A KILLER and rapist, who has spent more than three decades in jail, could be under supervision for another 20 years if he is released.
Mark Richard Lawrence has been in prison for more than 30 years - after killing a fellow Wolston Park Hospital patient in 1983 and raping a fellow inmate in 1999.
The Brisbane Supreme Court on Monday reviewed his indefinite detention as a dangerous sexual offender.
Lawrence's clinical psychologist Lars Marsden said Lawrence had admitted to having "deviant sexual fantasies" involving rape while watching police television shows.
Mr Marsden said he believed Lawrence had better coping mechanisms than he had when he offended in the past - but said the stresses of modern life and media coverage about his release may increase his risk of re-offending.
Similarly psychologist Dr Joan Lawrence said on one occasion Lawrence had been "outraged" at coverage of his case in the media and had attempted to justify his anger, claiming he was worried for the families of the victims.
Dr Lawrence said she did not believe he was actually worried for them. She said Lawrence's risk of re-offending would be "lifelong".
Despite this Dr Lawrence said she believed the risks of Lawrence re-offending could be mitigated through a long-term supervision period.
Justice Roslyn Atkinson said Lawrence's case was in the "balance" and if he was to be released he could be under supervision for 15-20 years.
Lawrence was released from his indefinite detention in 2014 before the government appealed against his release.
The Court of Appeal found the decision to release him then was an error.
Judge Atkinson's decision will be released at a future date.
