MIDDLETON, Idaho (AP) — Authorities in southwest Idaho say a deputy responding to a disturbance at a home shot and killed a man who emerged from the home with a pistol.

Canyon County Sheriff Chief Deputy Marv Dashiell says the shooting occurred at about 11:20 p.m. Wednesday east of Middleton. Dashiell in a news release says the deputy fired multiple rounds from his sidearm during the confrontation. He says it's not known if the man fired with the pistol.

Lifesaving measures by the deputy and other emergency responders failed. Names have not been released. Dashiell says the Idaho State Police is the lead agency in a task force investigating the shooting. The deputy has been placed on leave.
