He definitely been found? Only he's still reported as missing everywhere I look. Seems odd to be above the fold on lots of fairly sizeable news sites and not get an update all day.
The guy at work hasn't heard any more since this morning. So waiting for confirmation would seem prudent. Certainly the news sites, as you say, tell a different story. Intriguing.

Apparently he's been found. On an air strip now. (Someone at work knows him).
