Suspect goads Annette's family with lie detector offer

ANNETTE MASON'S relatives have rejected claims from a murderer who goaded the family with a "lie detector" test offer.

Allan David McQueen appeared at Brisbane Coroners Court yesterday, 29 years after Annette was found dead in Toowoomba.

He indicated he would not answer any questions that might incriminate him.

He then turned to Annette's family and supporters in the courtroom, saying he offered to take a "lie detector test" in 2003.

"You just refused that offer. I don't understand why you refused that offer."

"Here I sit here today as the prime suspect. And being given advice…not to answer questions," McQueen added.

"Is that offer still on the table? There was no strings attached."

Adrian Braithwaite, counsel assisting the coroner, objected but McQueen kept on.

"Be quiet. I'm talking," Mr Braithwaite said.

McQueen was excused. Leaving the courtroom, he said a policeman involved in the investigation was "corrupt".

A lawyer for the Mason family said Annette's relatives "never received an offer" from McQueen to take a lie detector test in relation to Annette's murder.

"Mr McQueen's outburst in court today was the first the family has ever heard of this offer," Leanne McDonald of Shine Lawyers said.

In court, McQueen's barrister Damian Walsh said it was understandable his client should refuse to answer questions.

He said some witnesses at the inquest "subjectively" labelled McQueen the prime suspect.

Mr Walsh previously told the inquest there were other suspects, too.

In 1994, former Ipswich man McQueen was sentenced to life in jail for murdering another prisoner.

He was released on parole last month.

Earlier on Thursday, former police officer Paul Ruge said McQueen threatened to kill him and his family at a 1991 inquest.

Mr Ruge said McQueen threatened multiple witnesses at the same inquest.

"When the first witness was called, Allan McQueen shouted out in a very loud voice that if she gave evidence against him, he would kill her," Mr Ruge said.

He said McQueen was eventually removed from court and put in a cell with a TV to watch proceedings.

"He was yelling out from the cells… he would kill them as well."

Meanwhile, limited technology at the time meant many forensic tests were inconclusive, Mr Ruge added.

The inquest was shown photos of the crime scene around Anzac Ave, where Annette was found bashed to death.

But no CCTV cameras were in the area and DNA testing at the time was "in its infancy", Mr Ruge said.

The inquest continues.
