The criminal profiling community can easily be split into two separate groups: those that have written criminal profiles and those that have not. It is an important distinction, because report writing is one of the most important requirements of good scientific practice. The process of writing up findings helps to reveal flaws in an examiner's logic so that they can be amended or revisited; the final report memorializes findings and their underlying basis at a fixed point in time; and as a document a forensic report provides the best mechanism for transparency and peer review. The problem is that many criminal profilers have not written criminal profiles, and still more prefer that this remain the case, often to conceal their lack of methodology. The contributors to this volume have travelled the world for more than a decade to lecture on the subjects of crime scene analysis and criminal profiling. The result has been a steady stream of requests from educational institutions and government agencies alike to teach the application of criminal profiling theory. Everyone has read the books, everyone has attended the lecture; but few have experience with hands on practice and application. In other words, there is a growing number of serious professionals who want to know how to put theory into practice and then learn what it means to put their findings into written form. Behavioral Evidence Analysis: International Forensic Practice and Protocols has been written as a companion text to Turvey's Criminal Profiling, now in its fourth edition. It is meant to provide the legion of instructors that are teaching criminal profiling as a subject with real world examples of case reports. It is also meant to serve as a desk reference for professionals that are writing crime scene analysis and criminal profiling reports, to enable sampling of structure, terminology, and references.

Using Forensic DNA Evidence at Trial: A Case Study Approach covers the most common DNA analysis methods used in criminal trials today, including STR techniques, mitochondrial DNA, and Y-STRs. It presents some novel techniques-including familial testing and analyzing domestic animal hair-that have been recently introduced in unique cases, each of which is outlined in detail. It also illustrates special issues related to forensic DNA evidence by using court proceedings such as trials and appeals, commissions of inquiry, and government and laboratory reviews. With forensic DNA analysis becoming increasingly important at trial, the lively and sometimes bizarre cases presented in this book have been carefully chosen to highlight specific concepts, methods, and interpretations used in DNA analysis. Sections throughout examine the nature of expertise with a special focus on the role of subjectivity in the interpretation of forensic DNA evidence, emphasizing cognitive bias and extraneous context. Using both convictions and exonerations as examples, the book also discusses the strengths and limitations of DNA evidence and testing. The book is written in an accessible manner for the non-scientific reader, such that criminal lawyers, judges, and forensic experts will all understand the nature of analysis and application of DNA evidence in a variety of court cases. Extensive references-including notable trial proceedings, cross references of cases, and specific forensic statistics-round out the book and help to provide a complete understanding of forensic DNA analysis and its current usage in the courtroom.

How and when did forensic science originate in the UK? This question demands our attention because our understanding of present-day forensic science is vastly enriched through gaining an appreciation of what went before. A History of Forensic Science is the first book to consider the wide spectrum of influences which went into creating the discipline in Britain in the first part of the twentieth century. This book offers a history of the development of forensic sciences, centred on the UK, but with consideration of continental and colonial influences, from around 1880 to approximately 1940. This period was central to the formation of a separate discipline of forensic science with a distinct professional identity and this book charts the strategies of the new forensic scientists to gain an authoritative voice in the courtroom and to forge a professional identity in the space between forensic medicine, scientific policing, and independent expert witnessing. In so doing, it improves our understanding of how forensic science developed as it did. This book is essential reading for academics and students engaged in the study of criminology, the history of forensic science, science and technology studies and the history of policing.

Relationship Inference in Familias and R discusses the use of Familias and R software to understand genetic kinship of two or more DNA samples. This software is commonly used for forensic cases to establish paternity, identify victims or analyze genetic evidence at crime scenes when kinship is involved. The book explores utilizing Familias software and R packages for difficult situations including inbred families, mutations and missing data from degraded DNA. The book additionally addresses identification following mass disasters, familial searching, non-autosomal marker analysis and relationship inference using linked markers. The second part of the book focuses on more statistical issues such as estimation and uncertainty of model parameters. Although written for use with human DNA, the principles can be applied to non-human genetics for animal pedigrees and/or analysis of plants for agriculture purposes. The book contains necessary tools to evaluate any type of forensic case where kinship is an issue.

