Firearms

Numerous crime laboratories have witnessed a surge in gun-related evidence submissions, leading to an increased demand for DNA testing and entry into the National Integrated Ballistic Information Network (NIBIN) for firearms-related investigations. Simultaneously, the forensic value of firearms analysis has substantially grown, owing to advancements in DNA technology and the expansion of the NIBIN database. Consequently, several forensic labs have established dedicated units specifically focused on comprehensive firearms analysis.

The Phoenix Police Department (PPD) made a department-wide cultural change in evidence handling, screening, and processing strategies in support of Crime Gun Intelligence Center goals. In addition, the Firearms Section of the PPD Crime Laboratory has validated and implemented a 3D topographical Virtual Comparison Microscopy (VCM) system. The presenters will discuss how the addition of 3D VCM technology in the laboratory and the incorporation of 3D technologies into the NIBIN system has bolstered their ability to provide the best results possible to our customers.
