Awwal 04, 1432 H / April 08, 2011, SPA -- A Protestant militant has been sent to prison after Northern Ireland's «cold case» detectives pinned him to the 1973 murder of a Belfast shopkeeper, according to AP. The Historical Enquiries Team, a specialist unit re-examining evidence of 3,269 unsolved murders, used modern fingerprint analysis to identify Robert Clarke as the killer. Clarke denied shooting Catholic cafe owner Alfredo Fusco point-blank in the head and body as he cowered in his cafe's stockroom on Feb. 3, 1973. But detectives were able to match police records of fingerprints found on the stockroom door to the 58-year-old Clarke. A Belfast judge sentenced Clarke to 25 years in prison Friday. Clarke previously spent 16 years behind bars for the murder and attempted murder of other Catholic civilians in 1975.
