A new recording has been released in which notorious cult leader Charles Manson appears to admit to more murders.

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

The cult leader directed the killings in hopes they would spark a race war. He died in prison in 2017.

In a recently released audio recording while he was in prison and featured in a new documentary, Manson appears to speak about previously unknown murders.

“See, there’s a whole part of my life that no one knows about,” Manson is heard saying in one of the tapes: who feature in a new documentary series Making Manson.

“I lived in Mexico for a while. I went to Acapulco, I stole cars. I just got involved in some stuff that’s way beyond my control, man. Was involved in a few murders. I left my .357 Magnum in Mexico and left dead people on the beach.

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

“Charlie was very good at being mean and not showing it,” Mr. Kaufman says in the series teaser.

“Anything that got in the way of his game plan at that point, he crushed it, but he did it with kid gloves.”

In the series, Manson “recounts the early crimes that led to the killing spree of the summer of 1969,” according to the streaming service Peacock.

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

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

Four other people at 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. These murders became collectively known as the Tate-LaBianca murders.

Additionally, 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 nonetheless convicted of murder for leading his followers in seven of the killings.

He died of natural causes behind bars in 2017.
