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.
This book is the definitive text for forensic scientists, police and lawyers who may be involved with the use of textile fibres to provide evidence in criminal cases. While covering the subject in detail from recovery of the evidence, through the different stages of laboratory examination, to evaulating the meaning of findings, it is written in such a way that it should be interesting and understandable to the beginner and to the layman, as well as to the expert.

The Daubert trilogy of U.S. Supreme Court cases has established that scientific expert testimony must be based on science grounded in empirical research. As such, greater scrutiny is being placed on questioned document examination generally, and handwriting comparison in particular. Bridging the gap between theory and practice, The Neuroscience of Handwriting: Applications in Forensic Document Examination examines the essential neuroscientific principles underlying normal and pathological hand motor control and handwriting. Topics discussed include: Fundamental principles in the neuroanatomy and neurochemistry of hand motor control and their application to research in handwriting The epidemiology, pathophysiology, and motor characteristics of neurogenerative diseases such as Parkinson’s, Huntington’s, Alzheimer’s, multiple sclerosis, essential tremor, and motor neuron disease and their effects on handwriting Psychotropic medications prescribed for depression, bipolar disorder, and psychosis; their mechanisms of action; and their effect on motor behavior and handwriting The impact of substance abuse on handwriting An overview of the aging process and its effects on motor control and handwriting The kinematic approach and new findings on the kinematic analyses of genuine, disguised, and forged signatures The authors’ laboratory research on authentic and forged signatures An essential resource for professionals and researchers in the forensic documentation examination and legal communities, this volume provides a window on the scientific process of signature and handwriting authentication, integrating the extensive research on neural processes and exploring how disease, medication, and advanced age alter these processes.
While gun design has undergone only minimal change over the centuries, investigative tools surrounding firearm use have grown significantly in sophistication. Now in its third edition, Firearms, the Law, and Forensic Ballistics has been updated to reflect recently published research and new technology developed since the last volume. Beginning with a discussion of the development of arms and ammunition from the fourteenth century to the present day, this book examines: Firearms laws around the world, including legal challenges raised in the U.S. by the Daubert decision Firearms manufacturing processes, the mechanisms of various firearms, and the linking of a particular bullet or spent cartridge with a suspected weapon The origins and development of new science in firearms, including controversies, pioneers, and an exposé of the "quack" purveyors of pseudo-science Internal, external, and terminal (wound) ballistics The nature, composition, and analytical detection of discharge residue left on a suspect The role of the ballistics expert at all stages of a case, ranging from the scene of the shooting incident, the post mortem examinations, the examination and testing of exhibits at the laboratory, and the presentation of evidence in court Recently introduced computer search techniques applied to captured and digitally stored images of marks left on fired bullets and spent cartridge cases Manual microscopic comparison work and computer-based searches on digital images of bullet and cartridge case marks to determine if a particular weapon has been fired in previous cases Written by an expert with more than 50 years of experience using and handling firearms, this text is enhanced with nearly 250 illustrations, making it a premier guide to the fundamentals of firearms and related evidentiary considerations.

Crime scene investigation involves the use and integration of scientific methods, physical evidence, and deductive reasoning in order to determine and establish the series of events surrounding a crime. The quality of the immediate crime scene response and the manner in which the crime scene is examined are critical to the success of the investigation. Evidence that is missed or corrupted by incomplete or improper handling can have a devastating effect on a case and keep justice from being served. The Practice of Crime Scene Investigation covers numerous aspects of crime scene investigation, including the latest in education and training, quality systems accreditation, quality assurance, and the application of specialist scientific disciplines to crime. The book discusses a range of basic and advanced techniques such as fingerprinting, dealing with trauma victims, photofit technology, the role of the pathologist and ballistic expert, and signal processing. It also reviews specialist crime scene examinations including clandestine laboratories, drug operations, arson, and explosives.
