British scientist helps with Georgia cold case - Examiner.com

"Fingerprint evidence in a double homicide nine years ago in southeast Georgia has been revealed through a technique developed by a British forensic scientist who says his method could help detect latent prints on bullets or terrorist bombs."

"Kingsland Police Chief Darryl Griffis read about Bond's work and sent a cold-case detective, Christopher King to England with four shell casings found after two auto-title pawn business managers were robbed and fatally shot Dec. 1, 1999. King believes one of the casings revealed enough detail of a fingerprint ridge to provide an identification."
This article goes on to say traditional latent extraction methods of dusting and fuming had failed on these casings. Dr Bond is averaging a call a day about potential USA cases.

"New study will make criminals sweat
Dr John Bond, a researcher at the University of Leicester, has developed a method that enables scientists to 'visualise fingerprints' even after the print itself has been removed. He and colleagues conducted a study into the way fingerprints can corrode metal surfaces. The technique can enhance after firing a fingerprint that has been deposited on a small calibre metal cartridge case before it is fired." ... snip.... goes on to explain how salts excreted through fingertip pores are detected & an
