A father has made an impassioned appeal for the public's help in finding his daughter's killer on the 19th anniversary of her death.
Cliff Tiltman, 62, said he has never given up hope that one day the person responsible for murdering his daughter, Claire Tiltman, would be caught.
Only child Claire was aged 16 when she was stabbed to death in an alleyway off the A226 London Road in Greenhithe, Kent, on January 18, 1993.
The Dartford Grammar School pupil was knifed more than 40 times in a frenzied attack as she took a short cut to visit a friend, four days after her 16th birthday.
Speaking from his bed in a nursing home, retired plumber Mr Tiltman said: "It would mean everything to me to find out, after all these years, who did this to Claire. It has been a long time, but I've never given up hope and never will.
"I can't begin to put into words how this has affected our family. Claire has gone. Her mum has gone. There is now only me.
"I try to stay strong but will still hide and cry my eyes out for an hour. She would have been 35 now. She was a good kid. I miss her to bits."
A major murder inquiry was launched but no one has ever been charged with Claire's killing. Kent Police said the case remains open and has been subject to a number of reviews by cold case detectives.
In 2010, Mr Tiltman had hoped for a breakthrough when a handwritten cardboard sign left among flowers above a plaque where Claire was stabbed claimed to name the killer. The mysterious sign also claimed to name the type of car he drove and the company he worked for.
A man was traced by police and co-operated with officers but he was later ruled out of inquiries, dashing any hope Mr Tiltman had that closure could be brought.
