WATCH: Australian police ask killer of Yorkshire backpacker to reveal location of body before he dies

Bradley John Murdoch was convicted in 2005 of murdering Mr Falconio, 28, and assaulting his girlfriend Joanne Lees at gunpoint on a remote stretch of road near Barrow Creek in Australia’s Northern Territory on July 14 2001.

Mr Falconio and Ms Lees, both from Yorkshire, were travelling across the country in a camper van when they were ambushed by Murdoch on the Stuart Highway, an isolated road that runs through the centre of Australia.

Murdoch was convicted and sentenced to life imprisonment without parole for at least 28 years.

Bradley Murdoch was convicted in 2005 but died in prison in 2025.

Peter Falconio and Ms Lees had been driving near the tiny settlement of Barrow Creek, around 188 miles north of Alice Springs, when Murdoch pulled up beside them claiming to have seen sparks coming from their van.

He shot Mr Falconio in the head as he inspected the vehicle, before forcing Ms Lees into his vehicle and binding her wrists with cable ties.

She managed to escape, hiding in the Outback for hours before flagging down a passing truck.

During the trial, prosecutors argued that Murdoch was likely to have disposed of the backpacker’s body somewhere in the vast, remote expanse of desert between Alice Springs and Broome, covering more than 1,200 miles.

Footage released by Northern Territory Police Force to mark 25 years since the murder shows the officer speaking to Murdoch and asking him to reveal the location of the body before his death.

However, Murdoch refuses.

A police officer can be heard saying to Murdoch: "I need you to have a think about if Peter Falconio was your son."

In the footage, he responds: “I don’t know anything about it.

“I know nothing, I have said this for 22 years.

“You keep asking these questions.

“I am not thinking about it, I have thought about it for 22 years.

"I don’t have the information.

"I've said the same story over and over and over, and now you're here at the last minute because I'm dying.”

An initial reward of $250,000 was increased last year to $500,000 in the hope that someone with information that leads directly to the discovery of Peter Falconio's remains comes forward.

NT Police: “Our thoughts remained with the Falconio family and Joanne Lees whose loss and uncertainty continue to be felt 25 years on.

"25 years is a significant milestone, and the Northern Territory Police Force remains committed to bringing this investigation to its fullest conclusion and will continue to pursue every avenue available.

"There may still be someone who knows something, whether that be information they have never previously shared with police or something Murdoch said to them.

"We continue to urge anyone with information relating to the location of Peter Falconio's remains to come forward.

"No piece of information is too small; what may seem insignificant could prove critical in helping investigators finally resolve this case."
