Identification of Ammunitions Used in a Lethal Robbery. Comparison Between Scanning Electron Microscopy/Energy Dispersive X-Ray Analysis (SEM-EDX) and Instrumental Neutron Activation Analysis (INAA) Measurements

CODEN: JFSCAS

Abstract

Gunshot residues (GSRs) sampled in proximity of the hole left by a bullet on the clothes of a person wounded during a homicidal robbery, have been examined by the authors, on request of the Court. These investigations have shown that gunshot residues GSRs can be considered consistent with a shot discharged by a pistol SIG SAUER, found on the crime scene, with Sellier & Bellot (S&B) ammunition. Actually, these cartridges leave residues in which tin is present together with lead and barium, as found in the examined GSRs. An evaluation of the firing distance and a comparison between scanning electron microscopy with energy dispersive X-ray analysis (SEM-EDX) and Instrumental Neutron Activation Analysis (INAA) have been also performed.
