Charles Manson's granddaughter reveals moment she discovered dark family secret: 'It was devastating'

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. Raised by his mother and stepfather, Arguelles had been trying to identify his biological father when he called Maddox with a startling discovery.
