If you are asking me, I don't know why anybody does anything. What is logical to one may not be logical to another. It makes sense that she may have been on her way to her mothers. It also makes sense that she may have been doing homework later in the evening. Especially since her brother and neighbor claim LE told them that. That was originally what LE supposedly told a reporter. I think it was in their local paper and I wish someone could provide the source. Also the fact that her mom believes her contacts were left behind seems to imply she was home later. There is always a possibility she had a pair that they didn't know about, but if they were sitting in her case in solution and there were no unopened pairs it would appear she wasn't wearing them. She had taken them out and intended to put them back in. If she was going to open a new pair she would have just thrown them in the garbage. Assuming they were disposables. This is what has always been bothering me. If we new for sure, I think it would be very telling,as she wouldn't go anywhere without them in. But we just don't know. In regard to the car, I don't recall that it was definitive that she was expected to pick up her car. I got the impression that there was a possibility her brother would be there with it the following morning. That is why he sent her the text asking if she needed the car. I don't remember any clarification that SHE WAS EXPECTED to pick up the car at her mother's house. That WOULD make a difference, for sure. Can anyone or provide a source that says she was planning on "Picking up the car" as opposed to her brother picking her up for work? It doesn't make sense to me that he would ask her if she " still needed a ride to work"if she was going to pick it up. Wouldnt he have asked her the night before and not last minute before she had to leave for work?