This book is a scholarly work of forensic linguistics that demonstrates how the principles of Gricean pragmatics and their recent elaboration in Information Manipulation Theory (IMT) can be of use to courts faced with deciding cases of allegedly fraudulent disclosure documents. The usual goal of legal rules for disclosure documents is not merely to prevent lying but other forms of deception as well. In particular, the goal of these rules is to force the communicator to reveal information that could cause material harm to certain receivers, harms that the communicator, for various reasons of self-interest, might prefer to keep secret or hidden. Because IMT and the Gricean framework have seldom been used in published studies to investigate legally mandated disclosure documents aimed at laypersons, this book seeks to enrich current explications of the rhetorical "workings" of deceptive disclosures within the broader Gricean tradition of pragmatics. The book questions the fundamental relationships among Grice's maxims as well as the much circulated notion that violation of some maxims is more deceptive and more immoral than violations of others. In addition, the book also attempts to show how various other theories and research in discourse linguistics and reading comprehension can be used to support IMT analyses in addressing the discourse processing issues unique to legally required disclosure texts. In this way the book contributes to the larger dual mission of the field of forensic linguistics, which is both to understand and to improve courts' impact on social justice.

The ability to thoroughly and accurately photograph a crime scene is a mandate for all investigators, regardless of the time of day, weather conditions, or confines within which a piece of evidence is concealed. Evidence is commonly found in some of the most difficult to access and photograph locations. Having the knowledge, wherewithal, and skills necessary to photograph evidence in less-than-accommodating environments is vital to a photographer's effectiveness and success. Advanced Crime Scene Photography, Third Edition takes a somewhat different approach to the subject over prior editions. Rather than assuming a crime scene investigator's or photographer's comfort with the operation of their cameras-and a basic understanding of apertures, shutter speeds, ISO values, and basic exposure calculations-the author provides a thorough review of basic photographic concepts, as a refresher to readers. And, for those less familiar or otherwise new to photography, such background provided makes the foundational concepts more understandable for those readers who require such information to understand the more advanced techniques covered later in the book. In addition to this added coverage, an entirely new chapter has been added to provide essential guidance on how to prepare and testify in court. Anyone with a camera phone can take a photograph in perfect lighting, with the subject sitting out in the open, and already positioned for the best composition. This book provides crime scene photographers the skills to record those same beautiful photographs in adverse condition, surrounded by tragedy, utilizing all the tools available to the investigator. The greatest tool a photographer has available to them is their brain. From start to finish, the value of quality crime scene photographs cannot be overemphasized; photographers must take control of their photographic endeavors, identify the challenges, design a plan to capture the image correctly, and then execute that plan. As such Advanced Crime Scene Photograph, Third Edition is written to help photographers achieve the goal of capturing the best possible images, especially in those difficult-to-capture, real-world environments and conditions. All photographers need to practice their craft, whether they are actively working cases as seasoned veterans or are just beginning their careers. This book provides the knowledge and skills essential to achieve career and professional success in crime scene photography.

Forensic practitioners work in a diverse range of settings, with a wide variety of groups and with a large number of agencies. Their work, whilst rewarding, is challenging, demanding and often undertaken in highly stressful situations. Ensuring that the workforce is trained and supported is essential in order to maintain skilful, knowledgeable, responsive and effective practitioners. Whilst training, self-directed learning and peer support all play a role, the need for supervision for practitioners is increasingly being recognised. This text is aimed at all those working in forensic settings who have direct contact with the perpetrators and victims of crime and is written for both those new to supervision and those with many years' experience. Specific chapters focus on knowledge and skills for the supervisor and the supervisee and on those responsible for developing supervision systems for staff groups. This includes a focus on risk, boundaries, approaches to learning and the evidence base for supervision practice. Attention is also given to developing supervision competence and combatting harmful or 'lousy' supervision. The core text is supplemented by ten Special Topics addressing single issues commonly faced in supervision practice, such as ethical issues and reflective practice. The combination of comprehensive chapters and a focus on specific issues through ten Special Topics provides those involved in supervision with an essential resource. This book is essential reading for supervisors, students, managers and researchers who are involved or interested in the supervision process.

