I searched for a transcript, but can't find one. The things that stood out to me:
-When asked if he knew if they had made it inside the mall, Richard Wilson (Renee's father) said that they had supposedly been spotted at the mall in Murphy's and a shoe store. Then he added that supposedly there was some tall, skinny guy following them, with "California" on his jacket. Another guest, Sheryl McCollum, mentioned a man coming forward in 1975 saying that he had seen them at a record store and saw a man lingering around or following them. Mr. Wilson did end up clarifying there was only the one gift from home in the car that Renee had brought, so they don't have anything definitive like a receipt that would help clarify where they had gone.
-The letter discussion was what I found most interesting. Mr. Wilson says the letter was brought by Debbie to her parents' house, and they called the police. Police wanted the envelope, so she had to go back and get it. You can tell he doesn't buy anything about the letter. Says the letter, the way it was folded, doesn't fit the envelope. The letter was written in ink and the envelope was written in pencil. Sheryl McCollum says it would have taken a week back then for the letter to arrive, had it been mailed the day before. They think it was hand-stamped and made to look like it went through the mail, when it didn't. They deduce it was hand-delivered by perpetrator, if it was in fact delivered at all. Julie's Aunt, Sandy Harkom, thinks the letter was designed to throw them off. Mr. Wilson says he believes he knows who wrote the letter...Tommy. He says he has seen many samples of his handwriting, and it looks like his. Someone jumps in (I think Sheryl McCollum) and says some analysis showed Tommy at least wrote the envelope, but then they came back and said, "No, you misunderstood." Sorry, this part was confusing, and I'm not sure I'm describing what they said correctly.
