Ian Brady, the Moors Murderer who has died aged 79, refused to reveal where he buried Keith Bennett as police tried to prise the secret from him as he lay dying.The bed-ridden killer, who tortured and killed five children with his lover Myra Hindley, died at a secure mental health hospital on Monday night after spending more than five decades behind bars.It emerged on Tuesday that officers had attempted to secure deathbed information from terminally-ill Brady, who had never revealed where he and Myra Hindley buried 12-year-old Keith. Ian Brady and Myra Hindley on the moors where they buried their child victims “Despite her personal appeals directly to Brady and via my office, Brady had persistently ignored the wishes of a grieving mother.”Bed-ridden Brady was being held at a high-secure hospital in Merseyside after torturing and killing five children with Hindley. In 2013, Brady asked to be moved to a Scottish prison so he could not be force fed, as he could be in hospital, and where he could be allowed to die if he wishes.His request was rejected after Ashworth medical experts said he had chronic mental illness and needed continued care in hospital.In February, he was refused permission to launch a High Court fight to have the lawyer of his choice representing him at a tribunal where the decision would be reviewed. Terry Kilbride, the brother of victim John, said he will still have to deal with the “nightmare” Brady has left behind.He told the Sun: “It’s a lot to take in. It’s been years and years of anguish and pain for us and the families of the victims.”But nothing will change. He’s dead but we will have to still live with the nightmare that he left behind. He’s ruined our lives all these years and he’ll still ruin it even though he’s gone. I feel numb.” Shortly before she passed away in a hospice aged 78, it emerged that Brady allegedly wrote a letter to her with strict instructions that it should not be opened until after his death. At the time of Mrs Johnson’s death, family solicitor John Ainley said: “She was convinced Brady knew where her son was buried and told me she wanted the search to continue to find Keith. The crimes of Brady and Hindley – who died in prison in 2002 – shocked the nation as details of how the pair snatched children off the street, abused and tortured them to death were recalled during their trial.Brady escaped the hangman’s noose as the death penalty was abolished just months earlier and was handed three life sentences. His death, hours after he was urged to “do the right thing” and reveal where the last of his child victims is buried, means he takes some of his secrets about the horrors to his grave.Brady was jailed for the killings of John Kilbride, 12, 10-year-old Lesley Ann Downey and Edward Evans, 17, in 1966.He went on to admit the murders of Pauline Reade, 16, and 12-year-old Keith Bennett. Mr Kilbride added that there were no other words to describe Brady apart from “a murderous psychopath”.

I don’t know.” Police use sniffer dogs on Saddleworth Moor to search for Keith Bennett in November 1986Credit:PA It was, I suppose, quite a moving sort of situation…. he was obviously well aware that his death was imminentRobin Makin, Ian Brady’s solicitor-advocate “The police spoke to me in the course of the evening, and they were trying to have access to his papers,” Mr Ainley told Good Morning Britain.”That’s difficult without consent from his solicitors and a court order. [The police] were trying, I think, to implore Brady at this very late stage to pass on any information or documents to them so they could carry out a meaningful search of the moors.” He said: “He did go to the Moors a long time ago and I suspect that if there had been information for him that he could have provided, he would have provided it then.”He added: “I would very much hope that the remains can be found, but unfortunately I haven’t got any information that’s going to assist.”Mr Makin said he had seen Brady about two hours before his death.He said: “It was, I suppose, quite a moving sort of situation. I got a call that he wanted to see me, he was obviously well aware that his death was imminent.”He said they discussed Brady’s legal wishes and arrangements for his funeral.

But he is said to have refused to disclose the location of the grave in his final hours, dealing Keith’s family a final insult.According to John Ainley, the Bennett family lawyer, detectives were “imploring” Brady to pass on information on his deathbed. It came as it emerged that the secret of where Keith, the final Moors Murder victim, is buried might be contained in a letter Brady reportedly wrote with instructions for it to be opened after he died.Keith’s mother, Winnie Johnson, died in 2012 without being able to lay her son to rest, having fought tirelessly to find him and give him a Christian burial. Brady’s legal advocate at the time, Jackie Powell, claimed the letter existed during a television documentary.She claimed the sealed document was addressed to Keith’s mother and was to be opened in the event of Brady’s death, adding that it might contain “the means to her possibly being able to rest”.However, it is understood that the letter has never been found.Speaking on Radio 4 on Tuesday morning, Brady’s solicitor-advocate Robin Makin said he would be “very surprised” if Brady had had any useful information about where Keith’s body was buried.The Liverpool-based solicitor said the whereabouts of the remains did not come up in conversation – and that he had never asked him about missing Keith.
