A Scottish man convicted of the murder of his girlfriend, Jodi Jones, in 2003 has been allowed to release a video of himself passing a lie detector test in an attempt to prove his innocence.
Luke Mitchell, 24, and Jones were both 14 when she was brutally killed in Easthouses, Scotland.
Mitchell was convicted in 2005 and is serving a minimum of 20 years. He has always protested his innocence and took the polygraph test last April at Shotts Prison in Lanarkshire.
Mitchell’s mother, Corinne, has also passed a polygraph test to confirm her son’s alibi that he was at home with her at the time of the murder.
She said: “He says he has never had anything to hide so he didn’t hesitate when he had the chance to take it.
“Luke told me he believes the test is a crucial indication of his innocence to go along with other issues, such as the lack of forensic evidence linking him to the crime,” reports the Telegraph.
Terry Mullins who conducted the test confirmed that Mitchell had passed and was certain it indicated his innocence.
He said: "I can’t believe Luke Mitchell was convicted on the evidence that was available."
The evidence used to convict Mitchell is controversial.
Jones' body was found by Mitchell during a search with relatives and the prosecution said only someone with "guilty knowledge" could have found her so quickly at night in poor search conditions.
Mitchell insists his dog led him to the body.
His alibi, that he was at home at the time of the murder, was called into question when Mitchell's brother, Shane, admitted being at home watching pornography, something he would not have done if he thought someone else was at home.
The prosecution also made much of the fact Mitchell was a fan of Marylyn Manson and had an interest of the "The Black Dahlia" murder case of 1947.
Similarities between the victims of both murders were presented as evidence.
Mitchell unsuccessfully appealed in 2008.
A BBC Scotland Frontline Scotland documentary in 2007 examined the case and suggested another person, a student and known drug user may have committed the murder.
This unidentified person is said to have submitted an essay about murdering a girl in the woods a few weeks before Jones was killed.
A friend of the student also claims to have seen him soon after the time of Jones death covered in scratches.
The case is being reviewed by the Scottish Criminal Cases Review Commission, who will decide if there are grounds for a fresh appeal.
