Many advances have been made since the publication of Drug Testing in Hair. The mid-1990s witnessed the progress in cannabis detection while the late 1990s focused on benzodiazepines detection and the applications in doping control. In more recent years, toxicologists centered on the detection in hair of a single exposure and the related applications in drug-facilitated crimes. Presenting these topics as well as the latest findings from the international community, Analytical and Practical Aspects of Drug Testing in Hair reviews all new developments, the validation of analytical procedures, and the interpretation of data. Written by well-known, international authors, this comprehensive reference provides practical coverage of the best drug testing techniques and examines the drugs themselves. Some of the applications discussed include doping, drug-facilitated crime investigating, workplace testing, and the granting of drivers' licenses. The authors describe specific drugs, such as opiates, cocaine, and cannabis, and discuss the different testing methods for them. The book also covers postmortem toxicology, pitfalls created by passive exposure, and testing for metals, including inductively coupled plasma spectrometry (ICP-MS), hair multielementary analysis, and the new speciation analysis. A complete, up-to-date resource that explains numerous drug testing techniques, Analytical and Practical Aspects of Drug Testing in Hair provides useful information for toxicologists, forensic scientists, sports medicine specialists, and pathologists.

The range of species that fall within the realm of wildlife crimes is extensive, ranging from ferns and orchids to bald eagles and great whales. Solving these crimes is rarely dependent on the testimony of witnesses or victims. An ever-increasing number of research groups are applying scientific tests to animal and plant studies alike. However, until now, whatever progress is available in this area has remained scattered through the literature. Forensic Science in Wildlife Investigations focuses on the developing test methods that can be applied to wildlife crimes. In large part, the tests described are drawn from human-based research. Edited by Adrian Linacre, a noted forensic researcher and one of the principal pioneers active in wildlife forensics, this volume collects the work of others working across the world with both plant and animal investigations. While the book contains valuable approaches that lab investigators can employ, the scientific material is written at a level that requires no more than a fundamental knowledge of biology. Any required scientific information is provided in separate boxes. Offering practical guidance, it helps investigators and lab technicians decide on best methods, including a determination of when basic microscopy is sufficient, when DNA testing should occur, and what tests or combination of tests should be executed in a particular circumstance. The text illustrates how to identify the species and geographic region of origin of an unknown sample. Demonstrating the latest methods through real-world case studies, this volume provides the direction and practical advice needed by legal and police professionals seeking to gain the evidence needed to prosecute wildlife crimes.

While one would hope that forensic scientists, investigators, and experts are intrinsically ethical by nature, the reality is that these individuals have morality as varied as the general population. These professionals confront ethical dilemmas every day, some with clear-cut protocols and others that frequently have no definitive answers. Since the publication of the first edition of Ethics and the Practice of Forensic Science, the field of forensic science has continued to see its share of controversy. This runs the gamut of news stories from investigators, lab personnel, or even lab directors falsifying results, committing perjury, admitting to fraud, to overturned convictions, questions about bias, ethics, and what constitutes an "expert" on the witness stand. This fully updated edition tackles all these issues—including some specific instances and cases of unethical behavior—and addresses such salient issues as accreditation requirements, standardization of ethical codes, examiner certification, and standards for education and training. The new edition provides: A new chapter on the "Ferguson Effect" faced by the criminal justice system The context of forensic science ethics in relation to general scientific ethics, measurement uncertainty, and ethics in criminal justice Ethical conundrums and real-world examples that forensic scientists confront every day The ethics and conduct codes of 20 different forensic and scientific professional organizations An outline of the National Academies of Science (NAS) recommendations and progress made on ethics in forensic science since the release of the NAS report Ethics and the Practice of Forensic Science, Second Edition explores the range of ethical issues facing those who work in the forensic sciences—highlights the complicated nature of ethics and decision-making at the crime scene, in the lab, and in the courts. The book serves both as an essential resource for laboratories to train their employees and as an invaluable textbook for the growing number of courses on ethics in criminal justice and forensic science curricula. Accompanying PowerPoint® slides and an Instructor’s Manual with Test Bank are available to professors upon qualifying course adoption.

In order for forensic fibre examiners to fully utilize fibre and textile evidence during their analysis, they require not only specialised forensic knowledge but also in-depth knowledge of fibres, yarns and fabrics themselves. Production, both the chemical and physical structure, and the properties of these materials is required in order to determine the value of fibre evidence. This includes knowing production figures, fashion changes, sudden arrivals of new materials, dye variability, and numerous other factors that may have a bearing on the information obtained. Fully updated with the latest advances, Forensic Examination of Fibres, Third Edition continues in the tradition of the First (1992) and Second Editions (1999) as the premier text on the subject of forensic fibre analysis. The international team of contributing authors detail the recovery of the evidence—through the different stages of laboratory examination—to the evaluation of the meaning of findings. The coverage has been considerably expanded, and all material, has been revised and wholly updated. Topics covered include examining damaged textiles, infrared microspectroscopy and thin layer chomatography, and colour analyses.? This edition also highlights the critical role of quality assurance in ensuring the reliability of the technical observations and results, and, in doing so, looks at the implications of supervisory managers and labs in the accurate and responsible analysis of such evidence. Features include: Outlining evidentiary process from collecting and preserving the evidence at the crime scene through the laboratory analysis of fibres Detailing the latest developments and emerging technologies including Kevlar and other such advances in fibre technology Coverage of a broad array of fibres both, natural (cellulose, protein, and mineral) and man-made fibres including synthetic, inorganic and regenerated Forensic Examination of Fibres, Third Edition is a much-needed update to the classic book, serving as an indispensable reference to crime scene technicians, laboratory forensic scientists and microscopists, students in police, forensic, and justice science programs.
