The comment-o-sphere is crying "hoax," but the experts say it's possible. He may have organ damage though.
No doubt the skepticism is fuelled by the fact that he was only a couple of kilometers from the main road. Seems a bit odd.
There are reports that he was unemployed, living out of his car, and dodging debt collectors. Maybe that explains why he did not immediately walk out.
