Spectroscopic (analytical) approach to gunshot residue analysis for shooting distance estimation: a systematic review

Abstract Background The determination of the shooting distance using gunshot residue (GSR) analysis is crucial in the investigation and reconstruction of firearm-related crimes. However, the conventional chemographic method for GSR analysis is destructive and has limited sensitivity and selectivity....
