Michael Ofori, 35, was shot dead in front of his estranged wife in a suspected case of mistaken identity.
He was chatting to Sabine Bonsu in his Mercedes in Oslac Road, Catford, southeast London, when an unknown gunman opened fire just after midnight on June 23, 2010.
Mr Ofori, the cousin of former England rugby player Paul Sackey and the father of a young girl, was hit once in the head and once in the arm.
The investigation led detectives to suspect he was the innocent victim of a 'tit-for-tat' series of shootings between two rival groups in the months before the murder.
Police charged five men with murder: Nicholas Allon-McVytie, Sahid Sule, Kraig Isaacs, Jules Brown and Nathaniel Valton.
The prosecution case was that the intended target of the shooting was 24 year-old Perry Walters, who was either in the same road or very close by at the time of the attack.
Sule was said to have coordinated the murder using his false name, with Brown acting as the lookout, Allon-McVytie as the getaway driver using a white van bought under a false name, and Valton as the gunman.
The case relied heavily on CCTV and cell-site analysis to piece together the movements of the killers before and after the murder.
On October 18, 2011, following a trial at the Old Bailey, Allon-McVytie, 23, of Vanguard Street, Deptford, southeast London, and Sule, 23, of no fixed address, were convicted of murder. Isaacs, 21, was acquitted.
Sule and Allon McVytie were both jailed for life with a minimum of 28 years to serve before parole.
On May 15, 2012, following a second trial at the same court, Brown, 25, of Eversleigh Road, Upton Park, east London, was convicted of murder and jailed for life with a minimum of 26 years before parole.
Nathaniel Valton, 22, of Adolphus Street, Deptford, was cleared of murder.
Detective Inspector Andy Muir, Trident, said of Sule, Brown and Allon-McVytie: “These men lived their lives according to their criminal activities which regularly led them to be involved in violent disputes with other criminals.
"Their activities blighted local communities and on this occasion led them to the decision to plan and commit murder. Tragically they murdered Michael Ofori who was not their associate and was in the wrong place at the wrong time.
"Michael’s friends and family have been left devastated by his death and his young daughter has been left without her father. I hope that today’s convictions go some way in providing them with comfort.”
