Karl Hamilton murder: £20k reward offered for information
Detectives are offering a £20,000 reward for information leading to the prosecution of whoever killed an east London teenager 12 years after his murder.
Catering assistant Karl Hamilton was 17 when he was fatally stabbed on the evening of 10 January 2004.
He was attacked by a group of about 15 youths in Hackney.
Karl's mother, Kim Williams, said her family was "torn apart" the day her son was killed.
Karl was with a group of friends who became involved in an altercation with another group of males.
As he ran from the scene he was stabbed, receiving multiple stab wounds to his head, torso and left thigh.
'Feel the loss'
Ms 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.
"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."
A knife was recovered from the scene and 13 male suspects were arrested in connection with the investigation.
Of those, three were charged and subsequently acquitted at court.
The remaining 10 were released with no further action.
Det Ch Insp Chris Jones 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."
