PORTLAND, Maine (AP) — Maine police say they have recovered from Portland Harbor the body of a Harvard Business School student who disappeared while celebrating his upcoming graduation with two friends. Divers returned to the harbor Tuesday after finding clothing Monday belonging to 31-year-old Nathan Bihlmaier of Cambridge, Mass. Police said his body was recovered around noon Tuesday. 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.
