Sad indeed. I have a friend who was notorious for leaving with people. You would go to look for her, start asking questions, and then find out she had left with someone. We have tracked her down many times. At my sister's bachelorette party, we went to the beach and my friend left with a bunch of people in a van, and the whole time, I was asking who they were, for a number, where they were staying, to please get out and come on with us, I was walking by the vehicle, as she left with them, and she didn't come back until the next afternoon. I was so furious with her. It sounds to me as if she met up with somebody and they promised something or whatever, and she ended up outside with no way back in or she could have been kind of led out. I can't believe she was not captured on video. Maybe she never went in at all. Maybe she drank too much and her friends took her purse and ticket and went in without her and left her locked in the car. She woke up, had to go to the bathroom, realized they had taken her keys and purse, tried to get in, couldn't and walked off or -- I don't know. It would seem if that was the case, she would have just sat in her car until they came back or something. It just doesn't seem right, but there are cases where someone meets up with someone and they leave with them, against everyone's wishes, and there is nothing you can do about it. I can't believe no one would go to the bathroom with her. I always go with whoever is going, just so they aren't alone and I am not alone, even now that I am old. I also make sure I tell whoever is staying to stay there until we get back, and I usually leave my purse or something. I hope there is forensic evidence that can point LE in the right direction.
