A central Queensland man who vanished in 2012 may have been murdered over a $30,000 drug debt, a Supreme Court judge has been told.

A central Queensland man who vanished more than two years ago may have been killed over a $30,000 drug debt, a court has heard.

Mackay man Timothy Pullen’s alleged killer was denied bail by a Supreme Court judge in Brisbane on Wednesday over fears he could intimidate witnesses.

Zane Tray Lincoln, 35, who is charged with murdering Mr Pullen, is one of five people who have been arrested over his April 2012 disappearance.

The body of the 34-year-old man has never been found.

Prosecutors outlined the case against Lincoln, a Sunshine Coast resident, including allegations the pair had a previous altercation over a $30,000 drug debt before Mr Pullen’s disappearance.

Crown prosecutor Amanda Robinson said phone records reveal extensive contact between Lincoln and two other suspects during Mr Pullen’s alleged murder.

She said the trio discussed a “$30,000 bounty” on Mr Pullen’s head.

“There’s also that meeting subsequent to the removal of the deceased between two of the co-accused and the applicant where they discuss the clean-up, disposal of evidence, not to speak to police,” she said.

Kiera Jeannette McKay and Nicholas Voorwinden have been charged with Mr Pullen’s manslaughter while Stephen Dale Renwick and Luke Shayne Kister have been charged with being an accessory after the fact.

Ms Robinson referred to a woman who implicated Lincoln in the murder but later retracted her statement.

She added some people had refused to talk to police because they were scared of the father of five, who had a history of interfering with witnesses.

Defence barrister Greg McGuire said the case was “extraordinarily weak” because most of the evidence against his client came from his two co-accused and couldn’t be relied upon.

However, Justice Peter Flanagan refused Lincoln bail, saying there was clearly a case against him and a “real risk” he may interfere with witnesses.

A committal hearing has been set down for November 4 and 5.
