Iowa authorities are investigating after a Bettendorf police officer shot and killed a man who was involved in a domestic dispute.

Bettendorf Police said officers were called to a home around 12:15 a.m. Sunday because of a dispute between a man and a woman but the couple left the area before officers arrived. About an hour and a half later, the man and woman were found in a vehicle.

Police say the woman exited the vehicle and told officers the man had threatened to kill her with a handgun.

Police said the man produced a handgun and refused to comply with officers’ commands. During the confrontation, an officer fired his or her weapon, and the man died at the scene.

The man’s name wasn’t immediately released on Sunday.

Police said one officer was treated for minor hand injuries after the confrontation.

The Iowa Division of Criminal Investigation will review the shooting. The officer involved in the shooting has been placed on administrative leave.
