Charles Manson admitted to additional murders in newly revealed phone call from prison

Serial killer Charles Manson confessed to murders before he became the leader of the notorious Manson Family cult, chilling new audio from a prison phone call reveals.

“There’s a whole part of my life that nobody knows about,” Manson, who died in 2017, says in a phone call from prison in a short teaser clip from Peacock’s upcoming docuseries “Making Manson.”

“I lived in Mexico for a while. I went to Acapulco, stole some cars,” he continues in his chillingly calm voice. 

“I just got involved in stuff over my head, man. Got involved in a couple of killings. I left my .357 Magnum in Mexico City, and I left some dead people on the beach,” he said.

Manson spent more than 45 years in prison after he was convicted of directing his “Manson Family” clan of troubled, mostly female, followers to kill at least seven people in California in the summer of 1969. 

The dead included actress Sharon Tate, the pregnant wife of director Roman Polanski, who was stabbed 16 times.

The cult leader did not commit the murders himself, but rather convinced his followers to kill.

The new three-part docuseries dives deep into 20-years’ worth of never-before-aired conversations in which Manson talks about his childhood, life of crime and his time as a commune and cult leader from the late 1960s to the early 1970s, according to Peacock.

Before the notorious slayings, Manson spent much of his teenage and early adult life in and out of institutions and prisons for various crimes, including rape and theft.

At a parole hearing in 2012, it was revealed that Manson had coldly told one of his prison psychologists: “I’m special. I’m not like the average inmate. I have spent my life in prison. I have put five people in the grave. I am a very dangerous man.”

“I am crime,” Manson proudly proclaimed during a collect call to The Post from prison in the mid-2000s.

His parole was denied.

The teaser trailer reveals part of an interview with Manson’s former cellmate Phil Kaufman, who described what it was like to live with the killer.

“Charlie was very good at being evil and not not showing it,” he revealed. “Anything that detracted him from his game plan at that time, he would squash it, but he did it with velvet gloves.”

In the decades since the murders, Manson has become an icon for troubled youth and a fixture in pop culture.

He died from natural causes behind bars in November 2017 at the age of 83.

The docuseries premiered on the streaming platform on Nov. 19.
