KitKat 4.4.4. Potential artefacts recovered during the research include data relating to the installation and uninstallation of the cloud applications, log-in to and log-out from Symform account using the client application, file synchronization as well as their time stamp information. This research contributes to an in-depth understanding of the types of terrestrial artifacts that are likely to remain after the use of cooperative storage cloud on client devices. © 2016 American Academy of Forensic Sciences.

    Police officers are frequently the first responders to individuals in crisis, but generally receive little training for this role. We developed and evaluated training in suicide awareness and prevention for frontline rail police in the UK. To investigate the impact of training on officers' suicide prevention attitudes, confidence, and knowledge. Fifty-three participants completed a brief questionnaire before and after undertaking training. In addition, two focus groups were conducted with 10 officers to explore in greater depth their views and experiences of the training program and the perceived impact on practice. Baseline levels of suicide prevention attitudes, confidence, and knowledge were mixed but mostly positive and improved significantly after training. Such improvements were seemingly maintained over time, but there was insufficient power to test this statistically. Feedback on the course was generally excellent, notwithstanding some criticisms and suggestions for improvement. Training in suicide prevention appears to have been well received and to have had a beneficial impact on officers' attitudes, confidence, and knowledge. Further research is needed to assess its longer-term effects on police attitudes, skills, and interactions with suicidal individuals, and to establish its relative effectiveness in the context of multilevel interventions.

    Hormone and veterinary drug screening and forensics can benefit from the recent developments in desorption electrospray ionisation (DESI) mass spectrometry (MS). In this work the feasibility of DESI application has been studied. Using a linear ion trap or quadrupole time-of-flight (TOF) MS instrument both full-scan and data-dependent collision-induced dissociation MS n spectra were acquired in seconds without sample preparation. Preliminary data are presented for the rapid screening of (pro)hormone supplement samples, an illegal steroid cocktail and forensic samples from veterinary drug investigations. The potential of this DESI approach is clearly demonstrated since compounds observed could be independently confirmed by liquid chromatography/TOFMS with accurate mass measurement, and/or proton nuclear magnetic resonance spectroscopy. Specific concerns related to false-positive and false-negative findings due to limitations in quantification and memory-effects are briefly discussed. It is envisaged that DESI will achieve a prominent role in hormone and veterinary drug analysis in the near future

    Gilmore, Simon; Peakall, Rod; Robertson, James

    2003-01-09

    Short tandem repeat (STR) markers are the DNA marker of choice in forensic analysis of human DNA. Here we extend the application of STR markers to Cannabis sativa and demonstrate their potential for forensic investigations. Ninety-three individual cannabis plants, representing drug and fibre accessions of widespread origin were profiled with five STR makers. A total of 79 alleles were detected across the five loci. All but four individuals from a single drug-type accession had a unique multilocus genotype. An analysis of molecular variance (AMOVA) revealed significant genetic variation among accessions, with an average of 25% genetic differentiation. By contrast, only 6% genetic difference was detected between drug and fibre crop accessions and it was not possible to unequivocally assign plants as either drug or fibre type. However, our results suggest that drug strains may typically possess lower genetic diversity than fibre strains, which may ultimately provide a means of genetic delineation. Our findings demonstrate the promise of cannabis STR markers to provide information on: (1) agronomic type, (2) the geographical origin of drug seizures, and (3) evidence of conspiracy in production of clonally propagated drug crops.

  1. HIV forensics: pitfalls and acceptable standards in the use of phylogenetic analysis as evidence in criminal investigations of HIV transmission.

    Science.gov (United States)

    Bernard, E J; Azad, Y; Vandamme, A M; Weait, M; Geretti, A M

    2007-09-01

    Phylogenetic analysis - the study of the genetic relatedness between HIV strains - has recently been used in criminal prosecutions as evidence of responsibility for HIV transmission. In these trials, the expert opinion of virologists has been of critical importance. Phylogenetic analysis of HIV gene sequences is complex and its findings do not achieve the levels of certainty obtained with the forensic analysis of human DNA. Although two individuals may carry HIV strains that are closely related, these will not necessarily be unique to the two parties and could extend to other persons within the same transmission network. For forensic purposes, phylogenetic analysis should be conducted under strictly controlled conditions by laboratories with relevant expertise applying rigorous methods. It is vitally important to include the right controls, which should be epidemiologically and temporally relevant to the parties under investigation. Use of inappropriate controls can exaggerate any relatedness between the virus strains of the complainant and defendant as being strikingly unique. It will be often difficult to obtain the relevant controls. If convenient but less appropriate controls are used, interpretation of the findings should be tempered accordingly. Phylogenetic analysis cannot prove that HIV transmission occurred directly between two individuals. However, it can exonerate individuals by demonstrating that the defendant carries a virus strain unrelated to that of the complainant. Expert witnesses should acknowledge the limitations of the inferences that might be made and choose the correct language in both written and verbal testimony.

    Full Text Available Peace, security, rule of law, and sustainable development are driving principles in a democratic notion of developing country like Nepal. "3Is': Injustice, Insecurity and Imbalance have been reflecting in the post transitional Nepal. The study came with the objectives of investigating the peoples' perceptions on the adaptation of policing, the challenges and expectation. The information was collected from 1111(N respondents all over the country from different ways of life, applying mixed method questionnaire survey and interview. The research show the need of system based policing like 'intelligence-led'; 'police public partnership', and 'proactive' respectively. The influence of politicization, political instability, external influence, lack of role model leadership, open border, rampant corruption, nepotism-favoritism, lack of research are the major challenges in the security organizations. Furthermore, most educated and high profile personalities have less interest to encourage their generation in police services. People are expecting proficient and accountable police forces.

    Microscopic trace evidence includes particles from many sources such as biologicals, soil, building materials, metals, explosives, gunshot residues, and cosmetics. The particles are identified by morphological analysis, microscopy, and chemical analysis. Their identity is confirmed by comparison with reference materials or other comparison samples. The probative value of particles of forensic interest depends on their nature and the circumstances of their presence. Copyright © 2006 Central Police University.

    Here we present a nuclear forensic study of uranium from German nuclear projects which used different geometries of metallic uranium fuel. Through measurement of the {sup 230}Th/{sup 234}U ratio, we could determine that the material had been produced in the period from 1940 to 1943. To determine the geographical origin of the uranium, the rare-earth-element content and the {sup 87}Sr/{sup 86}Sr ratio were measured. The results provide evidence that the uranium was mined in the Czech Republic. Trace amounts of {sup 236}U and {sup 239}Pu were detected at the level of their natural abundance, which indicates that the uranium fuel was not exposed to any major neutron fluence.

    A stable assessment of cognition is of paramount importance for forensic psychiatric patients (FPP). The purpose of this study was to compare repeated measures of IQ scores in FPPs with and without intellectual disability. Repeated measurements of IQ scores in FPPs (n = 176) were collected. Differences between tests were computed, and each IQ score was categorized. Additionally, t-tests and regression analyses were performed. Differences of 10 points or more were found in 66% of the cases comparing WAIS-III with RAVEN scores. Fisher's exact test revealed differences between two WAIS-III scores and the WAIS categories. The WAIS-III did not predict other IQs (WAIS or RAVEN) in participants with intellectual disability. This study showed that stability or interchangeability of scores is lacking, especially in individuals with intellectual disability. Caution in interpreting IQ scores is therefore recommended, and the use of the unitary concept of IQ should be discouraged. © 2014 John Wiley & Sons Ltd.

  8. Forgotten evidence: A mixed methods study of why sexual assault kits (SAKs) are not submitted for DNA forensic testing.

    Campbell, Rebecca; Fehler-Cabral, Giannina; Bybee, Deborah; Shaw, Jessica

    2017-10-01

    Throughout the United States, hundreds of thousands of sexual assault kits (SAKs) (also termed "rape kits") have not been submitted by the police for forensic DNA testing. DNA evidence can help sexual assault investigations and prosecutions by identifying offenders, revealing serial offenders through DNA matches across cases, and exonerating those who have been wrongly accused. In this article, we describe a 5-year action research project conducted with 1 city that had large numbers of untested SAKs-Detroit, Michigan-and our examination into why thousands of rape kits in this city were never submitted for forensic DNA testing. This mixed methods study combined ethnographic observations and qualitative interviews to identify stakeholders' perspectives as to why rape kits were not routinely submitted for testing. Then, we quantitatively examined whether these factors may have affected police practices regarding SAK testing, as evidenced by predictable changes in SAK submission rates over time. Chronic resource scarcity only partially explained why the organizations that serve rape victims-the police, crime lab, prosecution, and victim advocacy-could not test all rape kits, investigate all reported sexual assaults, and support all rape survivors. SAK submission rates significantly increased once criminal justice professionals in this city had full access to the FBI DNA forensic database Combined DNA Index System (CODIS), but even then, most SAKs were still not submitted for DNA testing. Building crime laboratories' capacities for DNA testing and training police on the utility of forensic evidence and best practices in sexual assault investigations can help remedy, and possibly prevent, the problem of untested rape kits.

    2009-07-01

    Forensic chemistry is unique among chemical sciences in that its research, practice, and presentation must meet the needs of both the scientific and the legal communities. As such, forensic chemistry research is applied and derivative by nature and design, and it emphasizes metrology (the science of measurement) and validation. Forensic chemistry has moved away from its analytical roots and is incorporating a broader spectrum of chemical sciences. Existing forensic practices are being revisited as the purview of forensic chemistry extends outward from drug analysis and toxicology into such diverse areas as combustion chemistry, materials science, and pattern evidence.

  10. Forensic entomology

    Science.gov (United States)

    Amendt, Jens; Krettek, Roman; Zehner, Richard

    Necrophagous insects are important in the decomposition of cadavers. The close association between insects and corpses and the use of insects in medicocriminal investigations is the subject of forensic entomology. The present paper reviews the historical background of this discipline, important postmortem processes, and discusses the scientific basis underlying attempts to determine the time interval since death. Using medical techniques, such as the measurement of body temperature or analysing livor and rigor mortis, time since death can only be accurately measured for the first two or three days after death. In contrast, by calculating the age of immature insect stages feeding on a corpse and analysing the necrophagous species present, postmortem intervals from the first day to several weeks can be estimated. These entomological methods may be hampered by difficulties associated with species identification, but modern DNA techniques are contributing to the rapid and authoritative identification of necrophagous insects. Other uses of entomological data include the toxicological examination of necrophagous larvae from a corpse to identify and estimate drugs and toxicants ingested by the person when alive and the proof of possible postmortem manipulations. Forensic entomology may even help in investigations dealing with people who are alive but in need of care, by revealing information about cases of neglect.

  11. Estimating the uncertainty from sampling in pollution crime investigation: The importance of metrology in the forensic interpretation of environmental data.

    Barazzetti Barbieri, Cristina; de Souza Sarkis, Jorge Eduardo

    2018-07-01

    The forensic interpretation of environmental analytical data is usually challenging due to the high geospatial variability of these data. The measurements' uncertainty includes contributions from the sampling and from the sample handling and preparation processes. These contributions are often disregarded in analytical techniques results' quality assurance. A pollution crime investigation case was used to carry out a methodology able to address these uncertainties in two different environmental compartments, freshwater sediments and landfill leachate. The methodology used to estimate the uncertainty was the duplicate method (that replicates predefined steps of the measurement procedure in order to assess its precision) and the parameters used to investigate the pollution were metals (Cr, Cu, Ni, and Zn) in the leachate, the suspect source, and in the sediment, the possible sink. The metal analysis results were compared to statutory limits and it was demonstrated that Cr and Ni concentrations in sediment samples exceeded the threshold levels at all sites downstream the pollution sources, considering the expanded uncertainty U of the measurements and a probability of contamination >0.975, at most sites. Cu and Zn concentrations were above the statutory limits at two sites, but the classification was inconclusive considering the uncertainties of the measurements. Metal analyses in leachate revealed that Cr concentrations were above the statutory limits with a probability of contamination >0.975 in all leachate ponds while the Cu, Ni and Zn probability of contamination was below 0.025. The results demonstrated that the estimation of the sampling uncertainty, which was the dominant component of the combined uncertainty, is required for a comprehensive interpretation of the environmental analyses results, particularly in forensic cases.

    2010-11-01

    This paper reports on an investigation into the skills and competencies of forensic learning disability nurses in the United Kingdom. The two sample populations were forensic learning disability nurses from the high, medium, and low secure psychiatric services and non-forensic learning disability nurses from generic services. An information gathering schedule was used to collect the data; of 1200 schedules, 643 were returned for a response rate of 53.5%. The data identified the "top ten" problems that forensic learning disability nurses may encounter, the skills and competencies necessary to overcome them, and the areas that need to be developed in the future. The results indicated that the forensic learning disability nurses tended to focus on the physical aspects to the role whilst the non-forensic learning disability nurses tended to perceive the forensic role in relational terms. This has implications for practice, policy, and procedures.

    2010-11-01

    Full Text Available Sudden infant deaths syndrome (SIDS, the sudden and unexpected death of a normal and healthy infant, has remained a medical and forensic mystery. Despite years of research all attempts to ascertain the exact cause and manner of death have failed. The information collected during the course of the comprehensive investigation by the various investigation agencies and analysis of the data has not been in vain. The epidemiological, demographic, and pathological data have identified distinctive features and risk factors associated with infants that died from SIDS. Epidemiological data has provided the unique characteristics of infants that died of SIDS that differentiates them from non-SIDS infants. Analysis of information from the death scene investigation has identified key risk factor behaviour associated with SIDS, namely the prone sleeping position. Pathological examination of the internal organs, specifically the brain, has shown some differences between SIDS and non-SIDS infants. However, to gain a complete picture of SIDS data, all countries around the world must provide information, even basic information, to understand this syndrome better. Developing countries must understand their role and importance in developing plans to investigate, collect, and disseminate SIDS data to the rest of the world. This paper provides general guidelines for the investigation of SIDS in developing countries.

  2. Tattoos: forensic considerations.

    Science.gov (United States)

    Byard, Roger W

    2013-12-01

    Tattooing refers to marking of the skin by puncturing and introducing pigmented material. Although it derives from a Polynesian word, tautau, decorative tattooing has been found in most societies over many centuries. The purpose of tattooing has varied from simple decoration, to a marker of social rank, criminal and noncriminal group membership, or a particular rite of passage in tribal communities. Tattooing may be used in medicine to mark areas for radiotherapy, and may occur inadvertently associated with certain occupations such as coal mining. Forensically, tattoos may be very useful in assisting with body identification if facial features or fingers have been damaged or removed. Aspects of a decedent's history may also be deduced from certain tattoos such as military tattoos in service personnel, rudimentary line tattoos with antisocial and anti-police messages in ex-prisoners, and syringes, marihuana leaves or mushrooms in illicit drug users. Tattoos have become more common in recent years in younger individuals in the West and so should be expected to be found with increasing incidence at the time of forensic autopsy examinations. Increasing population movements also mean that less common tattoos may be encountered during forensic evaluations.

    Complainants of sexual assault may disclose to different agencies, the police and health professionals being the most likely. It is possible for certain evidence types to be collected before a clinical forensic assessment takes place that do not require the need for a Forensic Medical Practitioner. If the time frames after the incident and the nature of assault warrant the need for a forensic medical examination of either a complainant or a suspect, this should only be conducted by doctors and nurses who have received relevant, up-to-date specialist theoretical and practical training. Clear evidence shows that few other criminal offences require as extensive an examination and collection of forensic evidence as that of a sexual assault. The forensic evidence in a case may identify an assailant, eliminate a nominated suspect(s), and assist in the prosecution of a case. The elements of forensic medical examination, reviewed in this chapter, are those that are the most varied across jurisdictions around the world currently. Key focus points of this chapter are considerations for early evidence collection, utilising dedicated medical examination facilities for sample collection, contamination issues associated with evidence collection and certain practical aspects of forensic sampling methods which have evolved given results identified by Forensic Scientists processing evidential samples in sexual assault cases, Some of the problems encountered by the forensic science provider will also be discussed.

    Nuclear forensics is the investigation of nuclear materials to find evidence for example the source, the trafficking, and the enrichment of the material. The material can be recovered from various sources including dust from the vicinity of a nuclear facility, or from the radioactive debris following a nuclear explosion. Results of nuclear forensic testing are used by different organizations to make decisions. The information is typically combined with other sources of information such as law enforcement and intelligence information

    2018-01-01

    The injuries to the maxillofacial region (MFR) are among the most frequently occurring problems encountered if the forensic medical practice. The objective of the present study was the analysis of the quality of the medical record documentation of the victims of the injuries to the maxillofacial region for obtaining the information necessary for forensic medical experts to make the well-founded conclusions. We undertook the in-depth analysis of random samples from the materials stored in the archive of living subjects at the Saint-Petersburg Bureau of forensic medical expertise for the period from 2010 to 2014. The results of a total of 438 forensic medical examinations were available for the analysis. The study has demonstrated the generally low forensic medical value of the expert conclusions that frequently fail to conform to the requirements of the departmental instructions on the description of MFR injuries. In all the cases, neurologists and radiologists were counselled. The results of analysis of the drawbacks of forensic medical examinations give evidence that they originate first and foremost from subjective circumstances which opens up the promising prospects for the improvement of expertise quality based on the enhancement of the professional responsibility of the forensic medical experts.

  7. Forensic DNA phenotyping in criminal investigations and criminal courts: assessing and mitigating the dilemmas inherent in the science.

    Science.gov (United States)

    MacLean, Charles E; Lamparello, Adam

    2014-01-01

    Forensic DNA Phenotyping ("FDP"), estimating the externally visible characteristics ("EVCs") of the source of human DNA left at a crime scene, is evolving from science fiction toward science fact. FDP can already identify a source's gender with 100% accuracy, and likely hair color, iris color, adult height, and a number of other EVCs with accuracy rates approaching 70%. Patent applications have been filed for approaches to generating 3D likenesses of DNA sources based on the DNA alone. Nonetheless, criminal investigators, particularly in the United States, have been reticent to apply FDP in their casework. The reticence is likely related to a number of perceived and real dilemmas associated with FDP: is FDP racial profiling, should we test unknown and unseen physical conditions, does testing for behavioral characteristics impermissibly violate the source's privacy, ought testing be permitted for samples from known sources or DNA databases, and should FDP be limited to use in investigations only or is FDP appropriate for use in a criminal court. As this article explains, although those dilemmas are substantive, they are not insurmountable, and can be quite easily managed with appropriate regulation and protocols. As FDP continues to develop, there will be less need for criminal investigators to shy away from FDP. Cold cases, missing persons, and victims in crimes without other evidence will one day soon all be well served by FDP.

  8. Forensic recovery within contaminated environment

    Williams, S.

    2002-01-01

    Full text: The Exhibit Handling System, operated by the Anti-Terrorist Branch, has evolved from experiences whilst dealing with long term domestic terrorism and the subsequent prosecution of the offenders. Stringent U.K. criminal law in regard to exhibits and forensic evidence required a strict system in order to provide continuity and integrity to every item that came into possession of the Police. This system also applies to items that are eventually deemed 'unused', as nearly all evidence is disclosed to the defence. I believe that if a system can withstand the close examination that British Criminal Law provides, it will probably be suitable in most countries. The system relies on each item being supplied with a documented trail of all persons who have had possession of it and who have opened the security packaging for examination purposes. In contaminated environments the initial process within the system has to be adapted in order that strict monitoring of the items can be carried out during the packaging process. It is also recognized that access to many exhibits will be heavily restricted and therefore protocols are in place to interrogate the evidence at the packaging stage in order to avoid unnecessary spread of contamination. The protocols are similar for both radiological and nuclear incidents as well as chemical and biological. Regardless of the type of incident the system can be adapted on the advice of the relevant scientific authority. In the U.K. for radiological and nuclear incidents that authority would be the A.W.E. Aldermaston. The integrity and continuity regime should be continued within laboratories which are conducting examinations of exhibits recovered. It is also important that Nuclear Forensic Laboratories do not overlook possibilities of traditional evidence, such as DNA, Fingerprints and fibre traces. Good record photography of items which are unlikely to be released by the laboratory is essential. Finally, cross-contamination has in

  9. Forensic Human Hair Examination and Comparison in the 21st Century.

    Houck, M M

    2005-01-01

    Forensic hair examination and comparison is often undervalued as evidence. Significant information can be developed from a thorough microscopic examination and comparison of human and animal hairs that can assist criminal and civil investigations. Animal hairs can be distinguished easily from human hairs and often can be specified to a genus, species, or even breed. Human hairs often can be identified as to their body area origin and the racial ancestry of the person from whom they originated. Additionally, damage, disease, or cosmetic treatments can be identified and described. Finally, suitable hairs can be compared microscopically with known hair samples to determine if they could have come from the same source. This application is now being augmented by mitochondrial DNA analysis, which enhances the information already available from a microscopic examination of evidentiary hairs. Training and qualification of forensic hair examiners is crucial to the quality and reliability of forensic hair examinations. Many of the weaknesses in forensic hair examinations seen to date are a result of inadequate training of forensic hair examiners and a lack of understanding about the fundamental nature of the examination of hairs. Mitochondrial DNA offers a chance for the rehabilitation and validation of microscopical examination of human, and potentially animal, hairs. Copyright © 2005 Central Police University.

