The Use of Unburned Propellant Powder for Shooting-Distance Determination. Part I: Infrared Luminescence

Shooting-distance determination is a standard question in forensic cases of shooting accidents, suicides or homicides for case reconstruction purposes. In most short to very short gun-to-target distance cases, wound-ballistics can answer to this question due to tissue damage/deformation caused by the shooting gas pressure. This gas pressure drops with increasing gun-to-target distance; thus, at higher distances (bigger than a few centimeters, depending on the firearm), its energy is too low to influence tissue morphology [1,2].
