A Los Angeles television station recently received a tape of the interview with Boyd and author Tom O'Neal.
In the interview Boyd tells the writer that Watson claimed that Manson himself committed some of the other murders.
'A Bunch of Other' Murders
"He told me about a bunch of other people Manson had killed," Boyd said. "He was extremely candid. This was Manson killing other people."
Manson and three of his followers were convicted of the Tate-LiBianca murders and originally sentenced to death. Their death sentences were commuted when California briefly outlawed capital punishment in the 1970s. Conceivably, if Manson were convicted on new murder charges, he could once again face the death penalty.
Boyd said in the interview that he had more than 20 hours of audio tapes of his interview with Tex Watson while he was representing him four decades ago. The Los Angeles Police Department have tried to gain access to those audio tapes which are tied up in the bankruptcy of Boyd's former law firm.
Watson Fights Release of Tapes
The LAPD originally won the right to take possession of the tapes, but Tex Watson appealed the bankruptcy judge's decision, and won a stay, saying that the tapes could become public and do more harm to the victims' families.
Watson asked that the detectives be allowed to listen to the tapes, but not take possession of them. He also said there was no evidence of other murders on the tapes.
Excerpts of the tapes can be heard in a video report by Heidi Cuda of MyFoxLA.com.
