I think folks are just trying to figure out if those stock photos are of the actual cars.
It could all be gossip. Other than 2 news sites (the radio station and the one newspaper article) that have mentioned that Erin had a marine boyfriend... No one knows for sure. It could be false, but "sources" have told the reporters this information. There is a facebook page where others also gossip. Some of those people claim to know the people involved or that they've heard it from others that do. So far, a lot of their information has been proven later on to be true.....but I really don't know if it's true or just a really good guess. I *think* it's been suggested by a few people that the family is holding back information (or maybe you could call it whitewashing). Again, I don't know why, that's just what I've understood. They delete a lot of comments and questions from people. I don't remember hearing if anybody in Erin's family has commented on the "affair" yet, but I haven't heard any of them make any statement about it.
I hope that helps. This is just my take/opinion on the events that have happened.
