A man accused of murdering his girlfriend and dumping her body in a barrel has died after being brutally bashed by a fellow prison inmate.
Zlatko Sikorsky was charged with murdering and torturing Larissa Beilby, 16, at Buccan, south of Brisbane, in June 2018.
The 37-year-old was bashed in an early-morning ambush by another prisoner at Brisbane’s Wolston Correctional Centre before he was rushed to Princess Alexandra Hospital on November 10.
He suffered critical head injuries and was on life support before being pronounced dead on Friday morning.
The Queensland Corrective Service confirmed the death and said investigations were continuing into the prison brawl.
‘Our condolences go out to the man’s family and friends,’ they said in a statement.
‘Support is being offered to the responding officers and their colleagues at Wolston Correctional Centre.’

On November 11 the QCS confirmed the injuries were a result of an altercation with another prisoner.
Sikorsky is accused of murdering and torturing 16-year-old Larissa on June 23, 2019 and had been awaiting trial in the Brisbane Supreme Court.
Ms Beilby was last seen in the north Brisbane suburb of Sandgate on June 15, and was reported missing on June 27 by her father Peter.
Police were at a house in Buccan making inquiries into her disappearance when Sikorsky, who was at the property, got into a black ute and fled.
While on the run, Sikorsky threatened a woman with a shotgun and offered her $2000 to be let inside her home.
The woman then noticed a ‘dead arm’ hanging out of the ute.
‘All I’ve seen is an arm flapping out… There was just the one barrel, it wasn’t massive either, it was only small. I just saw an arm, a dead arm,’ the woman told the media in 2018.
Sikorsky dumped the ute at a gated community in Stapylton, where the teenager’s body was found shoved into a barrel on the tray on June 28, 2018.

Armed with weapons, Sikorksy eventually holed himself up at the Sunshine Coast apartment block and began making demands of police.
After a 24-hour siege, he surrendered and was charged with murder, torture and deprivation of liberty and interfering with a corpse.
During his trial, the doctor who examined Ms Beilby’s body said her injuries were unlike anything she had ever come across.
‘I have done over 7,000 autopsies and I have never seen anything like this,’ Dr Dianne Little told Brisbane Supreme Court in 2018.
The teen was also gagged, causing cuts to the inside of her mouth and raising the possibility she died by asphyxiation.

Sikorsky was accused of murdering and torturing the teen, with one witness saying he said he wanted to ‘knock’ her because she knew too much.
His former housemate Scott George Thompson had previously told the court about the final hours leading up to Ms Beilby’s death.
He said Sikorsky told him Ms Beilby was ‘not in a good way’ after hearing a scream in the backyard of their Buccan home.
‘We had a conversation with him saying something about ”that chick, she was driving him insane”,’ Mr Thompson said.
He told the court he believed Sikorsky had punched the girl in the face.
‘I said ”just drop her to hospital” (but) he was saying he wanted to knock her,’ Mr Thompson added.
‘He said ”no, she knows too much”.’
Mr Thompson said he didn’t go to investigate because he was afraid of Sikorsky, who he said was high on drugs and carrying a gun.
