AN 11-year-old unsolved murder is to be reviewed by detectives. No-one has ever been caught for the murder of 16-year-old Claire Tiltman in an alleyway in Greenhithe, near Dartford, in 1993.

Now police are re-investigating the case by talking to witnesses and retracing the schoolgirl's last steps using the latest computer technology.

Claire's death remains one of the biggest unsolved murder cases in Kent. She was the victim of an apparently motiveless killing less than two miles from her house.

Claire was attacked in the early evening of January 18, 1993 after she appeared to take a short cut on her way to visit a friend.

The teenager, who had turned 16 just days before, received multiple stab wounds and staggered into the arms of a passer-by. The Dartford Grammar School for Girls pupil died at the side of a busy road.

Crime case reviewer David King and Det Insp Tony Hubbard have been re-examining the investigation into Claire's death since January 2003.

They are still waiting on the result of DNA tests carried out on items taken from the murder scene, having already looked through more than 16,000 documents gathered during the initial inquiry.

Detectives are hoping to begin interviewing people who gave statements to the original 120-strong police team by the end of the summer.

A spokesman for Kent police said: "Reviews in long-term unsolved murder cases are quite normal practice within Kent police."
