I have to admit, I do wonder. Unsurprisingly, I've always had a problem with unanswered questions.

[he's got a little map he picked up from a rest stop on the way in. not too far from where they found her, really.]

Strange place for it, too, the interstate into and out of town. Could've been coming from or going to anywhere.

[like that other dot on the map where she went missing in the first place. he should really talk to the boyfriend.]

I guess the most likely answer is the town on the other side of the lake where she and her boyfriend got into the crash, but that really just raises more questions.