    Nuclear forensics is the analysis of nuclear materials recovered from either the capture of unused materials, or from the radioactive debris following a nuclear explosion and can contribute significantly to the identification of the sources of the materials and the industrial processes used to obtain them. In the case of an explosion, nuclear forensics can also reconstruct key features of the nuclear device. Nuclear forensic analysis works best in conjunction with other law enforcement, radiological protection dosimetry, traditional forensics, and intelligence work to provide the basis for attributing the materials and/or nuclear device to its originators. Nuclear forensics is a piece of the overall attribution process, not a stand-alone activity

    The ability to accurately identify bird species is crucial for wildlife law enforcement and bird-strike investigations. However, such identifications may be challenging when only partial or damaged feathers are available for analysis. By applying vigorous contamination controls and sensitive PCR amplification protocols, we found that it was feasible to obtain accurate mitochondrial (mt)DNA-based species identification with as few as two feather barbs. This minimally destructive DNA approach was successfully used and tested on a variety of bird species, including North American wild turkey (Meleagris gallopavo), Canada goose (Branta canadensis), blue heron (Ardea herodias) and pygmy owl (Glaucidium californicum). The mtDNA was successfully obtained from 'fresh' feathers, historic museum specimens and archaeological samples, demonstrating the sensitivity and versatility of this technique. By applying appropriate contamination controls, sufficient quantities of mtDNA can be reliably recovered and analyzed from feather barbs. This previously overlooked substrate provides new opportunities for accurate DNA species identification when minimal feather samples are available for forensic analysis.

    2015-01-01

    Digital forensics and multimedia forensics are rapidly growing disciplines whereby electronic information is extracted and interpreted for use in a court of law. These two fields are finding increasing importance in law enforcement and the investigation of cybercrime as the ubiquity of personal computing and the internet becomes ever-more apparent. Digital forensics involves investigating computer systems and digital artefacts in general, while multimedia forensics is a sub-topic of digital forensics focusing on evidence extracted from both normal computer systems and special multimedia devices, such as digital cameras. This book focuses on the interface between digital forensics and multimedia forensics, bringing two closely related fields of forensic expertise together to identify and understand the current state-of-the-art in digital forensic investigation. Both fields are expertly attended to by contributions from researchers and forensic practitioners specializ ng in diverse topics such as forensic aut...

  17. An Improved Forensic Science Information Search.

    2015-01-01

    Although thousands of search engines and databases are available online, finding answers to specific forensic science questions can be a challenge even to experienced Internet users. Because there is no central repository for forensic science information, and because of the sheer number of disciplines under the forensic science umbrella, forensic scientists are often unable to locate material that is relevant to their needs. The author contends that using six publicly accessible search engines and databases can produce high-quality search results. The six resources are Google, PubMed, Google Scholar, Google Books, WorldCat, and the National Criminal Justice Reference Service. Carefully selected keywords and keyword combinations, designating a keyword phrase so that the search engine will search on the phrase and not individual keywords, and prompting search engines to retrieve PDF files are among the techniques discussed.

    From 1997 to 2002 the United Nations International Criminal Tribune for the former Yugoslavia (ICTY) undertook the exhumation of mass graves in NE Bosnia as part of the war crimes investigations aimed at providing evidence for the prosecution of war criminals in The Hague. This involved the location and exhumation of seven former mass graves (primary sites) dug following the fall of Srebrenica in July 1995. These primary mass graves were secretly and hurriedly exhumed three months later and most of the bodies or body parts transported and reburied in a large number of secondary sites many of which were subsequently exhumed by ICTY. The aim of the pollen and soil/sediment studies was to provide an 'environmental profile' of the original site of the samples and use this to match the relocated bodies to the original mass graves. This was part of completing the chain of evidence, providing evidence of the scale and organization of the original atrocities and the subsequent attempts to conceal the evidence related to them. All the primary sites were located in areas of contrasting geology, soils and vegetation, and this allowed matching of the sediment transported in intimate contact with the bodies to the original burial sites, which in some cases were also the execution sites. In all, over 24 sites were investigated, over 240 samples collected and analyzed under low power microscopy and 65 pollen sub-samples fully analyzed. The pollen and sediment descriptions were used in conjunction with the mineralogy (using XRD) of primary and secondary sites in order to provide matches. These matches were then compared with matching evidence from ballistic studies and clothing. The evidence has been used in court and is now in the public domain. It is believed this is the first time 'environmental profiling' techniques have been used in a systematic manner in a war crimes investigation.

    Cisco IOS (the software that runs the vast majority of Cisco routers and all Cisco network switches) is the dominant routing platform on the Internet and corporate networks. This widespread distribution, as well as its architectural deficiencies, makes it a valuable target for hackers looking to attack a corporate or private network infrastructure. Compromised devices can disrupt stability, introduce malicious modification, and endanger all communication on the network. For security of the network and investigation of attacks, in-depth analysis and diagnostics are critical, but no book current

    2014-03-01

    In this paper the insights and results are presented of a long term and ongoing improvement effort within the Netherlands Forensic Institute (NFI) to establish a valuable innovation programme. From the overall perspective of the role and use of forensic science in the criminal justice system, the concepts of Forensic Information Value Added (FIVA) and Forensic Information Value Efficiency (FIVE) are introduced. From these concepts the key factors determining the added value of forensic investigations are discussed; Evidential Value, Relevance, Quality, Speed and Cost. By unravelling the added value of forensic science and combining this with the future needs and scientific and technological developments, six forensic grand challenges are introduced: i) Molecular Photo-fitting; ii) chemical imaging, profiling and age estimation of finger marks; iii) Advancing Forensic Medicine; iv) Objective Forensic Evaluation; v) the Digital Forensic Service Centre and vi) Real time In-Situ Chemical Identification. Finally, models for forensic innovation are presented that could lead to major international breakthroughs on all these six themes within a five year time span. This could cause a step change in the added value of forensic science and would make forensic investigative methods even more valuable than they already are today. © 2013.

    The bodies of socially isolated people may remain undiscovered in their own houses for prolonged periods. Occasionally the body is in situ for sufficient time to become skeletonised, or partially so. Medico-legal investigation of these cases is complicated by degradation and contamination of evidence. Thus, a multidisciplinary forensic investigation is recommended. The potential contributions of forensic pathology, anthropology, odontology and entomology are outlined here with reference to two cases that occurred in Victoria, Australia, in 2003. Forensic pathologists are often unable to determine the cause of death in skeletonised bodies, however, they may find evidence to support either a natural or unnatural mode of death, and they may describe skeletal pathology or trauma, and identify skeletal features to support radiological identification of the deceased. Anthropologists can provide supplementary evidence of skeletal trauma. Additionally, they can assess age, sex, stature and racial affiliation from skeletal remains. Odontologists can identify individuals through comparison with ante-mortem dental records; however, potential difficulties exist in identifying the treating dentist of a socially isolated person. Odontologists may also examine the teeth and oro-facial skeleton for trauma. Entomologists may estimate minimum death time and/or season of death. Entomological examination of insect remains may also confirm that a body has lain in situ for a considerable period.

  4. Investigation of effective forensic cleaning methods for bullet and cartridge case samples

    Science.gov (United States)

    Shuherk, Cassie Marie

    Bullet and cartridge case evidence may potentially link weapons and crimes through the comparison of toolmark patterns. This analysis relies on the clarity of the toolmarks and the ability of the examiner to identify patterns on the evidence. These patterns may be distorted by debris such as soil, blood, cyanoacrylate, and construction materials. Despite the potential importance of bullet and cartridge case evidence, few investigations of proper cleaning methods have been conducted. The present study was designed to examine the effects of various cleaning solutions and application methods on copper and brass bullets and cartridge cases. Additionally, this research investigated the efficacy of these cleaning protocols on the common evidence contaminants blood and cyanoacrylate. No cleaning method was found to be universally effective on both contaminant types and nondestructive to the metal surface. Ultrasonication was the most efficient application method employed when used in conjunction with an appropriate cleaning solution. Acetone proved to be safe and successful at removing heavy cyanoacrylate deposits from brass cartridge cases without damaging the metal. Although sulfuric acid removed most of the cyanoacrylate from the brass cartridge case, ultrasonication of the fumed cartridge cases in sulfuric acid caused the nickel-plated primer caps to turn black. Additionally, etching occurred when sulfuric acid was allowed to dry on the cartridge case surface. Citric acid, salt-flour-vinegar paste, TergazymeRTM, and water did not effectively remove the cyanoacrylate from the cartridge cases, but the solutions were safe to use on the brass and sometimes resulted in a shinier surface. Regardless of the cleaning method employed, the bloodstained bullets retained most or all of the underlying brown tarnish. Ultrasonication with sulfuric acid was successful at removing some blood-initiated tarnishing; however, the removal of residues was not complete, making it difficult

    In a country notorious for violent crime, it seems that South African medico-legal laboratories make minimal application of technology in the death investigation process and little attention is given to trace evidence. Non-destructive, non-invasive, portable and cost-effective tools are required. This study was conducted at the Pretoria Medico-Legal Laboratory. The surface area of the bodies and clothing of victims of fatal interpersonal violence were examined using a torch, magnifying lamp, portable digital microscope and alternate light source to gauge their potential for trace evidence detection. Most studies apply these and similar tools to inert surfaces, with few focusing on their application to human skin. There was a statistically significant difference in the detection of many of the evidence types between the naked-eye observation of the pathologists and the technologies. The different imaging technologies were compared as to their cost, evidence detection ability and ease of use. The most common evidence types discovered on the bodies and clothing of victims of fatal interpersonal violence, as well as the propensity of each tool to detect these, was evaluated in order to devise the best option for incorporation into the Pretoria Medico-Legal Laboratory routine. The digital microscope performed best overall followed by the magnifying lamp, torch and the Polilight(®). This study aimed to justify the investment of more time, effort and funding into trace evidence recovery in the South African mortuary environment. Copyright © 2015 Elsevier Ireland Ltd.

    Full Text Available Since the reformation and democratization movement in 1998, Indonesians have faced a chronic corruption problem. At the beginning of reformation era in 1998 to fight against corruption, the Indonesian government reforms the organization structure of the Indonesia Police to be an independent body separated from the Military organization. The police reforms begun in 1999 and got legal foundation with Act No. 2/2002. However, since fourteen years, the level of police reform has not yet succeed because of low community satisfaction on police service and the intense conflicts always occur whenever ACA investigates the case of corruptions conducted by police leaders. Three conflicts between police institution and ACA have taken placed. By using institutionalism approach, this research focus on the reform in police themselves are major actors on how reforms are organized and managed. This study is interpretative in nature gained only through social constructions such as language, consciousness, shared meanings, documents, tools, and other artefacts’. This finding revealed that this unsuccessful institutionalization process took place in a context of the main task of police for communicty service. Second, the study has demonstrated that three concepts from institutional theory as aforementioned provided vocabularies and insights to explain the phenomenon under study.

  7. An introduction to computer forensics.

    2006-07-01

    This paper provides an introduction to the discipline of Computer Forensics. With computers being involved in an increasing number, and type, of crimes the trace data left on electronic media can play a vital part in the legal process. To ensure acceptance by the courts, accepted processes and procedures have to be adopted and demonstrated which are not dissimilar to the issues surrounding traditional forensic investigations. This paper provides a straightforward overview of the three steps involved in the examination of digital media: Acquisition of data. Investigation of evidence. Reporting and presentation of evidence. Although many of the traditional readers of Medicine, Science and the Law are those involved in the biological aspects of forensics, I believe that both disciplines can learn from each other, with electronic evidence being more readily sought and considered by the legal community and the long, tried and tested scientific methods of the forensic community being shared and adopted by the computer forensic world.

    Guanaco (Lama guanicoe) is a protected and widely distributed ungulate in South America. A poacher, after killing guanacos in Valle Chacabuco, Chilean Patagonia, transported and stored the meat. Samples were retrieved by local police but the suspect argued that the meat was from a horse. Mitochondrial cytochrome b gene (774 pb), 15 loci microsatellites, and SRY gene were used to identify the species, number of animals and their population origin, and the sex of the animals, respectively. Analysis revealed that the samples came from a female (absence of SRY gene) Patagonian guanaco (assignment probability between 0.0075 and 0.0282), and clearly distinguishing it from sympatric ungulates (E-value = 0). Based on the evidence obtained in the field in addition to forensic data, the suspect was convicted of poaching and illegally carrying fire arms. This is the first report of molecular tools being used in forensic investigations of Chilean wildlife indicating its promising future application in guanaco management and conservation.

The characteristics, such as, dimensions, particle size, elemental and isotopic composition help the nuclear forensic analyst in source attribution of the interdicted material, as the specifications of the nuclear materials used by different countries are different. The analysis of elemental composition could be done by SEM-EDS, XRF, CHNS analyser, etc. depending upon the type of the material. Often the trace constituents (analysed by ICP-AES, ICP-MS, AAS, etc) provide valuable information about the processes followed during the production of the material. Likewise the isotopic composition determined by thermal ionization mass spectrometry provides useful information about the enrichment of the nuclear fuel and hence its intended use

    2016-09-01

    Veterinary forensic pathology is emerging as a distinct discipline, and this special issue is a major step forward in establishing the scientific basis of the discipline. A forensic necropsy uses the same skill set needed for investigations of natural disease, but the analytical framework and purpose of forensic pathology differ significantly. The requirement of legal credibility and all that it entails distinguishes the forensic from routine diagnostic cases. Despite the extraordinary depth and breadth of knowledge afforded by their training, almost 75% of veterinary pathologists report that their training has not adequately prepared them to handle forensic cases. Many veterinary pathologists, however, are interested and willing to develop expertise in the discipline. Lessons learned from tragic examples of wrongful convictions in medical forensic pathology indicate that a solid foundation for the evolving discipline of veterinary forensic pathology requires a commitment to education, training, and certification. The overarching theme of this issue is that the forensic necropsy is just one aspect in the investigation of a case of suspected animal abuse or neglect. As veterinary pathologists, we must be aware of the roles filled by other veterinary forensic experts involved in these cases and how our findings are an integral part of an investigation. We hope that the outcome of this special issue of the journal is that veterinary pathologists begin to familiarize themselves with not only forensic pathology but also all aspects of veterinary forensic science. © The Author(s) 2016.

    In Finland, forensic age assessment is strictly regulated by legislation. According to the Aliens Act (301/2004) and the amendment of the Act (549/2010), the police authorities, the frontier guard authorities, and the immigration authorities have the right to refer asylum seekers to the University of Helsinki, Department of Forensic Medicine, for age assessment. These assessments are especially performed to solve if the person is of major age, the cutoff being 18 completed years. The forensic age assessment is largely based on dental development, since the special permit of the Radiation and Nuclear Safety Authority (STUK) to the Department of Forensic Medicine of the University of Helsinki, allowing the use of ionizing radiation for non-medical purposes, includes dental and hand X-rays. Forensic age assessment is always performed by two forensic odontologists. In 2015, the total number of forensic age assessment examinations was 149, and the countries of origin of the asylum seekers were most commonly Iraq, Afghanistan, and Somalia. The current legislation on forensic age assessment has been well received and approved. Radiological and other examinations can be performed in different parts of Finland, but the forensic odontologist at the University of Helsinki is always involved in the process and ensures joint quality standards for the forensic age assessment.

    Full Text Available Computer Crime and computer related incidents continue their prevalence and frequency and result in loss of billions of dollars. To fight against those crimes and frauds, it is urgent to develop digital forensics education programs to train a suitable workforce to efficiently and effectively investigate crimes and frauds. However, there is no standard to guide the design of digital forensics curriculum for an academic program. In this research, we investigate the research works on digital forensics curriculum design and existing education programs.  Both digital forensics educators and practitioners were surveyed and the results are analyzed to determine what industry and law enforcement need. Based on the survey results and what the industry certificate programs cover, we identified topics that are desired to be covered in digital forensics courses. Finally, we propose six digital forensics courses and their topics that can be offered in both undergraduate and graduate digital forensics programs.

    The illegal use of formalin (commercial formaldehyde) in cosmetic products harms the health of individuals exposed to this substance. Over the last years, the commercial availability of these products, especially those containing irregular dosage of formaldehyde, has increased in Brazil. This work analyzes some products for hair treatment available in the Brazilian market and verifies their safety. The adopted analytical methodology involved sample derivatization with 2,4-dinitrophenylhydrazine, followed by high-performance liquid chromatography with ultraviolet detection (UV-VIS) at λ = 365 nm. The limit of quantification is 2.5 × 10 -3% w/w, and the recovery tests were around 93%. Some of the samples contained high and illegal formaldehyde levels ranging from 9% to 19% (w/w) and others presented suitable concentrations of the analyte. On the basis of the results, this work discusses the efficiency and practicality of this analytical method for forensic purposes. © 2016 American Academy of Forensic Sciences.

  5. Seeking to understand lived experiences of personal recovery in personality disorder in community and forensic settings - a qualitative methods investigation.

    Shepherd, Andrew; Sanders, Caroline; Shaw, Jenny

    2017-08-01

    Understandings of personal recovery have emerged as an alternative framework to traditional ideas of clinical progression, or symptom remission, in clinical practice. Most research in this field has focussed on the experience of individuals suffering with psychotic disorders and little research has been conducted to explore the experience of individuals with a personality disorder diagnosis, despite the high prevalence of such difficulties. The nature of the personality disorder diagnosis, together with high prevalence rates in forensic settings, renders the understanding of recovery in these contexts particularly problematic. The current study seeks to map out pertinent themes relating to the recovery process in personality disorder as described by individuals accessing care in either community or forensic settings. Individual qualitative interviews were utilised to explore the lived experience of those receiving a personality disorder diagnosis and accessing mental health care in either community or forensic settings. A thematic analysis was conducted to identify shared concepts and understanding between participants. Fourty-one individual participant interviews were conducted across forensic and community settings. Recovery was presented by participants as a developing negotiated understanding of the self, together with looked for change and hope in the future. Four specific themes emerged in relation to this process: 1. Understanding early lived experience as informing sense of self 2. Developing emotional control 3.

    Since 1994 the Institute for Transuranium Elements has played the leading role in Europe in the development of Nuclear Forensic Science. This is a new discipline which has developed out of necessity following the break up of the former Soviet Union and Eastern Block countries in 1989, which resulted in the emergence of a new form of illegal smuggling - that of nuclear materials. The Institute has been involved in the investigation of all the major cases of illicit trafficking involving nuclear- and nuclear-related materials in Europe from 1994, following the first major incident at Munich airport, up to the present time. Examples will be given here illustrating different types of cases: the accidental release of nuclear material into the environment, exercises carried out in cooperation with the German Federal Police (Bundeskriminalamt), and the removal of nuclear material with deliberate criminal intent

    Odour of the animal or human corpses immediately after death is very attractive for insects and other invertebrates. Blue and green bottle flies from the Calliphoridae family are the first colonizers of cadaver and immediately later necrophagous Diptera from the Sarcophagidae family settle on the same corpse. It is essential to determine the time past after death for elucidating the event in case of the homicide or suspicious death, and it is directly proportional to the post mortem interval expected time, which is based upon the speed of the larval growth. In this article, we purposed to stress the special interest of forensic entomology for the scientists who will apply this science in their forensic researches and case studies, and also to provide information to our judges, prosecutors and law enforcement agents in order to consider the entomological samples to be reliable and applicable evidences as biological stains and hairs. We are of the opinion that if any forensic entomologist is called to the crime scene or if the evidences are collected and then delivered to an entomologist, the forensic cases will be elucidated faster and more accurately.

    This research project was performed to assist the Faculty of Forensic and Legal Medicine (FFLM) with the development of a training programme for Principal Forensic Physicians (PFPs) (Since this research was performed the Metropolitan Police Service have dispensed with the services of the Principal Forensic Physicians so currently (as of January 2009) there is no supervision of newly appointed FMEs or the development training of doctors working in London nor any audit or appraisal reviews.) to fulfil their role as educational supervisors. PFPs working in London were surveyed by questionnaire to identify the extent of their knowledge with regard to their role in the development training of all forensic physicians (FPs) in their group, the induction of assistant FPs and their perceptions of their own training needs with regard to their educational role. A focus group was held at the FFLM annual conference to discuss areas of interest that arose from the preliminary results of the questionnaire. There is a clear need for the FFLM to set up a training programme for educational supervisors in clinical forensic medicine, especially with regard to appraisal. 2009 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

    Over the past six years the Brazilian Federal Police has undertaken major efforts in order to implement and to develop its own drug chemical profiling program. This paper aims to provide a broad perspective regarding the managerial strategies and some examples of subsequent technical issues involved in the implementation of such a project. Close collaboration with local drug enforcement and investigation teams, establishment of proper worldwide partnerships with well recognized institutions in the field of drug analysis and the attainment of suitable funding and human resources are shown to be key success factors. Some preliminary results concerning the chemical profile of cocaine seizures in Brazil during this process are presented. Copyright © 2014 Forensic Science Society. Published by Elsevier Ireland Ltd.

