Utilization of Organic Constituents into GSR Analysis

Utilization of Organic Constituents into GSR Analysis

Suzanne Bell of West Virginia University (WVU, Departments of Chemistry and Forensic Science) presents on the utilization of organic constituents into gunshot residue analysis. This innovative technology involves experimental and modeling studies used to elucidate characteristics of skin permeation of five compounds present in OGSR. Results showed that OGSR residues should be detectable on skin for many hours after a firing event of as few as one or two shots, with detection capability being a function of the efficacy of sampling and sample preparation and the instrumental method employed. The permeation rates of the OGSR compounds were sufficiently different to suggest the potential to develop methods to approximate time-since-deposition.
