Misty's father, Charles Upham, first reported her missing. "She had recently changed her medication, so she was sort of having erratic behavior," Charles said to The Hollywood Reporter. "She told me and her mom that we didn't have to worry about her any more. … I thought it sounded suicidal myself, so I called the police. She's always been a suicidal person."
