On March 24, 2015, Trooper Trevor Casper, 21 years of age and an eight-month veteran of the Wisconsin State Patrol made the ultimate sacrifice when he lost his life in the line of duty while attempting to apprehend a suspect in Fond du Lac County.
Trooper Casper was following a vehicle driven by a suspect from a bank robbery and murder that occurred earlier in the day. Before backup could arrive, the suspect opened fire on Trooper Casper. Though wounded, Trooper Casper was able to return fire and kill the suspect before succumbing to his fatal injuries.
