Claire Tiltman murder: Schoolgirl's killer loses appeal bid
A man jailed for life for murdering schoolgirl Claire Tiltman in 1993 has failed in an attempt to challenge his conviction.
Judges at the Court of Appeal on Friday dismissed an application by Colin Ash-Smith (47) for permission to appeal.
Lord Justice Davis, sitting with two other leading judges in London, announced that his case was "unarguable".
In December Ash-Smith was ordered to serve a minimum of 21 years behind bars for the attack.
He stabbed Claire (16) to death in an alleyway near her home in Greenhithe, Kent.
The judges rejected submissions that the trial judge wrongly allowed "gravely prejudicial" material to go before the jury.
