Police in Eau Claire, Wis., shot and killed a knife-wielding man on Saturday morning, officials said. No one else was hurt.

The incident began at 10:51 a.m. when police got a call that a man was acting suspiciously in a hallway of an apartment building on Peters Dr., according to a police news release. The man was banging on doors and causing a disturbance. Several officers responded.

The first to arrive at the complex saw a 25-year-old man in the parking lot carrying a knife, police said. The man acted aggressively as more officers arrived, police said, and “verbal communication was ineffective,” as were beanbag rounds and Taser shocks, the release said.

Failing all else, an officer shot the suspect, and police “immediately began performing life saving efforts,” it said. But he died.

As is customary, an outside agency, in this case the La Crosse, Wis., Police Department, is investigating. No names are yet being released, but police said the officer who fired is a 20-year veteran, now on administrative assignment per normal practice in any such case.
