A volunteer firefighter with the Lake Mills Fire Department is dead after stopping to help a driver on the Beltline near Monona Drive on New Year's Eve. The Dane County Medical Examiner’s Office said preliminary results of an autopsy confirm that 46-year-old Christopher P. Truman of Lake Mills died from injuries sustained in the crash. Truman was a captain with the Lake Mills Fire Department. He had been a captain for more than 10 years. According to the Monona Police Department, Truman pulled over and was helping a driver in a car that crashed on the eastbound side of the Beltline near Monona Drive. While Truman was assisting the driver, another vehicle hit him. NBC15's Tim Elliott spoke with a tow truck driver on Tuesday who saw Truman stopping to help. "I was driving the opposite way west in a truck and I saw him stop and get out of his vehicle," said John Van of Finish Line Towing. "That is ground zero. That is the worst thing that could happen." Police arrested Samuel Patrick Cremers for injury by intoxicated use of a vehicle and homicide intoxicated use of a vehicle.
