The paper describes a developed multimedia database system for ballistics firearm identification for Australian Police. 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. 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 and a national distributed system through the Internet are discussed in details.
