He said he's 20 miles from Bly. When did somebody look for him?
If an animal got him, the bike would be there in the woods. Getting hit by a pickup truck or motorhome is possible, but how would the driver make everything disappear before a car came along? Maybe he found a better GF. LOL. Could be he just got mugged too I suppose. Don't see a reason for suicide.

Anyway, his videos are way boring with his head in the screen 80% and he's just standing. He could talk and show the ride for way better effect.
