Book Description
ABSTRACT: This thesis is an examination of a firearm identification system that creates a three-dimensional image of a bullet in order to record the depth and length of striations occurring along the bullet's surface. Ballistics evidence is an area of forensics in great need of further development. The advent of more sophisticated firearms such as semi-automatic and automatic weapons has increased the need for a matching system that connects bullets found at crime scenes with suspect guns. In the past, control bullets matching ones found at the crime scene have been test fired and then examined by a comparison microscope for similarities with the evidence bullet. The purpose of this thesis is to examine data collected by an emerging system that uses three-dimensional technology by way of a laser and convex mirrors to create a digitized representation of the lands and grooves of a bullet.

Book Description
The Bureau of Alcohol, Tobacco and Firearms (ATF) laboratories is applying the new technology of computerized image analysis for the identification of bullets and cartridge casings recovered in open cases, and to a database of test fired weapons. The Integrated Ballistic Identification System (IBIS) accomplishes these comparisons in minutes, when the same task using conventional microscopical techniques would require weeks to carefully sort through the firearm evidence. The networking of remote Data Acquisition Stations (DAS) can build a regional firearms evidence database, making the IBIS a powerful resource for the investigation of violent firearm crimes from multiple jurisdictions. A technical overview of the IBIS image acquisition hardware, image storage, case data input, "surface signature" analysis, and correlation scoring to an image database is reported.

Book Description
Since the early 1990's, the idea of automated systems for the comparison of microscopic firearms evidence has received considerable attention. The main objective of such systems is to enable the analysis of large amounts of evidence, therefore, transforming the comparison of firearms evidence from an evidence verification tool into a crime-fighting tool. Two such systems have been widely used in United States forensic laboratories; namely, the Integrated Ballistics Identification System (IBIS) (1) and DRUGFIRE (2) Both IBIS and DRUGFIRE have in common the fact that their characterization of a specimen is based on a two-dimensional (2D) representation of the specimen's surface.

Book Description
Ballistic Imaging assesses the state of computer-based imaging technology in forensic firearms identification. The book evaluates the current law enforcement database of images of crime-related cartridge cases and bullets and recommends ways to improve the usefulness of the technology for suggesting leads in criminal investigations. It also advises against the construction of a national reference database that would include images from test-fires of every newly manufactured or imported firearm in the United States. The book also suggests further research on an alternate method for generating an investigative lead to the location where a gun was first sold: "microstamping," the direct imprinting of unique identifiers on firearm parts or ammunition.

In the wake of the Daubert ruling, the use of forensic toolmark evidence in court has been problematic, in that the conclusions of forensic scientists as to toolmark origin often lack scientifically sound statistical proof. In the Color Atlas of Forensic Toolmark Identification, noted forensic expert Nicholas Petraco helps move toolmark examination

Book Description
Automated Ballistic Identification Systems provides a comprehensive reference to automated ballistics identification, detailing for forensic specialists what automated systems and instruments are available, how they work and what they are best used for. As the primary duties of a Firearm and Tool Mark Examiner are to identify, collect, preserve, examine and interpret the ballistic evidence associated with criminal acts, this is an ideal reference that not only includes tactics on how to properly use optical, electronic, measurement and analytical instruments to process and analyze evidence, but also discusses the limitations of said instruments. Provides forensic technicians with in-depth reviews of existing technologies, their capabilities and how to utilize the technologies in investigations and research Includes coverage of global ballistic systems used, such as Alias, IBIS, Lucia, Balistika, Papillon and Fireball Includes a foreword/endorsement from Robert Thompson of N.I.S.T., who has an extensive background in firearms and tool mark examination, and is a highly respected member of the AFTE (Association of Firearms and Tool Mark Examiners)

Book Description
Forensic science includes all aspects of investigating a crime, including: chemistry, biology and physics, and also incorporates countless other specialties. Today, the service offered under the guise of "forensic science’ includes specialties from virtually all aspects of modern science, medicine, engineering, mathematics and technology. The Encyclopedia of Forensic Sciences, Second Edition, Four Volume Set is a reference source that will inform both the crime scene worker and the laboratory worker of each other’s protocols, procedures and limitations. Written by leading scientists in each area, every article is peer reviewed to establish clarity, accuracy, and comprehensiveness. As reflected in the specialties of its Editorial Board, the contents covers the core theories, methods and techniques employed by forensic scientists – and applications of these that are used in forensic analysis. This 4-volume set represents a 30% growth in articles from the first edition, with a particular increase in coverage of DNA and digital forensics Includes an international collection of contributors The second edition features a new 21-member editorial board, half of which are internationally based Includes over 300 articles, approximately 10pp on average Each article features a) suggested readings which point readers to additional sources for more information, b) a list of related Web sites, c) a 5-10 word glossary and definition paragraph, and d) cross-references to related articles in the encyclopedia Available online via SciVerse ScienceDirect. Please visit www.info.sciencedirect.com for more information This new edition continues the reputation of the first edition, which was awarded an Honorable Mention in the prestigious Dartmouth Medal competition for 2001. This award honors the creation of reference works of outstanding quality and significance, and is sponsored by the RUSA Committee of the American Library Association

Book Description
Forensic Firearm Examination provides the reader with a thorough understanding of theory, application, and process of firearm comparison. It is essential in the field of forensic firearm examination to not only understand the marks that examiners are observing, but more importantly learn where these marks come from during the manufacturing process. This book explores the various machining techniques utilized in the manufacturing process and the resulting marks left by those tools. This information will equip the examiner with the knowledge to answer questions posed by the legal system regarding the uniqueness or potential similarity of marks on firearms imparted to fired bullets and cartridge cases. Intended primarily for firearm and tool mark examiners, this valuable resource serves as a primary requirement for the training of firearm and tool mark examiners. Other forensic science disciplines who rely on pattern matching as a primary determining factor whether or not two objects may share a common source would also find utility in this work. Finally, it will be a valuable resource for attorneys who are seeking to understand better the scientific aspects of firearm identification. Written by a foremost expert in the field, Forensic Firearm Examination explores specific firearm manufacturing techniques and the resulting marks, which has not been covered in any book publication. Chris Monturo has over 23 years of experience as forensic firearm and tool mark examiner. Additionally, he is a distinguished member of the Association of Firearm and Tool Mark Examiners (AFTE), a past member of the Scientific Working Group for Firearm and Tool Marks (SWGGUN), past member of the Organization of Scientific Area Subcommittees (OSAC) for firearm and tool marks and has instructed courses in machining for the firearm examiner in the United States and Internationally. Provides reader with a thorough understanding of theory, application, and process of firearm identification Topics include the manufacturing process of all components that interact with the bullet or case during firing, the nature of manufacturing and potential pitfalls, such as subclass
