The man jailed for killing British backpacker Peter Falconio in the Australian outback has launched an appeal against his conviction.
Murdoch consistently denied responsibility for the killing
Bradley Murdoch, 47, was sentenced to at least 28 years in jail after being convicted of murder in December.
He was also found guilty of abducting Mr Falconio's girlfriend, Joanne Lees, of Brighton, in the July 2001 attack.
Murdoch's lawyer, Ian Reed, has lodged appeal documents with the Northern Territory Supreme Court in Darwin.
He is seeking leave to appeal in the Court of Criminal Appeal.
Outside court, Mr Read refused to outline the grounds for the appeal but said: "It's been lodged."
After the trial, Murdoch's barrister, Grant Algie, indicated his intention to appeal within minutes of him being found guilty. Mr Falconio, 28, of Hepworth, Huddersfield, was killed on an outback road north of Alice Springs.
Body not recovered
Murdoch shot him dead before threatening Ms Lees with a gun and tying her up.
She managed to escape and hide in the bush for more than five hours before being rescued.
Mr Falconio was never seen again and no body has been found.
Mr Murdoch has always denied he was the killer and no motive for the attack has been established.
