Zlatko Sikorsky, 37, (pictured) was allegedly bashed to death by a fellow inmate at Wolston Correctional Centre in November
The maximum security prisoner who allegedly bashed a teenage girl’s suspected killer to death in jail has been revealed for the first time.
Isaac James Martin, 26, was charged with one count of unlawful striking over the death of fellow inmate Zlatko Sikorsky during an alleged altercation at Queensland‘s Wolston Correctional Centre in November.
At the time of his death, Sikorsky, 37, was awaiting trial for the alleged torture and murder of his 16-year-old girlfriend Larissa Beilby south of Brisbane in June 2018.
Martin didn’t appear via videolink when his case was briefly heard in Brisbane Magistrates Court on Tuesday.
His lawyer Jon Ide asked the court for a brief of evidence, which Magistrate Michael Quinn ordered to be available by February 23, the Sunshine Coast Daily reported.

Martin’s case has been adjourned until March 15.
Martin struck Sikorsky in the head an alleged altercation at Wolston Correctional Centre on November 10, according to court documents.
Sikorsky was rushed to Brisbane’s Princess Alexandra Hospital suffering critical head injuries, where he spent 10 days on life support before he died on November 20.
‘Our condolences go out to the man’s family and friends,’ a Queensland Corrective Service statement read.
Sikorsky had been awaiting trial in Brisbane Supreme Court accused of murdering and torturing 16-year-old Larissa almost 18 months prior.
Larissa was last seen in the north Brisbane suburb of Sandgate on June 15 2018 and was reported missing 12 days later 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.

Sikorsky dumped the ute at a gated community in Stapylton, where Larissa’s body was found shoved into a barrel on the tray.
The teen was also gagged, causing cuts to the inside of her mouth and raising the possibility she died by asphyxiation.
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.
‘With a broken heart shattered into more than a million pieces our family is utterly destroyed to inform you all that Larissa has been taken from us,’ Larissa’s older sister Deanna posted on Facebook at the time.
‘Our beautiful girl has been reunited with our beloved wife and mother.’
‘Fly high our darling angel, until we see you again Rissy.’
The girls’ mother Karen died 14 years earlier.

During his trial, the doctor who examined Larissa’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.
While the June 23 anniversary of her death is difficult each year for Larissa’s grieving family, her sister said June 30 will always be etched into her memory.
‘The confirmation of identity day,’ Deanna explained on the two year anniversary of her younger sister’s death last June.
‘Nothing will ever amount to the level of pain this day brought… It will forever be more difficult than June 23, because we had no idea… at that point.
‘Our world literally crashed.’
‘My world has been indescribably altered and I’m rebuilding my entire heart and life.’
