Divers with side-scanning sonar are expected to return to Portland Harbor in Maine to search for a Harvard Business School student from Nebraska who disappeared while celebrating his upcoming graduation with two friends.
Divers are scheduled to return to the water after finding clothing Monday belonging to 31-year-old Nathan Bihlmaier of Cambridge, Mass.
Police say Bihlmaier was asked to leave a waterfront pub at 12:20 a.m. Saturday because he was visibly intoxicated. He was separated from his friends and failed to return to his hotel. He was reported missing by the friends on Sunday.
Bihlmaier is a native of Osborne, Kan. and a graduate of the University of Kansas.
His wife is pregnant with their first child and he was scheduled to graduate Thursday.
