From Fox News:
In 2022, Sophia Maddox received a phone call that upended everything she thought she knew about her family and sent her searching for answers about one of America’s most notorious criminals.
At the time, the 22-year-old aspiring filmmaker and actress was living in Los Angeles, juggling odd jobs to make rent, while her father, Daniel Arguelles, was searching for answers about his own past. “‘Is it Ted Bundy?'” she recalled. “He said, ‘Bigger. Think of the biggest movie you know and the biggest director you know.’ And I thought of the movie ‘Once Upon a Time… in Hollywood.’ I was trying to remember the name mentioned in the film. And then I realized who it was: Charles Manson.”
