DNA testing and its forensic analysis are recognized as the "gold standard" in forensic identification science methods. However, there is a great need for a hands-on step-by-step guide to teach the forensic DNA community how to interpret DNA mixtures, how to assign a likelihood ratio, and how to use the subsequent likelihood ratio when reporting interpretation conclusions. Forensic DNA Profiling: A Practical Guide to Assigning Likelihood Ratios will provide a roadmap for labs all over the world and the next generation of analysts who need this foundational understanding. The techniques used in forensic DNA analysis are based upon the accepted principles of molecular biology. The interpretation of a good-quality DNA profile generated from a crime scene stain from a single-source donor provides an unambiguous result when using the most modern forensic DNA methods. Unfortunately, many crime scene profiles are not single source. They are described as mixed since they contain DNA from two or more individuals. Interpretation of DNA mixtures represents one of the greatest challenges to the forensic DNA analyst. As such, the book introduces terms used to describe DNA profiles and profile interpretation. Chapters explain DNA extraction methods, the polymerase chain reaction (PCR), capillary electrophoresis (CE), likelihood ratios (LRs) and their interpretation, and population genetic models-including Mendelian inheritance and Hardy-Weinberg equilibrium. It is important that analysts understand how LRs are generated in a probabilistic framework, ideally with an appreciation of both semicontinuous and fully continuous probabilistic approaches. KEY FEATURES: * The first book to focus entirely on DNA mixtures and the complexities involved with interpreting the results * Takes a hands-on approach offering theory with worked examples and exercises to be easily understood and implementable by laboratory personnel * New methods, heretofore unpublished previously, provide a means to innovate deconvoluting a mixed DNA profile, assign an LR, and appropriately report the weight of evidence * Includes a chapter on assigning LRs for close relatives (i.e., "It's not me, it was my brother"), and discusses strategies for the validation of probabilistic genotyping software Forensic DNA Profiling fills the void for labs unfamiliar with LRs, and moving to probabilistic solutions, and for labs already familiar with LRs, but wishing to understand how they are calculated in more detail. The book will be a welcome read for lab professionals and technicians, students, and legal professionals seeking to understand and apply the techniques covered.

Despite a shared focus on crime and its 'extended family', forensic scientists and criminologists tend to work in isolation rather than sharing the data, methods and knowledge that will broaden the understanding of the criminal phenomenon and its related subjects. Bringing together perspectives from international experts, this book explores the intersection between criminology and forensic science and considers how knowledge from both fields can contribute to a better understanding of crime and offer new directions in theory and methodology. This handbook is divided into three parts: Part I explores the epistemological and historical components of criminology and forensic science, focusing on their scientific and social origins. Part II considers how collaboration between these disciplines can bring about a better understanding of the organizations and institutions that react to crime, including the court, intelligence, prevention, crime scene investigation and policing. Part III discusses the phenomena and actors that produce crime, including a reflection on the methodological issues, challenges and rewards regarding the sharing of these two disciplines. The objective of this handbook is to stimulate a 'new' interdisciplinary take on the study of crime, to show how both forensic and criminological theories and knowledge can be combined to analyse crime problems and to open new methodological perspectives. It will be essential reading for students and researchers engaged with forensic science, criminology, criminal behaviour, criminal investigation, crime analysis and criminal justice.

While it is not possible to predict - or necessarily prevent - terrorist incidents in which chemical warfare agents (CWAs) and toxic industrial chemicals (TICs) are deployed, correctly chosen, fast, and reliable detection equipment will allow prepared rescue workers to respond quickly and minimize potential casualties. Detection Technologies for Chemical Warfare Agents and Toxic Vapors discusses the principles, instrumentation, and context for applying technologies such as ion mobility spectrometry, infrared spectroscopy, colorimetric chemistry, and flame ionization to the detection of TICs and lethal CWAs. It conveys techniques - some of which have been patented by the authors - developed for generating vapors and closely imitating potential environmental effects in a laboratory setting, specifically for the testing and evaluation of hand-held, portable, and remote devices. This book also provides a comprehensive list of toxic industrial chemicals classified in terms of hazardousness and their physical, chemical, and toxicological properties. Following a brief historical overview, the text also includes a review of federal detection requirements and the government's rationale for preparedness and response. By providing insight on the behavior of toxic chemicals, the authors hope to minimize the fear and chaotic effect in a potential event involving chemical agents. Well written and accessible to technical and non-technical audiences, no other book focuses on analytical methods and explains current detection devices for chemical warfare agents.

