Colin Ash-Smith was found guilty today of the murder of schoolgirl Claire Tiltman in Greenhithe, in a "frenzied and remorseless" attack.

Here is how events unfolded after the murder more than 20 years ago.

January 18 1993 - Claire is stabbed to death in an alleyway off London Road, Greenhithe, as she walks to a friend's house, four days after her 16th birthday.

February 1994 - Milkman Colin Ash-Smith attends Claire's funeral with his father Aubrey and mother Diane, a local Labour councillor at the time. Ash-Smith wore the beige jacket he is said to have had on when he stabbed Claire.

October 1995 - Ash-Smith stabs Charlotte Barnard, 21, at least 14 times in a frenzied attack yards from where he killed Claire. He is arrested by police, and admits the attack along with the attempted rape and attempted murder of a young mother at a quarry in 1988. He is also questioned as a suspect in Claire's murder, but not charged.

December 1996 - Ash-Smith is handed three life sentences for the other two attacks.

March 2008 - Claire's mother Linda dies after fighting for years to bring her daughter's killer to justice.

September 14 2012 - Claire's father Cliff dies never having seen his daughter's killer come to court. Earlier in the year he issued a murder appeal from his nursing home bed. Claire's school friends vow to take up the fight to find her attacker.

September 2013 - Police search Ash-Smith's family home in Kent as part of a cold-case review into Claire's killing.
