Keith Bennett's brother Alan says he thinks he knows where the little boy was buried by Moors murderers Ian Brady and Myra Hindley.
Alan Bennett claims he has located the spot where his brother's evil killers disposed of his body, pinpointed from information gleaned from contacts of Brady.
Twelve-year-old Keith was snatched by Brady and Hindley in June, 1964, vanishing as he made his way to his granny's house in Longsight, Manchester. He was lured into a Mini pick-up by Hindley, and later sexually assaulted and strangled by Brady.
His brother Alan now wants the police to search again for his remains. He says his new information has enabled him to narrow down the part of Saddleworth Moor where Keith was buried to the size of two football pitches.
"Together with my partner, Carol Ann Lee, I have gathered compelling new evidence, much of which we received from interviews with David Smith, chief prosecution witness at the Moors trial in 1966, and also from another source once very close to Brady," Alan told the Mirror.
"The interviews we conducted with him were recorded, together with notes on the maps and photographs we had sent him and which he then discussed in depth as being significant.
"The other source was someone who corresponded with and visited Brady for a long time. Brady asked this person to visit the moor and photograph certain sites. These photographs were taken in the area that ties in directly with the information given by David Smith who was taken just once to the moor by Detective Chief Superintendent Peter Topping in December 1987," Alan said.
"David found it very confusing, as there was 2ft to 3ft of snow on the ground in most places and he was never taken to the relevant area, a specific area of the moor which I would describe as the width of no more than two football pitches."
Alan added that he was 'certain' that a new search would 'bring Keith home'.
Keith's mum Winnie Johnson died in August this year. She had never given up hope she would find her son's body, and had wrote to Brady begging him to reveal where Keith was.
At the time of her death, her solicitor John Ainley said she had 'died without knowing Keith's whereabouts and without the opportunity to finally put him at rest in a decent grave'. Mr Ainley described it as a 'truly heartbreaking situation that this opportunity has now been irrevocably lost'.
