Scientists achieve forensics’ “Holy Grail” by recovering fingerprints from fired bullets

Researchers at Maynooth University have achieved a forensic milestone by revealing fingerprints on fired bullet casings using a safe electrochemical process. The method uses mild voltage and non-toxic materials to make hidden ridges visible within seconds. Effective even on aged casings, it could help investigators connect evidence directly to a suspect rather than just a weapon.
