Kate Prout's jailed husband admits 2007 murder and leads officers to where he disposed of body at Gloucestershire farm A wealthy landowner who was jailed for murdering his wife has led detectives to the spot where he buried her body four years ago . Adrian Prout had always denied killing his estranged wife, Kate Prout, in 2007, but was convicted of her murder last year and jailed for a minimum of 18 years. Prout arrived at the farm in a people carrier just after 11.30am and was led out of the vehicle, handcuffed to a police officer. He was transferred into a police car at the farm entrance and driven into a wood. The car emerged from the wood about 25 minutes later, and Prout was put back into the people carrier and driven away. While Prout maintained his innocence, friends called for his release and claimed he was the victim of a miscarriage of justice. But on Thursday afternoon, detectives spoke to Prout in prison, where he finally admitted that he had killed his wife. He said he had buried her body at their home, Redhill Farm, in Gloucestershire, and agreed to point out the precise spot to officers. A detailed search of the area will take place next week. His decision to admit the killing seems to have been prompted by his failing a polygraph test while in prison four months ago. The test was arranged by his fiancee, Debbie Garlick, who had campaigned for his release.His confession may at last provide relief to his wife's family, who had appealed for him to reveal where he buried the body so they could give her a proper burial. Detective Superintendent Simon Atkinson, of Gloucestershire police, said earlier: "Yesterday morning we received some new and significant information in relation to the murder of Kate Prout ? two detectives paid a visit to the prison where Adrian Prout is being held. "Adrian Prout has admitted to those detectives that he murdered Kate Prout ? something which he had always denied ? and has now suggested that he disposed of her body on Redhill Farm, in Redmarley. He has agreed to visit the farm to point out the exact location. "A detailed search of that location will be conducted next week. However, this will be a painstaking process so is likely to take some time. The scene will be guarded throughout the weekend. "We are keeping Mrs Prout's family updated and fully informed of developments." He said the investigation into her death was "challenging and complex, and ultimately led to Adrian Prout's conviction. This latest piece of information does not change that".." Prout, 47, who had a pipe-laying business and ran a pheasant shoot, killed his 55-year-old wife during an acrimonious divorce. A trial at Bristol crown court was told that Kate Prout had increased the amount of money she was seeking in settlement shortly before she vanished in November 2007. Sentencing him to life in prison last February, Mr Justice Davis said: "One of the pieces of evidence that sticks in my mind is Kate Prout used to remember her parents by placing flowers on their grave. I expect her family would like to place flowers on her grave but they can't, and they can't because of you." The Prouts' former home was excavated by detectives in their fruitless search for the body after Kate Prout had vanished. At the time of her husband's conviction, her brother, Richard Wakefield, from Lypiatt, Gloucestershire, said: "Nothing will bring Kate back to us, but we are pleased that justice has been done. We would, however, appeal to Adrian to tell us what happened to Kate and where she is, because we would like to lay her to rest and say our goodbyes." Adrian Prout's lie detector test Prout confessed after failing a lie detector test in prison. Don Cargill, a polygraph expert, said Proute's fiancee, Garlick, paid him to visit Garth prison, in Lancashire, four months ago. Cargill told the Guardian he had set up his equipment in a room next to the prison chaplain's office. He explained how he would monitor Prout's heart rate, blood pressure, the amount he was sweating and how he was breathing as he answered questions. At first, Prout said he did not want to take the test, according to Cargill, who told him that, if he were innocent, the test would help to prove that. Finally, Prout agreed to the test, saying: "I'd better do it for Debbie." Cargill asked him three questions about the murder ? whether if he had killed his wife, whether he had arranged for someone else to kill her and whether he knew where her body was. He replied "no" to each, but Cargill said his equipment indicated that He was lying. Cargill said he told Prout: "I'm looking at a murderer." Prout replied: "Not really." Cargill asked Prout whether he was saying the test was wrong. Prout admitted that it was not wrong. Cargill told him he should "man up" and admit his guilt to Garlick and the authorities. He left the prison and rang Garlick, with whom he had a child, to break the news that Prout had failed the test. "She was destroyed, completely in shock," he said.
