NCJRS Celebrates National Library Week April 12-18

National Library Week

Started in 1958, National Library Week is a nationwide observance celebrated by all types of libraries - including the NCJRS Virtual Library. NCJRS invites you to explore the breadth and scope of the NCJRS Virtual Library collection and services. With more than 220,000 collection documents and 60,000 online resources, including all known Office of Justice Programs works, it is one of the world’s largest criminal justice special collections.

We encourage your Feedback. Tell us how you use the NCJRS Virtual Library and Abstracts Database, how you access the collection, and any ways we can improve our services.

  Annotation: This research examines gunshot backspatter.
Abstract: Gunshot backspatter comprises biological material expelled backward through bullet entry holes. Crime scene investigators analyze backspatter patterns to infer wounding circumstances. An understanding of the mechanism of backspatter generation, and the relationship between spatter patterns and bullet and tissue characteristics, would enhance the predictive value of such analysis. The authors examined soft-tissue ballistic wounding responses to determine the underlying components and how these might be relevant to the generation of backspatter. The authors identified five mechanistic components to ballistic wounding (elastic, viscous, crushing, cutting, and thermal), each related to mechanical disciplines (respectively, solid mechanics, fluid mechanics, fracture mechanics, rheology, and thermodynamics). The authors identified potential roles for these five components in backspatter formation and provide a scenario whereby a sequence of events incorporating these components could lead to backspatter generation and expulsion. This research provides a framework for the mathematical representation, and subsequent computational predictive modeling, of backspatter generation and pattern formation.
