A man who committed "every woman's worst nightmare" by raping and murdering a young woman in her home "remains a danger to the community" 34 years later, an Adelaide court has heard.
Jonathan Peter Bakewell was on parole for a violent robbery in South Australia when, in 1988, he travelled to the Northern Territory where he raped and murdered Anne-Marie Culleton.
Ms Culleton was just 20 years old.
She had obtained a job, a car and had moved into her first flat in suburban Darwin only three weeks earlier.
Bakewell broke in through the locked backdoor and raped and murdered her in her bed before putting her body in a "scolding hot shower".
He was sentenced to life in prison but served the last decade of his sentence in South Australia to be closer to his dying father.
Since his release on parole in 2016, Bakewell has breached his parole six times by testing positive to cannabis.
He was taken back into custody four months ago but has now applied to the Supreme Court to have another non-parole period set.
Ms Culleton's younger sister, Eileen, told the court in a victim impact statement Bakewell had tested positive numerous times to using the same drug he had taken on the night he cut short her "beautiful" sister's life.
She also asked the court "for him to serve out the rest of his life sentence behind bars".
"Bakewell broke down Anne-Marie's locked back door in the middle of the night to rape and murder her in her bed is every woman's worst nightmare; it became my living nightmare," she said.
Ms Culleton told the court she feared for her own safety and the general safety of women in the community if he was to be released.
"I grapple with intense fear that he will commit another horrific crime in the community.
"I am concerned these multiple breaches demonstrate a refusal to follow the rules of parole and society in general."
Breaches 'relate only' to cannabis, lawyer says
But Bakewell's lawyer, Greg Mead SC, told the court his client had taken cannabis while on parole to treat pain for throat cancer.
"The substantial operative substance [in Ms Culleton's rape and murder] was alcohol, but he had taken some cannabis … about 24 hours prior to the offending," he told the court.
"Mr Bakewell's now before the court because of a number of breaches of parole which relate only to the use of cannabis.
"There's no further offending, there's no use of alcohol, there's years of good institutional reports, there are positive efforts to rehabilitate and reintegrate into the community."
Prosecutor Kirby Draper told the court Bakewell had been "deceptive" about his drug uses and parole breaches.
But she told the court she did not oppose a non-parole period being set.
Chief Justice Chris Kourakis has reserved his decision.
