A solicitor acting for Keith's mother, Winnie Johnson, has held two meetings with Brady at Ashworth High Security Hospital, where the serial killer has been held since he and his accomplice Myra Hindley were convicted in 1966.
Mrs Johnson, 74, has repeatedly pleaded with Brady to reveal where he buried her 12-year-old son, the only one of Brady's five victims whose body has not been found.
Speaking for the first time about the meetings, which took place last year, David Kirwan revealed that Brady had told him: "I will show you the way." He also said: "I will direct the police."
Keith is believed to be buried in this area
