Justice Today Podcast: Closing Cases Using Gunshot Residue

Date Published
May 2024

In this episode, the Justice Today podcast discusses how cases are closed using gunshot residue.


This episode of the Justice Today Podcast discusses how cases are closed using gunshot residue. In cases where definitive evidence (such as DNA) cannot link an individual to a crime, law enforcement relies on other evidence to build the burden of proof. National Institute of Justice graduate research fellow Dr. Shelby Khandasammy developed a tool to analyze organic gunshot residue and distinguish between different firearms calibers and manufacturers. She joins Marie Garcia, office director for the Office of Criminal Justice Systems at NIJ, to talk about her work and experience as a research fellow.
