Peacock's docuseries, Making Manson, presents new interviews with former Manson Family members Dianne Lake and Catherine Share. They recount their experiences living at Spahn Ranch after the Tate-LaBianca murders, describing the Family's actions following the killings, including their attempts to cover up the crimes and Manson's increasingly erratic and threatening behavior. The series also includes rare prison recordings of Manson himself. Lake and Share detail how they initially remained loyal to Manson out of fear, but eventually left the group after his arrest and the subsequent convictions. Their testimonies offer a compelling perspective on the aftermath of the infamous murders and the psychological manipulation within the Manson Family.
