The only person charged over an outback triple homicide has admitted he lied to police, as a court heard evidence that his father claimed “the little bastard done it”.
Bruce Preston, 70, was charged with the 1978 shooting of Timothy Thomson, 31, his girlfriend, Karen Edwards, 23, and their friend, Gordon Twaddle, 21, who were found dead at a bush track at Spear Creek outside Mount Isa in Queensland’s north-west.
For the first time in years, Preston has spoken of the police investigation, telling the inquest he spent 11 months in custody after he was charged, and he had done nothing but think of the case.

Thomson, Edwards and Twaddle had been on a motorbike trip from Alice Springs, with plans to head to Cairns then on to Melbourne for Christmas.
But the group never made it. Their bodies were found with gunshot wounds to the head, and forensics officers determined they had been shot with a .22 calibre rifle.
The inquest earlier heard evidence that the trio were seen with a red BMW motorbike with a sidecar attached so Thomson’s dog could ride in it.
This bike became a major focus of the police investigation.
Preston was found in possession of the red motorcycle and pleaded guilty to stealing it. He was fined $300, the inquest heard earlier.
Detectives were believed to have had a breakthrough in the case in 2019, charging Preston, a former prison guard at NSW’s Goulburn Supermax jail, with the murders. However, all charges were dropped in July 2023. He had denied the charges.
Sitting in a wheelchair on Tuesday, the 70-year-old was asked repeatedly during the inquest about his police statements in relation to how he claimed to have found the BMW motorbike on the outskirts of Mount Isa then later said he found it in the town’s centre.
He was asked if he initially told lies about where he found the motorcycle. Preston answered yes.

When asked why, he said: “I don’t know, it’s 47 years ago. I was a young fellow, I panicked.”
Coroner David O’Connell asked him if he moved the location in his police statement to put the bike further away from Moondarra Caravan Park, where the trio had been staying and were last seen alive on October 5. Preston answered no.
O’Connell repeatedly pointed out that although Preston had claimed privilege from indemnity over his answers, he could still face a risk of perjury.
Preston, who travelled from Alice Springs to Mount Isa earlier in the month in 1978, reiterated that he had struggled to recall dates and places. At one point he told the inquest he had spent a further two days in Alice Springs, despite telling police he left earlier, and his family confirming he arrived in Mount Isa about October 4 or 5. The three were found dead on October 24.

At times throughout the hearing, Preston appeared to be rattled and flustered while giving his evidence.
His older brother, Ian, told the inquest that at the time, their father, Arthur, had been concerned that the red motorbike in Preston’s possession “was involved somehow”.
Ian told the court he also went to police about his brother. He said: “The thoughts I had were that I was afraid if anybody had been involved in these sorts of events.” When asked who he was referring to, he answered his brother.
The 76-year-old recalled how he and his brothers used to go pig shooting with their father when they were boys.

Their father, according to Ian, was an avid hunter and shooter. The family also used to shoot kangaroos, sending their skins back to Brisbane to be tanned and sold, the inquest heard.
When Ian turned 15, he left the family and joined the navy. He did not agree with many of his father’s opinions and wanted to get away, he told the court.
After Ian married in 1973 – the year before the Spear Creek deaths – he returned to Mount Isa with his wife for a trip. During that time, he asked his father about his old .22 pump-action firearm, which he wanted to have back.
He was told that Arthur’s wife, Yvonne, now had the gun and was using it to shoot, Ian told the court.
He said the following year, his brother called him from Adelaide and told him he had bought a BMW motorcycle and had it transported to Mount Isa.
Ian said he believed Preston was a member of the Black Uhlans outlaw motorcycle gang and recalled seeing his nickname, “Pedro”, on his jacket.
The court heard that at one time, Arthur Preston told a friend while discussing Bruce Preston and the murders: “The little bastard done it. But he’s a tough little bastard, and they can’t break him.”
It was suggested to Ian Preston that he was harbouring a family secret that was no longer private, given that it was in the public arena. Ian said he was not harbouring anything, and was not aware of his father’s conversation.
Merrill Anderson, who lived across the road from the Prestons in Mount Isa, earlier told the inquest she believed Arthur Preston was “running interference” at the time by suggesting to help police search the Moondarra Dam looking for the bike.
Arthur was a ranger who knew the lake and area well.
Anderson told the court she quite liked Bruce, who would willingly demonstrate how to ride motorbikes to the kids in the community. She described him as patient and tolerant, and always a gentleman, who never used bad language.
But at times, he would be moody, she said.
She recalled how she had seen Bruce riding around town with a motorbike, which she believed to be a reddish BMW, and he did not try to hide it in any way. Anderson said Bruce even took her sons for a ride on it to the corner and back.
“He was not in any way trying to be secretive about the bike,” she said.
But around the time police began looking for the motorbike in connection to the deaths, Bruce stopped riding it, Anderson said.
She recalled how his stepmother, Yvonne, explained to her that the bike was in the shed and needed parts. When Anderson saw the bike one day with marks on the side, she said: “You know what, I think this is the bike the police are looking for.”
Later, she and others went to the Spear Creek site, where they found bullet shells and a bullet hole in a tree. Anderson said she believed Bruce also visited the site with a group of people, but she said it was difficult to say with certainty.
The inquest continues.
