A search for a Harvard Business School student from Kansas who disappeared while celebrating his upcoming graduation with two friends has turned up a body in Portland Harbor.

Divers returned to the Maine harbor Tuesday after finding clothing Monday belonging to 31-year-old Nathan Bihlmaier (BILL'-mair) of Cambridge, Mass. Portland spokeswoman Nicole Clegg said a body was recovered around noon Tuesday, but officials haven't confirmed the identity.

Police say Bihlmaier was separated from friends after being asked to leave a waterfront pub at 12:20 a.m. Sunday because he was intoxicated. He later failed to return to his hotel.

The Portland Press Herald says Bihlmaier is a native of Osborne, Kan., and a University of Kansas graduate.

His wife is pregnant with their first child. He was due to graduate Thursday.
