The examination of human hairs in the forensic science setting is a highly specialist forensic discipline. To date the topic has not been covered in a single volume in which all aspects of hair examination are brought together. In this volume an international group of authors have dealt with all aspects of the examination of human hair. The volume opens with the basic foundation accidence covering the physiology, growth and structure of hair. Forensic specific aspects of hair structure are then dealt with and a protocol for examination is presented. The remaining chapters deal with non microscopy approaches to hair examination covering historical and contemporary knowledge. These chapters include biochemical approaches to hair examination, the use of elemental analysis, the analysis of cosmetic treatments, the analysis of hairs for drugs and the use of DNA analysis. In the final chapter the value of hair examination as evidence is assessed. The book will be of value to students forensic science, to members of the legal profession and to practitioners of forensic science. Written in an open accessible style it promises to be the standard text for human hair for the foreseeable future.

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.

India has been identified as one of the twelve mega-biodiversity nations of the world. In India, wildlife is protected under the Wildlife (Protection) Act-1972 and India is also a party to Convention on International Trade in Endangered Species (CITES). However, despite such good legislation, poaching has increased over the years, decimating the populations of wild animals. This is attributed to the lack of adequate species identification techniques and data base that can be used to identify species from confiscated items. Thus most of the wildlife offence cases fail in court of law. Hair is found invariably in poaching cases related to mammals and the value of hair evidence is well acknowledged in forensic analysis. An attempt was made to fill the aforesaid lacuna and the present study was undertaken to characterise hair of Artiodactyl (Bovids and Cervids) species listed under Schedule-I of Wildlife (Protection) Act-1972, through microscopy, Keratin profiling and mitochondrial DNA analysis. The findings of the microscopic examination, keratin and DNA analysis will help immensely in identification of species from exhibits of wildlife offence cases

It fills a void in the resources available to researchers and practitioners in forensic hair examination by providing photographic archetypes for the microscopic characteristics of human hair and the variates of the characteristics seen in forensic examinations, including curl; color; pigment distribution and density; cortical fusi; and ovoid bodies. These illustrations provide a uniform basis for describing the characteristics and their variations for forensic professionals in differing geographical areas. The documentation of hair characteristics using the scoring system outlined in this atlas allows researchers to develop data regarding the frequency of characteristics within the hairs of one or more individuals and the assessment of whether certain hair characteristics are co-dependent.

The identification and quantification of material present and collected at a crime scene are critical requirements in investigative analyses. Forensic analysts use a variety of tools and techniques to achieve this, many of which use light. Light is not always the forensic analyst’s friend however, as light can degrade samples and alter results. This book details the analysis of a range of molecular systems by light-based techniques relevant to forensic science, as well as the negative effects of light in the degradation of forensic evidence, such as the breakage of DNA linkages during DNA profiling. The introductory chapters explain how chemiluminescence and fluorescence can be used to visualise samples and the advantages and limitations of available technologies. They also discuss the limitations of our knowledge about how light could alter the physical nature of materials, for example by breaking DNA linkages during DNA profiling or by modifying molecular structures of polymers and illicit drugs. The book then explains how to detect, analyse and interpret evidence from materials such as illicit drugs, agents of bioterrorism, and textiles, using light-based techniques from microscopy to surface enhanced Raman spectroscopy. Edited by active photobiological and forensic scientists, this book will be of interest to students and researchers in the fields of photochemistry, photobiology, toxicology and forensic science.

Josiah Sutton was convicted of rape. He was five inches shorter and 65 pounds lighter than the suspect described by the victim, but at trial a lab analyst testified that his DNA was found at the crime scene. His case looked like many others—arrest, swab, match, conviction. But there was just one problem—Sutton was innocent. We think of DNA forensics as an infallible science that catches the bad guys and exonerates the innocent. But when the science goes rogue, it can lead to a gross miscarriage of justice. Erin Murphy exposes the dark side of forensic DNA testing: crime labs that receive little oversight and produce inconsistent results; prosecutors who push to test smaller and poorer-quality samples, inviting error and bias; law-enforcement officers who compile massive, unregulated, and racially skewed DNA databases; and industry lobbyists who push policies of “stop and spit.” DNA testing is rightly seen as a transformative technological breakthrough, but we should be wary of placing such a powerful weapon in the hands of the same broken criminal justice system that has produced mass incarceration, privileged government interests over personal privacy, and all too often enforced the law in a biased or unjust manner. Inside the Cell exposes the truth about forensic DNA, and shows us what it will take to harness the power of genetic identification in service of accuracy and fairness.
