Mark Shirley was warned he faces a possible life sentence
A convicted murderer has been found guilty of raping a woman in a re-enactment of his previous crime while out of prison on licence.
Mark Shirley, 39, held the woman in her Bristol home at knifepoint before raping and sexually assaulting her.
Bristol Crown Court heard during the attack he tried to recreate the murder he had committed 22 years before.
He was sentenced to life in 1987, aged just 16, for murdering a Cardiff woman, but was later released on licence.
Judge John Royce deferred sentencing to 15 December, but warned Shirley he faced a possible life sentence.
Shirley was jailed for life for the murder in Cardiff of 67-year-old Mary Wainwright. She had been beaten and stabbed.
Mrs Wainwright's flat had been ransacked and there were several ritualistic features to the killing.
Giving evidence to the jury, his victim fought back tears as she re-lived the attack.
She said: "He said he once knew a lady, a sweet lady and her name was Mary. He kept saying I was a trustable and sweet lady like her.
"He said had been watching her for a couple of weeks when he broke into her house.
"He said when he broke into her flat he laid her on the floor. He said he held her on the floor then stabbed her in her side."
She added: "He treated me like Mary. I firmly believe he was talking to Mary."
The Parole Board, which made the decision to release Shirley from prison, is to carry out a review of the case.
Shirley was given a 12-year term, and was refused parole twice before being released in 2003.
He was recalled to prison twice, and freed again in August 2008.
Seven months later, Shirley carried out the rape in north Bristol, attacking his victim with a flick-knife.
At the time of the rape, Shirley was under supervision in the community. He was required to report to a probation officer once a month.
A Parole Board spokesman said Shirley's case has been referred to the Parole Board Review Committee.
He added: "With all life sentence prisoners the statutory test that the board must apply when considering whether they are suitable for release is whether it is necessary for the protection of the public that the prisoner be detained.
"There must be more than minimal risk to life and limb to justify the continued detention of the prisoner."
