Firearm Databases and Automated Search Systems

Whether a firearm is used by the same criminal or shared between members of a criminal enterprise, firearm evidence can link a person or persons to multiple crimes. The problem in doing so is the difficulty in searching and comparing numerous bullets or casings. If the crimes were committed across multiple jurisdictions, then the task becomes even more involved. The National Integration Ballistic Information Network (NIBIN) automates ballistics evaluations and provides investigative leads by revealing connections between crimes in which the same firearm is used. Before NIBIN, irearms examiners had to manually search and compare bullets and casings between crimes; this was extremely labor intensive. Firearms examiners scan cartridge cases and the images are compared against the database and correlations are reported. More than 1000 NIBIN users have been certified to use the system and to date NIBIN partners have confirmed more than 50,000 NIBIN hits.
