Authorities think they may have solved the mystery of a Chicago theology student who disappeared on a hiking trip more than two years ago.
Searchers in Colorado have discovered human remains around 11-thousand feet up the side of a mountain, and nearby found the remnants of a campsite that still contained a credit card and other personal effects belonging to James Nelson.
Officials believe Nelson may have suffered altitude sickness and wandered away from his camp. Foul play is not suspected.
