LAKE CHARLES, La. - Police in Louisiana say officers answering a domestic disturbance call shot and killed a man who pointed a gun at them and refused to drop it.

Lake Charles Deputy Chief Mark Kraus says 44-year-old Kevin Lau, an Asian-American, died at a hospital.

Kraus says Chief Donald Dixon has asked Louisiana State Police to investigate the shooting.

Kraus says police got an "open phone" 911 call early Sunday and could hear a disturbance. Responding officers were talking with Lau's wife in the front yard when Lau appeared at the door, holding a pistol.

Kraus says officers and Venus Lau heard a gunshot. He says Kevin Lau then came out and pointed his gun toward the officers.

It was not immediately clear how many officers were involved.
