National DNA databanks were initially established to catalogue the identities of violent criminals and sex offenders. However, since the mid-1990s, forensic DNA databanks have in some cases expanded to include people merely arrested, regardless of whether they've been charged or convicted of a crime. The public is largely unaware of these changes and the advances that biotechnology and forensic DNA science have made possible. Yet many citizens are beginning to realize that the unfettered collection of DNA profiles might compromise our basic freedoms and rights.

Two leading authors on medical ethics, science policy, and civil liberties take a hard look at how the United States has balanced the use of DNA technology, particularly the use of DNA databanks in criminal justice, with the privacy rights of its citizenry. Krimsky and Simoncelli analyze the constitutional, ethical, and sociopolitical implications of expanded DNA collection in the United States and compare these findings to trends in the United Kingdom, Japan, Australia, Germany, and Italy. They explore many controversial topics, including the legal precedent for taking DNA from juveniles, the search for possible family members of suspects in DNA databases, the launch of "DNA dragnets" among local populations, and the warrantless acquisition by police of so-called abandoned DNA in the search for suspects. Most intriguing, Krimsky and Simoncelli explode the myth that DNA profiling is infallible, which has profound implications for criminal justice.

In the wake of the Daubert ruling, the use of forensic toolmark evidence in court has been problematic, in that the conclusions of forensic scientists as to toolmark origin often lack scientifically sound statistical proof. In the Color Atlas of Forensic Toolmark Identification, noted forensic expert Nicholas Petraco helps move toolmark examination from an art to a science. The first part of the book contains an anthology of tried and true methods, procedures, and traditional techniques used by practitioners of this discipline for over a century. It contains rationales and methodologies for casework, discussion of the use of new materials and techniques for preparation of known standards, and the application of various methods of statistical proof to further establish toolmark examination as a sound scientific endeavor. The second section contains a compilation of commonly used hand tools and the marks they typically produce. Provides clear instruction on how to: Use lenses and microscopes to view images of toolmarks Make accurate and precise measurements of tools on macroscopic and microscopic scales Properly photograph toolmark evidence Compare a subject tool with the questioned toolmarks to determine toolmark origin Examines marks made by a range of tools, including: Screwdrivers Crowbars and prybars Handsaws Hammers Hatchets and Axes Wrenches Vise grips Pliers Wire cutters Metal snips Crimping tools Knives and scissors Chisels and punches Drill bits More than 400 color photos enhance the text, and numerous case studies describe evidence found and conclusions drawn from the evidence. This unique atlas empowers law enforcement professionals to capture the evidence they need to solve the case. About the Author Nicholas Petraco earned a B.S. in chemistry and an M.S. in forensic science from John Jay College of Criminal Justice, the City University of New York. He served as a detective/criminalist at New York City's Police Laboratory from 1968 to 1990 and held the position of senior forensic microscopist of the laboratory's trace section between 1982 and 1990, when he became a private forensic consultant. Mr. Petraco has helped educate thousands of forensic scientists, worked on more than 5000 death investigations on behalf of prosecution and defense attorneys, and testified as an expert in more than 500 trials conducted in local, state, and federal criminal and civil courts.

This volume serves to provide an international overview of personal injury compensation in different geographical areas (15 countries already included), with a special focus on the methods used to ascertain the injury and the related damages. It also goes on to clarify the logical and methodological steps required for a sequential, in-depth ascertainment of any traumatic event and the related personal damage, both pecuniary and non-pecuniary. Personal injury is a legal term for an injury to the body, mind or emotions suffered by the plaintiff under tort and/or civil law regulations. Damages related to the injury can be pecuniary or non-pecuniary in nature. Although several comparative studies and research projects on tort and civil law and personal injury claims aimed at developing new tools for promoting harmonization of private law have been performed at an international level, heterogeneity and divergences still exist in the definition and compensation of personal injury and damage across different national legislative systems. The starting point for any awarding procedure should be a medical, or rather a medico-legal, assessment to gain evidence on the trauma or event causing the injury, the mechanism of injury, the pre-existing health status of the injured party, and the health consequences of the injury (temporary and permanent impairment, work incapacity, etc.). In order to pursue the ultimate goal of an international harmonization of personal injury compensation, it is of upmost importance to define the quality requirements for the medico-legal ascertainment methodology, which are essential for guaranteeing the objectivity, rigor, and reproducibility of the data and the evidence collection procedure. Currently, there are no supra-national medico-legal guidelines dealing with the ascertainment methodology of personal injury and damage under tort and civil law.

The interpretation and evaluation of scientific evidence and its presentation in a court of law is central both to the role of the forensic scientist as an expert witness and to the interests of justice. This book aims to provide a thorough and detailed discussion of the principles and practice of evidence interpretation and evaluation by using real cases by way of illustration. The presentation is appropriate for students of forensic science or related disciplines at advanced undergraduate and master's level or for practitioners engaged in continuing professional development activity. The book is structured in three sections. The first sets the scene by describing and debating the issues around the admissibility and reliability of scientific evidence presented to the court. In the second section, the principles underpinning interpretation and evaluation are explained, including discussion of those formal statistical methods founded on Bayesian inference. The following chapters present perspectives on the evaluation and presentation of evidence in the context of a single type or class of scientific evidence, from DNA to the analysis of documents. For each, the science underpinning the analysis and interpretation of the forensic materials is explained, followed by the presentation of cases which illustrate the variety of approaches that have been taken in providing expert scientific opinion.

