A convicted killer has been found guilty of raping a woman in Bristol while on parole.

Mark Shirley subjected his victim to a "petrifying" rape ordeal in a bid to re-enact elements of the murder he committed 22 years ago, Bristol Crown Court previously heard.

The 39-year-old imprisoned the woman in her own home, raping and sexually assaulting her at knifepoint for three and a half hours, the court heard.

Shirley, who was living in Richmond Road, Easton, was found guilty of one count of false imprisonment, one count of rape, three counts of assault by penetration and one count of committing false imprisonment with the intention of committing a sexual offence.

The jury was previously told Shirley was convicted of murdering 67-year-old Mary Wainwright when he was just 16 years old, in Cardiff in 1987.

He was handed a life sentence but was released on parole after 16 years in 2003. He was later recalled to prison for excessive drinking but released again in August 2008.

It was after his second release from prison, on March 20 this year, that Shirley committed the attack.

During his trial Shirley told the court no such attack took place, though he admitted being with the alleged victim at the time the offence is said to have taken place.

The Honourable Mr Justice Royce remanded Shirley in custody, pending a report, until sentencing on December 15.

Rosaleen Collins, prosecuting, told the court: "The idea any of us or our loved ones would be the subject of a sexual attack in the street would be probably one of our collective greatest fears.

"To be the subject of a serious sexual assault in the privacy of your own home, within the comfort, security and hub of your family life is probably one of anyone’s greatest nightmares.

"March 20, 2009, to (the woman), at the hands of this defendant, was her greatest nightmare. He targeted her in her own home and he abused her in quite the most repulsive of ways."