Traumatic Brain Injury: Methods for Clinical and Forensic Neuropsychiatric Assessment, Third Edition provides physicians and psychologists with a scientifically based schema for the clinical evaluation of traumatic brain injury (TBI). The book assists physicians and psychologists in developing treatment plans for patients who have sustained TBIs and also guides those providing forensic analysis to lawyers, insurance bodies, workers' compensation systems, triers of fact, and other stakeholders in the adjudication of victims of TBI. The procedures and recommendations in this book are grounded in highly referenced evidence-based science but also come from more than 5000 cases wherein the author and contributors have personally examined individuals who have sustained a TBI, or who claim to have sustained a TBI. This edition has been entirely rewritten. The style now follows a more traditional neuropsychiatric format than previous editions. Since the last edition, there has been increased awareness and scientific study regarding the effects of blast brain injury as a consequence of US military experiences in Afghanistan and Iraq. There is also increased interest in the phenomenology of mild traumatic brain injury and, in particular, the forensic complications associated with evaluations of this disorder. Chronic traumatic encephalopathy has also received significant scrutiny in the last decade, possibly associated with sports injuries. This book is a comprehensive resource for clinicians treating patients as well as for forensic specialists. Its purpose remains the same as in prior editions-to provide physicians or psychologists with a practical method for an effective evaluation of TBI based upon known scientific principles of brain-behavior relationships and state-of-the-art clinical, neuroimaging, neuropsychological, and psychological techniques.

Forensic Ballistics in Court: Interpretation and Presentation of Firearms Evidence is an accessible introduction to firearms and ballistics evidence and how this is analysed and presented as evidence in a court of law. The book approaches the subject in terms of the realities of case work, opening with a clear and illustrated explanation of the correct nomenclature for various weapon types and their parts. Ammunition is also extensively covered, again with annotated illustrations. Basic external and terminal ballistics, wounding capabilities are likewise covered to give an overview of the subject. A key aspect of the book covers the theory and philosophy behind striation matches and the associated statistics, how positive matches should be peer reviewed and the importance accreditation has on this subject. Gunshot residue formation and identification and the various methods used in its analysis are reviewed in depth. This includes a critical examination of the pros and cons of each type of examination and the evidential weight which can be applied to each method. * Accessible and reader-friendly introduction to firearms and ballistics. * Clarifies the limitations of firearms evidence. * Extensive use of global case-studies throughout. * Focus on the interpretation and assessment of the weight of firearms/ballistics evidence presented at court. * Covers the importance of witness and accused statements and their interpretation in relation to the investigation under review. * Includes coverage of gunshot residue collection, examination and interpretation and the potential for contamination of GSR samples. * Includes numerous real life case studies that the author has dealt with over the past 45 years. * Takes an applied approach to the subject.

Miscarriages of justice are a regular occurrence in the criminal justice system, which is characterized by government agencies that are understaffed, underfunded, and undertrained across the board. We know this because, every week, DNA testing and innocence projects across the United States help to identify and eventually overturn wrongful convictions. As a result, the exonerated go free and the stage is set for addressing criminal and civil liability. Criminal justice students and professionals therefore have a need to be made aware of the miscarriage problem as a threshold issue. They need to know what a miscarriage of justice looks like, how to recognize it's many forms, and what their duty of care might be in terms of prevention. They also need to appreciate that identifying miscarriages, and ensuring legal remedy, is an important function of the system that must be honored by all criminal justice professionals. The purpose of this textbook is to move beyond the law review, casebook, and true crime publications that comprise the majority of miscarriage literature. While informative, they are not designed for teaching students in a classroom setting. This text is written for use at the undergraduate level in journalism, sociology, criminology and criminal justice programs - to introduce college students to the miscarriage phenomenon in a structured fashion. The language is more broadly accessible than can be found in legal texts, and the coverage is multidisciplinary. Miscarriages of Justice: Actual Innocence, Forensic Evidence, and the Law focuses on the variety of miscarriages issues in the United States legal system. Written by leaders in the field, it is particularly valuable to forensic scientists and attorneys evaluating evidence or preparing for trial or appeal in cases where faulty evidence features prominently. It is also of value to those interested in developing arguments for miscarriage in post-conviction review of criminal cases. Chapters focus specifically on issues of law enforcement bias and corruption; false confessions; ineffective counsel and prosecutorial misconduct; forensic fraud; and more. The book closes by examining innocence projects and commissions, and civil remedies for the wrongfully convicted. This text ultimately presents the issue of miscarriages as a systemic and multi-disciplinary criminal justice issue. It provides perspectives from within the professional CJ community, and it serves as warning to future professionals about the dangers and consequences of apathy, incompetence, and neglect. Consequently, it can be used by any CJ educator to introduce any group of CJ students to the problem.

