I keep seeing something from the movie "Cars". ALso New Hampshire instead of Maine. I am also getting a sense of mild autism and a custody issue,. There were rocks involved, and a pick up truck. And a dirty, wet camouflaged coat. Thats all I have. sorry.

and the name Patrick

There's a pic here I posted of his lightning mcqueen sneakers. He was weara camo type jacket as well. A witness also saw a blue toyota tacoma leave the area the morning of the day he was found.

NOt his sneakers, not his coat. An additional backpack and fuzzy blanket with "Cars" on it. Also the coat is a man's camo coat like the Hunting kind. The truck I saw was white, not blue, and there was "happiness" in it. Maybe it was his truck at home and not one involved. But it MAY have been involved. I will stress the feeling I got from a rock of some sort. And I too get the feeling this was someone he was comfortable with.
