Sorry, but best I can do is tell you it was "nearly" the exact same thing. His group had hunted one side of the road, hard for several days and had seen nothing.
They were sitting around camp, and he gathered up his stuff, and stated he was going to look around on the "other side" of the road for a bit. And he totally disappeared. There was a massive search. It was "definitely" last fall. That is everything that I know. The news reporters/stations just stop covering these type events after enough time. So, it just ends up as a failed search.
