The last time Melissa saw her father was just before her 16th birthday. "We went to a restaurant, and we were having a normal father-daughter conversation. ... Then the conversation turned to, 'Melissa, I have something to tell you, but you'll tell the police,'" she says. "I didn't know what it was. I thought maybe stealing. I thought misdemeanors. I wasn't thinking murder. I went to the bathroom and tried to calm myself down. I went back to the booth, I sat down, and we resumed normal conversation."

Melissa's father never told her what he was going to say, which Dr. Phil says is a good thing. "Had he completed the conversation, you would have never made it home alive," he says. "He would have had to kill you to protect himself."
