Police investigating the murder of Robert Blake‘s wife, Bonny Lee Bakley, are requesting tapes of an angry conversation between the couple from The National Enquirer, a tabloid newspaper, on Tuesday. Blake‘s attorney, Harland Braun, said he believes that the cops are “grasping at straws,” Reuters reports. The tapes reportedly capture the 67-year-old actor accusing Bakley of getting pregnant to trap him into marriage and then pressing her to get an abortion. Braun concedes that the taped phone conversations were authentic but claims they proved nothing and that the detectives were still trying to pin the murder on his client, rather than solving the crime. According to the transcripts, Blake was recorded as saying, “You are who you are and you do what you do. If that’s the way you can live and you can live with yourself doing stuff like that its gonna come down on you.” The Enquirer is complying with the police and will hand over the tapes.
