A Wisconsin State Patrol trooper has died in a car crash while on duty in Sauk County.
Trooper Anthony J. Borostowski of Tomah lost control of his patrol squad and rolled over on Interstate 90 near Lake Delton about 4:30 a.m. Tuesday, according to sheriff's deputies.
He died at the scene after the squad hit a tree, authorities said.
Investigators are still trying to determine what caused the crash, however they say Trooper Borostowski was parked in a median moments before the wreck, leading them to believe he may have been engaged in a chase.
Trooper Borostowski was in the same class as Trooper Trevor Casper, who was killed in a shoot out with a bank robbery suspect in Fond du Lac two years ago.
"It impacts all of us, but probably specifically that 60th recruit class," said Lt. Col. Steve Krueger with the Wisconsin State Patrol. "That's the second one out of that class, and for our agency, that's number seven now."
Governor Scott Walker released a statement saying:
Our hearts are heavy today as we mourn the loss of Anthony Borostowski who passed away early this morning in the line of duty. Anthony was an outstanding trooper and staff sergeant in the Wisconsin National Guard. I had the honor of meeting him in 2015 when he received the Wisconsin State Patrol’s Lifesaving Award for saving a man’s life by performing CPR. Tonette and I send our prayers to Anthony’s family as they grieve the loss of their loved one. Anthony will never be forgotten.
Walker says an executive order lowering the flags of the United States and Wisconsin in honor of Trooper Borostowski.
