Just Quick Screening Methods for Firearm Discharge Residues_2020NIJRandD_127

In this episode of the 2020 R&D Season, Just Science interviews Dr. Tatiana Trejos, Assistant Professor of the Department of Forensic and Investigative Sciences at West Virginia University, about the rapid detection of organic and inorganic gunshot residue. Speed and accuracy are vital when it comes to the analysis of gunshot residue. Dr. Trejos and her team are working on a comprehensive method for studying both organic and inorganic gunshot residue utilizing laser-induced breakdown spectroscopy. This method focuses on providing accurate results, reducing wait time, and preserving the evidence. Listen along as she discusses chemometrics and a novel tool for analyzing organic and inorganic gunshot residue in this episode of Just Science. This season is funded by the National Institute of Justice’s Forensic Technology Center of Excellence.