Would you kill for love? True-crime master Ron Franscell tells the grisly story of Alice and Gerald Uden, a loving couple who murdered at least four people, and live happily ever after--while cops try for decades to piece together a petrifying tale of murder and secrets. The appalling details are made even more vivid by the author's familiarity with the Wyoming times and places that formed the backdrop of his national bestseller The Darkest Night. In 1974, Alice, a desperate young mother in a gritty Wyoming boomtown, kills her husband and dumps his body where it will never be found, then slips away and starts a new life. But when her new man's ex-wife and two kids start demanding more of him, Alice delivers an ultimatum: Fix the problem or lose her forever. With Alice's help, Gerald "fixes" the problem in an extraordinarily ghastly way . . . and they live happily ever after. That is, until 2013, almost forty years later, when somebody finds a dead man's skeleton in a place where Alice thought he'd never be found. This page-turner by bestselling true-crime author Ron Franscell revisits a shocking cold case that was finally solved just when the murderers thought they'd never be caught.

Digital Forensic Art Techniques: A Professional's Guide to Corel PainterTM illustrates hands-on techniques to digitally create forensic art for police and investigative purposes. Coverage focuses specifically on how to utilize the software to create realistic human likenesses, including composites of suspects and drawings of persons in unidentified remains cases. Drawing digitally is like using any tool in art: a pencil, a charcoal stick, a conte' crayon. A stylus is just another tool to master. Digital work is easier for artists to send to the case detective, and the work always reproduces exactly as it was completed. Another benefit to working digitally is that one can use video conferencing with a witness online to provide services remotely world-wide. This enables police departments who have never had access to a forensic artist to have a sketch done within hours of the crime. Chapters address the more basic functions to serve as a primer for those transitioning to working digitally. There is also instruction on light and shadow, and bones and muscles of the skull. All of the discussion is intended to make the reader see things as an artist to improve drawing skills and overall digital techniques. In short, Digital Forensic Art Techniques is a practical, easy-to-follow manual for working forensic artists that will give readers a solid base from which to start. It serves as an essential resource to greater skill and comfort with the hardware and software, thus furthering current best practices and technological advances in the field.

This book addresses the use of biometrics - including fingerprint identification, DNA identification and facial recognition - in the criminal justice system: balancing the need to ensure society is protected from harms, such as crime and terrorism, while also preserving individual rights. It offers a comprehensive discussion of biometric identification that includes a consideration of: basic scientific principles, their historical development, the perspectives of political philosophy, critical security and surveillance studies; but especially the relevant law, policy and regulatory issues. Developments in key jurisdictions where the technology has been implemented, including the United Kingdom, United States, Europe and Australia, are examined. This includes case studies relating to the implementation of new technology, policy, legislation, court judgements, and where available, empirical evaluations of the use of biometrics in criminal justice systems. Examples from non-western areas of the world are also considered. Accessibly written, this book will be of interest to undergraduate, postgraduate and research students, academic researchers, as well as professionals in government, security, legal and private sectors.

The Psychology of Death Investigations outlines definitively how behavioral evidence can often provide the necessary components and "missing pieces" to complement physical evidence as an essential tool for incident reconstruction. In order to determine the direction of an investigation and to prioritize leads, if necessary, death investigators must establish the manner of a death: natural, accident, homicide or suicide. The most overlooked aspect of death investigation is the psychological dimension, which can provide unique leads, correct false assumptions, enhance investigative awareness, and solve cases in surprising ways. In an estimated 10-20% of cases, the manner of death cannot be determined, or worse, has been erroneously categorized. Since many jurisdictions can't afford behavioral consultants, this book has been written to provide practical information for a basic psychological analysis. If the circumstances surrounding a death are equivocal, psychological consultants can compile information retrospectively about a deceased person's mental state and possible motive to assist with unravelling ambiguity about the manner of death. This is the primary function of a psychological autopsy, and, as such, this is the first book of its kind dedicated solely to the topic. In the event that the manner of death is determined to be a homicide, behavioral profiling can help to focus the potential pool of suspects. Professionals and students alike will benefit from the exercise of cognitive awareness and the application of psychological logic presented. Psychologists, medical examiners, coroners, attorneys, fraud examiners, law enforcement personnel, death and homicide investigators, and students enrolled in criminal profiling, forensic psychology, and criminal justice programs will find this text to be a compelling and insightful reference to add to their professional toolkit.

When a corpse is found in a body of water, authorities generally presume that the manner of death was either an accident or a suicide. They do not treat the recovery site as a potential crime scene or homicide, so many cases remain unsolved. Case Studies in Drowning Forensics investigates the cases of 13 bodies recovered from water in similar circumstances and one survivor. The product of intensive field investigation and archival research, this is the first book that presents and explains forensic autopsy evidence associated with the "Smiley Face" murders. Each chapter begins with background information on the victim in the case and discusses when and where the victim was last seen and how the body was recovered. This is followed by in-depth analysis of the evidence found and the peculiarities of each case. Gannon and Gilbertson challenge authorities' determinations regarding cause and manner of death by critically examining autopsy, toxicology, and law enforcement reports and photographs. They also reveal evidence not previously made public-including search efforts, cell phone records, GPS data, and additional drug tests. Building on each successive case study, they explain relationships among postmortem artifacts in a graphic format. Presenting the inside truth on the circumstances and the evidence, the book enables readers to determine for themselves whether the deaths of these young men were accidents or homicides.

