Abstract

Does this gun shoot? When firearms are found on a crime scene, investigators frequently sniff the canon aperture in order to identify which of them could have been used recently. This technique gives useful information but is not based on a scientific and validated methodology. In order to solve this problem, the French Gendarmerie Forensic Research Institute has developed and validated an analytical method based on extraction of aromatic hydrocarbon residues by solid phase micro-extraction (SPME), followed by gas chromatography coupled with mass spectrometry (GC/MS).
