Trevor John Casper

Trooper Trevor Casper was shot and killed in Fond du Lac while attempting to apprehend a bank robbery and murder suspect at approximately 5:30 pm.

The subject was believed to have robbed a bank in Wausaukee approximately four hours earlier. Approximately one hour after the bank robbery the suspect abandoned the vehicle he was driving, murdered a citizen, and stole a second vehicle in Marinette County.

Trooper Casper located the second vehicle as it was being driven through Fond du Lac and began following it. He was directing other officers to their location when the man pulled into a grocery store parking lot and stopped. The man exchanged shots with the responding officers and Trooper Casper was fatally shot. The subject was also shot and killed by return fire by Trooper Casper.

Trooper Casper had graduated from the police academy only three months prior to the incident and was on his first shift after being cut loose from field training. He is survived by his parents and two sisters.

I vividly remember Trooper Casper from the initial interview and test process in Wausau. When I saw he was killed in the line of duty it devastated me. Such a courageous and brave young man to lose his life at 21 years of age by a maniacal, murderous vermin of society. You will never be forgotten Trooper Casper. RIP Warrior