Advances in Paleoimaging: Applications for Paleoanthropology, Bioarchaeology, Forensics, and Cultural Artifacts builds on the research and advances in technology since the writing of the authors' first book, Paleoimaging: Field Applications for Cultural Remains and Artifacts (ISBN: 978-1-4200-9071-0). Since Paleoimaging was published in 2009, additional research settings for the application of advanced imaging technologies have been identified. Practices are now more widespread and standardized with the capabilities and utilization of imaging methodologies increasing dramatically. Given the numerous advances in paleoimaging technique and technology, this book chronicles the evolution that has taken place in all the imaging modalities. Chapters include the coverage of magnetic resonance imaging, computed tomography, plane and digital radiography, endoscopy, and applications of x-ray fluorescence, as well as the principles of industrial radiography. While the book focuses on a multimodal imaging approach to anthropological and archaeological research, the authors and contributing authors have vast experience in other areas and present coverage of biological applications as well. The multidisciplinary chapters provide a foundation to understand the application of various imaging modalities in archaeological, anthropological, bioanthropological, and forensic settings. As such, Advances in Paleoimaging will serve as an essential reference for conservators, museum archivists, forensic anthropologists, paleopathologists, and archaeologists, who perform non-destructive research on historical or culturally significant artifacts, remains, or material from a forensic investigation. The concepts and methods presented in this text are supported with case presentations of the authors' vast experience in the new companion book, Case Studies for Advances in Paleoimaging (ISBN: 978-0-367-25166-6) by Beckett, Conlogue, and Nelson (2020).

The emergence of the World Wide Web, smartphones, and computers has transformed the world and enabled individuals to engage in crimes in a multitude of new ways. Criminological scholarship on these issues has increased dramatically over the last decade, as have studies on ways to prevent and police these offenses. This book is one of the first texts to provide a comprehensive review of research regarding cybercrime, policing and enforcing these offenses, and the prevention of various offenses as global change and technology adoption increases the risk of victimization around the world. Drawing on a wide range of literature, Holt and Bossler offer an extensive synthesis of numerous contemporary topics such as theories used to account for cybercrime, policing in domestic and transnational contexts, cybercrime victimization and issues in cybercrime prevention. The findings provide a roadmap for future research in cybercrime, policing, and technology, and discuss key controversies in the existing research literature in a way that is otherwise absent from textbooks and general cybercrime readers. This book is an invaluable resource for academics, practitioners, and students interested in understanding the state of the art in social science research. It will be of particular interest to scholars and students interested in cybercrime, cyber-deviance, victimization, policing, criminological theory, and technology in general.

This book examines the legal and policy aspects of cyber-security. It takes a much needed look at cyber-security from a geopolitical perspective. Through this lens, it seeks to broaden the reader's understanding of the legal and political considerations of individuals, corporations, law enforcement and regulatory bodies and management of the complex relationships between them. In drawing on interviews conducted with experts from a wide range of fields, the book presents the reader with dilemmas and paradigms that confront law makers, corporate leaders, law enforcement, and national leaders. The book is structured in a novel format by employing a series of vignettes which have been created as exercises intended to confront the reader with the dilemmas involved in cyber-security. Through the use of vignettes, the work seeks to highlight the constant threat of cyber-security against various audiences, with the overall aim of facilitating discussion and reaction to actual probable events. In this sense, the book seeks to provide recommendations for best practices in response to the complex and numerous threats related to cyber-security. This book will be of interest to students of cyber-security, terrorism, international law, security studies and IR in general, as well as policy makers, professionals and law-enforcement officials.

Barry Fisher s Techniques of Crime Scene Investigation has long been considered the "bible" of the crime-solving profession, drawing from the author s 40-year career in forensic science, including his time spent as the crime laboratory director for the Los Angeles County Sheriff s Department. Now for the first time, commissioned authors working out of the United Kingdom and Denmark present Fisher s Techniques of Crime Scene Investigation First International Edition the latest edition of a classic volume, now oriented specifically to an international audience.

Maintaining the same format as the U.S. editions, the book focuses on international procedures, laws, and cases. The book s three-part structure highlights the importance of approaching the topic from three consecutive perspectives. The first is that crime scene investigation is a subdiscipline of forensic science, and thus the first section, entirely new to this edition, explores the forensic process and the basic principles and practices of crime scene investigation.