    2017-01-01

    This paper describes mental health related stigma expressed by police to police using a newly developed 11-item Police Officer Stigma Scale and reports on the preliminary psychometric properties (factor structure and internal reliability) of this scale. The scale used an indirect measurement approach adapted from the Perceived Devaluation and Discrimination Scale. Five themes appropriate to police culture were adapted and six additional items were added. Responses were rated on a 5-point agreement scale with an additional don't know option. Data were collected from officers attending a mandatory workshop (90.5% response). Exploratory factor analysis showed the scale to be unidimensional and internally reliable (Cronbach's alpha was 0.82). The most endorsed items pertained to avoiding disclosure to a supervisor/manager or to a colleague (85% agreement), that most officers would expect discrimination at work (62%), and that most officers would not want a supervisor or manager who had a mental illness (62%). Findings highlight that (a) Police-to-police mental illness stigma may be a particularly strong feature of police cultures; (b) police should be a focus for targeted anti-stigma interventions; and (c) though further psychometric testing is needed, the Police Office Stigma Scale may provide important insights into the nature and functioning of police-to-police stigma in police cultures in future research.

    The aim of the investigation is to define as clearly as possible specific forensic psychiatric characteristics of persons who committed homicide and or attempted due to jealousy (the nature and severity of psychopathology, the level of responsibility, danger for the community, intensity and nature of aggression, the victimologic dimension, the relation of alcohol and jealousy). A retrospective method based on forensic psychiatric expertises in the period 1975-1999 was used. They encompassed 200 examinees that committed murder or attempted it. The results show the connection of psychotic jealousy with the highest degree of danger in diagnostic categories of paranoid psychosis and paranoid schizophrenia. The time span from the first manifestations of jealousy until the actual commitment of a crime is the longest in personality disorders and the shortest in schizophrenia. Exogenous provoking situations were dominant for committing homicide due to jealousy in personality disorders. Acute alcohol intoxication has a specific significance in crime due to jealousy in the same diagnostic category. Clear criteria were designed for forensic psychiatric evaluation of murder and attempts of homicide caused by jealousy, which will be of help in everyday practice in the field forensic work and treatment.

    Studying links between triacetone triperoxide (TATP) samples from crime scenes and suspects can assist in criminal investigations. Isotope ratio mass spectrometry (IRMS) and gas chromatography (GC)-IRMS were used to measure the isotopic compositions of TATP and its precursors acetone and hydrogen peroxide. In total, 31 TATP samples were synthesized with different raw material combinations and reaction conditions. For carbon, a good differentiation and a linear relationship were observed for acetone-TATP combinations. The extent of negative (δ(13) C) fractionation depended on the reaction yield. Limited enrichment was observed for the hydrogen isotope (δ(2) H) values of the TATP samples probably due to a constant exchange of hydrogen atoms in aqueous solution. For oxygen (δ(18) O), the small isotopic range and excess of water in hydrogen peroxide resulted in poor differentiation. GC-IRMS and IRMS data were comparable except for one TATP sample prepared with high acid concentration demonstrating the potential of compound-specific isotope analysis. Carbon IRMS has practical use in forensic TATP investigations. © 2016 American Academy of Forensic Sciences.

    2008-01-01

    Environmental forensic microscopy investigations are based on the methods and procedures developed in the fields of criminal forensics, industrial hygiene and environmental monitoring. Using a variety of microscopes and techniques, the environmental forensic scientist attempts to reconstruct the sources and the extent of exposure based on the physical evidence left behind after particles are exchanged between an individual and the environments he or she passes through. This article describes how environmental forensic microscopy uses procedures developed for environmental monitoring, criminal forensics and industrial hygiene investigations. It provides key references to the interdisciplinary approach used in microscopic investigations. Case studies dealing with lead, asbestos, glass fibers and other particulate contaminants are used to illustrate how environmental forensic microscopy can be very useful in the initial stages of a variety of environmental exposure characterization efforts to eliminate some agents of concern and to narrow the field of possible sources of exposure.

    Forensic anthropology is the application of biological or physical anthropology in the service of justice. One main area is the analysis of human remains. Such analyses involve person identification by assessment of age and sex of the deceased, and comparison with ante-mortem data. Another major area is the analysis of surveillance pictures and videos. Such analyses may comprise facial and bodily morphological comparisons, multi-angle photogrammetry and gait analysis. We also perform studies of human remains for archaeologists.

    Lead is contained as trace element in uranium ores and propagates throughout the production process to intermediate products like yellow cake or uranium oxide. The lead isotopes in such material originate from two sources: natural lead and radiogenic lead. The variability of the isotopic composition of lead in ores and yellow cakes was studied and the applicability of this parameter for nuclear forensic investigations was investigated. Furthermore, the chemical impurities contained in these materials were measured in order to identify characteristic differences between materials from different mines. For the samples investigated, it could be shown, that the lead isotopic composition varies largely from mine to mine and it may be used as one of the parameters to distinguish between materials of different origins. Some of the chemical impurities show a similar pattern and support the conclusions drawn from the lead isotope data. (orig.)

  4. Likelihood ratio and posterior odds in forensic genetics: Two sides of the same coin.

    2017-05-01

    It has become widely accepted in forensics that, owing to a lack of sensible priors, the evidential value of matching DNA profiles in trace donor identification or kinship analysis is most sensibly communicated in the form of a likelihood ratio (LR). This restraint does not abate the fact that the posterior odds (PO) would be the preferred basis for returning a verdict. A completely different situation holds for Forensic DNA Phenotyping (FDP), which is aimed at predicting externally visible characteristics (EVCs) of a trace donor from DNA left behind at the crime scene. FDP is intended to provide leads to the police investigation helping them to find unknown trace donors that are unidentifiable by DNA profiling. The statistical models underlying FDP typically yield posterior odds (PO) for an individual possessing a certain EVC. This apparent discrepancy has led to confusion as to when LR or PO is the appropriate outcome of forensic DNA analysis to be communicated to the investigating authorities. We thus set out to clarify the distinction between LR and PO in the context of forensic DNA profiling and FDP from a statistical point of view. In so doing, we also addressed the influence of population affiliation on LR and PO. In contrast to the well-known population dependency of the LR in DNA profiling, the PO as obtained in FDP may be widely population-independent. The actual degree of independence, however, is a matter of (i) how much of the causality of the respective EVC is captured by the genetic markers used for FDP and (ii) by the extent to which non-genetic such as environmental causal factors of the same EVC are distributed equally throughout populations. The fact that an LR should be communicated in cases of DNA profiling whereas the PO are suitable for FDP does not conflict with theory, but rather reflects the immanent differences between these two forensic applications of DNA information.

    2014-01-01

    Full Text Available The task of this study was to investigate the level of satisfaction of various categories of crime victims with various aspects of police work and behavior. The aim of this research was to examine whether the police treat all victims of crime equally responsibly, or whether there is a significant difference in the satisfaction of various categories of crime victims with various aspects of police work and behavior. On an occasional sample of 150 examinees, we analyzed the level of satisfaction of crime victims in relation to the expectations of the police regarding the reported criminal offenses and then the level of satisfaction towards different aspects of work and conduct of the police, such as reporting crime to the police, environmental conditions of interview and human compassion/empathy of police officers. The results indicate a significant difference in the satisfaction of specified aspects of police work among different categories of victims. Most dissatisfaction was expressed by members of the LGBT community and convicted persons when they appear in the role of victims. The research makes recommendations for improving the quality of the work and behavior of the police towards victims of crime.

    2013-12-01

    The increasing use of near-surface geophysical methods in forensic searches has demonstrated the need for further studies to identify the ideal physical, environmental and temporal settings for each geophysical method. Previous studies using resistivity methods have shown promising results, but additional work is required to more accurately interpret and analyze survey findings. The Ontario Provincial Police's UCRT (Urban Search and Rescue; Chemical, Biolgical, Radiological, Nuclear and Explosives; Response Team) is collaborating with the University of Toronto and two additional universities in a multi-year study investigating the applications of near-surface geophysical methods to terrestrial forensic searches. In the summer of 2012, on a test site near Bolton, Ontario, the OPP buried weapons, drums and pigs (naked, tarped, and clothed) to simulate clandestine graves and caches. Our study aims to conduct repeat surveys using an IRIS Syscal Junior with 48 electrode switching system resistivity-meter. These surveys will monitor changes in resistivity reflecting decomposition of the object since burial, and identify the strengths and weaknesses of resistivity when used in a rural, clandestine burial setting. Our initial findings indicate the usefulness of this method, as prominent resistivity changes have been observed. We anticipate our results will help to assist law enforcement agencies in determining the type of resistivity results to expect based on time since burial, depth of burial and state of dress of the body.

  14. Extracting ballistic forensic intelligence: microstamped firearms deliver data for illegal firearm traffic mapping: technology, implementation, and applications

    Science.gov (United States)

    Ohar, Orest P.; Lizotte, Todd E.

    2009-08-01

    Over the years law enforcement has become increasingly complex, driving a need for a better level of organization of knowledge within policing. The use of COMPSTAT or other Geospatial Information Systems (GIS) for crime mapping and analysis has provided opportunities for careful analysis of crime trends. By identifying hotspots within communities, data collected and entered into these systems can be analyzed to determine how, when and where law enforcement assets can be deployed efficiently. This paper will introduce in detail, a powerful new law enforcement and forensic investigative technology called Intentional Firearm Microstamping (IFM). Once embedded and deployed into firearms, IFM will provide data for identifying and tracking the sources of illegally trafficked firearms within the borders of the United States and across the border with Mexico. Intentional Firearm Microstamping is a micro code technology that leverages a laser based micromachining process to form optimally located, microscopic "intentional structures and marks" on components within a firearm. Thus when the firearm is fired, these IFM structures transfer an identifying tracking code onto the expended cartridge that is ejected from the firearm. Intentional Firearm Microstamped structures are laser micromachined alpha numeric and encoded geometric tracking numbers, linked to the serial number of the firearm. IFM codes can be extracted quickly and used without the need to recover the firearm. Furthermore, through the process of extraction, IFM codes can be quantitatively verified to a higher level of certainty as compared to traditional forensic matching techniques. IFM provides critical intelligence capable of identifying straw purchasers, trafficking routes and networks across state borders and can be used on firearms illegally exported across international borders. This paper will outline IFM applications for supporting intelligence led policing initiatives, IFM implementation strategies

  15. A history of forensic anthropology.

    2018-04-01

    Forensic anthropology represents a dynamic and rapidly evolving complex discipline within anthropology and forensic science. Academic roots extend back to early European anatomists but development coalesced in the Americas through high-profile court testimony, assemblage of documented collections and focused research. Formation of the anthropology section of the American Academy of Forensic Sciences in 1972, the American Board of Forensic Anthropology in 1977/1978 and other organizational advances provided important stimuli for progress. While early pioneers concentrated on analysis of skeletonized human remains, applications today have expanded to include complex methods of search and recovery, the biomechanics of trauma interpretation, isotopic analysis related to diet and region of origin, age estimation of the living and issues related to humanitarian and human rights investigations. © 2018 Wiley Periodicals, Inc.

  16. Multimedia Forensics Is Not Computer Forensics

    Science.gov (United States)

    Böhme, Rainer; Freiling, Felix C.; Gloe, Thomas; Kirchner, Matthias

    The recent popularity of research on topics of multimedia forensics justifies reflections on the definition of the field. This paper devises an ontology that structures forensic disciplines by their primary domain of evidence. In this sense, both multimedia forensics and computer forensics belong to the class of digital forensics, but they differ notably in the underlying observer model that defines the forensic investigator’s view on (parts of) reality, which itself is not fully cognizable. Important consequences on the reliability of probative facts emerge with regard to available counter-forensic techniques: while perfect concealment of traces is possible for computer forensics, this level of certainty cannot be expected for manipulations of sensor data. We cite concrete examples and refer to established techniques to support our arguments.

    Nambiar, P; Bridges, T E; Brown, K A

    1991-06-01

    As a result of a systematic morphometric study of shark dentitions, a system of notation for describing the location of shark teeth has been developed and is proposed as a standard to be adopted for use in similar studies in the future. The macroscopic morphology of White Shark teeth has been characterised in order to gain quantitative data which might assist in identification of these sharks from bite marks on victims or objects or from shark carcasses. Using these data, a nomogram has been developed which can be used to estimate the body length of a White Shark from measurements of tooth or bite mark morphology. An example of the forensic application of such allometric data is provided as it applied to a recent fatal attack on a diver by a White Shark.

    Detection on automated DNA sequencers of polymerase chain reaction (PCR) products of tetra- and penta-nucleotide short tandem repeat (STR) loci frequently reveals one or more extra peaks along with the true, major allele peak. The most frequent extra peak pattern is a single smaller peak which...... is one repeat unit shorter than the true allele peak. The existence of such artificial peaks is of special importance when the methods are used for forensic investigations because the artificial extra peaks may simulate true alleles when samples containing mixtures of DNA from different individuals...... are analyzed. We have investigated the relative levels of formation of extra peaks in 14 STR marker systems. We found that not only the parameters of the PCR but also factors determining the stringency during the post-PCR and pre-electrophoresis handling of samples were of importance for the formation of extra...

    The National Forensic Service (NFS) of Korea is a government agency responsible for examining and evaluating evidence obtained at crime scenes. The Section of Forensic Odontology of the Medical Examiner's Office conducts forensic odontological analyses of human remains, and mainly criminal cases are handled. In this study, 588 forensic odontological cases referred to NFS during 2011-2015 were analyzed for referral pattern, evidence material, examination criteria, and other factors and were compared with respective data from 2007 to 2010. Majority of the requests were internal (further dental examinations after autopsy) rather than external (direct requests from other agencies such as police departments). Regarding evidence materials, "Teeth" (including teeth and resected jaws) were dominant evidences. Due to the seasonal effects in Korea, the highest number of requests was in September of each year, but the number of requests in April has recently increased. Evidence materials were mostly found in suburban and rural area, especially in mountainous area due to the geographic characteristics of Korea. Regarding specific examinations, profiling, including age estimation, accounted for majority of the requests; this number had increased relative to the findings of a previous study, whereas the number of requests for dental identification and bite mark analysis had decreased. With this analysis, trends in forensic odontology can be observed, and we expect that these trends would be served as a reference for designing study and making training protocol for forensic odontology.

    Dror, Itiel E.

    2015-01-01

    The human element plays a critical role in forensic science. It is not limited only to issues relating to forensic decision-making, such as bias, but also relates to most aspects of forensic work (some of which even take place before a crime is ever committed or long after the verification of the forensic conclusion). In this paper, I explicate many aspects of forensic work that involve the human element and therefore show the relevance (and potential contribution) of cognitive neuroscience to forensic science. The 10 aspects covered in this paper are proactive forensic science, selection during recruitment, training, crime scene investigation, forensic decision-making, verification and conflict resolution, reporting, the role of the forensic examiner, presentation in court and judicial decisions. As the forensic community is taking on the challenges introduced by the realization that the human element is critical for forensic work, new opportunities emerge that allow for considerable improvement and enhancement of the forensic science endeavour.

  9. Understanding Nuclear Forensics in 5 Questions

    International Nuclear Information System (INIS)

    2014-01-01

    Forensic science, commonly referred to as forensics, is the examination of physical, biological, behavioural and documentary evidence. The goal of forensics is to discover linkages among people, places, things and events. A sub-discipline of forensic science, nuclear forensics is the analysis of intercepted illicit nuclear or radioactive material and any associated material, which can assist in law enforcement investigations as well as assessments of the potential vulnerabilities associated with the use, production and storage of these materials as part of a nuclear security infrastructure. The analysis of nuclear or other radioactive material seeks to identify what the materials are, how, when, and where the materials were made, and what their intended uses were. Nuclear forensics is an important tool in the fight against illicit trafficking in nuclear and radiological material

    2017-03-01

    An Android social app taxonomy incorporating artifacts that are of forensic interest will enable users and forensic investigators to identify the personally identifiable information (PII) stored by the apps. In this study, 30 popular Android social apps were examined. Artifacts of forensic interest (e.g., contacts lists, chronology of messages, and timestamp of an added contact) were recovered. In addition, images were located, and Facebook token strings used to tie account identities and gain access to information entered into Facebook by a user were identified. Based on the findings, a two-dimensional taxonomy of the forensic artifacts of the social apps is proposed. A comparative summary of existing forensic taxonomies of different categories of Android apps, designed to facilitate timely collection and analysis of evidentiary materials from Android devices, is presented. © 2016 American Academy of Forensic Sciences.

  11. Women in International Policing: Replacing an “Old Boys Club”?

    Directory of Open Access Journals (Sweden)

    Saskia Hufnagel

    2018-03-01

    Full Text Available Globalisation has increased the importance of international police cooperation. While cross-border law enforcement can be traced back as far as the Nineteenth Century, police cooperation today—such as Joint Investigation Teams, International Liaison Officers, and Interpol—only came about in the Twentieth Century. It was developed to counter transnational organised crime, such as drug crime and immigration crime, as well as terrorism. But, another aspect of international policing is that of peacekeeping; that is, the deployment of national police to countries during or after conflict to maintain law and order where the local police do not have sufficient capacities. This paper examines how women have been elevated in this police cooperation role, particularly Interpol and international peacekeeping. The discussion focuses on whether there are indications that internationally related tasks and agencies provide a more accepting environment for female police officers as opposed to a national police force setting.

    Brown, Katherine M; Keppel, Robert D

    2012-03-01

    This study examined 733 child abduction murders (CAMs) occurring from 1968 to 2002 to explore the influence of forensic evidence on case solvability in CAM investigations. It was hypothesized that the presence of forensic evidence connecting the offender to the crime would enhance case solvability in murder investigations of abducted children. This study examined the impact of CAM of different types of forensic evidence and the impact of the summed total of forensic evidence items on case solvability by controlling for victim age, victim race, victim gender, and victim-offender relationship. Time and distance theoretical predictors were also included. Binomial logistic regression models were used to determine whether forensic evidence was a critical solvability factor in murder investigations of abducted children. This research indicated that, while forensic evidence increased case solvability, the impact of forensic evidence on solvability was not as important as other solvability factors examined. © 2011 American Academy of Forensic Sciences.

    On February 8th 1988, a two-motor passenger aircraft of Metroliner type with 21 people on board entered a front of heavy weather at an altitude of 900 m and crashed after being struck by lightning which led to complete breakdown of the electrical systems on board. The site of the crash was in the marshy Ruhr meadows. The formation of the terrain enabled a subdivision into plan squares for rescue. The identification of the 21 bodies was carried out in the Essen Institute of Forensic Medicine in collaboration with the identification commission of the Federal Criminal Investigation Office. The experience and recommendations for future (possibly larger-scale) disasters derived from this are described. Furthermore, the accident pattern in the casualties typical for this air crash is discussed.

    Aydogdu, Eyup

    Thanks to the rapid developments in science and technology in recent decades, especially in the past two decades, forensic sciences have been making invaluable contributions to criminal justice systems. With scientific evaluation of physical evidence, policing has become more effective in fighting crime and criminals. On the other hand, law enforcement personnel have made mistakes during the detection, protection, collection, and evaluation of physical evidence. Law enforcement personnel, especially patrol officers, have been criticized for ignoring or overlooking physical evidence at crime scenes. This study, conducted in a large American police department, was aimed to determine the perceptions of patrol officers, their supervisors and administrators, detectives, and crime scene technicians about the forensic science needs of patrol officers. The results showed no statistically significant difference among the perceptions of the said groups. More than half of the respondents perceived that 14 out of 16 areas of knowledge were important for patrol officers to have: crime scene documentation, evidence collection, interviewing techniques, firearm evidence, latent and fingerprint evidence, blood evidence, death investigation information, DNA evidence, document evidence, electronically recorded evidence, trace evidence, biological fluid evidence, arson and explosive evidence, and impression evidence. Less than half of the respondents perceived forensic entomology and plant evidence as important for patrol officers.

    The police are the frontline workers in crisis situations involving patients with severe mental illness and act as a primary referral source for psychiatric emergency services (PES) in the community. The aims of this study were to investigate the distribution and characteristics of police referral among psychiatric patients in Taiwan. The study cohort consisted of patients who visited the PES of Taipei City Psychiatric Center from January 2009 to December 2010. The associations between the factors of demographics, clinical characteristics, and psychiatric service utilization and police referral were evaluated. Among the 7656 psychiatric emergency visits, 3029 (39.6%) were referred by the police. These patients referred by police were more likely to be male and aged between 30 to 49 years. Clinical factors related to police referrals including a higher triage assessment level, chief problems included violence, disturbance, substance use, less anxiety, and a diagnosis of unspecified psychosis. The triage assessment level and chief problems assessed by nurses were major predictors. These patients tended to be referred from the catchment area and during the nighttime shift, were discharged during the daytime shift, and stayed longer in the PES. Disposition arrangements such as discharge against medical advice and involuntary admission were also associated with police referrals. Patients referred by the police to the PES were those with more severe psychiatric problems and illnesses assessed by psychiatric nurses and psychiatrists. They tended to have more complex service utilization at the PES. © 2015 Wiley Publishing Asia Pty Ltd.

