In a newly revealed phone call, cult leader Charles Manson confessed to more murders.

Charles Manson, the notorious cult leader who orchestrated one of Hollywood's most heinous killings, admitted to more murders before leading the Manson Family cult, as revealed in a chilling audio series on Peacock.

A teaser clip of the new series "Making Manson" showcased the confessions, with Manson's voice heard from a prison phone discussing his time in Mexico.

"I lived in Mexico for a while and went to Acapulco. There's a part of my life that nobody knows about, including the fact that I stole some cars," Manson is heard saying in the clip.

"He stated, "I recently found myself in a situation beyond my control. I was involved in multiple murders. I accidentally left my .357 Magnum in Mexico City and unintentionally left some bodies on the beach.""

The docuseries premieres Nov. 19 on streaming service Peacock.

In 1971, Charles Manson was found guilty of nine homicides, including the 1969 murder of pregnant actress Sharon Tate.

According to prosecutors, he aimed to incite a racial conflict, which he allegedly derived from a misinterpretation of the Beatles song, "Helter Skelter."

The Manson murders were a gruesome and terrifying crime. Tate, who was 26 at the time of her death, was brutally murdered by being stabbed and hung from a rafter in her living room. The perpetrators used the victim's blood to write "Pigs" and misspelled "Healter Skelter."

Manson was the master manipulator who convinced others to commit the murders, even though he himself did not carry them out.

On August 9, 1969, the Manson Family, following Charles Manson's orders, brutally murdered five people at the Tate residence: Abigail Folger, Jay Sebring, Voityck Frykowski, Steven Parent, and Sharon Tate, the wife of director Roman Polanski who was away at the time.

Across town, a wealthy grocer and his wife, Leno and Rosemary LaBianca, were brutally murdered the following night.

In the '60s, Manson, a habitual offender who had spent his childhood in and out of jail, attracted a following of runaways and lost souls during the peak of the hippie movement in California. Despite being in his mid-30s, Manson gained a following of mostly women who saw him as a Jesus Christ figure. Many of his followers were teenagers and had strained relationships with their families.

Eventually, the family formed a commune-like community at Spahn Ranch near Los Angeles, where Manson controlled his followers through drug use, organized orgies, and gave them unusual lectures.

Three months after the murders, Manson was arrested and put on trial for murder. After a year-long trial, Manson and three of his followers, Susan Atkins, Patricia Krenwinkel, and Leslie Van Houten, were found guilty and sentenced to death. Another defendant, Charles "Tex" Watson, was convicted later. However, the California Supreme Court struck down the death penalty in 1972, sparing all four defendants from execution and giving them life sentences instead.

On November 19, 2017, at the age of 83, Manson passed away in a California hospital while still serving his life sentence.
