THREE Rockhampton prisoners who bashed and murdered a fellow inmate in 1999 have failed in their attempt to have their convictions overturned.
Wayne Thomas Robertson, Mark Dempsey Knight and Wesley Robert Williams were convicted in 2012 of murdering Robert James Buckley in the Etna Creek prison.
The Queensland Supreme Court on Friday dismissed their appeal against the murder conviction.
The three killed Mr Buckley, who was in prison after stealing gold from his father-in-law, to find where he stashed more gold.
They bashed him in a shower block and hung him from a window with a towel - and then claimed he had committed suicide.
In appealing their convictions the trio said suicide remained a reasonable explanation for Mr Buckley's death and claimed evidence Mr Buckley wrote or said before his death should not have been allowed in court.
They said there was a lack of evidence against them with none of their blood, DNA or fingerprints being found in the shower block or on Mr Buckley, or any of his blood or DNA on them.
However, Mr Buckley's DNA, or grease which was on his hands, were not found on the towel which he was hung with.
Justice Catherine Holmes dismissed their men's claims stating the jury had been entitled to believe beyond reasonable doubt they were guilty.
"There was a body of evidence capable of supporting the conclusions that the three appellants were involved in the assault of Mr Buckley and that he was hanged very shortly after it," she said.
The Court of Appeal dismissed an appeal last year from the trio when they suggested jury bias after a juror talked to his barber.
Knight had previously been convicted of murdering a fellow inmate, while Williams had been jailed for manslaughter when he hit a man in the head with a metal pole when trying to steal $80.