The second perspective is that crime scene investigation is about identifying and recovering different forms of evidence, each with its own methods for identification, recovery, and analysis. To that end, the book discusses trace and impression evidence, establishing personal identity, forensic biology, and evidence associated with firearms, arson, and explosions.

Lastly, crime scene investigation is ultimately about describing the location, modus operandi, time frame and sequence of events, identity of persons involved, and motive for different types of crime. Highlighting this focus, the final section presents chapters on the investigation of various crime scenarios, including those involving illicit drugs, sexual assault, burglary, motor vehicles, and homicide. The book closes with new appendices exploring the cutting-edge world of digital evidence.

Enhanced with hundreds of diagrams and color photos of actual crime scenes, this volume combines time-tested procedures with an international scope to provide an essential resource for investigators in Europe, Australasia, and Canada charged with solving crimes and bringing offenders to justice. William Tilstone talks about the book on the CRC Press YouTube Channel.

This is a book about Edwin H. Sutherland's theory of differ ential association. I received my Ph. D. from Indiana University, where I worked with Sutherland, and the volume is made up principally of my writings on differential association during the years 1952-1963. However, the volume is neither a festschrift nor a book of reprints. The original materials have in most cases been quite severely edited in order to give the volume coherence and in order to minimize repetition and redundancy. For example, portions of one journal article appear in Chapters I, IV and V; parts of a chapter published in a recent book appear in Chapters I, II and III; and Chapter IX is composed of two inter-related articles, published eight years apart. Chapter I has not appeared elsewhere in its present form, but most of it consists of snippets culled from several of my articles and books and woven together in new form. The book is intended primarily for non-American readers, who on the whole are not as familiar with Sutherland's theory (or with other sociological and social psychological theories about delinquency, crime and corrections) as are Americans. Yet at least a nodding acquaintance with Sutherland's work is becoming increasingly necessary to an intelligent reading of the American literature in criminology."

Since its publication, the first edition of Fingerprints and Other Ridge Skin Impressions has become a classic in the field. This second edition is completely updated, focusing on the latest technology and techniques-including current detection procedures, applicable processing and analysis methods-all while incorporating the expansive growth of literature on the topic since the publication of the original edition. Forensic science has been challenged in recent years as a result of errors, courts and other scientists contesting verdicts, and changes of a fundamental nature related to previous claims of infallibility and absolute individualization. As such, these factors represent a fundamental change in the way training, identifying, and reporting should be conducted. This book addresses these questions with a clear viewpoint as to where the profession-and ridge skin identification in particular-must go and what efforts and research will help develop the field over the next several years. The second edition introduces several new topics, including Discussion of ACE-V and research results from ACE-V studies Computerized marking systems to help examiners produce reports New probabilistic models and decision theories about ridge skin evidence interpretation, introducing Bayesnet tools Fundamental understanding of ridge mark detection techniques, with the introduction of new aspects such as nanotechnology, immunology and hyperspectral imaging Overview of reagent preparation and application Chapters cover all aspects of the subject, including the formation of friction ridges on the skin, the deposition of latent marks, ridge skin mark identification, the detection and enhancement of such marks, as well the recording of fingerprint evidence. The book serves as an essential reference for practitioners working in the field of fingermark detection and identification, as well as legal and police professionals and anyone studying forensic science with a view to understanding current thoughts and challenges in dactyloscopy.

Molecules of Murder is about infamous murderers and famous victims; about people like Harold Shipman, Alexander Litvinenko, Adelaide Bartlett, and Georgi Markov. Few books on poisons analyse these crimes from the viewpoint of the poison itself, doing so throws a new light on how the murders or attempted murders were carried out and ultimately how the perpetrators were uncovered and brought to justice. Part I includes molecules which occur naturally and were originally used by doctors before becoming notorious as murder weapons. Part II deals with unnatural molecules, mainly man-made, and they too have been dangerously misused in famous crimes. The book ends with the most famous poisoning case in recent years, that of Alexander Litvinenko and his death from polonium chloride. The first half of each chapter starts by looking at the target molecule itself, its discovery, its history, its chemistry, its use in medicine, its toxicology, and its effects on the human body. The second half then investigates a famous murder case and reveals the modus operandi of the poisoner and how some were caught, some are still at large, and some literally got away with murder. Molecules of Murder will explain how forensic chemists have developed cunning ways to detect minute traces of dangerous substances, and explain why some of these poisons, which appear so life-threatening, are now being researched as possible life-savers. Award winning science writer John Emsley has assembled another group of true crime and chemistry stories to rival those of his highly acclaimed Elements of Murder.