    Forensic DNA Phenotyping (FDP), i.e. the prediction of human externally visible traits from DNA, has become a fast growing subfield within forensic genetics due to the intelligence information it can provide from DNA traces. FDP outcomes can help focus police investigations in search of unknown perpetrators, who are generally unidentifiable with standard DNA profiling. Therefore, we previously developed and forensically validated the IrisPlex DNA test system for eye colour prediction and the HIrisPlex system for combined eye and hair colour prediction from DNA traces. Here we introduce and forensically validate the HIrisPlex-S DNA test system (S for skin) for the simultaneous prediction of eye, hair, and skin colour from trace DNA. This FDP system consists of two SNaPshot-based multiplex assays targeting a total of 41 SNPs via a novel multiplex assay for 17 skin colour predictive SNPs and the previous HIrisPlex assay for 24 eye and hair colour predictive SNPs, 19 of which also contribute to skin colour prediction. The HIrisPlex-S system further comprises three statistical prediction models, the previously developed IrisPlex model for eye colour prediction based on 6 SNPs, the previous HIrisPlex model for hair colour prediction based on 22 SNPs, and the recently introduced HIrisPlex-S model for skin colour prediction based on 36 SNPs. In the forensic developmental validation testing, the novel 17-plex assay performed in full agreement with the Scientific Working Group on DNA Analysis Methods (SWGDAM) guidelines, as previously shown for the 24-plex assay. Sensitivity testing of the 17-plex assay revealed complete SNP profiles from as little as 63 pg of input DNA, equalling the previously demonstrated sensitivity threshold of the 24-plex HIrisPlex assay. Testing of simulated forensic casework samples such as blood, semen, saliva stains, of inhibited DNA samples, of low quantity touch (trace) DNA samples, and of artificially degraded DNA samples as well as

    2016-09-01

    Due to the popularity of Android devices and applications (apps), Android forensics is one of the most studied topics within mobile forensics. Communication apps, such as instant messaging and Voice over IP (VoIP), are one popular app category used by mobile device users, including criminals. Therefore, a taxonomy outlining artifacts of forensic interest involving the use of Android communication apps will facilitate the timely collection and analysis of evidentiary materials from such apps. In this paper, 30 popular Android communication apps were examined, where a logical extraction of the Android phone images was collected using XRY, a widely used mobile forensic tool. Various information of forensic interest, such as contact lists and chronology of messages, was recovered. Based on the findings, a two-dimensional taxonomy of the forensic artifacts of the communication apps is proposed, with the app categories in one dimension and the classes of artifacts in the other dimension. Finally, the artifacts identified in the study of the 30 communication apps are summarized using the taxonomy. It is expected that the proposed taxonomy and the forensic findings in this paper will assist forensic investigations involving Android communication apps. © 2016 American Academy of Forensic Sciences.

    Full Text Available The Domain Name Service (DNS is a critical core component of the global Internet and integral to the majority of corporate intranets. It provides resolution services between the human-readable name-based system addresses and the machine operable Internet Protocol (IP based addresses required for creating network level connections. Whilst structured as a globally dispersed resilient tree data structure, from the Global and Country Code Top Level Domains (gTLD/ccTLD down to the individual site and system leaf nodes, it is highly resilient although vulnerable to various attacks, exploits and systematic failures. This paper examines the history along with the rapid growth of DNS up to its current critical status. It then explores the often overlooked value of DNS query data; from packet traces, DNS cache data, and DNS logs, with its use in System Forensics and more frequently in Network Forensics, extrapolating examples and experiments that enhance knowledge.Continuing on, it details the common attacks that can be used directly against the DNS systems and services, before following on with the malicious uses of DNS in direct system attacks, Distributed Denial of Service (DDoS, traditional Denial of Service (DOS attacks and malware. It explores both cyber-criminal activities and cyber-warfare based attacks, and also extrapolates from a number of more recent attacks the possible methods for data exfiltration. It explores some of the potential analytical methodologies including; common uses in Intrusion Detection Systems (IDS, as well as infection and activity tracking in malware traffic analysis, and covers some of the associated methods around technology designed to defend against, mitigate, and/or manage these and other risks, plus the effect that ISP and nation states can have by direct manipulation of DNS queries and return traffic.This paper also investigates potential behavioural analysis and time-lining, which can then be used for the

    2016-10-01

    Full Text Available The aim of digital forensics is to extract information to answer the 5Ws (Why, When, Where, What, and Who from the data extracted from the evidence. In order to achieve this, most digital forensic processes assume absolute control of digital evidence. However, in a cloud environment forensic investigation, this is not always possible. Additionally, the unique characteristics of cloud computing create new technical, legal and architectural challenges when conducting a forensic investigation. We propose a hypothetical scenario to uncover and explain the challenges forensic practitioners face during cloud investigations. Additionally, we also provide solutions to address the challenges. Our hypothetical case scenario has shown that, in the long run, better live forensic tools, development of new methods tailored for cloud investigations and new procedures and standards are indeed needed. Furthermore, we have come to the conclusion that forensic investigations biggest challenge is not technical but legal.

    1994-06-01

    To address the forensic needs of living patients, the Department of Emergency Medicine at the University of Louisville School of Medicine in Louisville, Kentucky, USA initiated the first clinical forensic medicine training programme in the USA. In July 1991, formal training in clinical forensic medicine was incorporated into the core curriculum of the USA's second oldest academic emergency medicine training programme. The University of Louisville, in cooperation with the Kentucky Medical Examiner's Office, developed the curriculum to provide the emergency physician with the knowledge base and technical skills to perform forensic evaluations of living patients. Forensic lectures are given monthly by local and regional forensic experts including: forensic pathologists, prosecuting attorneys, firearm and ballistics examiners, law enforcement officers, forensic chemists and forensic odontologists. Topics which are presented include: forensic pathology, forensic photography, ballistics and firearms analysis, paediatric physical and sexual assault, crime scene investigation, forensic odontology, courtroom and expert testimony and the forensic evaluation of penetrating trauma. As a result of the introduction of clinical forensic medicine into the core curriculum of an emergency medicine training programme the residents are now actively addressing the forensic issues encountered in the Emergency department. Key, often short-lived forensic evidence, which was frequently overlooked or discarded while delivering patient care is now recognized, documented and preserved. The development and introduction of a clinical forensic medicine curriculum into emergency medicine training has greatly enhanced the emergency physician's ability to recognize, document and address the forensic needs of their patients who are victims of violent and non-fatal trauma.

    Mandatory medical examinations (MMEs) of workers should be based on the health and safety requirements that are needed for effectively performing the relevant work. For police personnel in the Netherlands, no job-specific MME exists that takes the specific tasks and duties into account. To provide the Dutch National Police with a knowledge base for job-specific MMEs for police personnel that will lead to equitable decisions from an occupational health perspective about who can perform police duties. We used a stepwise mixed-methods approach in which we included interviews with employees and experts and a review of the national and international literature. We determined the job demands for the various police jobs, determined which were regarded as specific job demands and formulated the matching health requirements as specific as possible for each occupation. A total of 21 specific job demands were considered relevant in different police jobs. These included biomechanical, physiological, physical, emotional, psychological/cognitive and sensory job demands. We formulated both police-generic and job-specific health requirements based on the specific job demands. Two examples are presented: bike patrol and criminal investigation. Our study substantiated the need for job-specific MMEs for police personnel. We found specific job demands that differed substantially for various police jobs. The corresponding health requirements were partly police-generic, and partly job-specific. © The Author 2017. Published by Oxford University Press on behalf of the Society of Occupational Medicine.

    A review of forensic chemical drug testing in hair is given. Applications for analysis of hair are described. The special problems linked to the determination of drugs in hair such as contamination, differences in sex and ethnic groups and cosmetic pretreatment of the hair are outlined. It is concluded that greater knowledge of hair analysis is needed before the results can be used for toxicological evaluation at the same level as blood. On the other hand, a chemical hair analysis might expose a (mis)use of drugs and follow it step by step up to half a year back in time. In this way, it may supplement a systematic toxicological analysis (STA) for 'a general unknown' for use by police and forensic pathologists.

    To describe the changes in death rates and causes of deaths in Norwegian police cells during the last 2 decades. To review reports on death rates in police cells that have been published in medical journals and elsewhere, and discuss the difficulties of comparing death rates between countries. Data on deaths in Norwegian police cells were collected retrospectively in 2002 and 2012 for two time periods: 1993-2001 (period 1) and 2003-2012 (period 2). Several databases were searched to find reports on deaths in police cells from as many countries as possible. The death rates in Norwegian police cells reduced significantly from 0.83 deaths per year per million inhabitants (DYM) in period 1 to 0.22 DYM in period 2 (p police cells reduced by about 75% over a period of approximately 10 years. This is probably mainly due to individuals with severe alcohol intoxication no longer being placed in police cells. However, there remain large methodology difficulties in comparing deaths rates between countries. Copyright © 2015 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

    A rapid and effective preparative procedure has been evaluated for the accurate determination of low-energy (40–200 keV) gamma-emitting radionuclides ({sup 210}Pb, {sup 234}Th, {sup 226}Ra, {sup 235}U) in uranium ores and uranium ore concentrates (UOCs) using high-resolution gamma ray spectrometry. The measurement of low-energy gamma photons is complicated in heterogeneous samples containing high-density mineral phases and in such situations activity concentrations will be underestimated. This is because attenuation corrections, calculated based on sample mean density, do not properly correct where dense grains are dispersed within a less dense matrix (analogous to a nugget effect). The current method overcomes these problems using a lithium tetraborate fusion that readily dissolves all components including high-density, self-attenuating minerals/compounds. This is the ideal method for dissolving complex, non-volatile components in soils, rocks, mineral concentrates, and other materials where density reduction is required. Lithium borate fusion avoids the need for theoretical efficiency corrections or measurement of matrix matched calibration standards. The resulting homogeneous quenched glass produced can be quickly dissolved in nitric acid producing low-density solutions that can be counted by gamma spectrometry. The effectiveness of the technique is demonstrated using uranium-bearing Certified Reference Materials and provides accurate activity concentration determinations compared to the underestimated activity concentrations derived from direct measurements of a bulk sample. The procedure offers an effective solution for initial nuclear forensic studies where complex refractory minerals or matrices exist. It is also significantly faster, safer and simpler than alternative approaches. - Highlights: • Low energy gamma photons (<200 keV) are attenuated in U-bearing compounds. • Corrections based on bulk density do not yield accurate activity

    Use of force [UOF] by police can result in serious injuries and fatalities. The risk of significant injuries associated with different force modalities is poorly defined. We sought to determine the incidence of police UOF and compare the likelihood of significant injury with different force modalities. A prospective multicenter observational study of all UOF incidents was conducted via mandatory UOF investigations at three mid-sized police agencies over a two year period. Expert physicians reviewed police and medical records to determine injury severity using a priori injury severity stratification criteria. There were 893 UOF incidents, representing a UOF rate of 0.086% of 1,041,737 calls for service (1 in 1167) and 0.78% of 114,064 criminal arrests(1 in 128). Suspects were primarily young (mean age, 31 years; range, 12-86 years) males (89%). The 1,399 force utilizations included unarmed physical force (n = 710, 51%), CEWs (504, 30%), chemical (88, 6.3%), canines (47, 3.4%), impact weapons (9, 0.6%), kinetic impact munitions (8, 0.6%), firearms (6, 0.4%), and other (27, 1.9%). Among 914 suspects, 898 (98%) sustained no or mild injury after police UOF. Significant (moderate or severe) injuries occurred in 16 (1.8%) subjects. Logistic regression analysis shows these are most associated with firearm and canine use. There was one fatality (0.1%) due to gunshots. No significant injuries occurred among 504 CEW uses (0%; 95% confidence interval, 0.0-0.9%). Of the 355 suspects transported to a medical facility, 78 (22%) were hospitalized. The majority of hospitalizations were unrelated to UOF (n = 59, 76%), whereas a minority (n = 19, 24%) were due to injuries related to police UOF. Police UOF is rare. When force is used officers most commonly rely on unarmed physical force and CEWs. Significant injuries are rare. Transport for medical evaluation is a poor surrogate for significant injury due to UOF. Epidemiological, level II.

  4. High Performance Proactive Digital Forensics

    2012-01-01

    With the increase in the number of digital crimes and in their sophistication, High Performance Computing (HPC) is becoming a must in Digital Forensics (DF). According to the FBI annual report, the size of data processed during the 2010 fiscal year reached 3,086 TB (compared to 2,334 TB in 2009) and the number of agencies that requested Regional Computer Forensics Laboratory assistance increasing from 689 in 2009 to 722 in 2010. Since most investigation tools are both I/O and CPU bound, the next-generation DF tools are required to be distributed and offer HPC capabilities. The need for HPC is even more evident in investigating crimes on clouds or when proactive DF analysis and on-site investigation, requiring semi-real time processing, are performed. Although overcoming the performance challenge is a major goal in DF, as far as we know, there is almost no research on HPC-DF except for few papers. As such, in this work, we extend our work on the need of a proactive system and present a high performance automated proactive digital forensic system. The most expensive phase of the system, namely proactive analysis and detection, uses a parallel extension of the iterative z algorithm. It also implements new parallel information-based outlier detection algorithms to proactively and forensically handle suspicious activities. To analyse a large number of targets and events and continuously do so (to capture the dynamics of the system), we rely on a multi-resolution approach to explore the digital forensic space. Data set from the Honeynet Forensic Challenge in 2001 is used to evaluate the system from DF and HPC perspectives.

  7. Computer Forensics for Graduate Accountants: A Motivational Curriculum Design Approach

    Directory of Open Access Journals (Sweden)

    2010-06-01

    Full Text Available Computer forensics involves the investigation of digital sources to acquire evidence that can be used in a court of law. It can also be used to identify and respond to threats to hosts and systems. Accountants use computer forensics to investigate computer crime or misuse, theft of trade secrets, theft of or destruction of intellectual property, and fraud. Education of accountants to use forensic tools is a goal of the AICPA (American Institute of Certified Public Accountants. Accounting students, however, may not view information technology as vital to their career paths and need motivation to acquire forensic knowledge and skills. This paper presents a curriculum design methodology for teaching graduate accounting students computer forensics. The methodology is tested using perceptions of the students about the success of the methodology and their acquisition of forensics knowledge and skills. An important component of the pedagogical approach is the use of an annotated list of over 50 forensic web-based tools.

  8. Application of DNA-based methods in forensic entomology.

    Wells, Jeffrey D; Stevens, Jamie R

    2008-01-01

    A forensic entomological investigation can benefit from a variety of widely practiced molecular genotyping methods. The most commonly used is DNA-based specimen identification. Other applications include the identification of insect gut contents and the characterization of the population genetic structure of a forensically important insect species. The proper application of these procedures demands that the analyst be technically expert. However, one must also be aware of the extensive list of standards and expectations that many legal systems have developed for forensic DNA analysis. We summarize the DNA techniques that are currently used in, or have been proposed for, forensic entomology and review established genetic analyses from other scientific fields that address questions similar to those in forensic entomology. We describe how accepted standards for forensic DNA practice and method validation are likely to apply to insect evidence used in a death or other forensic entomological investigation.

The authors show in that book how the restructuring of capitalism as a response to the crisis of the 1970s - which was the last major crisis of world capitalism until the current one hit in 2008 -led in the United Kingdom and elsewhere to an "exceptional state," by which they meant a situation in which there was an ongoing breakdown of consensual mechanisms of social control and a growing authoritarianism.

    To investigate fatal factors involved in labor-related accidents and events, forensic postmortem cases (n=874) during the past 6 years (1996-2001) at our institute were reviewed. Among them, there were 67 labor-related fatalities, showing a varied annual incidence (6-15 cases per year). All the victims were males (19-68 years of age). The most common sites of the accidents were manufacturing factories (n=21, 31.3%), warehouses (n=14, 20.9%), construction and demolition sites (n=11 and n=5, 16.4 and 7.5%, respectively). There were some characteristic types of accidents: falls from heights at work during construction and maintenance, and crushes by heavy materials and moving vehicles in transportation, by collapsing structures at demolition sites or by working machinery in factories. The most severely injured body regions were usually the head in falls (n=13/23) and the chest/abdomen in crushes (n=19/32). Most of the victims (n=54, 80.6%) died within 24 h. Alcohol was detected only in four cases. Most accidents were considered to be due to carelessness and simple fault of the workers without any significant relationship to their professional training and career.

  11. Organizational Justice and the Intent to Share: Knowledge Sharing Practices among Forensic Experts in Turkey

    Directory of Open Access Journals (Sweden)

    Can, Ahmet

    2013-12-01

    Full Text Available Organizational climate and organization culture can be some of the leading factors in hindering knowledge sharing within the organization. It is generally accepted that successful knowledge management practice, including knowledge sharing, comes as a result of a conducive and knowledge sharing friendly environment. Organizations that promote and reward collective work generate a trustful and a more collaborative learning culture. The perception of fairness in an organization has been considered an important indicator of employee behavior, attitude, and motivation. This study investigates organizational justice perception and its impact on knowledge sharing practices among forensic experts in the Turkish National Police. The study findings revealed that senior officers, who are experts in the field, have the strongest organizational justice perception. Meanwhile, noncommissioned officers or technicians bear positive but comparatively weaker feelings about the existence of justice within the organization. The study argues that those who satisfy their career expectations tend to have a higher organizational justice perception.

  14. [Continuous challenges in Japanese forensic toxicology practice: strategy to address specific goals].

    Science.gov (United States)

    Kageura, Mitsuyoshi

    2002-09-01

    In this paper, the status quo of forensic toxicology in Japan and the West is surveyed and a strategy to address future goals of Japanese forensic toxicology is proposed. Forensic toxicology in the West consists of three main areas--post-mortem forensic toxicology, human-performance forensic toxicology and forensic urine drug testing. In Japan, post-mortem forensic toxicology is practiced in university forensic medicine departments while most of the human-performance forensic toxicology is carried out in police laboratories. However, at least at present, strictly controlled workplace urine drug testing is not being performed, despite the abuse of drugs even by uniformed members of the National Defence Forces and police. For several years, the author has been introducing Western forensic toxicology guidelines and recommendations, translated into Japanese with the help of Western forensic toxicologists, to Japanese forensic toxicologists. Western forensic toxicology practice is at an advanced stage, whereas Japanese practice is in a critical condition and holds many problems awaiting solution, as exemplified by the urine drug testing in police laboratories. There is never any sample left for re-examination by the defence in all cases, though the initial volume of the urine sample available for examination is 30-50 ml. Only one organisation carries out everything from sampling to reporting and, in addition, the parent drug and its metabolites are not quantified. It is clear that the police laboratories do not work within good laboratory practice guidelines, nor do they have quality manuals or standard operating procedures manuals. A basic change in Japanese forensic toxicology practice is now essential. The author strongly recommends that, first of all, Japanese toxicologists should prepare forensic toxicology guidelines based on the Western models. The guidelines would progress the following objectives for forensic toxicology laboratories: 1) to have documented good

    2007-01-01

    Recent media coverage has highlighted cases in which young suspects were wrongly convicted because they provided interrogation-induced false confessions. Although youth may be more highly suggestible and easily influenced by authority than adults, police are trained to use the same psychologically coercive and deceptive tactics with youth as with adults. This investigation is the first standard documentation of the reported interrogation practices of law enforcement and police beliefs about the reliability of these techniques and their knowledge of child development. Participants were 332 law enforcement officers who completed surveys about interrogation procedures and developmental issues pertaining to youth. Results indicated that, while police acknowledge some developmental differences between youth and adults, there were indications that (1) how police perceive youth in general and how they perceive and treat them in the interrogation context may be contradictory and (2) their general view is that youth can be dealt with in the same manner as adults.

    2017-03-01

    Human factors and their implications for forensic science have attracted increasing levels of interest across criminal justice communities in recent years. Initial interest centred on cognitive biases, but has since expanded such that knowledge from psychology and cognitive science is slowly infiltrating forensic practices more broadly. This article highlights a series of important findings and insights of relevance to forensic practitioners. These include research on human perception, memory, context information, expertise, decision-making, communication, experience, verification, confidence, and feedback. The aim of this article is to sensitise forensic practitioners (and lawyers and judges) to a range of potentially significant issues, and encourage them to engage with research in these domains so that they may adapt procedures to improve performance, mitigate risks and reduce errors. Doing so will reduce the divide between forensic practitioners and research scientists as well as improve the value and utility of forensic science evidence.

