The former police chief who led the Peter Falconio murder investigation believes his body may never be found, despite new laws encouraging the killer to say where it is.

On the 15th anniversary of the Huddersfield backpacker’s death in Australia, Colleen Gwynne, who was promoted to be in charge of the Alice Springs region during the investigation, said she thinks his body may never be recovered.

And she told ABC she knew drug runner Bradley Murdoch was the killer from the outset.

“There was never any doubt for me that Bradley Murdoch was guilty of this crime,” she said. “The challenge was to make sure we got a conviction.”

New legislation prevents murderers from receiving parole until they reveal a body’s location, but Ms Gwynne said: “Do I think he’ll disclose – no I don’t. He maintains he is innocent to this day and the arrogance of the man astounds me.”

Murdoch was convicted in 2005 of murdering 28-year-old Peter and assaulting his girlfriend Joanne Lees, formerly of Almondbury, at gunpoint on a remote stretch of highway near Barrow Creek, about 200 miles north of Alice Springs, on July 14, 2001.

    Around 7.30pm a vehicle draws level with the camper van, indicating a problem with the exhaust of the couple’s van. Joanne is nervous about stopping in the outback but Peter pulls over, gets out and speaks to the other driver. He asks Joanne to rev the engine, then returns to the back of the van.

    Joanne hears a bang and the man appears at the driver’s window of the van.

    He threatens her with a gun to her head, ties her hands behind her back and forces her into the back of his vehicle.
