UPDATE:
Governor Scott Walker released a statement identifying the Wisconsin State Patrol Trooper killed in the crash as Anthony J. Borostowski of Tomah.
“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.”
An executive order lowering flags to honor Trooper Borostowski will come, according to Walker's release.
