James Kamara, a dad-of-two, was killed in a drive-by shooting in Broomhall in July 2009.
The 22-year-old was shot seven times in his chest while he was sat in a car in Brunswick Street saying his goodbyes to friends before he left Sheffield to start a new life in another city.
South Yorkshire Police believe James was killed as part of a bitter feud between rival gangs operating in Sheffield at that time – the S3 gang from Burngreave and Pitsmoor and the WS10 ‘Squaremen’ from Broomhall.
James died in a hail of bullets 90 minutes after the rival gangs clashed in Eldon Street, Devonshire Green.
Detectives who investigated the case believe a leading member of the Squaremen had been the intended target of the attack and that James was in the wrong place at the wrong time.
A masked man opened fire from a passing Vauxhall Vectra, hitting James seven times and injuring three others.
Four men were charged over the death, with three arrested in Liverpool and one in Spain, but they walked free from court after being found not guilty following a trial.
The shooting was described in court as a 'premeditated and cold-blooded killing'.
After the trial of the four men, South Yorkshire Police said: “The case remains open and is regularly monitored and reviewed by the force's major incident team.”
