Earlier in the day, Kochanski, 43, told reporters that three armed men tried to rob the establishment Thursday night while he and two customers were inside.
He fired at the robbers, killing one of them. Milwaukee police confirmed those details, and the two other suspects fled, Milwaukee police Lt. Mark Stanmeyer said.
In 2008, Kochanski was put in a similar situation, when the former St. Francis firefighter was hosting a Christmas party and men wearing black ski masks and carrying a sawed-off shotgun entered the bar. During that incident, Kochanski fired at the men and they fled.
“All that went through my mind was, ‘Oh my God, I’m going to have to kill these guys,'” Kochanski told the Journal Sentinel at the time.
That time, one customer suffered a gunshot wound.
