(upbeat music) Auburn Alabama is home to Auburn University, which is a major football school. In a college town, it happens that students sometimes may go often, you know, they may be missing for a little while, but they come back. - Lori was a student at Auburn University, and she had recently graduated. - June 10th, 2006, which is the fateful day in Lori's life. - We were gonna have drinks at my house. We were gonna have rum runners, I believe, and watch a movie and just kind of hang out, do girl time. She called me around 6.30 and said, I'm gonna stop by the store, pick up the drink mixes, and then I'll be headed to your house. And then the phone rang about 30 minutes later, it rang once or twice, I answered, no one was there. - How many times had she simply not showed up and not called you? - Never. - My daughter was a very good person, a kind person, a loving girl, a very studious student. She loved sports, loved her dog. She had a little Yorkie named Peanut, that was her baby. - When did you realize that something was wrong? - I was at work, a lady called, I believe it was her boss, and she told me that I just wanna tell you, your daughter, Lori, has not showed up for work, and right away, bells and whistles went off. My called her and she didn't answer her phone. - I called her house several times, left voicemails on her home answering machine. - You go over to her mobile home. - The door was unlocked, which was not like her. The air condition was running, her dog, Peanut, was in the crate, we walked through the house, she wasn't there. - What are you thinking? - Something's terribly wrong. There is no way she would have left Peanut. - This is it. It's about 4.40 AM, four days after Lori is missing, the car was right here, dead in the center. And engulfed in flames was Lori in this car. Lori was not in the vehicle. - There was no trace of her, whatsoever. I mean, none. - Just vanished. - Just vanished. - And nobody knows what happened to Lori Slazinski.
