Rocky Dawson murder: Family in plea to help find motive
The family of a man shot dead in front of his two children are appealing for help to find out why he was murdered.
Rocky Dawson, 24, was shot several times in the back as he put the children in his car in Hornchurch, east London, in 2006.
Two people have been convicted and jailed for what police have described as a "contract killing".
But his family and police say a motive has never been established and that others were involved in the murder.
Mr Dawson's mother, Candy, said: "Even though Rocky was brutally murdered seven years ago I will never stop seeking justice for him.
"There are still people out there walking about freely and looking forward to Christmas who were involved and know the reason why Rocky was shot dead in front of my grandchildren."
Mr Dawson had been standing close to his car with his two young children - a girl, then aged six, and a boy aged two - seated inside, when a 4x4 vehicle drove past and shots were fired.
Christopher Pearman, of Waltham Abbey, Essex, was convicted of murder in 2007. He was jailed for life and was ordered to serve a minimum of 23 years.
James Tomkins had fled to Spain but was extradited and jailed for life for murder in 2011. He was ordered to serve a minimum of 33 years.
Det Insp Mark Lawson said: "We already have two men serving lengthy jail terms for Rocky's murder but the motive for his killing has never been fully established - it may have been a case of mistaken identity.
"What we do know is that this was a contract killing and there are likely to be people involved in organising the murder who have yet to be brought to justice."
He added: "As Christmas approaches, Rocky's children must again face the festive season without their father and Candy is desperate to understand exactly what happened to her son and see all those responsible behind bars."
