A spent cartridge case exhibits characteristic markings (firearm fingerprint) that can be used to identify the type and possibly make of weapon in which the cartridge was fired. This paper first briefly reviews the research into the use of discriminate analysis for the purpose of matching spent cartridge cases to specific make and model firearms. A fired projectile can also be analysed by measuring the class characteristics such as landmark, groove mark, and twist ratios. A developed Personal Computer (PC) based prototype software application called fireball will also be described in details. Finally a proposed national distributed multimedia system in Australia is outlined.
