BRADLEY John Murdoch was the man in truck stop security footage filmed shortly after backpacker Peter Falconio disappeared, a court heard today.

Forensic anatomist Meiya Sutisno told the Northern Territory Supreme Court in Australia that Murdoch - the man accused of murdering the 28-year-old backpacker from Huddersfield - shared a number of distinctive face and body features with the man in the video.

She added: "The multiple number of features matched indicated the level of identification to be the same person."

The man was filmed at the Alice Springs truck stop early on July 15, 2001.

This was just hours after Mr Falconio disappeared from beside the Stuart Highway, near Barrow Creek, about 180 miles (300 kilometres) from Alice Springs.

Dr Sutisno, an expert in body and facial mapping, compared distinctive features, including sloping shoulders, a long torso, jaw, chin and walking manner, between the man in the video and Murdoch.

She said: "I found there were multiple features that matched."

However, Chief Justice Brian Martin told the jury the video alone could not prove Murdoch killed Mr Falconio.

"The fact that the accused was in Alice Springs, if that's your finding eventually, in the early hours of July 15, of course by itself, and I stress by itself, cannot prove that the accused was the offender," he said.

"What we're talking about here are a series of circumstances which eventually you'll be asked to put together and make findings about.

"If you find it to be a fact eventually, that the accused was in Alice Springs at this time, it will become one of the circumstances."

Murdoch, 47, of Broome, Western Australia, has denied murdering Mr Falconio, of Hepworth, who vanished after an alleged ambush on the Outback highway.

No body has ever been found.

Murdoch has also denied abducting and assaulting Mr Falconio's girlfriend, Joanne Lees, of Almondbury.

Dr Sutisno said she had helped police in previous cases with body and facial mapping.

She is now helping the Indonesia authorities to identify the remains of wanted bomb expert Azahari Husin.

They contacted her late last week to help identify the remains of Azahari, a key member of the Jemaah Islamiah terrorist network.

He was killed when Indonesian forces stormed a hideout in East Java.

Meanwhile, the Australian court also heard from a policeman involved in searching for Mr Falconio's body - and a possible murder weapon - in the months after he disappeared.

Superintendent Bruce Grant said police combed a 320,000 square metre area with metal detectors, trying to find a murder weapon at the Barrow Creek crime scene.

He said police had information that a watch, car keys, a religious medallion, a murder weapon and bullet were missing, or had not yet been recovered.

But nothing of significance was found, he said.

The case continues.
