A Brisbane man who raped a woman just days after stuffing a man's body in a wheelie bin in a "depraved" bid to help cover up his death, will spend at least another three years in jail.
Robert Louis Gibson was originally charged with the murder of Kym Mitchell who was beaten to death at a Yeronga unit in November 2018.
Last year, the 41-year-old pleaded guilty to a downgraded charge of being an accessory after the fact to manslaughter, admitting to helping Adam Evans after he unlawfully killed the 61-year-old.
He also pleaded guilty to robbery in company and four counts of rape, in relation to two separate incidents – including a sexual assault of a 21-year-old woman while he was on the run from police after the discovery of Mr Mitchell's body.
'Help me, I'm dying'
During a sentencing hearing in Brisbane on Tuesday, the Supreme Court was told Gibson witnessed Evans fatally assault Mr Mitchell inside the unit and had later admitted to another friend he had given him "a chin-check, but went too far."
The court heard that before Mr Mitchell died, neighbours saw the two men chasing Mr Mitchell in the street, and on the night he was killed, others had heard "struggling" noises coming from the home, and a man calling out "help me, I'm dying".
Gibson helped Evans evade police detection by disposing of the 61-year-old's decomposing body, before dumping his mobility scooter in a river and cleaning the crime scene, the court heard.
The court also heard that three days later he forced himself on a random 21-year-old woman and raped her multiple times while she was walking home from a Runcorn pub.
He told the woman he was wanted by police for killing someone and had threatened: "If you don't do it — you'll end up murdered like the man".
'Cast aside like rubbish'
Gibson was sentenced to eight years in jail for the rapes and handed concurrent and cumulative lesser sentences for the remaining offences.
When handing down her ruling, Justice Sue Brown described Gibson's offending against Mr Mitchell as "depraved", telling the court he showed "little regard" for him by handling his corpse in "such an undignified way".
Justice Brown said the offending against the woman had been "degrading and humiliating" and that he had used her as a "convenient vehicle for [his] sexual gratification".
She told Gibson, who was a long-term drug user, he could not "simply blame" his addiction for his offending.
"You made choices, and they were choices with devastating effects," she said.
Gibson, who has been in custody since his arrest in 2018, will be eligible for parole in September 2025.
Evans has pleaded guilty to manslaughter and is awaiting a sentence hearing.
