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.

The man exchanged shots with the responding officers and Trooper Casper was fatally shot. The subject was also shot and killed by return fire.