    To diagnose the occurrence and stage of stress among military police enlisted personnel and officers in the city of Natal (the capital of the state of Rio Grande do Norte, Brazil), and to determine the prevalence of physical and mental symptoms. This cross-sectional descriptive study investigated a sample of 264 individuals from a population of 3,193 military personnel from the Natal police command. The data were collected between June 2004 and January 2005 using Lipp's Adult Stress Symptoms Inventory (Inventário de Sintomas de Stress para Adultos de Lipp). The research assessed: (1) presence of stress, (2) the stage of stress (alert, resistance, near-burnout, and burnout), (3) the prevalence of physical and mental symptoms, and (4) the relationship between stress and police unit, rank, gender, drinking, smoking, educational level, marital status, age, years of police service, and salary. No stress symptoms were found in 52.6% of the sample; 47.4% had symptoms. Of the 47.4% of the police personnel with stress symptoms, they were distributed as: 3.4% in the alert stage, 39.8% in the resistance stage, 3.8% in the near-burnout stage, and 0.4% in the burnout stage. Psychological symptoms were recorded in 76.0% of the police personnel with stress, and physical symptoms in 24.0% of them. Of the variables investigated, only gender was related to stress (P = 0.0337), with the female police personnel being more likely to suffer from stress. The levels of stress and symptoms do not indicate a critical situation of fatigue. However, it is recommended that the police take preventive actions, including implementing an effective program for the diagnosis of, training on, and control of stress.

    2012-01-01

    How is jurisdiction transferred from an individual's biological body to agents of power such as the police, public prosecutors, and the judiciary, and what happens to these biological bodies when transformed from private into public objects? These questions are examined by analysing bodies situated at the intersection of science and law. More specifically, the transformation of ‘private bodies’ into ‘public bodies’ is analysed by going into the details of forensic DNA profiling in the Dutch jurisdiction. It will be argued that various ‘forensic genetic practices’ enact different forensic genetic bodies'. These enacted forensic genetic bodies are connected with various infringements of civil rights, which become articulated in exploring these forensic genetic bodies’‘normative registers’.

The study aimed to determine the level of animosity exhibited in speech, to analyse socio-ethnic distance, to observe reactions towards measures designed to improve the situation of vulnerable groups, to consider the relationship among institutions regarding their responsibility for the occurrence of discrimination and its impact on the reduction of it, to discuss personal experiences of discrimination and to analyse attitudes regarding certain claims of a stereotypical character. Moreover, the paper also presents a comparative analysis of similar surveys on the perception of citizens towards discrimination that have thus far been conducted in Serbia. The results demonstrated that the police in Serbia did not exhibit a particularly discriminatory attitude towards citizens. It is important to note that the most prominent socio-ethnic distances were exhibited in relation to Roma and members of the LGBT community.

  8. Naturalistic decision making in forensic science: toward a better understanding of decision making by forensic team leaders.

    Helsloot, Ira; Groenendaal, Jelle

    2011-07-01

    This study uses the naturalistic decision-making (NDM) perspective to examine how Dutch forensic team leaders (i.e., the officers in charge of criminal forensic research from the crime scene until the use of laboratory assistance) make decisions in real-life settings and identifies the contextual factors that might influence those decisions. First, a focus group interview was conducted to identify four NDM mechanisms in day-to-day forensic decision making. Second, a serious game was conducted to examine the influence of three of these contextual mechanisms. The results uncovered that forensic team leaders (i) were attracted to obtain further information when more information was initially made available, (ii) were likely to devote more attention to emotionally charged cases, and (iii) used not only forensic evidence in the decision making but also tactical, unverified information of the police inquiry. Interestingly, the measured contextual influences did not deviate significantly from a control group of laypeople. © 2011 American Academy of Forensic Sciences.

    1. Forensic nurses frequently work in violent settings without regard for self-preservation to save the lives of injured individuals or investigate the deaths of deceased individuals. 2. Cases involving children and victims with disfiguring injuries, and incidents when their personal safety was compromised are most disturbing to forensic nurses. 3. Providing means for health care professionals to cope appropriately encourages healthy healing. 4. Forensic nurses must learn to self-assess and recognize the signs and symptoms associated with unhealthy coping, depression, or posttraumatic stress disorder.

  11. Significance of Dental Records in Personal Identification in Forensic Sciences

    Directory of Open Access Journals (Sweden)

    Vagish Kumar L Shanbhag

    2016-01-01

    Full Text Available Forensic odontology is a branch that connects dentistry and the legal profession. One of the members in the forensic investigation team is a dentist. Dentists play an important and significant role in various aspects of the identification of persons in various forensic circumstances. However, several dentists and legal professionals are quite ignorant of this fascinating aspect of forensic odontology. A need was felt to fill this gap. The dental record is a legal document possessed by the dentist and it contains subjective and objective information about the patient. A PubMed search and Google search were done for articles highlighting the importance of dental records in forensic sciences using the key words "forensic odontology, forensic dentistry, forensic dentists, identification, dental records, and dental chart". A total of 42 articles relevant to the title of the article were found and reviewed. The present article highlights the role of dentists in forensic sciences, their possible contributions to forensics, and the various aspects of forensic dentistry, thus bridging the gap of knowledge between the legal and the dental fraternities.

  12. A clean bill of health? The efficacy of an NHS commissioned outsourced police custody healthcare service.

    Science.gov (United States)

    de Viggiani, Nick

    2013-08-01

    Police custody healthcare services for detainees in the UK are most commonly outsourced to independent healthcare providers who employ custody nurses and forensic physicians to deliver forensic healthcare services. A pilot was introduced in 2008 by the Department of Health to explore the efficacy of commissioning custody healthcare via the NHS, in the wake of the 2005-2006 shift of prison healthcare to the NHS. The objective was to improve quality and accountability through NHS commissioning and the introduction of NHS governance to the management and delivery of custody healthcare. This article discusses key themes that arose from the project evaluation, which focused on the commissioning relationship between the police, the NHS commissioner and the private healthcare provider. The evaluation observed an evolving relationship between the police, the local NHS and the front-line nurses, which was complicated by the quite distinctive professional values and ideologies operating, with their contrasting organisational imperatives and discordant values and principles. A key challenge for commissioners is to develop synergy between operational and strategically located stakeholders so that they can work effectively towards common goals. Government policy appears to remain focused on creating safe, supportive and humane custody environments that balance criminal justice and health imperatives and support the rights and needs of detainees, victims, professionals and the public. This remains an ambitious agenda and presents a major challenge for new criminal justice health partnerships. Copyright © 2013 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

    2013-03-01

    The consumption of psychoactive substances by civil and military police of the city of Rio de Janeiro was investigated. Data was gathered from two cross-sectional studies on a questionnaire on work and health conditions given to a sample from the two corporations. The results show higher frequencies of regular consumption of tobacco (23.3% by civil police and 19.1% by military police), daily use of alcohol (12% by civil police and 11% by military police) and tranquilizers in the past year (13.3% by civil police and 10.1% by military police). The consumption of marijuana among officers was 0.1% by civil police and 1.1% by military police, and cocaine use among the military police was 1.1%. Alcohol consumption proved to be intense and causes problems at work and in the social and family relationships of these officers. The need for preventive policies for addiction and the possible underestimation of information on illicit substances is emphasized.

    The creation of new technologies and their application to forensic science is key to the field's development. Rapid DNA profiling is one such area of research which has grown in response to a desire from enforcement authorities for in-house forensic DNA processing and rapid access to forensic genetic intelligence. However, introducing novel technologies into the forensics market must be carefully monitored and controlled as the success or failure of any technology ultimately has long standing implications for victims, suspects, and also to Police and forensic practitioners.

  19. Peer review in forensic science.

    Science.gov (United States)

    Ballantyne, Kaye N; Edmond, Gary; Found, Bryan

    2017-08-01

    Peer review features prominently in the forensic sciences. Drawing on recent research and studies, this article examines different types of peer review, specifically: editorial peer review; peer review by the scientific community; technical and administrative review; and verification (and replication). The article reviews the different meanings of these quite disparate activities and their utility in relation to enhancing performance and reducing error. It explains how forensic practitioners should approach and use peer review, as well as how it should be described in expert reports and oral testimony. While peer review has considerable potential, and is a key component of modern quality management systems, its actual value in most forensic science settings has yet to be determined. In consequence, forensic practitioners should reflect on why they use specific review procedures and endeavour to make their actual practices and their potential value transparent to consumers; whether investigators, lawyers, jurors or judges. Claims that review increases the validity of a scientific technique or accuracy of opinions within a particular case should be avoided until empirical evidence is available to support such assertions.

  20. Microbial Forensics: A Scientific Assessment

    Energy Technology Data Exchange (ETDEWEB)

    Keim, Paul

    2003-02-17

    Microorganisms have been used as weapons in criminal acts, most recently highlighted by the terrorist attack using anthrax in the fall of 2001. Although such ''biocrimes'' are few compared with other crimes, these acts raise questions about the ability to provide forensic evidence for criminal prosecution that can be used to identify the source of the microorganisms used as a weapon and, more importantly, the perpetrator of the crime. Microbiologists traditionally investigate the sources of microorganisms in epidemiological investigations, but rarely have been asked to assist in criminal investigations. A colloquium was convened by the American Academy of Microbiology in Burlington, Vermont, on June 7-9, 2002, in which 25 interdisciplinary, expert scientists representing evolutionary microbiology, ecology, genomics, genetics, bioinformatics, forensics, chemistry, and clinical microbiology, deliberated on issues in microbial forensics. The colloquium's purpose was to consider issues relating to microbial forensics, which included a detailed identification of a microorganism used in a bioattack and analysis of such a microorganism and related materials to identify its forensically meaningful source--the perpetrators of the bioattack. The colloquium examined the application of microbial forensics to assist in resolving biocrimes with a focus on what research and education are needed to facilitate the use of microbial forensics in criminal investigations and the subsequent prosecution of biocrimes, including acts of bioterrorism. First responders must consider forensic issues, such as proper collection of samples to allow for optimal laboratory testing, along with maintaining a chain of custody that will support eventual prosecution. Because a biocrime may not be immediately apparent, a linkage must be made between routine diagnosis, epidemiological investigation, and criminal investigation. There is a need for establishing standard operating

  1. Policing Diversity: Examining Police Resistance to Training Reforms for Transgender People in Australia.

    Miles-Johnson, Toby

    2016-01-01

    Using field notes collected from participant observation of Australian police officers training to work with the transgender community, the current research builds on previous work examining social identity theory (Tajfel, 2010) to explain how one training program implemented to educate police about transgender people challenges police culture. This research determines that police culture, training procedures, and stereotypes of gender are equally influential on police perceptions of all transgender people. Overall, the results indicate that negative police perceptions toward police training reforms strengthen in-group identity of police, and negative out-group perceptions of transgender people.

  3. Evaluation of forensic medical history taking from the child in cases of child physical and sexual abuse and neglect.

    Drummond, Rachel; Gall, John A M

    2017-02-01

    Suspected child physical abuse, sexual abuse and neglect are not uncommon presentations. As part of the assessment of these cases, a forensic medical history may be taken. This forensic history is used not only to determine the steps necessary to address the child's wellbeing but also to direct the forensic examination. Currently, there is no clear consensus on whether or not a forensic medical history should consistently be considered an integral element within the paediatric forensic evaluation. This study examines the value derived by the medical practitioner taking a forensic medical history rather than relying on hearsay evidence when a child presents for an assessment. A retrospective review of paediatric cases seen by the Victorian Forensic Paediatric Medical Service (VFPMS) between 2014 and 2015 was undertaken. 274 forensic case reports were reviewed and the data was entered into an Excel spread sheet and analysed using chi squared tests within STATA ® . With increasing age of the child, a forensic medical history is significantly more likely to be taken. Additional information is made available to the medical practitioner what would otherwise have been provided if the medical practitioner relied only on the interview conducted by the police. Discrepancies observed between the official third parties (police or child protection) report of what a child has said and what the child says to the medical practitioner decrease with age, as do discrepancies observed between the child's version of events and a third party's (eg. parents, caregivers, friends) version of events. The study showed that by taking a forensic medical history from the child additional information can be obtained. Further, that there is a value in the examining medical practitioner taking a forensic medical history from children in cases of child physical and sexual abuse and neglect.

    Sexual assault is a serious offense and identification of body fluids originating from sexual activity has been a crucial aspect of forensic investigations for a long time. While reliable tests for the detection of semen and saliva have been successfully implemented into forensic laboratories, the detection of other body fluids, such as vaginal or menstrual fluid, is more challenging. Especially, the discrimination between peripheral and menstrual blood can be highly relevant for police investigations because it provides potential evidence regarding the issue of consent. We report the forensic validation of an immunochromatographic test that allows for such discrimination in forensic stains, the SERATEC PMB test, and its performance on real casework samples. The PMB test is a duplex test combining human hemoglobin and D-dimer detection and was developed for the identification of blood and menstrual fluid, both at the crime scene and in the laboratory. The results of this study showed that the duplex D-dimer/hemoglobin assay reliably detects the presence of human hemoglobin and identifies samples containing menstrual fluid by detecting the presence of D-dimers. The method distinguished between menstrual and peripheral blood in a swab from a historical artifact and in real casework samples of alleged sexual assaults. Results show that the development of the new duplex test is a substantial progress towards analyzing and interpreting evidence from sexual assault cases.

It next discusses the kinds of psychological reactions commonly seen in workers who face these kinds of proceedings. Finally, the article offers a set of practical psychological coping strategies and procedural recommendations for dealing with the stresses of an investigation, administrative action, or litigation, and for mitigating their effects on one's life and career.

  7. Forensic radiology: An emerging tool in identification

    2015-01-01

    Full Text Available In any mass disaster condition, identification of the person is most important. For this purpose, the forensic investigators use different methods for identifying the dead. They consider skeletal remains of the dead as the initial step in identification. Radiographs carry great evidence to act as antemortem records and also assist in identifying the person, age, gender, race, etc. Forensic dentistry is also emerging as a new branch in forensics. So, the forensic dentist must be aware of different techniques, developments, and resources to incorporate the technology in order to achieve success in human identification. So, our aim of the present review is to focus on different radiological techniques and new developments available for successful identification of the dead.

    2007-12-01

    The prevalence and profile of adults with a history of traumatic brain injury (TBI) has not been studied in large North American forensic mental health populations. This study investigated how adults with a documented history of TBI differed with the non-TBI forensic population with respect to demographics, psychiatric diagnoses and history of offences. A retrospective chart review of all consecutive admissions to a forensic psychiatry programme in Toronto, Canada was conducted. Information on history of TBI, psychiatric diagnoses, living environments and types of criminal offences were obtained from medical records. History of TBI was ascertained in 23% of 394 eligible patient records. Compared to those without a documented history of TBI, persons with this history were less likely to be diagnosed with schizophrenia but more likely to have alcohol/substance abuse disorder. There were also differences observed with respect to offence profiles. This study provides evidence to support routine screening for a history of TBI in forensic psychiatry.

    Dental injuries, especially of the incisors, caused by punches in violent criminal attacks could be seen in daily forensic casework involving the identification of injuries to a living body. Sometimes, when there is neither circumstantial evidence nor information about the surrounding circumstances, it is difficult to discern the cause of these injuries and the manner in which they were inflicted. As an example of clinical forensic medicine, we present the case of a 58-year-old woman whose teeth were injured when fighting with her son-in-law over household affairs with no witnesses present. The two parties had conflicting stories about the cause of the woman's injury. The woman claimed that her teeth were lost while she was being beaten by her son-in-law, and the man argued that the damage to his mother-in-law's teeth was self-inflicted when she bit his fingers. The police attending the crime called for a forensic examination. Forensic practitioners analysed the mechanism of the tooth loss using multi-slice spiral computed tomography (MSCT) and imaging reconstruction technology. Local alveolar bone (medial alveolar) fracture and a small area of alveolar bone loss were found on MSCT. Thus, forensic medical experts speculated that the woman's lower central and lateral incisors were lost as a result of a violent attack and were not self-inflicted. Finally, forensic practitioners helped police in avoiding a miscarriage of justice and wrongful conviction.

  16. Experiences with policing among people who inject drugs in Bangkok, Thailand: a qualitative study.

    Directory of Open Access Journals (Sweden)

    Kanna Hayashi

    2013-12-01

    Full Text Available Despite Thailand's commitment to treating people who use drugs as "patients" not "criminals," Thai authorities continue to emphasize criminal law enforcement for drug control. In 2003, Thailand's drug war received international criticism due to extensive human rights violations. However, few studies have since investigated the impact of policing on drug-using populations. Therefore, we sought to examine experiences with policing among people who inject drugs (PWID in Bangkok, Thailand, between 2008 and 2012.Between July 2011 and June 2012, semi-structured, in-depth interviews were conducted with 42 community-recruited PWID participating in the Mitsampan Community Research Project in Bangkok. Interviews explored PWID's encounters with police during the past three years. Audio-recorded interviews were transcribed verbatim, and a thematic analysis was conducted to document the character of PWID's experiences with police. Respondents indicated that policing activities had noticeably intensified since rapid urine toxicology screening became available to police. Respondents reported various forms of police misconduct, including false accusations, coercion of confessions, excessive use of force, and extortion of money. However, respondents were reluctant to report misconduct to the authorities in the face of social and structural barriers to seeking justice. Respondents' strategies to avoid police impeded access to health care and facilitated transitions towards the misuse of prescribed pharmaceuticals. The study's limitations relate to the transferability of the findings, including the potential biases associated with the small convenience sample.This study suggests that policing in Bangkok has involved injustices, human rights abuses, and corruption, and policing practices in this setting appeared to have increased PWID's vulnerability to poor health through various pathways. Novel to this study are findings pertaining to the use of urine drug

    Andersson, M Gunnar; Sundström, Anders; Lindström, Anders

    2013-09-01

    In the aftermath of a CBRN incident, there is an urgent need to reconstruct events in order to bring the perpetrators to court and to take preventive actions for the future. The challenge is to discriminate, based on available information, between alternative scenarios. Forensic interpretation is used to evaluate to what extent results from the forensic investigation favor the prosecutors' or the defendants' arguments, using the framework of Bayesian hypothesis testing. Recently, several new scientific disciplines have been used in a forensic context. In the AniBioThreat project, the framework was applied to veterinary forensic pathology, tracing of pathogenic microorganisms, and forensic entomology. Forensic entomology is an important tool for estimating the postmortem interval in, for example, homicide investigations as a complement to more traditional methods. In this article we demonstrate the applicability of the Bayesian framework for evaluating entomological evidence in a forensic investigation through the analysis of a hypothetical scenario involving suspect movement of carcasses from a clandestine laboratory. Probabilities of different findings under the alternative hypotheses were estimated using a combination of statistical analysis of data, expert knowledge, and simulation, and entomological findings are used to update the beliefs about the prosecutors' and defendants' hypotheses and to calculate the value of evidence. The Bayesian framework proved useful for evaluating complex hypotheses using findings from several insect species, accounting for uncertainty about development rate, temperature, and precolonization. The applicability of the forensic statistic approach to evaluating forensic results from a CBRN incident is discussed.

    Toxicologic analysis is an integral part of death investigation, and the use or abuse of an unsuspected substance belongs in the differential diagnosis of patients who have a sudden, unexpected change in their condition. History and physical findings may alter suspicion that intoxication played a role in a patient's decline or death, but suspicions cannot be confirmed and is performed, analysis unless toxicologic no toxicologic analysis is possible unless someone collects the proper specimens necessary for analysis. In a hospital autopsy the only specimens that can rightfully be collected are those within the restrictions stated in the autopsy permit. Autopsies performed by the medical examiner do not have these restrictions. Sometimes the importance of toxicologic testing in a case is not evident until days or weeks after the change in the patient's status, thus retaining the appropriate specimens until investigation of that case has ended is important. Proper interpretation of toxicologic findings requires integrating the clinical setting and findings with the toxicologic results in a way that makes medical sense. If called upon to testify concerning findings, answer the questions truthfully, politely, and in a way that is understandable to someone who has no special training in toxicology.

    We conducted 2 studies to investigate how cultural stereotypes that depict Blacks as criminals affect the way Blacks experience encounters with police officers, expecting that such encounters induce Blacks to feel stereotype threat (i.e., concern about being judged and treated unfairly by police because of the stereotype). In Study 1, we asked Black and White participants to report how they feel when interacting with police officers in general. As predicted, Blacks, but not Whites, reported concern that police officers stereotype them as criminals simply because of their race. In addition, this effect was found for Black men but not Black women. In Study 2, we asked Black and White men to imagine a specific police encounter and assessed potential downstream consequences of stereotype threat. Consistent with Study 1, Black but not White men anticipated feeling stereotype threat in the hypothetical police encounter. Further, racial differences in anticipated threat translated into racial differences in anticipated anxiety, self-regulatory efforts, and behavior that is commonly perceived as suspicious by police officers. By demonstrating that Blacks might expect to be judged and treated unfairly by police because of the negative stereotype of Black criminality, this research extends stereotype threat theory to the new domain of criminal justice encounters. It also has practical implications for understanding how the stereotype could ironically contribute to bias-based policing and racial disparities in the justice system.

