[2] Claire Tiltman, a Year 11 pupil at Dartford Grammar School for Girls, took a short cut down an alleyway on her way to meet a friend near her home in Greenhithe.
He was charged on the day he was due to be considered for release by the parole board, having served 18 years of a life sentence for the two previous attacks on women.
In a victim impact statement, her uncle said: "The fact they allowed her out on the night of her death caused them a massive amount of pain.”[10] Ash-Smith was already a known violent offender, and was first identified as a suspect in the murder of Claire Tiltman almost 20 years before he was finally convicted.
[14] He denied attacking Claire, and had attended his victim's funeral a month after the killing with his Labour councillor parents, wearing the same beige jacket he had worn on the night of the murder.
[15] He was aged 24 at the time of Tiltman's murder, and working locally as a milkman, and still lived with his parents at their home in Swanscombe.
According to the CPS, Ash-Smith developed a pattern after the murder and set up false alibis on four occasions as well as increasing the ferocity and severity in his attacks.
[2] Colin was denied a Special Purpose Licence to attend his father's funeral after news that he could potentially be allowed a temporary release to do so was met with public outcry on social media.
[15] In November 2015, Ash-Smith launched an appeal against his conviction on the grounds that Mr Justice Sweeney had wrongly allowed "gravely prejudicial" material to go before the jury.
[18][19] Ash-Smith's conviction was among the cases featured in the BBC Four three-part documentary The Prosecutors, which showcases the CPS's work and the legal procedures behind a prosecution.
