I agree with the bolded:
"Another point I wanted to bring up, is that IF a person is choosing to disappear themselves, they may not be thinking very logically about anything, to be quite honest. It could have been something that was not planned out very far in advance at all. Maybe she was stressed out about a number of things, been going through feelings of "what should I do?" and actually been planning to get on that flight to begin with, but then had a sudden change of heart and impulsive moment."
I agree and I have been trying hard to come up with a scenario where that might have happened. But I cannot figure out one where she would not have been seen on camera or discovered electronically already.
If she went on as though she was going to fly home, then suddenly decided to change plans, then she would have already walked into the mall and been heading to or been on the metro already. There should be video, if so.
And if she decided spur of the moment, to change plans, why is her luggage back in Spotsy area? How did she get a car and a ride back in that direction if it was a sudden plan to leave the old plans aside? I can't figure out how that part happened.
I want to believe she is OK< and just hiding out after a little mental breakdown. But I don't see how it could have happened in that way without her being caught on camera or seen by someone, etc.