    Serological and biochemical identification methods used in forensics have several major disadvantages, such as: long time in processing biological sample and lack of sensitivity and specificity. In the last 30 years, DNA molecular analysis has become an important tool in forensic investigations. DNA profiling is based on the short tandem repeats (STR) and aids in human identification from biological samples. Forensic genetics, can provide information on the events which occurred at the crime scene or to supplement other methods of forensic identification. Currently, the methods used in identification are based on polymerase chain reaction (PCR) analyses. This method analyses the autosomal STRs, the Y-chromosome, and the mitochondrial DNA. Correlation of biological samples present at the crime scene with identification, selection, and the probative value factor is therefore the first aspect to be taken into consideration in the forensic genetic analysis. In the last decade, because of the advances in the field of molecular biology, new biomarkers such as: microRNAs (miR), messenger RNA (mRNA), and DNA methylation have been studied and proposed to be used in the forensic identifications of body fluids.

  9. Forensic anthropology and mortuary archaeology in Lithuania.

    Jankauskas, Rimantas

    2009-12-01

    Forensic anthropology (in Lithuania, as everywhere in Eastern Europe, traditionally considered as a narrower field--forensic osteology) has a long history, experience being gained both during exhumations of mass killings during the Second World War and the subsequent totalitarian regime, investigations of historical mass graves, identification of historical personalities and routine forensic work. Experts of this field (usually a branch of forensic medicine) routinely are solving "technical" questions of crime investigation, particularly identification of (usually dead) individuals. Practical implementation of the mission of forensic anthropology is not an easy task due to interdisciplinary character of the field. On one hand, physical anthropology has in its disposition numerous scientifically tested methods, however, their practical value in particular legal processes is limited. Reasons for these discrepancies can be related both to insufficient understanding of possibilities and limitations of forensic anthropology and archaeology by officials representing legal institutions that perform investigations, and sometimes too "academic" research, that is conducted at anthropological laboratories, when methods developed are not completely relevant to practical needs. Besides of answering to direct questions (number of individuals, sex, age, stature, population affinity, individual traits, evidence of violence), important humanitarian aspects--the individual's right for identity, the right of the relatives to know the fate of their beloved ones--should not be neglected. Practical use of other identification methods faces difficulties of their own (e.g., odontology--lack of regular dental registration system and compatible database). Two examples of forensic anthropological work of mass graves, even when the results were much influenced by the questions raised by investigators, can serve as an illustration of the above-mentioned issues.

    At the beginning of a new millennium it seems a good idea to stop for a moment and take stock of the current state of forensic science. As a field of scientific research and scientific application, forensic science is a little more than a century old. Forensic science may be said to have begun in 1887 with the simultaneous publication of A. Conan Doyle's A Study in Scarlet and Hans Gross's Handbuch f1/4r Untersuchungsrichter. Conan Doyle's novel introduced to the world the character of Sherlock Holmes, whose literary career would popularize the use of physical evidence in criminal investigations. Gross's manual for examining magistrates suggests ways in which the expertise of chemists, biologists, geologists, and other natural scientists could contribute to investigations. Gross's book was translated into a number of languages and went through various updated editions during the course of the century. The intervening century saw the development and application of fingerprinting, firearm and tool mark identification, forensic chemistry, forensic biology, forensic toxicology, forensic odontology, forensic pathology, and forensic engineering. Increasingly, the judicial systems of the industrial nations of the world have come to rely upon the expertise of scientists in a variety of disciplines. In most advanced countries, virtually all criminal prosecutions now involve the presentation of scientific testimony. This has had the beneficial effect of diminishing the reliance of courts on eyewitness testimony and defendant confessions.

    Full Text Available Cloud computing and digital forensics are emerging fields of technology. Unlike traditional digital forensics where the target environment can be almost completely acquired, isolated and can be under the investigators control; in cloud environments, the distribution of computation and storage poses unique and complex challenges to the investigators.Recently, the term "cloud forensics" has an increasing presence in the field of digital forensics. In this state-of-the-art review, we included the most recent research efforts that used "cloud forensics" as a keyword and then classify the literature in to three dimensions, (1 survey-based, (2 technology-based and (3 forensics procedural-based.We discuss widely accepted international standard bodies and their efforts to cope with the current trend of cloud forensics. Our aim is not only to reference related work based on the discussed dimensions, but also to analyze them and generate a mind map that will help in identifying research gaps. Finally, we summarize existing digital forensics tools and, the available simulation environments that can be used for evidence acquisition, examination and cloud forensics test purposes.

  13. The Police Executive and Governance: Adapting Police Leadership to an Increase in Oversight and Accountability in Police Operations

    2014-03-01

    Full Text Available In a democracy, it is generally understood that the police serve at the will of the people and are accountable through police governance. This usually consists of elected and/or appointed officials whose primary legal authority is to set policy and appoint the police leaders whom they hold accountable for ensuring that effective policing operations are carried out. It is widely held in common law jurisdictions that the governing body is limited in their role and cannot get involved in “operational policing issues.” In June 2010, the G20 world leaders’ conference was held in Toronto, Canada. The events surrounding the police actions during this conference caused a great deal of concern and led the Toronto Police Services Board, who are the governing authority for the Toronto Police Service, to commission a review to look at their own role. The findings in relation to “board” involvement in the operational side of policing challenged a long held belief regarding the limited role of governance in police operations. These findings will be examined in relation to the lack of board expertise and the challenges faced by police leaders to adapt and develop their attitudes, skills and abilities to respond to any expansion of governance authority.

  14. Perceived Threat Associated with Police Officers and Black Men Predicts Support for Policing Policy Reform

    Directory of Open Access Journals (Sweden)

    Allison Louise Skinner

    2016-07-01

    Full Text Available Racial disparities in policing and recent high-profile incidents resulting in the deaths of Black men have ignited a national debate on policing policies. Given evidence that both police officers and Black men may be associated with threat, we examined the impact of perceived threat on support for reformed policing policies. Across three studies we found correlational evidence that perceiving police officers as threatening predicts increased support for reformed policing practices (e.g., limiting the use of lethal force and matching police force demographics to those of the community. In contrast, perceiving Black men as threatening predicted reduced support for policing policy reform. Perceived threat also predicted willingness to sign a petition calling for police reform. Experimental evidence indicated that priming participants to associate Black men with threat could also reduce support for policing policy reform, and this effect was moderated by internal motivation to respond without prejudice. Priming participants to associate police officers with threat did not increase support for policing policy reform. Results indicate that resistance to policing policy reform is associated with perceiving Black men as threatening. Moreover, findings suggest that publicizing racially charged police encounters, which may conjure associations between Black men and threat, could reduce support for policing policy reform.

  15. Forensic Mass Spectrometry

    2015-07-01

    Developments in forensic mass spectrometry tend to follow, rather than lead, the developments in other disciplines. Examples of techniques having forensic potential born independently of forensic applications include ambient ionization, imaging mass spectrometry, isotope ratio mass spectrometry, portable mass spectrometers, and hyphenated chromatography-mass spectrometry instruments, to name a few. Forensic science has the potential to benefit enormously from developments that are funded by other means, if only the infrastructure and personnel existed to adopt, validate, and implement the new technologies into casework. Perhaps one unique area in which forensic science is at the cutting edge is in the area of chemometrics and the determination of likelihood ratios for the evaluation of the weight of evidence. Such statistical techniques have been developed most extensively for ignitable-liquid residue analyses and isotope ratio analysis. This review attempts to capture the trends, motivating forces, and likely impact of developing areas of forensic mass spectrometry, with the caveat that none of this research is likely to have any real impact in the forensic community unless: (a) The instruments developed are turned into robust black boxes with red and green lights for positives and negatives, respectively, or (b) there are PhD graduates in the workforce who can help adopt these sophisticated techniques.

    Full Text Available History of present illness: A 30-year-old male who was brought into the emergency department (ED by police officers after being bitten in the right lower extremity by a police German Shepard after attempting to flee authorities on foot. The patient stated that the dog immediately bit down on his right calf and proceeded to violently shake its head side to side without releasing its grip until police manually pulled the dog off of him. Upon arrival to the ED, he was tachycardic in the 120’s, complaining of severe, throbbing, sharp pain in the right lower extremity, and was neurovascular intact on exam. Significant findings: The photograph is of the anterior compartment of the right lower leg demonstrating multiple deep lacerations with exposed and torn muscle. X-ray showed no foreign body. Discussion: Police dog bites should be treated more cautiously than typical dog bites because these highly-trained dogs are generally larger breeds which are taught to subdue suspects with a bite-and-hold technique rather than bite and release. This can lead to extensive crush injuries, fractures, large caliber lacerations with associated muscle tissue injury and/or severe neurovascular compromise.1 Hence, police dog bites often require provocative diagnostic testing, specialist consultation for possible operative repair, and aggressive irrigation and ultimately admission for intravenous antibiotics.1 This patient’s wound was aggressively irrigated and evaluated by plastic surgery in the ED. He was ultimately admitted for intravenous antibiotics, pain control, wound care, and healing by secondary intention.

    2007-10-25

    Two experiments were performed to test the relevance of bryophyte (Plantae, Bryophyta) material for forensic studies. The first experiment was conducted to reveal if, and how well, plant fragments attach to footwear in general. In the test, 16 persons walked outdoors wearing rubber boots or hiking boots. After 24h of use outdoors the boots were carefully cleaned, and all plant fragments were collected. Afterwards, all plant material was examined to identify the species. In the second experiment, fresh material of nine bryophyte species was kept in a shed in adverse conditions for 18 months, after which DNA was extracted and subjected to genotyping to test the quality of the material. Both experiments give support for the usability of bryophyte material in forensic studies. The bryophyte fragments become attached to shoes, where they remain even after the wearer walks on a dry road for several hours. Bryophyte DNA stays intact, allowing DNA profiling after lengthy periods following detachment from the original plant source. Based on these experiments, and considering the fact that many bryophytes are clonal plants, we propose that bryophytes are among the most usable plants to provide botanical evidence for forensic investigations.

    Full Text Available This article aims at a consistent search of the opinions about the judicial police as one of the subjects, contained in the Albanian criminal procedural law. In article 30 of the Albanian Criminal Procedure Code, are sanctioned the functions, division, addiction and judicial police duties. In the initial phase, the preliminary investigations are the basis of criminal proceedings. This phase includes evidences that cannot be replicated, the security measures are set, it is performed the notice of suit and necessary datas are collected. Searching, tracking, capture and bringing before trial of the perpetrators is considered as one of the oldest activities of human being. The need to ensure these regulations and the aim to prevent the consequences of any criminal activity has forced societies and different states to establish special investigative bodies (investigation and to determine by time their rights and obligations. So judicial police organs were provided and charged with competences and legal responsibility for the detection, crime preventions and research, capturing and bringing before the court, individuals or groups who commit criminal activities. From a comparative overview of legislation of the judicial police in several countries around the world, it is shown that there is no extreme change in structures and organizational patterns of these bodies, missions, powers and responsibilities they exercise (Elezi, 1997, 13.

    Full Text Available Background: Occupational stress and associated physical and mental health related issues are not addressed in Indian police personnel with adequate importance. Methods: Cross-sectional survey was conducted among police personnel (both male and female in Calicut urban police district, Kerala state, India. Police personnel from all designations (ranks, except from the all India services (Indian Police Service were included in the study. Data were collected using a specifically designed datasheet covering socio-demographic profile, physical and mental health related details which was prepared by researchers. Occupational stress was measured using Operational Police Stress Questionnaire (PSQ-OP and Organisational Police Stress Questionnaire (PSQ-ORG. Result: The study found that both operational and organisational stress was significant among the police officers. Organisational stress was experienced in moderate level by 68% and in high level by 14%. Operational stress scores were in the moderate range in 67% and in high range in 16.5%. The younger age group (21-35 years and lower level rank police personnel had higher stress. Stress was higher among female police personnel compared to males. While 23% of them had been diagnosed with physical illnesses, a significant four per cent of them with mental illness, and 29% of them reported substance abuse. Conclusion: The results point to the high level of stress among Indian police personnel and the need for urgent interventions from the government to address the occupational stress.

    1993-01-01

    Being a way of sexual living as old as human history, homosexuality occupies an interesting place in the life of the Turkish people of the Republic of Turkey. This has been so since the days of the glorious Ottoman Empire. In the year 1987, instead of investigating the roots of homosexuality, the pressing need has become to present a particular view of homosexuality in Turkey today. To be more specific, there is a need to explain the problems of Turkish homosexuals and suggest certain vital solutions. Our country is constantly endeavoring to become "westernized" and it is claimed that steps are being taken toward that modernization. Despite this fact, homosexuals are confronted with such great problems that it is not difficult to justify those who say that there is no democracy in Turkey. I will try to explain these problems with documentary evidence and without exaggeration. In doing so, I shall make use of new material in my book, published under the title of Homosexuality in Turkey: Yesterday, Today. Beginning in March of 1986, we compiled a list of the attitudes of the police toward gays, involving pressure and cruelty that can be qualified as torture. Despite this situation, instead of being more democratic and humane, in April 1987 the police force employed terror tactics against homosexuals in Istanbul. This was "the straw that broke the camel's back." Soon after this act of oppression, 18 gays, acting on our suggestions, sued the police for the first time. They then submitted a petition to the Attorney-General and later launched a hunger strike in Taksim Square. These represent movements of importance in the political history of Turkey. From now on homosexuals, too, will have the right to speak out in political affairs.

    In this paper, the importance of modern technology in forensic investigations is discussed. Recent technological developments are creating new possibilities to perform robust scientific measurements and studies outside the controlled laboratory environment. The benefits of real-time, on-site forensic investigations are manifold and such technology has the potential to strongly increase the speed and efficacy of the criminal justice system. However, such benefits are only realized when quality can be guaranteed at all times and findings can be used as forensic evidence in court. At the Netherlands Forensic Institute, innovation efforts are currently undertaken to develop integrated forensic platform solutions that allow for the forensic investigation of human biological traces, the chemical identification of illicit drugs and the study of large amounts of digital evidence. These platforms enable field investigations, yield robust and validated evidence and allow for forensic intelligence and targeted use of expert capacity at the forensic institutes. This technological revolution in forensic science could ultimately lead to a paradigm shift in which a new role of the forensic expert emerges as developer and custodian of integrated forensic platforms. © 2015 The Author(s) Published by the Royal Society.

    2011-12-01

    Forensic entomology is the science of collecting and analysing insect evidence to aid in forensic investigations. Its main application is in the determination of the minimum time since death in cases of suspicious death, either by estimating the age of the oldest necrophagous insects that developed on the corpse, or by analysing the insect species composition on the corpse. In addition, toxicological and molecular examinations of these insects may help reveal the cause of death or even the identity of a victim, by associating a larva with its last meal, for example, in cases where insect evidence is left at a scene after human remains have been deliberately removed. Some fly species can develop not only on corpses but on living bodies too, causing myiasis. Analysis of larvae in such cases can demonstrate the period of neglect of humans or animals. Without the appropriate professional collection of insect evidence, an accurate and convincing presentation of such evidence in court will be hampered or even impossible. The present paper describes the principles and methods of forensic entomology and the optimal techniques for collecting insect evidence.

    This paper reports on an investigation into the skills and competencies of forensic psychiatric nurses from the perspective of three groups: (A) forensic psychiatric nurses; (B) non-forensic psychiatric nurses; and (C) other disciplines. A national survey of forensic psychiatric services in the UK was conducted, and information gathered on the perceived skills and competencies in this growing field of psychiatric practice. From 3360 questionnaires, 1172 were returned, making a response rate of 35%. The results indicate a small discrepancy between forensic nurses' and non-forensic nurses' perceptions of the role constructs of forensic practice. However, a larger difference was noted between nurses' perceptions and other disciplines' perceptions of the constituent parts to forensic psychiatric nursing. Nurses tended to focus on personal qualities both in relation to themselves and the patients, while the other disciplines focused on organizational structures both in defining the role and in the resolution of perceived deficits. The findings have implications for multidisciplinary working, as well as policy formulation and curriculum development in terms of the skills and competencies of forensic nurse training.

    Despite a decade of use in US courtrooms, it is only recently that forensic computer animations have become an increasingly important form of communication in legal spheres within the United Kingdom. Aims Research at the University of Nottingham has been influential in the critical investigation of forensic computer graphics reconstruction methodologies and techniques and in raising the profile of this novel form of data visualization within the United Kingdom. The case study presented demonstrates research undertaken by Aims Research and the Department of Forensic Pathology at the University of Sheffield, which aims to apply, evaluate, and develop novel 3-dimensional computer graphics (CG) visualization and virtual reality (VR) techniques in the presentation and investigation of forensic information concerning the human body. The inclusion of such visualizations within other CG or VR environments may ultimately provide the potential for alternative exploratory directions, processes, and results within forensic pathology investigations.

    Nuclear approaches for compositional characterization has bright application prospect in forensic perspective towards assessment of nature and origin of seized material. The macro and micro physical properties of nuclear materials can be specifically associated with a process or type of nuclear activity. Under the jurisdiction of nuclear analytical chemistry as well as nuclear forensics, thrust areas of scientific endeavor like determination of radioisotopes, isotopic and mass ratios, analysis for impurity contents, arriving at chemical forms/species and physical parameters play supporting evidence in forensic investigations. The analytical methods developed for this purposes can be used in international safeguards as well for nuclear forensics. Nuclear material seized in nuclear trafficking can be identified and a profile of the nuclear material can be created

    Forensic anthropology is playing an increasingly important role facing violence and impunity in many countries. A research performed at police stations of Civil Police and Forensic Institutes of six Brazilian capitals demonstrated that the practice of recover and positive identification of human remains has been neglected in different levels. The main problem is the lack of specific training of the professionals that accomplish the expertise in field and laboratory, but also the fact that no anthropological database of disappeared people is available. As a result of this situation, an expressive number of human remains leave the forensic institutes without positive identification, and criminal inquiries of homicides stay without resolution, contributing to the aggravation of the violence and impunity scenery that devastates the country.

  19. An investigation of red fox (Vulpes vulpes) and Eurasian badger (Meles meles) scavenging, scattering, and removal of deer remains: forensic implications and applications.

    Within northwest Europe, especially the United Kingdom, the red fox (Vulpes vulpes) and the Eurasian Badger (Meles meles) are the largest wild scavengers capable of modifying a set of remains through scavenging. Knowledge of region-specific and species-typical scavenging behaviors of scavengers within the crime scene area and surroundings can aid in more efficient and accurate interpretations. The scavenging behaviors of captive and wild foxes and badgers were recorded and compared through actualistic methods and direct observation. The scavenging by wild foxes and badgers of surface-deposited baits and whole deer (Cervus nippon; Capreolus capreolus) in a woodland was observed and analyzed. Wild foxes were found to scavenge deer more frequently than badgers. The scavenging of deer remains by foxes was also compared with forensic cases. The scavenging pattern and recovery distances of deer and human remains scavenged by foxes were similar but were potentially affected by the condition and deposition of a body, and the presence of clothing. © 2014 American Academy of Forensic Sciences.

    There are forensic inquiries in which an identification of epithelial cell types would provide important probative evidence. In cancer diagnosis, this information is yielded by histological examination of cytokeratin (Ck). Therefore, we tested 19 antibodies against different Cks (Ck1, Ck2e, Ck4, Ck5-6, Ck7, Ck8, Ck9, CK10, Ck13, Ck14, Ck15, Ck16, Ck17, Ck18, Ck19, Ck20, Ck903, PanCkAE1_3, and CAM5-2) on histological sections of epidermis, buccal mucosa, vaginal mucosa, penis, urogenital tract, and rectum and could identify two antigens unique to buccal-cell and vaginal-cell (Ck4) and skin epithelial-cell (Ck10) cytokeratin. Subsequently, we developed an immunocytological technique for distinguishing swabbed skin and mucosal cells up to at least 1 year after sampling. By the detection of the Ck4 and Ck10 mRNAs in biopsy and laser capture microdissection collected samples via quantitative real-time polymerase chain reaction, we were able to confirm our immunological findings. Hence, this study offers techniques to discriminate between skin and mucosal cells (buccal and vaginal) in forensic casework.

