Claire Tiltman murder: Friends still hope for justice
Friends of a 16-year-old girl murdered 21 years ago say they still hope her killer will be brought to justice.
Claire Tiltman was stabbed to death in an alleyway close to her home in Greenhithe in 1993, but her attacker has never been found.
A charity concert is being held by the Justice for Claire campaign at Dartford FC's ground later to mark the anniversary of her death.
Kent Police said they were still actively investigating the case.
The campaign began in 2012 following the death of Claire's father, Cliff. Her mother Linda died in 2008.
Joanne Roberts, who knew Claire from their playgroup days and at Dartford Grammar School, said organising the concert had brought back the events of 18 January 1993.'Remember nightmares'
"I think we shut a lot of it out but I can remember deep disbelief inside," she said.
"You can't process it in your mind at all - I just remember the nightmares.
"It brought everybody closer together and we all became a big group of friends all supporting each other but I feel it took away our innocence and our teenage years.
"You felt more wary of going out.
"We would never have been like that before - it changed everything for a long, long time.
"It is tinged with sadness that Lin and Cliff wouldn't be here to see it but I would love to see justice done for her.
"No one should feel it's too late to come forward with that little bit of information that will solve the case for us."
Det Chief Insp Rob Vinson said some of the officers involved in the inquiry have been investigating the case for many years.
"It is one of those that anyone who has any involvement is absolutely committed to try and bring some resolution to it," he said.
