Charles Manson’s Granddaughter Recalls Devastating Moment She Learned Family Secret
Sophia Maddox, granddaughter of Charles Manson, describes the phone call that revealed her family’s dark history and her journey to understand it in a new Hulu documentary.
Sophia Maddox was 22 and living in Los Angeles in 2022 when a phone call from her father, Daniel Arguelles, shattered her understanding of her family. Arguelles had been searching for his biological father for years, and when he finally found a lead, he warned Maddox the truth was dark. After pressing him to reveal it, Maddox learned that her grandfather was Charles Manson, the cult leader convicted of orchestrating the 1969 murders of actress Sharon Tate and six others.
“It was a really devastating day,” Maddox told Fox News Digital. She immediately searched Manson’s name online and was struck by the resemblance between her father and the man she had only known as a notorious figure. The revelation upended her life and led her to create the Hulu documentary “My Grandfather Charles Manson,” in which she meets former Manson followers and examines previously unreleased records about his troubled childhood.
Arguelles submitted his DNA to Ancestry in 2015, hoping to identify his father. He had long suspected the man who raised him was not his biological parent and had confronted his mother about his paternity when he was 21. Years later, he matched with Michael Brunner, and DNA testing confirmed they were half-brothers. Brunner is Manson’s son with Mary Brunner, one of Manson’s earliest followers.
Maddox described herself and her father as “normal, working-class citizens” with no criminal records. She said people have asked whether she feared inheriting evil, but she and her father are hardworking artists. Her father showed her his films and modeling photos taken by Richard Avedon, and she grew up with no hint of the dark history that would later surface.
Manson, who died in 2017 at age 83 while serving a life sentence, was a charismatic figure who surrounded himself with runaways in the 1960s. Prosecutors said he sent his followers to kill the rich and famous in an attempt to trigger a race war, an idea he derived from a twisted reading of the Beatles song “Helter Skelter.” Despite overwhelming evidence, Manson maintained his innocence and blamed society.
In the documentary, Maddox explores Manson’s early life, including his birth in 1934 to teenage Kathleen Maddox, his mother’s imprisonment for robbery, and his time in juvenile institutions. Manson later said he was beaten and sexually assaulted while locked up as a juvenile. By the time he was released from federal prison in 1967 at age 32, he had spent roughly half his life behind bars or in juvenile facilities.
Maddox said she was most shocked by how Manson’s adult decisions stemmed from survival mechanisms learned in childhood prisons. She noted that a juvenile justice expert in the film said Manson’s experience at the Indiana Boys School was not exceptional. “That’s how they learned their lessons in survival,” she said. The documentary, she added, was cathartic and gave her a way to process a family history she never expected to uncover.
