Flagstaff police say officers fatally shot an armed person who shot first at officers after they responded to a report of a person brandishing a gun in a Wal-Mart store's parking lot.
A Police Department statement says no officers were injured in the exchange of gunfire Thursday evening.
The statement said the deceased person was male but did not specify the person's age. A department spokesman did not immediately respond to a request for additional information.
According to the statement, three officers involved in the incident have been placed on standard administrative leave pending an investigation by a multi-agency law enforcement team.
