A new recording of notorious cult leader Charles Manson has emerged, appearing to admit to multiple murders.

Manson’s followers, known as the Manson Family, killed nine people in 1969.

The cult leader led the killings in hopes of starting a race war. He died in prison in 2017.

In newly released audio recorded while in prison and featured in a new documentary, Manson appears to talk about previously unknown crimes.

“See, there’s a whole part of my life that nobody knows about,” Manson is heard saying in one of the tapes, who appear in a new documentary series Making Manson.

“I lived in Mexico for a while. I went to Acapulco, stole some cars. I just got in over my head, man. I’ve been involved in a few murders. I left my .357 Magnum in Mexico City and left some people dead on the beach.

Manson’s associates, as well as his former cellmate Phil Kaufman, are also interviewed.

“Charlie was very good at being bad and not showing it,” Mr. Kaufman says in the show’s teaser.

“Anything that affected his game plan at the time, he crushed it, but he did it with velvet gloves.”

In the series, Manson “narrates the early murders leading up to the murder of the summer of ’69,” according to streaming service Peacock.

The Manson family killed nine people, including Hollywood actress Sharon Tate, who was pregnant, the wife of Roman Polanski.

One of Manson’s young followers, Susan Atkins, stabbed Tate to death and scrawled “PIG” on the door of the house in the actress’s blood.

Four other people in Tate’s home were brutally stabbed to death. The next day, a wealthy Los Angeles couple, Leno and Rosemary LaBianca, were also killed by the clan. The murders became known collectively as the Tate-LaBianca murders.

Separately, Donald Shea, a Hollywood stuntman, and Gary Hinman, an acquaintance of the group, were killed by members of the Manson family.

Manson was not at the scene of the murders, but was still convicted of murder for directing his followers in seven of the murders.

He died of natural causes behind bars in 2017.
