Bone-chilling prison audio is set to be released in a new documentary where Charles Manson reveals that he was responsible for more murders, stating he left "some dead people on the beach. The serial killer and his followers were responsible for a spate of high-profile murders in the late 1960s, but the audio suggests there are more victims of the infamous 'Family'.

The Peacock docuseries 'Making Manson' promises to unearth the twisted world of the convicted murderer and cult leader, with Manson detailing "his part in the infamous crimes, as well as his upbringing, criminal youth, and his true feelings about 'The Family."

Manson unnervingly admits on the audio unearthed by the documentary: "I just got involved in stuff over my head, man. Got involved in a couple killings. I left my .357 magnum in Mexico City and I left some dead people on the beach."

Manson, who passed away in 2017 at the age of 83, became infamously known for orchestrating the massacres during the summer of 1969, when his 'Family' brutally murdered Hollywood actress Sharon Tate and several others, reports the Mirror US.

Their reign of terror extended to the subsequent murder of Leno LaBianca, a supermarket executive, and his wife Rosemary in their own home. The murderous spree ended with the arrest of the Manson Family in December of the same year over unrelated car thefts.

The battle over Charles Manson's $1 million estate has been hit with another setback, as three claimants are embroiled in a fierce dispute over the infamous cult leader's assets.

Daniel Arguelles, a 64-year-old Los Angeles real estate agent, is adamant he's Manson's son, while 57-year-old memorabilia collector Michael Channels claims he possesses a will that bequeaths everything to him.

Meanwhile, Jason Freeman, a 48-year-old former MMA fighter from Bradenton, Florida, alleges he's the convicted murderer's grandson. LA Superior Court Judge Ruben Garcia has now approved Arguelles' plea to "bifurcate" his case, setting up a separate mini-trial to determine if he truly is the heir.

This bifurcation will precede a main trial where Arguelles would confront Freeman and Channels. Judge Garcia has pencilled in a 'trial-setting conference' for February 21 next year to schedule the bifurcation trial.

Additionally, he was expected to pass judgement on the legitimacy of the disputed will, which Channels insists bears Manson's signature and excludes his children, but this decision has been deferred to the February hearing.

For years, Freeman seemed to have the advantage in his claim, supported by a 1986 Ohio court ruling that identified him as the son of Manson's deceased son, Charles Manson Jr. However, in 2022, Arguelles joined the fray, claiming he is Manson's biological son from a fleeting affair in 1959.

Judge Garcia had previously recognised Freeman as Manson Jr. 's son but asked for additional evidence linking Manson Jr to Manson Sr To back up his claim, his lawyers later presented Manson Jr's birth certificate, which lists Charles Manson as his father.

Manson passed away due to natural causes on November 19, 2017, at Corcoran State Prison where he spent 47 years on death row.

Some of the cult leader's possessions - such as his guitars, clothes and other personal jailhouse items currently stored in boxes at a storage facility - could be worth thousands to collectors.
