BENTON HARBOR, Mich. — Police officers responding to a call in Benton Harbor early Tuesday killed a man after he opened fire, authorities said.

Four officers were leaving a home when shots were fired from across the street, said Public Safety Director Dan McGinnis, who doesn’t believe the officers were lured into an ambush after 2 a.m.

“The suspect fired four or five times, and officers returned fire. There was a lull. Two more shots were fired by the suspect, and an officer fired back,” said state police Lt. Chuck Christensen. “Fifteen rounds total.”

The man’s name wasn’t released, but friends and family identified him as Darius Wimberly. He was nicknamed “Karate” because he taught martial arts to children.

“Nothing will ever make me believe he was shooting at the police,” Canvas Smith said. “He was a kind, generous person. I have little kids. He would come by and walk them to the store … If they said he karate-kicked one of them, I’d believe it.”
