One of Queensland’s most notorious murderers has taken his own life in prison, taking his secrets to the grave a week before the Whiskey Au Go Go firebombing inquest.

The Courier-Mail understands Garry “Shorty” Dubois took his own life in his single-occupant cell at Maryborough Correctional Centre, where he was found unresponsive early on Monday morning.

Dubois was not scheduled to give evidence during the first two weeks of the inquest but was named on the witness list.

He was convicted for the 1974 murders of Brisbane mother Barbara McCulkin and her young children in 1974.

Officers and paramedics tried to revive him but he was declared dead at 5.20am.

Queensland Corrective Services are assisting Queensland police in preparing a report for the coroner.

A spokesman for the Coroners Court of Queensland said the death of Dubois would not cause any interruption to the start of the Whiskey Au Go Go inquest which is due to begin on Monday.

“The impact, if any, that Mr Dubois’ death will have on the inquest will need to be considered,” he said.

“Mr Dubois was not scheduled to give evidence during the two weeks of sittings commencing 14 June 2021.

“Further sittings will be scheduled later in 2021.”

Because Dubois died in custody, his death will be investigated by the Queensland Police Service’s Corrective Services Investigation Unit.

An inquest will also be required to be held in relation to his death.
