The documentary My Grandfather Charles Manson premiered on Hulu on July 22, 2026. Co-directed by Sophia Maddox and Alexandra Orton, the film follows 26-year-old Maddox as she discovers through DNA and genealogy testing that the cult leader is her biological grandfather via her father, Daniel Arguelles.

PLAINFIELD, Ind. — Before Charles Manson became the frightening face of the 1969 California murders, he was a troubled teenager stealing, running away and cycling through Indiana’s juvenile institutions.

That largely forgotten Hoosier connection receives new attention in the 2026 Hulu documentary “My Grandfather Charles Manson.” The film, released July 22 and co-directed by Sophia Maddox and Alexandra Orton, follows Maddox after DNA testing indicated that her father, Daniel Arguelles, was one of Manson’s biological sons.

The documentary does mention Indiana—and does more than simply identify it on a timeline. Maddox’s investigation includes a visit to the former Indiana Boys’ School near Plainfield, where Manson was confined as a teenager. The institution and Manson’s allegations about what happened there become part of the film’s examination of childhood abuse, institutional failure and generational trauma.

For Hoosier viewers, that journey provides an uncomfortable reminder: part of the Charles Manson story unfolded not in California’s counterculture, but in Terre Haute, Indianapolis and Plainfield.

From Terre Haute to Indianapolis

Manson was born in Cincinnati in 1934, but much of his early adolescence was spent in Indiana. At approximately 13, he was placed in the Gibault School for Boys in Terre Haute, then a Catholic-run institution for troubled youths.

Accounts of Manson’s childhood describe a boy abandoned by adults, shuffled among relatives and institutions, and already developing a pattern of theft and escape. Manson ran away from Gibault, returned briefly and then fled again.

By 1948, he was living in Indianapolis. According to commonly cited biographical accounts, Manson committed his first documented crime there when he robbed a grocery store. He reportedly used some of the stolen money to rent a room in the city and buy food.

He also briefly worked as a Western Union messenger, but continued stealing. Following further crimes and an unsuccessful placement at Boys Town in Nebraska, Manson was committed to the Indiana Boys’ School outside Plainfield in 1949.

Manson’s years at the Indiana Boys’ School

The Indiana Boys’ School operated west of Plainfield for more than a century as the state’s principal correctional institution for juvenile males. Manson was 14 when he arrived.

His record there was characterized by repeated escape attempts and serious behavioral problems. In 1951, Manson and two other boys successfully escaped. They stole vehicles and robbed service stations while attempting to reach California before authorities arrested them in Utah.

That escape resulted in Manson’s transfer into the federal juvenile system. It also marked the end of his years in Indiana, although imprisonment would remain a near-constant feature of his life.

Manson later claimed that he was beaten and sexually assaulted during his confinement at the Indiana Boys’ School. Those allegations have appeared in biographies and interviews, but many details originate from Manson himself, an often manipulative and unreliable narrator. They therefore should not automatically be accepted as independently proven facts.

The documentary attempts to examine that history through previously unavailable juvenile institutional records. Daniel Macallair, executive director of the Center on Juvenile and Criminal Justice, appears in the film to analyze the records and the institutional environment in which Manson was confined.

Understanding abuse or neglect in Manson’s childhood does not excuse the atrocities committed under his leadership. It may, however, help explain how a neglected juvenile offender became an increasingly dangerous and manipulative adult. That distinction—explanation without absolution—is essential.

A granddaughter confronts an inherited name

The documentary’s central story belongs to Maddox rather than Manson. Her father had spent years attempting to identify his biological father through genealogy research. A DNA match eventually connected him to Michael Brunner, another man identified as Manson’s son.

The discovery left Maddox confronting a question few people could imagine: What does it mean to learn that one of America’s most notorious criminals is part of your immediate family?

Maddox interviews people connected to the Manson story, including former Manson Family member Lynette “Squeaky” Fromme and prosecutor Stephen Kay. She examines Manson’s youth, his years in prison and the control he later exercised over his followers.

The film also documents the emotional strain the investigation placed on Maddox’s relationship with her father. It is ultimately as much a story about identity, family secrecy and inherited trauma as it is another retelling of the Manson murders.

The documentary has received mixed reviews. Some critics have praised its personal examination of generational trauma, while others argue that it gives Maddox’s emotional journey too much prominence and occasionally risks directing excessive sympathy toward Manson. Those criticisms are worth considering, especially because the suffering of Manson’s victims must remain at the center of any responsible account of his crimes.

Indiana’s place in the Manson story

Manson did not commit the crimes that made him infamous while living in Indiana. The Tate-LaBianca murders occurred in Los Angeles in August 1969, approximately 18 years after his final escape from the Indiana Boys’ School.

Manson was convicted of murder and conspiracy for directing and participating in the criminal enterprise, although his followers carried out most of the killings.

Nevertheless, Indiana was where some of his earliest criminal behavior was documented and where his antagonistic relationship with institutions became firmly established. Terre Haute, Indianapolis and Plainfield were important stops along the path that eventually led to California.

The film’s Indiana scenes also raise broader questions about juvenile justice. What obligation does the state assume when it confines an abused or neglected child? Can harsh institutional discipline transform delinquency into something more dangerous? How should historians evaluate allegations made by someone as dishonest and manipulative as Manson while still investigating whether institutional mistreatment occurred?

There are no simple answers, and Manson’s later crimes cannot be laid at Indiana’s feet. Millions of young people suffer abandonment, poverty or mistreatment without becoming violent criminals. Manson remained responsible for the choices he made and the deaths he orchestrated.

Still, “My Grandfather Charles Manson” reminds Hoosiers that the story did not begin at the Spahn Ranch or in the Hollywood Hills. Long before America knew his name, Charles Manson was a lost, delinquent and increasingly dangerous boy moving through Indiana’s streets and reform schools.

The former Indiana Boys’ School therefore occupies a grim but historically important place in one of the country’s most notorious criminal biographies.

“My Grandfather Charles Manson” is now streaming on Hulu in the United States and Disney+ internationally. Hulu’s official film page⁠ describes the documentary as Maddox’s investigation into her grandfather’s life, while A&E’s background report⁠ confirms that it includes visits to the Indiana reform school Manson attended.