    Nuclear forensics are the technical means by which nuclear and other radioactive materials used in illegal activities are characterized as to physical and chemical condition, provenance, and history. Sampling for traditional forensics evidence (e.g. fingerprints, DNA, hair, fibers, and digital evidence) contaminated by radionuclides, and categorization of nuclear and other radioactive materials by on-sight measurement are required for first responders. Portable radiological equipment and radiation protection for first responders to achieve emergency tasks safely at the incident sites have been developed and evaluated in National Research Institute of Police Science. In this report, we introduce wireless network dosimetry system and neutron protection shield with water under sampling and categorization. Described next in this report are evaluation tests of active personal dosimeters using neutron irradiation field in Pacific Northwest National Laboratory. We evaluated them under fast and thermal neutron field. We confirmed the large fluctuation of the response for each dosimeter caused by the energy dependence of the detectors. (author)

  2. Computer Forensics Field Triage Process Model

    Marcus K. Rogers

    2006-06-01

    Full Text Available With the proliferation of digital based evidence, the need for the timely identification, analysis and interpretation of digital evidence is becoming more crucial. In many investigations critical information is required while at the scene or within a short period of time - measured in hours as opposed to days. The traditional cyber forensics approach of seizing a system(s/media, transporting it to the lab, making a forensic image(s, and then searching the entire system for potential evidence, is no longer appropriate in some circumstances. In cases such as child abductions, pedophiles, missing or exploited persons, time is of the essence. In these types of cases, investigators dealing with the suspect or crime scene need investigative leads quickly; in some cases it is the difference between life and death for the victim(s. The Cyber Forensic Field Triage Process Model (CFFTPM proposes an onsite or field approach for providing the identification, analysis and interpretation of digital evidence in a short time frame, without the requirement of having to take the system(s/media back to the lab for an in-depth examination or acquiring a complete forensic image(s. The proposed model adheres to commonly held forensic principles, and does not negate the ability that once the initial field triage is concluded, the system(s/storage media be transported back to a lab environment for a more thorough examination and analysis. The CFFTPM has been successfully used in various real world cases, and its investigative importance and pragmatic approach has been amply demonstrated. Furthermore, the derived evidence from these cases has not been challenged in the court proceedings where it has been introduced. The current article describes the CFFTPM in detail, discusses the model’s forensic soundness, investigative support capabilities and practical considerations.

    This study investigated the influence of stress appraisal and coping on work engagement levels (Absorption, Vigour, and Dedication) of police recruits. Participants were 387 men, ages 20 to 33 yr. (M = 24.1, SD = 2.4), in their last month of academy training before becoming police officers. Partially in support of predictions, work engagement was associated with Stressor control perceived, but not Stress intensity experienced over a self-selected stressor. Although the three dimensions of work engagement were explained by Stressor control and coping, Absorption was the dimension better explained by these variables. Police recruits reporting higher Absorption, Vigour, and Dedication reported using more Active coping and less Behavioural disengagement. Results showed that stress appraisal and coping are important variables influencing work engagement among police recruits. Findings suggested that future applied interventions fostering work engagement among police recruits should reinforce perceptions of control over a stressor as well as Active coping strategies.

  7. Extraction of DNA from Forensic Biological Samples for Genotyping.

    2010-07-01

    Biological forensic samples constitute evidence with probative organic matter. Evidence believed to contain DNA is typically processed for extraction and purification of its nucleic acid content. Forensic DNA samples are composed of two things, a tissue and the substrate it resides on. Compositionally, a sample may contain almost anything and for each, the type, integrity, and content of both tissue and substrate will vary, as will the contaminant levels. This fact makes the success of extraction one of the most unpredictable steps in genotypic analysis. The development of robust genotyping systems and analysis platforms for short tandem repeat (STR) and mitochondrial DNA sequencing and the acceptance of results generated by these methods in the court system, resulted in a high demand for DNA testing. The increasing variety of sample submissions created a need to isolate DNA from forensic samples that may be compromised or contain low levels of biological material. In the past decade, several robust chemistries and isolation methods have been developed to safely and reliably recover DNA from a wide array of sample types in high yield and free of PCR inhibitors. In addition, high-throughput automated workflows have been developed to meet the demand for processing increasing numbers of samples. This review summarizes a number of the most widely adopted methods and the best practices for DNA isolation from forensic biological samples, including manual, semiautomated, and fully automated platforms.

  8. The View from Inside the System: How Police Explain Their Response to Sexual Assault.

    Science.gov (United States)

    Shaw, Jessica; Campbell, Rebecca; Cain, Debi

    2016-12-01

    Prior research has documented the problematic community response to sexual assault: the majority of sexual assaults reported to police are never prosecuted. Social dominance theory suggests that this response is a form of institutional discrimination, intended to maintain existing social structures, and that police personnel likely draw upon shared ideologies to justify their decision-making in sexual assault case investigations. This study drew upon social dominance theory to examine how police justified their investigatory decisions to identify potential leverage points for change. The study revealed that the likelihood of a case referral to the prosecutor increased with each additional investigative step completed; of the different types of justifications provided by police for a less-than-thorough investigative response and stalled case, blaming the victim for the poor police investigation proved to be the most damaging to case progression; and the type of explanation provided by police was impacted by specific case variables. As suggested by social dominance theory, the study demonstrates that police rely on several different mechanisms to justify their response to sexual assault; implementing criminal justice system policies that target and interrupt these mechanisms has the potential to improve this response, regardless of specific case factors. © Society for Community Research and Action 2016.

    Mental disorders are among the most prevalent of chronic disorders, and a high prevalence of these disorders has been consistently found in jails and prisons. This study was a retrospective case series that described the population of adults charged with a criminal offense who were court ordered to undergo a psychiatric assessment within the Medical Legal Service in Santiago, Chile from 2005 to 2006. Characteristics were explored in order to better understand this population in light of the recent reforms in the judicial and health systems of Chile. Ninety percent of sampled individuals were male, primarily between the ages of 18-39 years. Seventy percent of the evaluations came from the pre-reformed judicial system and 30% were from the reformed system. Approximately 63% of evaluated offenders were considered to have a psychiatric pathology, the most common being the personality disorders. Of the evaluated offenders, approximately 84% were considered by a psychiatrist to be criminally responsible for their crime, 7% were regarded as having diminished criminal responsibility, 4% were considered to be not criminally responsible for their crime, and 4% were cases where criminal responsibility was not applicable. Profession status, municipality of residence, type of residence, ICD-10 diagnosis, treatment recommendation, and criminal responsibility were found to be significantly different between male and female evaluated offenders. Results from this investigation will contribute to knowledge about forensic psychiatry and mental health in Latin America, and will hopefully pave the way for more research and international comparisons.

  11. Testing Framework for Mobile Device Forensics Tools

    Directory of Open Access Journals (Sweden)

    Maxwell Anobah

    2014-09-01

    Full Text Available The proliferation of mobile communication and computing devices, in particular smart mobile phones, is almost paralleled with the increasing number of mobile device forensics tools in the market. Each mobile forensics tool vendor, on one hand claims to have a tool that is best in terms of performance, while on the other hand each tool vendor seems to be using different standards for testing their tools and thereby defining what support means differently. To overcome this problem, a testing framework based on a series of tests ranging from basic forensics tasks such as file system reconstruction up to more complex ones countering antiforensic techniques is proposed. The framework, which is an extension of an existing effort done in 2010, prescribes a method to clearly circumscribe the term support into precise levels. It also gives an idea of the standard to be developed and accepted by the forensic community that will make it easier for forensics investigators to quickly select the most appropriate tool for a particular mobile device.

    Gomes, Leonardo; Von Zuben, Cláudio J

    2006-01-01

    Apart from an early case report from China (13th century), the first observations on insects and other arthropods as forensic indicators were documented in Germany and France during mass exhumations in the 1880s by Reinhard, who is considered a co-founder of the discipline. After the French publication of Mégnin's popular book on the applied aspects of forensic entomology, the concept quickly spread to Canada and United States. At that time, researchers recognized that the lack of systematic observations of insects of forensic importance jeopardized their use as indicators of postmortem interval. General advances in insect taxonomy and ecology helped to fill this gap over the following decades. After World Wars, few forensic entomology cases were reported in the scientific literature. From 1960s to the 1980s, Leclercq and Nuorteva were primarily responsible for maintaining the method in Central Europe, reporting isolated cases. Since then, basic research in the USA, Russia and Canada opened the way to the routine use of Entomology in forensic investigations. Identifications of insects associated with human cadavers are relatively few in the literature of the Neotropical region and have received little attention in Brazil. This article brings an overview of historic developments in this field, the recent studies and the main problems and challenges in South America and mainly in Brazil.

  17. Lies and coercion: why psychiatrists should not participate in police and intelligence interrogations.

    Science.gov (United States)

    Janofsky, Jeffrey S

    2006-01-01

    Police interrogators routinely use deceptive techniques to obtain confessions from criminal suspects. The United States Executive Branch has attempted to justify coercive interrogation techniques in which physical or mental pain and suffering may be used during intelligence interrogations of persons labeled unlawful combatants. It may be appropriate for law enforcement, military, or intelligence personnel who are not physicians to use such techniques. However, forensic psychiatry ethical practice requires honesty, striving for objectivity, and respect for persons. Deceptive and coercive interrogation techniques violate these moral values. When a psychiatrist directly uses, works with others who use, or trains others to use deceptive or coercive techniques to obtain information in police, military, or intelligence interrogations, the psychiatrist breaches basic principles of ethics.

    2016-09-01

    The rise of forensic pathology in human medicine has greatly contributed to the administration of justice, public safety and security, and medical knowledge. However, the evolution of human forensic pathology has been challenging. Veterinary forensic pathologists can learn from some of the lessons that have informed the growth and development of human forensic pathology. Three main observations have emerged in the past decade. First, wrongful convictions tell us to use a truth-seeking stance rather than an a priori "think dirty" stance when investigating obscure death. Second, missed homicides and concealed homicides tell us that training and certification are the beginning of reliable forensic pathology. Third, failure of a sustainable institutional arrangement that fosters a combination of service, research, and teaching will lead to stagnation of knowledge. Forensic pathology of humans and animals will flourish, help protect society, and support justice if we embrace a modern biomedical scientific model for our practice. We must build training programs, contribute to the published literature, and forge strong collaborative institutions. © The Author(s) 2016.

    Singapore is a geographically small nation-state that has transformed itself from a third-world country to a developed nation after attaining political independence 46 years ago. The pace of change has been tremendous and mental health care is no exception. This paper provides an overview of mental health care and a review of key mental health legislation, including a National Mental Health Blueprint that was rolled out in 2007. On this background, the paper focuses on a description of forensic psychiatric services in Singapore. The role of the Department of Forensic Psychiatry at the Institute of Mental Health, which is the only forensic psychiatry department in the country, will be highlighted. Civil commitment and the treatment of unfit accused persons and insanity acquittees is reviewed. The role of forensic psychiatric assessments in the Singapore courts is examined. The application of the insanity and diminished responsibility defenses are reviewed. A trend is identified in the Singapore courts towards a more rehabilitation-focused sentencing approach and the role that forensic psychiatric assessments play in cases involving mentally disordered offenders is highlighted.

Methods sociological absentee polling in the form of a questionnaire statistical logical documentary graphic method of systemic analysis. Results the opinions of the population on police are extremely controversial. It is connected mostly with the sources of information which mostly are not reliable and objective. The article shows that despite the growth of victimization the level of anxiety of the population about the criminal attacks is gradually reduced and the sense of security in citizens is strengthened though often due to their personal efforts to protect their life health and property. Only every fifth citizen relies on the participation of law enforcers in ensuring security and public order. The survey revealed that about half of the citizens who are potentially interested in the reaction of law enforcement officers to the crime actually agree to leave the offender unpunished due to the mistrust of the police. A third of claimants were unsatisfied with the police action on their application which does not correlate with the declared numbers. The opinion of Volgograd citizens on the frequency of bribery among police officers remains unchanged whereas other malfeasances received a significant increase. And despite this the attitude of the respondents towards the police in general has improved. Mostly it was the result of media activities that inform the public about successful police work using TV shows documentaries and feature films. The successful work of the police is also confirmed by statistic that shows the rapid decline in recorded crime. Scientific novelty for the first time on the basis of a combination of various methods the reliability and objectivity of information to the population is investigated on the police of Volgograd oblast.

    In the context of a public health-oriented drug policy reform in Mexico, we assessed the spatial distribution of police encounters among people who inject drugs (PWID) in Tijuana, determined the association between these encounters and the location of addiction treatment centers and explored the association between police encounters and treatment access. Geographically weighted regression (GWR) and logistic regression analysis using prospective spatial data from a community-recruited cohort of PWID in Tijuana and official geographical arrest data from the Tijuana Municipal Police Department. Tijuana, Mexico. A total of 608 participants (median age 37; 28.4% female) in the prospective Proyecto El Cuete cohort study recruited between January and December 2011. We compared the mean distance of police encounters and a randomly distributed set of events to treatment centers. GWR was undertaken to model the spatial relationship between police interactions and treatment centers. Logistic regression analysis was used to investigate factors associated with reporting police interactions. During the study period, 27.5% of police encounters occurred within 500 m of treatment centers. The GWR model suggested spatial correlation between encounters and treatment centers (global R(2)  = 0.53). Reporting a need for addiction treatment was associated with reporting arrest and police assault [adjusted odds ratio = 2.74, 95% confidence interval (CI) = 1.25-6.02, P = 0.012]. A geospatial analysis suggests that, in Mexico, people who inject drugs are at greater risk of being a victim of police violence if they consider themselves in need of addiction treatment, and their interactions with police appear to be more frequent around treatment centers. © 2016 Society for the Study of Addiction.

    Full Text Available This paper presents a real case of digital forensic analysis in organizational fraud auditing process investigated using two different forensic tools, namely Tableau TD3 Touch Screen Forensic Imager and Access Data FTK Imager. Fraud auditing is more of a mindset than a methodology and has different approaches from financial auditing. Fraud auditors are mostly focused on exceptions, accounting irregularities, and patterns of their conduct. Financial auditors place special emphasis on the audit trail and material misstatements. A fraud case investigation of non-cash misappropriations committed by an employee, the warehouseman, will be presented herein in order to highlight the usefulness of fraud auditing, which can reveal many forms of financial crime and can be used in both private and public sector companies. Due to the computerized accounting environment, fraud investigation requires a combination of auditing, computer crime and digital forensic investigation skills, which can be achieved through joint efforts and cooperation of both digital investigator and fraud auditor as proposed herein.

  5. A CONCEPT FOR NATIONAL NUCLEAR FORENSIC LIBRARIES

    International Nuclear Information System (INIS)

    Wacker, John F.; Curry, Michael

    2010-01-01

    The interpretation of data from the nuclear forensic analysis of illicit nuclear material of unknown origin requires comparative data from samples of known origin. One way to provide such comparative data is to create a system of national nuclear forensics libraries, in which each participating country stores information about nuclear or other radioactive material that either resides in or was manufactured by that country. Such national libraries could provide an authoritative record of the material located in or produced by a particular country, and thus forms an essential prerequisite for a government to investigate illicit uses of nuclear or other radioactive material within its borders. We describe the concept of the national nuclear forensic library, recommendations for content and structure, and suggested querying methods for utilizing the information for addressing nuclear smuggling.

Similar to the Olympic motto of ‘faster, higher, stronger’, forensic DNA protocols can be expected to become more rapid and sensitive and provide stronger investigative potential. New short tandem repeat (STR) loci have expanded the core set of genetic markers used for human identification in Europe and the USA. Rapid DNA testing is on the verge of enabling new applications. Next-generation sequencing has the potential to provide greater depth of coverage for information on STR alleles. Familial DNA searching has expanded capabilities of DNA databases in parts of the world where it is allowed. Challenges and opportunities that will impact the future of forensic DNA are explored including the need for education and training to improve interpretation of complex DNA profiles. PMID:26101278

    2014-01-01

    The challenge in achieving an ideal state of justice is that each "proof" has the highest degree of reliability. This is the main responsibility of the forensic scientist. Up to now, criminal investigations in Mexico have been supported by forensic work from a wide variety of disciplinary backgrounds that give testimony in a particular area, even though they may have become forensic witnesses in a complementary and experiential manner. In January 2013, the Universidad Nacional Autónoma de México (UNAM) approved the "Forensic Science" undergraduate program that, in collaboration with various academic entities and government institutions, will develop forensic scientists trained in science, law, and criminology. This is focused on contributing to the national demand that the justice system has more elements to procure and administer justice in dealing with crime.

  11. Cognitive neuroscience in forensic science: understanding and utilizing the human element.

    Science.gov (United States)

    Dror, Itiel E

    2015-08-05

    The human element plays a critical role in forensic science. It is not limited only to issues relating to forensic decision-making, such as bias, but also relates to most aspects of forensic work (some of which even take place before a crime is ever committed or long after the verification of the forensic conclusion). In this paper, I explicate many aspects of forensic work that involve the human element and therefore show the relevance (and potential contribution) of cognitive neuroscience to forensic science. The 10 aspects covered in this paper are proactive forensic science, selection during recruitment, training, crime scene investigation, forensic decision-making, verification and conflict resolution, reporting, the role of the forensic examiner, presentation in court and judicial decisions. As the forensic community is taking on the challenges introduced by the realization that the human element is critical for forensic work, new opportunities emerge that allow for considerable improvement and enhancement of the forensic science endeavour. © 2015 The Author(s) Published by the Royal Society.

    Full Text Available Objective: In this study it is aimed to examine forensic food poisoning cases and to evaluate the clinical presentation of food poisoning in people within the context of forensic medicine. Methods: In the study, 215 food poisoning cases are evaluated, which applied to the forensic medicine branch office in our city between 01.01.2007 and 31.12.2011. The forensic reports and forensic investigations of these cases are analyzed retrospectively. The cases are examined in terms of gender, age, the type of food consumed, the treatment applied and the result of the forensic report. Results: It is determined that in 83 cases (38.6% food poisoning was caused by chicken products, and in 178 cases (82.8% the poisoned people were students. In 3 cases (1.4% the poisoning was life threatening. For 75 cases (34.9% no forensic report was prepared in emergency service and among the 140 cases for which a forensic report was prepared, only 3 of the reports were prepared in a correct manner. Conclusions: It is determined that the demographic data of the cases complies with the city where the study was conducted. It is found out that in emergency services the food poisoning cases are usually misevaluated.

    2014-05-01

    Wildlife forensic science may not have attained the profile of human identification, yet the scale of criminal activity related to wildlife is extensive by any measure. Service delivery in the arena of wildlife forensic science is often ad hoc, unco-ordinated and unregulated, yet many of those currently dedicated to wildlife conservation and the protection of endangered species are striving to ensure that the highest standards are met. The genetic markers and software used to evaluate data in wildlife forensic science are more varied than those in human forensic identification and are rarely standardised between species. The time and resources required to characterise and validate each genetic maker is considerable and in some cases prohibitive. Further, issues are regularly encountered in the construction of allelic databases and allelic ladders; essential in human identification studies, but also applicable to wildlife criminal investigations. Accreditation and certification are essential in human identification and are currently being strived for in the forensic wildlife community. Examples are provided as to how best practice can be demonstrated in all areas of wildlife crime analysis and ensure that this field of forensic science gains and maintains the respect it deserves. This review is aimed at those conducting human identification to illustrate how research concepts in wildlife forensic science can be used in the criminal justice system, as well as describing the real importance of this type of forensic analysis.

    2011-01-01

    In a strange turn of history, the threat of global nuclear war has gone down, but the risk of a nuclear attack has gone up. The danger of nuclear terrorism and ways to thwart it, tackle it and manage it in the event of an attack is increasingly gaining the attention of nuclear analysts all over the world. There is rising awareness among nuclear experts to develop mechanisms to prevent, deter and deal with the threat of nuclear terrorism. Nuclear specialists are seeking to develop and improve the science of nuclear forensics so as to provide faster analysis during a crisis. Nuclear forensics can play an important role in detecting illicit nuclear materials to counter trafficking in nuclear and radiological materials. An effective nuclear forensic and attribution strategy can enable policy makers, decision makers and technical managers to respond to situations involving interception of special nuclear materials

    2000-09-01

    Autopsy numbers in Australian hospitals have declined markedly during the past decade despite evidence of a relatively static rate of demonstrable clinical misdiagnosis during this time. The reason for this decrease in autopsy numbers is multifactorial and may include a general lack of clinical and pathologic interest in the autopsy with a possible decline in autopsy standard, a lack of clinicopathologic correlation after autopsies, and an increased emphasis on surgical biopsy reporting within hospital pathology departments. Although forensic autopsies are currently maintaining their numbers, it is incumbent on forensic pathologists to demonstrate the wealth of important information a carefully performed postmortem examination can reveal. To this end, the Pathology Division of the Victorian Institute of Forensic Medicine has instituted a program of minimum standards in varied types of coroner cases and commenced a system of internal and external audit. The minimum standard for a routine, sudden, presumed natural death is presented and the audit system is discussed.

