While her daughter is still missing, Maddie Soto’s mother sits down with investigators from the Orange County Sheriff’s Office.
They show her evidence proving Maddie is not alive. They also show her photos from Stephan Stern's phone, removing all doubt about what has been going on between her 38-year-old boyfriend and her 13-year-old daughter.
During the interview, investigators ask the mother about the motive—why would Sterns kill Maddie? Both investigators and the mother wonder: Is it possible Maddie was pregnant?
