Forensic Laboratories

Clandestine lab operators are not the mad scientists whose genius keeps them pent up in the laboratory contemplating elaborate formulas and mixing exotic chemicals. In fact, their equipment is usually simple, their chemicals household products, and their education basic. Most of the time the elements at the scene are perfectly legal to sell and own. It is only in the combination of all these elements that the lab becomes the scene of a criminal operation. Forensic Investigation of Clandestine Laboratories guides you, step-by-step, through the process of recognizing these illegal manufacturing operations. Then it shows you how to prove it in the courtroom. In non-technical language this book details: How to recognize a clandestine lab How to process the site of a clandestine lab How to analyze evidence in the examination laboratory What to derive from the physical evidence How to present the evidence in court The identification and investigation of a clandestine lab, and the successful prosecution of the perpetrators, is a team effort. A collaboration of law enforcement, forensic experts, scientists, and criminal prosecutors is required to present a case that definitively demonstrates how a group of items with legitimate uses are being used to manufacture an illegal controlled substance. Providing an understanding of how the pieces of the clandestine lab puzzle fit together, this book outlines the steps needed to identify and shut down these operations, as well as successfully prosecute the perpetrators.

Forensic science has come a long way in the past ten years. It is much more in-depth and much broader in scope, and the information gleaned from any evidence yields so much more information than it had in the past because of incredible advances in analytic instruments and crucial procedures at both the crime scene and in the lab. Many practices have gone digital, a concept not even fathomed ten years ago. And from the first collection of evidence to its lab analysis and interpretation to its final presentation in court, ethics has become an overriding guiding principle. That’s why this new edition of this classic handbook is indispensable. The Forensic Laboratory Handbook Procedures and Practice includes thirteen new chapters written by real-life practitioners who are experts in the field. It covers the tried and true topics of fingerprints, trace evidence, chemistry, biology, explosives and arson, forensic anthropology, forensic pathology, forensic documents, firearms and toolmarks. This text also addresses an array of new topics including accreditation, certification, ethics, and how insects and bugs can assist in determining many facts including a margin of time of death. In the attempt to offer a complete and comprehensive analysis The Forensic Laboratory Handbook Procedures and Practice also includes a chapter discussing the design of a laboratory. In addition, each chapter contains educational requirements needed for the discipline it covers. Complete with questions at the end of each chapter, brief author bios and real crime scene photos, this text has risen to greet the many new challenges and issues that face today’s forensic crime practitioners.

In 1992 the National Research Council issued DNA Technology in Forensic Science, a book that documented the state of the art in this emerging field. Recently, this volume was brought to worldwide attention in the murder trial of celebrity O. J. Simpson. The Evaluation of Forensic DNA Evidence reports on developments in population genetics and statistics since the original volume was published. The committee comments on statements in the original book that proved controversial or that have been misapplied in the courts. This volume offers recommendations for handling DNA samples, performing calculations, and other aspects of using DNA as a forensic toolâ€"modifying some recommendations presented in the 1992 volume. The update addresses two major areas: Determination of DNA profiles. The committee considers how laboratory errors (particularly false matches) can arise, how errors might be reduced, and how to take into account the fact that the error rate can never be reduced to zero. Interpretation of a finding that the DNA profile of a suspect or victim matches the evidence DNA. The committee addresses controversies in population genetics, exploring the problems that arise from the mixture of groups and subgroups in the American population and how this substructure can be accounted for in calculating frequencies. This volume examines statistical issues in interpreting frequencies as probabilities, including adjustments when a suspect is found through a database search. The committee includes a detailed discussion of what its recommendations would mean in the courtroom, with numerous case citations. By resolving several remaining issues in the evaluation of this increasingly important area of forensic evidence, this technical update will be important to forensic scientists and population geneticistsâ€"and helpful to attorneys, judges, and others who need to understand DNA and the law. Anyone working in laboratories and in the courts or anyone studying this issue should own this book.

A comprehensive and easy-to-read introduction to the work of the modern forensic laboratory. The authors explain in simple language the capabilities and limitations of modern forensic laboratory procedures, techniques, analyses, and interpretations. Here, the interested reader will find an understandable and fascinating introduction to the complex worlds of forensic serology DNA, chemistry, crime reconstruction, digital evidence, explosives, arson, fingerprints, firearms, tool marks, odontology, and pathology. Additional chapters address the problems of assuring quality and seeking trace evidence in the forensic laboratory.

Forensic science laboratories' reputations have increasingly come under fire. Incidents of tainted evidence, false reports, allegations of negligence, scientifically flawed testimony, or - worse yet - perjury in in-court testimony, have all served to cast a shadow over the forensic sciences. Instances of each are just a few of the quality-related charges made in the last few years. Forensic Science Under Siege is the first book to integrate and explain these problematic trends in forensic science. The issues are timely, and are approached from an investigatory, yet scholarly and research-driven, perspective. Leading experts are consulted and interviewed, including directors of highly visible forensic laboratories, as well as medical examiners and coroners who are commandeering the discussions related to these issues. Interviewees include Henry Lee, Richard Saferstein, Cyril Wecht, and many others. The ultimate consequences of all these pressures, as well as the future of forensic science, has yet to be determined. This book examines these challenges, while also exploring possible solutions (such as the formation of a forensic science consortium to address specific legislative issues). It is a must-read for all forensic scientists. Provides insight on the current state of forensic science, demands, and future direction as provided by leading experts in the field Consolidates the current state of standards and best-practices of labs across disciplines Discusses a controversial topic that must be addressed for political support and financial funding of forensic science to improve
