A 20-year-old Iowa man died on May 31, 2014, while in the custody of a Missouri Highway Patrol trooper on the Lake of the Ozarks. Brandon Ellingson, stopped for suspicion of boating while intoxicated, was being transported to a patrol zone office when he fell - or, as the patrol initially said, jumped - from the trooper's boat. His wrists were locked in handcuffs behind his back, and the life vest the trooper had placed over his head soon came off. Ellingson struggled to keep his head above water for several minutes before slipping to the bottom of the lake. Subsequent reporting revealed a series of mistakes by the trooper, a road veteran who had not received proper training to work the water after the Missouri Water Patrol was merged into the Highway Patrol in 2011.
