LAPD Chief Charlie Beck requested about eight hours of recordings between attorney Bill Boyd and Charles "Tex" Watson.
The recordings became available when the law firm Boyd worked for when he represented Watson back in the 1960s filed for bankruptcy. The audio remained private until Watson authorized its sale to an author to help cover unpaid legal fees.
Notorious cult leader and mass murderer Charles Manson was convicted in the 1969 killings of pregnant actress Sharon Tate and four others. Watson, the self-proclaimed right hand man of Manson, was convicted of orchestrating the killings.
The concern for LAPD is that there may be more crimes that Watson and other members of the Manson family are connected to, and there may be a reference to those other crimes in the recordings. Investigators are not looking for specific crimes, calling the recordings review just due diligence.
A Texas judge will be hearing that request by the LAPD on Tuesday.
