Police have offered a £20,000 reward to help catch the killer of a teenager who was murdered in Hackney 12 years ago.
Detectives are renewing their appeal for information and witnesses to the murder of Karl Hamilton, who was fatally stabbed by a gang in 2004.
Hamilton, 17, a catering assistant, was murdered when he and a group of friends got into a fight with a gang of 15 boys on the way home from a snooker game.
He was stabbed in the legs, head and body when running from the fight, and died from a wound to the chest.
Hamilton’s mother, Kim Williams, said: “We know some of you may have been young at the time but you may now have families of your own. Maybe that will help you to understand how we, Karl’s family, felt at the time and how we have suffered since his murder in 2004.
“If anyone has any information, no matter how small, please, please come forward and contact the police or Crimestoppers. If you were there at the time or have any knowledge then maybe now you feel strong enough to help us get justice for Karl.
“We still feel the loss of Karl tremendously and not a day goes past where we don’t think about him and the way our family was torn apart that night.”
The murder occurred at 10:30pm on January 10 and the case has remained open since.
At the time, 13 men were arrested in connection with the murder. Three were later charged and found not guilty of murder, while the remaining 10 were released.
Detective Chief Inspector Chris Jones, who is leading the inquiry, said: “For more than a decade Karl’s family have lived in limbo, not knowing who was responsible for taking their son, brother and grandson from them.
“We are hoping allegiances may have changed and individuals who may have previously been in fear may now feel able to speak to police and pass on any information, no matter how small or insignificant it may seem.”
Anyone with information are asked to call police on 020 8345 3734, or to remain anonymous call Crimestoppers on 0800 555 111.
