Re: thoughts that CS might have woken up and wandered at the campground - I don't think so as her sleeping bag was gone too. It sounds like he just scooped her up, sleeping bag and all. It was probably quick. It seems he didn't take the time to separate her from her sleeping bag.
As for the speculation that TK may have wanted a daughter of his own - I can't for the life of me figure out why he took a white child who looks nothing like him, unless he planned to keep her hidden away for years.
I think this is something more sinister and that his online fantasy world was some sort of catfishing setup. Maybe he finally got brave enough to take a child after years of planning and fantasising. There are too many creepy things on his FB that make him look like he's "protesting too much."
ETA: I forgot to mention that the windows were blacked out and there was allegedly a lock on the
outside of the room CS was in. That is some sinister ****.
