A service will be held this (Monday) evening at Sparta High School to honor the state trooper killed in a traffic crash while on duty. Officials say 34-year-old Anthony Borostowski of Tomah might have been catching up to an offending motorist early last Tuesday when his patrol car veered into a ditch and struck a tree on Interstate-90-94 near Wisconsin Dells. He’ll be remembered at five p-m at Sparta High School, with visitations beginning there at noon. Full police and military honors will follow the service in the school’s parking lot. Borostowski served three tours of duty in the Middle East with the Wisconsin National Guard, and he received the State Patrol’s Lifesaving Award in 2015 for performing C-P-R.