This introductory volume to a new series on Soil Forensics gives a kaleidoscopic view of a developing forensic expertise. Forensic practitioners and academic researchers demonstrate, by their joint contributions, the extent and complexity of soil forensics. their reports exemplify the broad range of sciences and techniques applied in all stages of forensic soil examinations, from investigations at crime scenes to providing evidence that can be used in court proceedings. Moreover the necessity is depicted of co-operation as a condition for any work in soil forensics between scientists of different disciplines, but no less between scientists and law enforcers.Soils play a role in environmental crimes and liability, as trace evidence in criminal investigations and, when searching for and evaluating, buried human remains. This book shows soil forensics as practiced in this legal context, emerging and solidifying in many countries all over the world, differing in some respects because of differences in legal systems but ultimately sharing common grounds.

As scholars have by now long contended, global neoliberalism and the violence associated with state restructuring provide key frameworks for understanding flows of people across national boundaries and, eventually, into the treacherous terrains of the United States borderlands. The proposed volume builds on this tradition of situating migration and migrant death within broad, systems-level frameworks of analysis, but contends that there is another, perhaps somewhat less tidy, but no less important sociopolitical story to be told here. Through examination of how forensic scientists define, navigate, and enact their work at the frontiers of US policy and economics, this book joins a robust body of literature dedicated to bridging social theory with bioarchaeological applications to modern day problems. This volume is based on deeply and critically reflective analyses, submitted by individual scholars, wherein they navigate and position themselves as social actors embedded within and, perhaps partially constituted by, relations of power, cultural ideologies, and the social structures characterizing this moment in history. Each contribution addresses a different variation on themes of power relations, production of knowledge, and reflexivity in practice. In sum, however, the chapters of this book trace relationships between institutions, entities, and individuals comprising the landscapes of migrant death and repatriation and considers their articulation with sociopolitical dynamics of the neoliberal state.

Aimed at the busy professional who aspires to become certified in the field, Criminal Investigation for the Professional Investigator is a single source guide that details essential techniques a trained investigator will be called upon to perform during the course of a career. Comprehensive and accessible, the book is authored by a veteran of the NYPD who gained extensive training and experience and went on to launch and operate two successful private investigation agencies.

After 17 years of private practice as a cardiovascular surgeon, my partners qu- tionedtherationalityofmydecisiontoleavetheclinicalpracticebehindandbecome acardiovascular pathologist. Infact,theirdisbeliefofmyintentiontomakethe"leap of faith" was understandable. For a surgeon, the operating room is where the action is. It is as simple as that. And when a cardiac surgeon can hold in his hand a beating heart, now off-bypass and improved by an operation just completed, satisfaction is real and profound. However, life is complex. Throughout my surgical career, questions regarding the pathogenesis of atherosclerotic cardiovascular disease arose; curiosities of va- ous phenotypes of the disease piqued my interest. I became aware of the power of investigative techniques that might address these questions. I then began to realize that my career in the operating room left me little time to address them. I needed to study the disease full time in order to contribute to my understanding of it. Ironically, my ?rst autopsy as a pathology resident was on an individual with a past history of coronary artery bypass surgery. When it came to examining the heart, the dissection, as all pathologists know, was complex. However, I found it to be straightforward and enjoyable. But I subsequently learned that my fellow re- dents and mentors did not share my intrigue and comfort in de?ning the nuances of the operated heart.

Adverse drug reactions and interactions are still a major headache for healthcare professionals around the world. The US Food and Drug Administration's database recorded almost 300,000 serious adverse events in 2009 alone, of which 45,000 instances proved fatal. This updated new edition of the indispensable guide to drug interactions incorporates fresh research completed since the book's original publication by Humana Press in 2004. Additions include a new section on pharmacogenomics, a rapidly growing field that explores the genetic basis for the variability of responses to drugs. This new material reviews important polymorphisms in drug metabolizing enzymes and applies the findings to forensic interpretation, using case studies involving opiates as exemplars. Existing chapters from the first edition have in most cases been updated and reworked to reflect new data or incorporate better tables and diagrams, as well as to include recent drugs and formulations. Recent references have been inserted too. The handbook features extra material on illicit drug use, with a new chapter tackling the subject that covers cocaine, amphetamines and cannabis, among others. The section on the central nervous system also deals with a number of drugs that are abused illicitly, such as benzodiazepines, opiates flunitrazepam and GHB, while so-called 'social' drugs such as alcohol and nicotine are still discussed in the book's section on environmental and social pharmacology. Focusing as before on detailed explanation and incorporating both pharmacokinetic and pharmacodynamic drug interactions, this book will continue to be a lodestar for health and forensic professionals as well as students.

