Zlatko Sikorsky, 37, who's accused of killing Larissa Beilby, 16, has died after a prison fight.

A man accused of bashing Queensland teen Larissa Beilby to death has died after after an assault by another prisoner.

Zlatko Sikorsky, 37, was rushed to Princess Alexandra Hospital with critical head injuries after a fight with another inmate at Woolston Correctional Centre on November 10.

Queensland Corrective Services confirmed Sikorsky died in hospital on Friday morning and an investigation is underway.

"The injuries are a result of an altercation with another prisoner," a QCS statement said on Wednesday, November 11.

Sikorsky is accused of murdering and torturing 16-year-old Larissa Beilby on June 23, 2019 and had been awaiting trial in the Brisbane Supreme Court.

Her battered body was found inside a barrel on the back of a ute abandoned at a residential complex on the Gold Coast on June 28 last year.

Chantelle Maker later told a committal hearing at Beenleigh Magistrates Court she gave the teenager methamphetamine in the lead-up to her death to protect her from Sikorsky after he beat her up.

"She needed to stay awake so she could still be alive. She was purple from head to toe," Ms Maker told the court.

"That purple that I was so frightened for her that when he went for a shower, I snuck out and got her phone so she could put it all over social media."

"Because she wouldn't go to the police station with me."

Ms Maker said she was "petrified" of Sikorsky, who she alleged had abducted her on more than one occasion and threatened to kill her.

She also recalled the day when she helped Sikorsky allegedly steal the black ute that Larissa's body would later be found in.
