An anonymous letter claims the remains of British backpacker Peter Falconio, who was murdered on a remote outback road in one of the Australia's most notorious crimes, were buried in remote Western Australia.
The Northern Territory News says it was sent the letter from an Australian ex- pat now living in London, and police are looking into it.
The letter details how Mr Falconio's body was cut up, put into plastic bags and taken to Adelaide then to Perth by train before the remains were buried around Geraldton in WA.
The letter writer says Bradley Murdoch, who was convicted of Mr Falconio's murder, called an associate and told him to meet him the the outback because he needed help to dispose of a body.
"When they met, Murdoch told (the associate) that he had murdered a guy in self- defence. At the time, (the associate) had no idea who the victim was," the letter to the NT News said.
"Murdoch had cut the body up and put it in two large ... bags that were watertight and smell proof."
The letter said Murdoch ordered the associate to drive to Adelaide and fly to Perth, but he decided to take the train instead thinking the bags would attract less attention,
"(The associate) told me he went way past Geraldton and buried both the bags unopened in a nice spot and even made up a cross," the letter said.
"Later he realised who he had buried and was in a bad way about it."
In a statement to the NT News, a police spokesman said police were reviewing the letter to determine whether it should be investigated further.
Murdoch was convicted in 2005 of murdering Mr Falconio, 28, and assaulting his girlfriend Joanne Lees on a remote stretch of highway near Barrow Creek, north of Alice Springs, on July 14, 2001.
Mr Falconio and Ms Lees were driving along the Stuart Highway when Murdoch drove up behind them and indicated they should pull over, saying their van might have an engine problem.
Mr Falconio went behind the car with him to investigate, and Ms Lees heard a gunshot, before Murdoch cable-tied her and covered her head.
She escaped and hid in bushland for five hours while Murdoch hunted her with his dog, before she managed to flag down a truck driver.
Murdoch is believed to have hidden Mr Falconio's body, which has never been found despite extensive searches.
