MOSCOW, Idaho --  The University of Idaho student from Hailey who went missing after leaving a fraternity party Saturday night and found dead Monday afternoon likely died of hypothermia. Moscow Police say the body of 18-year-old Joseph Wiederrick was found by trackers with the Latah County Search and Rescue Team under the Paradise Creek bridge five miles from campus. KTVB reports Foul play is not suspected in his death. However, alcohol is thought to be a factor. Wiederrick was last seen Saturday night at a party at the Sigma Alpha Epsilon fraternity house.

Authorities believe Wiederrick left the fraternity party and walked about five miles in the opposite direction of his dorm, apparently knocking on the doors of random homes. Investigators believe the teen kept wondering and eventually fell down an embankment into a nearby creek. Wiederrick may have used the bridge for shelter were authorities found him.  Officials suspect Wiederrick had been drinking at the fraternity party. He says officers are still investigating who supplied alcohol to the teen, and whether charges will be filed in the case.
