Trooper Trevor Casper was shot and killed while trying to apprehend a neo-Nazi career criminal.
The Nazi had 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 Nazi exchanged shots with the responding officers, killing Trooper Casper - and when the bullets had settled, Trooper Casper and the Nazi had fatally shot each other.