Over the past several years, myriad manuals on crime scene investigations have been published with each focusing on select, or partial, aspects of the investigation. Crime scene investigation, done right, is a multi-faceted process that requires various forms of evidence to be collected, examined, and analyzed. No book available has addressed procedures to present global best practices by assembling a collection of international experts to address such topics. Manual of Crime Scene Investigation is a comprehensive collaboration of experts writing on their particular areas of expertise as relates to crime scenes, evidence, and crime scene investigation. The book outlines best practices in the field, incorporating the latest technology to collect, preserve, and enhance evidence for appropriate analysis. Various types of forensic evidence are addressed, covering chain of custody, collection, and utility of such evidence in casework, investigations, and for use in court. The approach, and use of international contributor experts, will appeal to a broad audience and be of use to forensic practitioners, and the forensic science community worldwide. Key features: * Assembles an international team of contributing author experts to present the latest developments in their crime scene field of specialty * Examines global best practices and what are consistently the most reliable tactics and approach to crime scene evidence collection, preservation, and investigation * Provides numerous photographs and diagrams to clearly illustrate chapter concepts Manual of Crime Scene Investigation serves as a vital resource to professionals in police science and crime scene investigations, private forensic institutions, and academics researching how better real-world application of techniques can improve the reliability and utility of evidence upon forensic and laboratory analysis.

Evidence Found: An Approach to Crime Scene Investigation is not another analysis of forensic errors using an "After the Fact" or "Lessons Learned" approach but a "Before the Fact" guide that examines the thought processes that can lead to those mistakes. Plus a few extras tips and tricks from the author's experience of over 25 years. Many high-profile crime scene investigations (and routine ones, for that matter) have suffered errors that have had negative impact on the investigation result and in the courtroom. Typically, we examine what happened and develop a useful list of what to do and what not to do, fixing the symptoms but potentially leaving ourselves open to the same error type on the next scene. The reason? Many crime scene mistakes are the result of systemic issues that are repeated due to a failure to include an evaluation of the decision-making process, including our own foundations of knowledge. Through case study and logical argument, this book attempts to provide a framework to recognize, evaluate, and alter negative decision-making patterns, including evaluating our own experience, before they negatively impact an investigation or the overall operation of a forensic unit.

Forensic work occurs across the criminal justice sector and the legal and health professions and intersects with work in a range of areas, such as child protection, family welfare, mental health, offending, disability and addictions, family violence programmes, juvenile justice and sexual assault centres. This book offers contemporary perspectives on forensic policy and practice from the range of practitioners working with people within the forensic domain and canvasses ideas about risk and offending behaviours together with ideas about effective responses to rehabilitation and recovery.

The contributors to this proposed book are drawn from the practitioners, policy contributors, advocates and researchers in mental health, welfare, law, criminology, policing and health. Negligible attention has been paid to forensic policy and practice; this proposed book offers cross-national attention to how mental health, welfare and justice systems intersect, who they affect, and how practitioners structure effective responses for vulnerable people within the forensic domain.

A particular strength of the book is its international focus, making it relevant to academics and practitioners who work in this field around the world.

The investigator's practical guide for cybercrime evidence identification and collection Cyber attacks perpetrated against businesses, governments, organizations, and individuals have been occurring for decades. Many attacks are discovered only after the data has been exploited or sold on the criminal markets. Cyber attacks damage both the finances and reputations of businesses and cause damage to the ultimate victims of the crime. From the perspective of the criminal, the current state of inconsistent security policies and lax investigative procedures is a profitable and low-risk opportunity for cyber attacks. They can cause immense harm to individuals or businesses online and make large sums of money--safe in the knowledge that the victim will rarely report the matter to the police. For those tasked with probing such crimes in the field, information on investigative methodology is scarce. The Cybercrime Investigators Handbook is an innovative guide that approaches cybercrime investigation from the field-practitioner's perspective. While there are high-quality manuals for conducting digital examinations on a device or network that has been hacked, the Cybercrime Investigators Handbook is the first guide on how to commence an investigation from the location the offence occurred--the scene of the cybercrime--and collect the evidence necessary to locate and prosecute the offender. This valuable contribution to the field teaches readers to locate, lawfully seize, preserve, examine, interpret, and manage the technical evidence that is vital for effective cybercrime investigation. Fills the need for a field manual for front-line cybercrime investigators Provides practical guidance with clear, easy-to-understand language Approaches cybercrime form the perspective of the field practitioner Helps companies comply with new GDPR guidelines Offers expert advice from a law enforcement professional who specializes in cybercrime investigation and IT security Cybercrime Investigators Handbook is much-needed resource for law enforcement and cybercrime investigators, CFOs, IT auditors, fraud investigators, and other practitioners in related areas.

