The mother of a man murdered in Hornsey two years ago is appealing for his killers to turn themselves in.

Jerome Vassell, 19, was shot in the head in October 2006, in the car park of the West Indian Cultural Centre in Clarendon Road.

He spent five months in hospital and was discharged in March 2007 with severe brain damage, partial paralysis and communication problems.

In December last year Mr Vassell collapsed at his home in Haringey Road, Tottenham, and died.

Now his mother, who does not wish to be named, has said she has forgiven his killers and is encouraging them to come forward.

She said: "Jerome was a devoted father and loving member of the family. He was an intelligent, energetic, lively, charming and powerful character with a good nature and he loved life.

"I have forgiven you already and I know sometimes society makes you do things you don't mean to do.

She added: "So we as a family are calling on everyone, including the perpetrator. Clear your conscience, come forward with any information no matter how irrelevant you think it may be."

Police are treating Mr Vassell's death as murder and they believe he was involved in an argument with a gang of black men outside the cultural centre the night he was shot.

They are offering a £20,000 reward for information leading to the conviction of his killers, who two years on have not been found.

Detective Chief Inspector Fiona Mallon, who is in charge of the investigation, said: "Two years have now passed since Jerome was attacked. We believe there are still people who have yet to come forward who have information about what happened and we would ask them to please contact us.

"We are particularly interested in hearing from anyone who attended the West Indian Cultural Centre on the evening of Friday, October 27, 2006 or witnessed the shooting in the car park outside shortly before 1am on October 28.

"Hundreds of people were there that night attending various events and we would like to talk to anyone who may be able to help with our enquiries."

Anyone with information is asked to contact the incident room on 020 8733 4704 or Crimestoppers anonymously on 0800 555 111.
