Abstract

Latent fingerprints from cartridge cases are of great evidential value, allowing investigators to link a person to the scene of a crime. Many techniques have been reported to be effective in developing fingerprints on cartridge cases including gun blue, a category B process which coats the cartridge case in a dark CuSe alloy. Dove introduced the concept of the electrodeposition of gun blue in 2014, hypothesising that the application of a potential difference would cause preferential deposition of the gun blue onto the cartridge case. While the method has proven quite effective when compared to conventional techniques such as CA fuming followed by BY40, it has not yet been compared to CA fuming and powdering. Additionally, it’s effect on subsequent DNA recovery has not been reported.