Ancestry determination in the identification of unknown remains can be a challenge for forensic scientists and anthropologists, especially when the remains available for testing are limited. There are various techniques for the assessment of ancestry, ranging from traditional to new microbiological and computer-assisted methods. Biological Affinity in Forensic Identification of Human Skeletal Remains: Beyond Black and White presents a range of tools that can be used to identify the probable socio-cultural "race" category of unknown human remains. Gathering insight from those who have made recent improvements and scientific advances in the field, the book begins with the historical foundations of the concept of biological affinity and the need for increased research into methods for determining ancestry of skeletal remains. The contributors cover a range of topics, including: Ancestry estimation from the skull using morphoscopic and morphometric traits and variables Innovative methods from metric analyses of the postcrania, and new approaches to dental non-metric variation The biological diversity of Hispanic populations and use of discriminant function analysis and 3D-ID software to determine ancestry Methods of age progression and facial reconstructions to create two-dimensional (2D) and three-dimensional (3D) facial composites for missing people The preparation of skeletal remains for DNA extraction and sampling, and mtDNA methods that are available for identification of haplogroups (e.g., ancestral populations) No single method or technique is adequate in the assessment of ancestry. For accurate determinations, the use of traditional and new techniques combined yields better results. This book demonstrates the large repertoire of tools available to those tasked with these challenging determinations.

In 2001, the late Murray Kleiner and an array of experts contributed to the "Handbook of Polygraph Testing," published by Elsevier, which examined the fundamental principles behind polygraph tests and reviewed the key tests and methods used at that time. In the intervening thirteen years, the field has moved beyond traditional polygraph testing to include a host of biometrics and behavioral observations. The new title reflects the breadth of methods now used. "

Credibility Assessment "builds on the content provided in the Kleiner volume, with revised polygraph testing chapters and chapters on newer methodologies, such as CNS, Ocular-motor, and behavioral measures. Deception detection is a major field of interest in criminal investigation and prosecution, national security screening, and screening at ports of entry. Many of these methods have a long history, e.g., polygraph examinations, and some rely on relatively new technologies, e.g., fMRI and Ocular-motor measurements. Others rely on behavioral observations of persons in less restricted settings, e.g., airport screening. The authors, all of whom are internationally-recognized experts associated with major universities in the United States, United Kingdom, and Europe, review and analyze various methods for the detection of deception, their current applications, and major issues and controversies surrounding their uses. This volume will be of great interest among forensic psychologists, psychophysiologists, polygraph examiners, law enforcement, courts, attorneys, and government agencies.
Provides a comprehensive review of all aspects of methods for deception detectionIncludes methods being used in credibility, such as autonomic, CNS, fMRI, and Ocular-motor measures and behavioral and facial observationEdited by leaders in the field with over 25+ years of experienceDiscusses theory and application

In recent years, the use of illegally produced firearms has increased exponentially worldwide. These are often cheap, nonstandard firearms that defy known classification and identification criteria. The use of unusual firearms in crimes has frequently led to unpredictable and misleading reconstruction of shooting incidents. In this book, internationally known forensic firearm expert, J.K. Sinha, presents a detailed forensic study of unusual firearms, with the goal of helping crime-scene investigators to minimize erroneous conclusions in cases where these types of firearms are used. Based on his extensive experimentation with more than 1,000 nonstandard firearms, the author identifies new class characteristic parameters needed to establish linkage of projectiles with irregular rifled and smoothbore barrels. The book begins with an introduction to unusual firearms and proceeds to discuss forensic investigation of fired bullets, medico-legal evidence, barrel marks on fired shots, and investigation of fired cartridges and shot charge. Chapters also cover topics such as timing of firing, unusual rifling marks, shooter identification, and unusual bullet hole evaluations. Providing concise yet complete techniques for making forensic analyses and conclusions, this is the first book of its kind to critically examine the use of unusual, nonstandard firearms in perpetrating crimes. It is intended for professionals and academicians working in the field: forensic firearm experts and consultants, forensic medicine professionals and medico-legal experts, prosecution and defense attorneys, enforcement agencies and judiciary, university students and researchers studying forensic science, forensic medicine, criminology and law.
