An official at a central Ohio college says a student who was the subject of intensive search over the weekend apparently died of hypothermia after falling asleep outside.

Denison University student David Hallman III was last seen leaving a downtown Granville restaurant early Saturday. The 21-year-old Erie, Pa., native was found Saturday night outside a garage in a condo complex about a half mile away.

The Columbus Dispatch reports that Laurel Kennedy, vice president for student development, wrote in a memo to the university community that "it appears he had fallen asleep and then succumbed to hypothermia." Police said alcohol may be a factor.

Hallman was a history major who was well-known on the campus of about 2,100 students. He was a former member of the swimming team.