This illustrated guide to the role of the forensic anthropologist in investigating child abuse is an essential resource in one of the most contentious areas of forensic pathology. Not only does it supply a review of the literature in this field, but it illustrates the material with photographs from real cases investigated by the Harris County Institute of Forensic Sciences, which serves a population of four million people. Broken down into body regions and skeletal elements for ease of reference, the atlas facilitates the vital work performed by forensic anthropologists, who bring to the autopsy table a store of specialist knowledge that can turn a case. Despite the frequency of child fatalities (in America, 2.3per 100,000) attributed to physical abuse, merely recognizing the offense is a major forensic challenge. The tell-tale signatures of non-accidental injury can be very subtle, making it difficult to differentiate between accidental and non-accidental injury. Yet successful adjudication of a child abuse case often rests on the correct interpretation of skeletal injury. In this volume the authors guide the reader through published data regarding the mechanics and interpretation of injuries,including the agencies they indicate. The material includes discussion of the limitations faced in interpreting some injuries, where making a judgment on cause is tricky. In addition, a chapter on natural diseases affecting the bones provides a good overview of several conditions that are often invoked as 'mimics' of child abuse. Finally, this publication evinces the value of collaboration between the pathologist and the anthropologist.

This brief highlights advances in DNA technologies and their wider applications. DNA is the source of life and has been studied since a generation, but very little is known as yet. Several sophisticated technologies of the current era have laid their foundations on the principle of DNA based mechanisms. DNA based technologies are bringing a new revolution of Advanced Science and Technology. Forensic Investigation, Medical Diagnosis, Paternity Disputes, Individual Identity, Health insurance, Motor Insurance have incorporated the DNA testing and profiling technologies for settling the issues.

Juvenile homicide and fatal maltreatment remain serious and pervasive problems in the developed world and especially in the United States, where in 2005 some 1,500 children died from neglect and physical abuse. Alarming statistics such as this, as well as an upsurge in the media attention paid to all things forensic, underscore the pressing need for the utmost rigor in the scientific investigation of child abuse cases. This well timed volume is a response to the climate of public and press interest in such inquiries, where the forensic aspects of the casework generate an enormous amount of attention. The contributions cover a wide range of topics and explore many of the finer details of investigations into juvenile fatalities suspected of being abuse-related. The chapters reflect both the multi-disciplinary nature of such investigations, and also the need for law enforcement professionals to take a rounded, holistic approach to the casework involved. The motivational factors that lead many professionals enter this arena of investigation are, of course, personal and individual. However, at the core of their commitment and their work is a shared need for justice, plain and simple. Victim advocacy and protecting the rights of children, both living and deceased, remains a key impetus for those professionals who specialize in child abuse research. At the heart of this book is the aim of providing both a vital resource for investigators, and a purposeful voice for the young victims of abuse, unable as they are to stand up and speak for themselves.

The number-one guide, internationally, to all aspects of forensic isotope analysis, thoroughly updated and revised and featuring many new case studies This edition of the internationally acclaimed guide to forensic stable isotope analysis uses real-world examples to bridge discussions of the basic science, instrumentation and analytical techniques underlying forensic isotope profiling and its various technical applications. Case studies describe an array of applications, many of which were developed by the author himself. They include cases in which isotope profiling was used in murder, and drugs-related crime investigations, as well as for pharmaceutical and food authenticity control studies. Updated with coverage of exciting advances occurring in the field since the publication of the 1st edition, this 2nd edition explores innovative new techniques and applications in forensic isotope profiling, as well as key findings from original research. More than a simple update, though, this edition has been significantly revised in order to address serious problems that can arise from non-comparable and unfit-for-purpose stable isotope data. To that end, Part II has been virtually rewritten with greater emphasis now being placed on important quality control issues in stable isotope analysis in general and forensic stable isotope analysis in particular. * Written in a highly accessible style that will appeal to practitioners, researchers and students alike * Illustrates the many strengths and potential pitfalls of forensic stable isotope analysis * Uses recent case examples to bridge underlying principles with technical applications * Presents hands-on applications that let experienced researchers and forensic practitioners match problems with success stories * Includes new chapters devoted to aspects of quality control and quality assurance, including scale normalisation, the identical treatment principle, hydrogen exchange and accreditation Stable Isotope Forensics, 2nd Edition is an important professional resource for forensic scientists, law enforcement officials, public prosecutors, defence attorneys, forensic anthropologists and others for whom isotope profiling has become an indispensable tool of the trade. It is also an excellent introduction to the field for senior undergraduate and graduate forensic science students. "All students of forensic criminology, and all law enforcement officers responsible for the investigation of serious crime , will want to study this book. Wolfram highlights the value, and future potential, of Stable Isotope Forensics as an emerging powerful tool in the investigation of crime." Roy McComb, Deputy Director, Specialist Investigations, National Crime Agency (NCA), UK A single author text in these days is rare and the value of this book lies in the dedication and experience of the author which is evident in the clarity of prose, the honest illustration of evidence and the realistic practical application of the subject - it makes this a text of genuine scientific value.
