Good thoughts but I'm pretty sure it's number 2, as there are not hitch-hikers and such in November. This is Mormon, Adventist, desert-junkie, and generally-non-druggie country. Yeah, sure, during the tourist season April to September, there are people wandering up hwy 191 in search of Edward Abbey's "Desert Solitaire" or searching for personal reflection in the magnificent but stark Utah desert. But things really close down at the end of October. It is really really cold in the Utah desert after Halloween. I seriously doubt Michael happened upon ANYBODY that early morning of Nov 27. I think this poor child was spinning due to paranoid schizophrenia or mania, took that Floy exit, went down that road, tried to turn back, went careening into the desert, and then wandered.
Once he's found, I guess the discussion will be how he, or his loved ones, could've gotten him help. Thank goodness the shotgun was confiscated and this didn't escalate to threaten the safety of another person. So very sad.
