I would think, if someone took her, then they wanted to keep her alive.
It gives me hope. I realize that's not always the case, so maybe that is why LE doesn't want to make the suspect feel pressure to do away with her. (Sorry, I have to mention that.) Anyways, LE must be questioning her family, friends, and employer. Don't you think so?
If this was an abduction:
Was it someone she knew?
Someone who had been to the camp before?
An old boyfriend? Someone with a crush or infatuation with her?
A complete stranger that was robbing the place?
Some older perv in a camp around there?
A relative of the person she was caring for?
Someone connected to her new job as a Home Health Aide?
Other ideas?
