Technique to help solve US murder

A Northamptonshire Police forensic scientist is hoping his new fingerprinting technique can solve another unsolved murder in the US.

Dr John Bond has been enlisted by police in Bristol, Connecticut, to solve a decade-old murder case.
His technique detects where sweat has corroded metal on bullets, even where a fingerprint has been wiped off.
Later this month Det Garrie Dorman will fly to Northampton with bullet casings from the murder of Louis LaFontaine.
Mr LaFontaine was found shot dead at his home in Bristol on 10 February, 1998.
Det Dorman said the victim, who owned an appliance repair shop, was "well known throughout the city of Bristol, and his murder shocked the community and devastated his friends and family".

The technique can be used to find fingerprints on metal surfaces
