A Lake Mills Fire Department captain was killed Monday after he stopped at the scene of a crash on the Beltline and was struck by another vehicle, Monona police said. A vehicle crashed on eastbound Highway 12 near the Yahara River bridge at 6:51 p.m., police said. A second car stopped to assist at the scene, and the driver of the second car was struck by a third vehicle before officers arrived to help with the initial crash. Lake Mills city attorney Daniel Drescher confirmed the driver of the second car was Lake Mills Fire Department Capt. Christopher Truman. Truman, 46, suffered serious injuries and was taken to a hospital where he died, the Dane County Medical Examiner’s Office said. Police said the driver of the third vehicle, Samuel Patrick Cremers, was arrested on tentative charges of homicide by intoxicated use of a vehicle and causing injury by intoxicated use of a vehicle.
