The brother of the man who murdered British schoolgirl Danielle Jones in 2001 says he never doubted his guilt as he fights to keep the killer behind bars for not revealing the location of her body.
Stuart Campbell, 63, was jailed for life in 2002 for the murder of his niece Danielle but will be eligible for parole this year.
The murderer has never revealed the location of his niece's body, which will be a test for the newly introduced Helen's Law designed to stop killers from being released until disclosing the whereabouts of their victims' remains.
Campbell's brother Alix Sharkey, 64, who currently lives in Barbados, has written a book about his horror at the killing and revealed he never doubted his guilt, saying: 'Within 10 minutes I knew he was lying and there's never been any shadow of doubt in my mind since that moment.'
He told BBC Radio 4's Today Show: 'Towards the end of 2019 I was thinking about my life and then of course I started thinking about my brother and I realised I hadn't thought about him for a long time.

'The papers were full of this stuff about Helen's Law and I guess I hadn't really put the two things together, but when I sat and thought about my brother I realised, "Oh my God, he's planning on keeping his mouth shut, keeping his nose clean, and slipping out of the gates one morning at dawn and just never ever acknowledging what he's done".'
Helen's Law is named after Helen McCourt, a 22-year-old insurance clerk who was murdered in 1988. Her killer, Ian Simms, has never revealed the location of her body.
Under the law, killers could still be released if no longer deemed a risk to the public even if they refuse to disclose information.
But the Parole Board will be legally required to consider whether they have co-operated with inquiries as part of their assessment.

Alix said: 'When I realised he could get out without actually telling the truth, without giving back Danielle's body, in typically British way, I decided first of all, you know what, I'll write an angry letter to the parole board.
'Then I thought I could do better than this, I can also write a letter to Stuart and include my letter to the parole board.
'And then I started realising, this is not enough because he'll ignore it and the parole board won't make it public.'
Danielle left her home in East Tilbury, Essex in June 2001 to catch a bus to St Clere's School in Stanford-le-Hope, Essex - and her parents never saw her again.
Campbell, a father-of-two and body-builder, denied any involvement in his niece's disappearance, but the prosecution produced evidence that he had developed an 'irresistible sexual attraction' for her.
Sharkey believes his brother feels shame for what he did, demonstrable by the fact Campbell has never replied to any of his letters (pictured left beside Campbell in August 1975, aged 18 and 17)
On the 20th anniversary of the schoolgirl's death last month, Danielle's parents Linda and Tony appealed to Campbell to reveal where he hid her body (pictured in 2001)
