Tyrone Rowe murder: Grandmother appeals for justice
The grandmother of a teenager who was murdered more than a decade ago has said her family "are unable to move on" with their lives.
Tyrone Rowe, 18, was shot dead in Tottenham, north London in October 2001 while he was in a car with three friends.
His grandmother Ida Mclarty appealed for help to catch his killers.
A £20,000 reward is being offered for information leading to their arrest and prosecution.
Ms Mclarty said: "I want people who know anything about my grandson's death to come forward.
"There are people who know what happened that night.
"We have spent the last 11 years not knowing what happened or why Tyrone was killed.
"My family are unable to move on with our lives."
Scotland Yard said Mr Rowe and his friends were travelling in a red Ford Fiesta at around 01:30 GMT, apparently looking for a party, when they were confronted by a group of six or seven black men.
At least two of them opened fire with handguns. Mr Rowe was hit in the head and hand and died on 11 October, police said.
The driver of the car was shot in the chest, but survived.
Three of the attackers drove off in a green people carrier, possibly a Chrysler Voyager, towards Turnpike Lane.
Det Ch Insp Kenny McDonald said: "It has been 11 years since Tyrone was brutally murdered in front of his friends.
"He was only 18 years old when he died and his family are still struggling to come to terms with his death, not least because no one has been brought to justice.
"I firmly believe there are people in the community who have important information that will assist the investigation," he said.