    An adequate death investigation requires the combined efforts and cooperation of experts in different disciplines: crime scene technicians, death investigators, forensic pathologists, anthropologists, entomologists, other medical and non-medical professionals. These front-line experts play a crucial role in every death investigation process. The forensic pathologist normally has the legal authority to take charge of the dead body at a death scene and his primary functions are the exterior and interior examination of the cadaver by analyzing the extent of antemortem injuries and the postmortem changes and the recovery of physical evidence. He is responsible for determining how, when and why of any death which is the result of violence, suspicious or unexplained circumstances or a death which is sudden or unattended, defending and explaining the reasons for making these diagnoses in a courtroom. The forensic entomologist can provide invaluable aid in death cases where human remains are colonized by insects and in the overall investigation. His principal role is to identify the arthropods associated with such cases and to analyze entomological data for interpreting insect evidence. He is responsible for determining the period of insect activity according to all the variables affecting insect invasion of remains and their development. The major goal of medico-criminal entomology is to contribute to the determination of the time, cause, manner and place of the investigated death (especially on badly decomposed corpses or skeletonized human remains) with the support of all the elements which can be inferred from the study of insects found on the cadaver or nearby. The application of techniques devised recently in forensic entomology can allow experts in the field to collect strong entomological evidence and provide useful information not only in a death investigation including movement or storage of the remains following death, time of dismemberment, postmortem artifacts

    The spread of navigation devices has increased significantly over the last 10 years. With the help of the current development of even smaller navigation receiver units it is to navigate with almost any current smart phone. Modern navigation systems are no longer limited to satellite navigation, but use current techniques, e.g. WLAN localization. Due to the increased use of navigation devices their relevance to forensic investigations has risen rapidly. Because navigation, for example with navigation equipment and smartphones, have become common place these days, also the amount of saved navigation data has risen rapidly. All of these developments lead to a necessary forensic analysis of these devices. However, there are very few current procedures for investigating of navigation devices. Navigation data is forensically interesting because by the position of the devices in most cases the location and the traveled path of the owner can be reconstructed. In this work practices for forensic analysis of navigation devices are developed. Different devices will be analyzed and it is attempted, by means of forensic procedures to restore the traveled path of the mobile device. For analysis of the various devices different software and hardware is used. There will be presented common procedures for securing and testing of mobile devices. Further there will be represented the specials in the investigation of each device. The different classes considered are GPS handhelds, mobile navigation devices and smartphones. It will be attempted, wherever possible, to read all data of the device. The aim is to restore complete histories of the navigation data and to forensically study and analyze these data. This is realized by the usage of current forensic software e.g. TomTology or Oxygen Forensic Suite. It is also attempted to use free software whenever possible. Further alternative methods are used (e.g. rooting) to access locked data of the unit. To limit the practical work the

  1. Understanding Revenge Pornography: A National Survey of Police Officers and Staff in England and Wales.

    2018-02-01

    Online abuse, facilitated via social media and mobile technologies, has recently attracted considerable academic attention. The nonconsensual sharing of intimate images-revenge pornography-can have a devastating effect on victims, is a global problem, and constitutes interpersonal violence. The national helpline in the United Kingdom has now received over 7,000 calls. In the United Kingdom, new legislation making revenge pornography a crime was introduced in 2014, yet the police do not always respond appropriately to victims. This article presents the findings of a national online survey of police understanding of revenge pornography, undertaken in the United Kingdom in March 2017. The study set out to investigate police knowledge of revenge pornography legislation, their confidence in responding to cases of revenge pornography, and what level of training they had received. A total of 783 members of the police force responded to the survey and, to the authors' knowledge, this the first study to seek to quantify the understanding of revenge pornography by police officers and staff in England and Wales. The findings suggest that the police in the United Kingdom have a limited understanding of revenge pornography legislation and lack confidence both in investigating cases and in effectively responding to victims. The implications of the study demonstrate that there is an urgent need for training across police forces to ensure that cases of revenge pornography are appropriately responded to, victims are safeguarded, and offenders brought to justice.

    Nuclear forensics corresponds to the forensic analysis of nuclear materials. The samples analysed may either be those that are confiscated during any act of smuggling or that is retrieved from a postexplosion debris. The characterisation of the material is based on the isotopic composition, physical and chemical compositions, age and history of the material which are determined by suitable analytical techniques. The interpretation of the analytical results is necessary to understand the details of the material such as its provenance, the industrial history of the material as well as the implications of the probable use of the material

    Full Text Available The principal objective of the study was to determine the personality profile of police recruits who are high on anxiety. A secondary objective was to determine whether there are gender and ethnic differences in the levels of anxiety of those police recruits. To investigate the stated objectives the NEO Personality Inventory, Locus of Control Inventory and the IPAT Anxiety Scale were applied to 487 police recruits. Complete records were obtained for 259 participants. In comparing the personality profiles of participants who are high on anxiety and those who are low, it turned out that the biggest differences were in respect of Neuroticism, External Locus of Control and Agreeableness.

    Full Text Available This paper investigates whether, and if so, how procedural fairness affects performance evaluation system satisfaction in a UK Police Force. Employing a survey method with samples of detective inspectors and detective chief inspectors with significant managerial responsibilities in a UK Police Force, this study finds that procedural fairness affects performance evaluation system satisfaction. Further analysis reveals that the effect of procedural fairness on performance evaluation system satisfaction is mediated by trust. This study provides empirical evidence on how procedural fairness affects performance evaluation system satisfaction. The results of this study may benefit the designer of performance evaluation systems in police organizations.

  12. Food Policing in Early Modern Danish Towns

    Directory of Open Access Journals (Sweden)

    Jørgen Mührmann-Lund

    2016-08-01

    Full Text Available This article explores the efforts of early modern authorities to provide food security in three different Danish towns in order to understand the goals and methods of early modern food policing. As in other European countries, urban authorities were expected as part of the regulation called ‘the police’ to control the guilds and fix the prices on bread, meat, beer and other life necessities in order to avoid scarcity among the urban poor. In 1682–83 the Danish king established a police force in Copenhagen and the other market towns. The goal of the metropolitan police was to increase the population of the capital and thus increase the military-fiscal power of the absolutist state, by providing food security and even a comfortable life. In practice, the vigilant policing of bakers, butchers and brewers proved difficult. The positive economic effect of food policing was doubted early on and was reduced as a means to avoid food riots at the end the 18th century. In a major provincial market town like Aalborg, the food trade was policed in a similar manner by the town council and the police, but especially the intermediate trade proved difficult to stop. In a tiny, agrarian market town like Sæby, food policing was more a question of feeding the poor with the town’s own products.

    Directory of Open Access Journals (Sweden)

    Suve Priit

    2015-06-01

    Full Text Available In this article we analyse professional police and community policing in view of professionalism, strategy and structures. We aim to find ways for synthesizing these models that are usually seen as incompatible. Unlike many earlier studies of police organizations or strategies, we view strategies in the organization at the corporate, functional and operational levels, and argue that by combining them with functional and divisional principles of structuring, it is possible to place professional strategy at the core of policing, while using the community policing strategy mainly as a component part of the strategy in the framework of divisional organization. This way it is possible to avoid the risk of alienating police from the community and to ensure the successful implementation of corporate strategy through providing professional police units that perform the narrow functions, with quick and adequate information from the community.

  18. Police use of handcuffs in the homeless population leads to long-term negative attitudes within this group.

    Science.gov (United States)

    Krameddine, Yasmeen I; Silverstone, Peter H

    2016-01-01

    The police interact with homeless individuals frequently. However, there has been relatively little research on the attitudes of homeless individuals towards the police, and how police interactions may impact these. This is important since the attitudes of homeless individuals can impact how often they report crimes, and how well they support police when they are investigating crimes in this population. We interviewed 213 homeless individuals in a single city, representing approximately 10% of the total homeless population. They were interviewed at either homeless shelters, or events held specifically for the homeless population. Of these individuals, 75% were male, and 47% had interacted with a police officer within the past month. Self-reports suggested that 60% had a drug and/or alcohol issue and 78% had a mental illness. We found a highly statistically significant difference between the group that had been handcuffed and/or arrested compared to those that had not. This was across multiple domains and included how the individual regarded the police in terms of their empathy and communication skills, and how much they trusted the police. These changes were long-term, and if a homeless individual had been arrested or handcuffed (and verbal reporting suggested that being handcuffed was the by far the most important factor) then these negative attitudes lasted at least 2 years. The primary conclusion from this study is that when police handcuff a homeless individual, this can lead to long-term negative views about the police across several domains that appear to be long lasting, and were linked to feelings of not being respected by the police. It is therefore proposed that police officers should be made aware of the potential long-term negative consequences of this single action, and that police forces should consider providing specific training to minimize any unnecessary overuse of handcuffs.

    Kubiak, Jeanette; Krick, Annika; Egloff, Boris

    2017-09-01

    Vigilant coping is characterized by a deep processing of threat-related information. In many cases, vigilant coping increases stress symptoms, whereas avoidant coping decreases negative affect. However, vigilance may be beneficial when stress-eliciting situations involve a risk of injury or escalation as is usually the case in police operations. We investigated the roles of vigilance and cognitive avoidance in police operations in a cross-sectional survey. The participants were 137 students (104 men, M age  = 28.54, SD = 8.04) from the Federal University of Applied Administrative Sciences; 76 of them were already police officers (work experience: M = 12.59 years), and 61 were police officer candidates who had completed a 3- to 6-month police internship. Participants completed a paper-and-pencil survey and reported their operational stress, dispositional vigilance and cognitive avoidance in police operations, and stress symptoms. We found that vigilance was negatively associated with stress symptoms and moderated the relationship between operational stress and stress symptoms. Cognitive avoidance, on the other hand, just missed the level of statistical significance in our test of whether it was positively associated with stress symptoms. Our findings demonstrate that vigilance may protect against the negative consequences of stress in police operations.

    When human remains are found, the priority of the investigation is to ascertain the identity of the deceased. A positive identification is a key factor in providing closure for the family of the deceased; it is also required to issue the death certificate and therefore, to settle legal affairs. Moreover, it is difficult for any forensic investigation involving human remains to be solved without the determination of an identity. Therefore, personal identification is necessary for social, legal and forensic reasons. In the last thirty years forensic odontology has experienced an important transformation, from primarily involving occasional dental identification into a broader role, contributing to the determination of the biological profile. In the same way, "DNA fingerprinting" has evolved not only in terms of improving its technology, but also in its application beyond the "classical": helping with the estimation of sex, age and ancestry. As these two forensic disciplines have developed independently, their pathways have crossed several times through human identification operations, especially the ones that require a multidisciplinary approach. Thus, the aim of this review is to describe the contributions of both forensic odontology and molecular biology/biochemistry to human identification, demonstrating how a multidisciplinary approach can lead to a better and more efficient identification.

    The international community has recognized the serious threat posed by nuclear and other radioactive material out of regulatory control. To address these concerns, the Office of Nuclear Security of the international Atomic Energy Agency (IAEA) is developing, inter alia, guidance for nuclear forensics to assist Member States. According to the IAEA Incident and Trafficking Database (ITDB) of the IAEA to record the illegal trade and trafficking incidents of nuclear material or other radioactive material, incidents of 2331 have been reported in 1993 to 2012. These incidents mean that we are not safe for nuclear material. In order to solve the case generated by the illicit trafficking of nuclear material and the efficient management of nuclear material, the study of nuclear forensics is very important. In this study, we investigated the analytical techniques and the current status of nuclear forensics research. In this study, we investigated the current status of research of nuclear forensics, procedures for analysis and nuclear forensics analysis technique. A result of the study, we have been found that the major institutes and laboratory actively research on analysis technique and nuclear forensics. However, research on nuclear forensics is still in early stage, ROK is necessary preliminary survey of analysis technique and foundation of physical, chemical, and morphology characteristics of nuclear materials

    The examination of skeletal remains is a challenge to the medical examiner's/coroner's office and the forensic anthropologist conducting the investigation. One of the objectives of the medico-legal investigation is to estimate stature or height from various skeletal remains and body parts brought for examination. Various skeletal remains and body parts bear a positive and linear correlation with stature and have been successfully used for stature estimation. This concept is utilized in estimation of stature in forensic anthropology casework in mass disasters and other forensic examinations. Scientists have long been involved in standardizing the anthropological data with respect to various populations of the world. This review deals with some essential methodological issues that need to be addressed in research related to estimation of stature in forensic examinations. These issues have direct relevance in the identification of commingled or unknown remains and therefore it is essential that forensic nurses are familiar with the theories and techniques used in forensic anthropology. © 2012 International Association of Forensic Nurses.

    Computer-generated three-dimensional (3D) animation is an ideal media to accurately visualize crime or accident scenes to the viewers and in the courtrooms. Based upon factual data, forensic animations can reproduce the scene and demonstrate the activity at various points in time. The use of computer animation techniques to reconstruct crime scenes is beginning to replace the traditional illustrations, photographs, and verbal descriptions, and is becoming popular in today's forensics. This article integrates work in the areas of 3D graphics, computer vision, motion tracking, natural language processing, and forensic computing, to investigate the state-of-the-art in forensic visualization. It identifies and reviews areas where new applications of 3D digital technologies and artificial intelligence could be used to enhance particular phases of forensic visualization to create 3D models and animations automatically and quickly. Having discussed the relationships between major crime types and level-of-detail in corresponding forensic animations, we recognized that high level-of-detail animation involving human characters, which is appropriate for many major crime types but has had limited use in courtrooms, could be useful for crime investigation. © 2010 American Academy of Forensic Sciences.

    The European Network of Forensic Science Institutes (ENFSI) recommended the establishment of forensic DNA databases and specific implementation and management legislations for all EU/ENFSI members. Therefore, forensic institutions from Bosnia and Herzegovina, Serbia, Montenegro, and Macedonia launched a wide set of activities to support these recommendations. To assess the current state, a regional expert team completed detailed screening and investigation of the existing forensic DNA data repositories and associated legislation in these countries. The scope also included relevant concurrent projects and a wide spectrum of different activities in relation to forensics DNA use. The state of forensic DNA analysis was also determined in the neighboring Slovenia and Croatia, which already have functional national DNA databases. There is a need for a ‘regional supplement’ to the current documentation and standards pertaining to forensic application of DNA databases, which should include regional-specific preliminary aims and recommendations.

    In this article, the authors discuss the problem of forensic authentication of digital audio recordings. Although forensic audio has been addressed in several articles, the existing approaches are focused on analog magnetic recordings, which are less prevalent because of the large amount of digital recorders available on the market (optical, solid state, hard disks, etc.). An approach based on digital signal processing that consists of spread spectrum techniques for speech watermarking is presented. This approach presents the advantage that the authentication is based on the signal itself rather than the recording format. Thus, it is valid for usual recording devices in police-controlled telephone intercepts. In addition, our proposal allows for the introduction of relevant information such as the recording date and time and all the relevant data (this is not always possible with classical systems). Our experimental results reveal that the speech watermarking procedure does not interfere in a significant way with the posterior forensic speaker identification.

  15. Conceptualising forensic science and forensic reconstruction. Part I: A conceptual model.

    Morgan, R M

    2017-11-01

    There has been a call for forensic science to actively return to the approach of scientific endeavour. The importance of incorporating an awareness of the requirements of the law in its broadest sense, and embedding research into both practice and policy within forensic science, is arguably critical to achieving such an endeavour. This paper presents a conceptual model (FoRTE) that outlines the holistic nature of trace evidence in the 'endeavour' of forensic reconstruction. This model offers insights into the different components intrinsic to transparent, reproducible and robust reconstructions in forensic science. The importance of situating evidence within the whole forensic science process (from crime scene to court), of developing evidence bases to underpin each stage, of frameworks that offer insights to the interaction of different lines of evidence, and the role of expertise in decision making are presented and their interactions identified. It is argued that such a conceptual model has value in identifying the future steps for harnessing the value of trace evidence in forensic reconstruction. It also highlights that there is a need to develop a nuanced approach to reconstructions that incorporates both empirical evidence bases and expertise. A conceptual understanding has the potential to ensure that the endeavour of forensic reconstruction has its roots in 'problem-solving' science, and can offer transparency and clarity in the conclusions and inferences drawn from trace evidence, thereby enabling the value of trace evidence to be realised in investigations and the courts.

    Nuclear forensic analysis was conducted on two uranium samples confiscated during a police investigation in Victoria, Australia. The first sample, designated NSR-F-270409-1, was a depleted uranium powder of moderate purity (∝ 1000 μg/g total elemental impurities). The chemical form of the uranium was a compound similar to K{sub 2}(UO{sub 2}){sub 3}O{sub 4} . 4H{sub 2}O. While aliquoting NSR-F-270409-1 for analysis, the body and head of a Tineid moth was discovered in the sample. The second sample, designated NSR-F-270409-2, was also a depleted uranium powder. It was of reasonably high purity (∝ 380 μg/g total elemental impurities). The chemical form of the uranium was primarily UO{sub 3} . 2H{sub 2}O, with minor phases of U{sub 3}O{sub 8} and UO{sub 2}. While aliquoting NSR-F-270409-2 for analysis, a metal staple of unknown origin was discovered in the sample. The presence of {sup 236}U and {sup 232}U in both samples indicates that the uranium feed stocks for these samples experienced a neutron flux at some point in their history. The reactor burn-up calculated from the isotopic composition of the uranium is consistent with that of spent fuel from natural uranium (NU) fueled Pu production. These nuclear forensic conclusions allow us to categorically exclude Australia as the origin of the material and greatly reduce the number of candidate sources.

Ecological. Those injured during US legal police intervention as recorded in 2012 Vital Statistics mortality census, 2012 Healthcare Cost and Utilization Project nationwide inpatient and emergency department samples, and two 2015 newspaper censuses of deaths. 2012 and 2014 arrests from Federal Bureau of Investigation data adjusted for non-reporting jurisdictions; street stops and traffic stops that involved vehicle or occupant searches, without arrest, from the 2011 Police Public Contact Survey (PPCS), with the percentage breakdown by race computed from pooled 2005, 2008 and 2011 PPCS surveys due to small case counts. US police killed or injured an estimated 55 400 people in 2012 (95% CI 47 050 to 63 740 for cases coded as police involved). Blacks, Native Americans and Hispanics had higher stop/arrest rates per 10 000 population than white non-Hispanics and Asians. On average, an estimated 1 in 291 stops/arrests resulted in hospital-treated injury or death of a suspect or bystander. Ratios of admitted and fatal injury due to legal police intervention per 10 000 stops/arrests did not differ significantly between racial/ethnic groups. Ratios rose with age, and were higher for men than women. Healthcare administrative data sets can inform public debate about injuries resulting from legal police intervention. Excess per capita death rates among blacks and youth at police hands are reflections of excess exposure. International Classification of Diseases legal intervention coding needs revision.

    A current limitation of forensic practice in Western Australia is a lack of contemporary population-specific standards for biological profiling; this directly relates to the unavailability of documented human skeletal collections. With rapidly advancing technology, however, it is now possible to acquire accurate skeletal measurements from 3D scans contained in medical databases. The purpose of the present study, therefore, is to explore the accuracy of using cranial form to predict sex in adult Australians. Both traditional and geometric morphometric methods are applied to data derived from 3D landmarks acquired in CT-reconstructed crania. The sample comprises multi-detector computed tomography scans of 200 adult individuals; following 3D volume rendering, 46 anatomical landmarks are acquired using OsiriX (version 3.9). Centroid size and shape (first 20 PCs of the Procrustes coordinates) and the inter-landmark (ILD) distances between all possible pairs of landmarks are then calculated. Sex classification effectiveness of the 3D multivariate descriptors of size and shape and selected ILD measurements are assessed and compared; robustness of findings is explored using resampling statistics. Cranial shape and size and the ILD measurements are sexually dimorphic and explain 3.2 to 54.3 % of sample variance; sex classification accuracy is 83.5-88.0 %. Sex estimation using 3D shape appears to have some advantages compared to approaches using size measurements. We have, however, identified a simple and biologically meaningful single non-traditional linear measurement (glabella-zygion) that classifies Western Australian individuals according to sex with a high degree of expected accuracy (87.5-88 %).

    Full Text Available Nanotechnology is the study of the control of matter of an atomic and molecular scale. At present the most widespread forensic application of micro fluidic systems is post-polymerase chain reaction (PCR quantization. These systems are currently being used in several forensic laboratories to perform post-PCR quantification of mitochondrial DNA. Another innovation relates to assisting in solving gun crime. Using a nanoscale developer and an X-ray source, it is possible to image the etched fingerprints even if the casing has been wiped or washed. This technology is going to revolutionize the fields of virtopsy, crime scene investigation, identification, forensic ballistics, and toxicology.

  20. Forensic anthropology in Europe: an assessment of current status and application.

    Forensic anthropology is the discipline that traditionally deals with the examination of human remains for legal purposes and it derives from the fields of anatomy, physical anthropology and forensic medicine. For more than a century, forensic anthropologists in the United States have been offering their services in the court of law complementing the medico-legal investigation of other forensic professionals. The current status in European countries is presented here. The development of forensic anthropology varies significantly among the countries of Europe. Whereas some countries show a long history of research activity in the forensic sciences, including forensic anthropology (i.e. France, Germany and Spain), others are exhibiting a recent, rapid development (i.e. United Kingdom). In some cases, forensic anthropologists are employed within the academic realm (i.e. U.K., Denmark, Portugal, Turkey), forensic institutions (Netherlands) or government organizations (Spain, Hungary), although the vast majority of them remain limited to freelance activities on a sporadic basis. Often, European scientists that deal with skeletal remains come from nonphysical anthropology disciplines such as archaeology, forensic medicine and biology. In many cases they do not have adequate training equivalent to the forensic anthropologists in the USA. Naturally, without common training and a common legal system, an accreditation system for Europe will be difficult to implement.
