In recent years, the use of illegally produced firearms has increased exponentially worldwide. These are often cheap, nonstandard firearms that defy known classification and identification criteria. The use of unusual firearms in crimes has frequently led to unpredictable and misleading reconstruction of shooting incidents. In this book, internationally known forensic firearm expert, J.K. Sinha, presents a detailed forensic study of unusual firearms, with the goal of helping crime-scene investigators to minimize erroneous conclusions in cases where these types of firearms are used. Based on his extensive experimentation with more than 1,000 nonstandard firearms, the author identifies new class characteristic parameters needed to establish linkage of projectiles with irregular rifled and smoothbore barrels. The book begins with an introduction to unusual firearms and proceeds to discuss forensic investigation of fired bullets, medico-legal evidence, barrel marks on fired shots, and investigation of fired cartridges and shot charge. Chapters also cover topics such as timing of firing, unusual rifling marks, shooter identification, and unusual bullet hole evaluations. Providing concise yet complete techniques for making forensic analyses and conclusions, this is the first book of its kind to critically examine the use of unusual, nonstandard firearms in perpetrating crimes. It is intended for professionals and academicians working in the field: forensic firearm experts and consultants, forensic medicine professionals and medico-legal experts, prosecution and defense attorneys, enforcement agencies and judiciary, university students and researchers studying forensic science, forensic medicine, criminology and law.

Chemical Analysis of Firearms, Ammunition, and Gunshot Residue, Second Edition continues in the tradition of the popular first edition, filling the void in forensic texts on the subject. While most books on firearms focus solely on the physical aspects of firearms, this book addresses forensic issues relating to the chemical aspects of firearms and ammunition. It draws on the latest published literature including books, scientific papers, technical reports, manufacturer’s literature, newspaper articles, and personal observations and research conducted by the author. This edition is fully updated, introducing the history and development of firearms and ammunition including advances in the chemical analysis of them. Several changes in primer compositions and the particle classification system are addressed with new techniques added on evidence collection and testing methods. Coverage details chemical aspects of forensic firearms casework with particular emphasis on the detection of gunshot residues (GSR), firearm discharge residues (FDR), and cartridge discharge residues (CDR) on a suspect’s skin and clothing surfaces. Two new chapters have been added. One deals with unusual firearms case while the other summarizes a controversial, high-profile Australian case involving inorganic and organic gunshot residue, highlighting the dangers of incorrect forensic evidence and the increased need for careful training of forensic scientists. Fully updated to reflect the latest techniques and tests for particle and chemical classification Provides a complete history of firearms and ammunition development as well as advances in the chemical analysis involved in forensic firearm casework Features a one-of-a-kind chapter on processing suspects, a crucial component in many firearms and explosives residue cases The book will serves as a useful to forensic chemists, investigators, ballistics experts, among other professionals serving in a variety of forensic disciplines.

While it has always been legal for a citizen in the United States to manufacture their own firearm, the sale and distribution of such items is illegal under current U.S. law. The primary impediment to individuals making their own weapons has been access to the tooling and machinery required to convert raw materials into finished parts for assembly. However, in the last fifteen years this paradigm has changed drastically. Home builders and companies have emerged to support individuals who choose to produce their own firearm. Kits with receivers and gun components are available for hobbyists, as are 3-D printable gun designs, downloadable from the Internet in some cases. This phenomenon has led to the term ghost guns: firearms whose existence is not reported to any third party and therefore whose existence is unknown and, largely, untraceable. A Field Guide to Ghost Guns: For Police and Forensic Investigators provides a useful brief for field investigators on the technical aspects of the self-made firearm, so-called "ghost guns. The first book to focus on the emergent issue of ghost guns, coverage addresses the history of firearms making and manufacture in the U.S.—including regulated and nonregulated manufacturing, details firearm components and accessories, how to assemble a Firearm, an overview of common Types of ghost guns, and investigative considerations. Though there have been increased calls to regulate guns in the wake of numerous mass shootings, the proliferation of ghost guns—and their increasing use in crimes—would likely require additional laws and regulatory measures. Since there are few knowledgeable firearm practitioners in the field, who can render qualified opinions on the subject, author Robb Walker has taken a practical, pragmatic approach to the topic. The book defines terminology, provides photographs, and explains the concepts surrounding homemade firearm in clear, easy to understand terms. Key Features: Addresses the technology and technical aspects in creating, assembling, and/or modifying homemade firearms—both printable and assembled from pre-fabricated components Discusses the rationale and motivations behind making one’s own firearm Outlines what is currently legal and illegal under U.S. law, providing indicators for investigators for illegally configured firearms A Field Guide to Ghost Guns addresses the pressing need for a practical reference on the topic. The book provides police investigators and forensic ballistics experts a useful aid to understand legal aspects and to identify ghost guns, and the paraphernalia—tooling and machinery, and otherwise—indicative of gun making in a non-formal, factory setting.

Battlefield Forensics for Persian Gulf States provides an illustrative reference of various weapons, toolmarks, headstamps, and other traits in order to identify the origins of a variety of guns, casings, and ammunition that can be found in the Middle East. Various conflicts in the region have led to innumerable weapons being used throughout the years. The lead author, Don Mikko, has investigated and examined firearms related items of evidence in countless crime scenes throughout the world. As the Chief of the Firearms Branch at the United States Army Criminal Investigation Laboratory (USACIL), Fort Gillem, Georgia, he recruited, trained, and competency tested military contractors deploying to various combat related areas of the world, those providing forensic firearm and toolmark identification support to local commanders. What was learned was that various foreign weapons and ammunition were being utilized in conflicts and by opposing forces. This book educates readers on the technical data for different types of firearms, ammunition, countries of origin, proof marks, penetrator information and the typical firearm markings imparted on fired cartridge cases, such as breech-face, firing pin, ejector, and extractor markings. Forensics and biometrics within the Persian Gulf have been leveraged since the early 1990s and many of the firearms and types of ammunition covered in this handbook are addressed in an effort to assist those on the ground who are required to be able to identify such items in various scenarios. The information contained within the book has proven to be effective on the battlefield and has helped shape combat operations. This handbook will serve as a useful reference not only to assist military and contractor personnel within the various combat locations but will also prove to be beneficial for law-enforcement, crime laboratory personnel, forensic firearm and toolmark examiners, crime scene investigators, students, practitioners, and civilian personnel throughout the world.
