Two civilian women and an officer were injured by the shooter, who Eddy identified Saturday as 77-year-old John Drake, of nearby Mullan, Idaho.

Eddy said he didn’t know Drake’s motive, and he’s “not sure we ever will.”

He said Drake shot two women who were sitting in a pickup outside the sheriff’s office, in the legs. He initially said an officer was shot in the ear inside the sheriff’s office but clarified Saturday that the officer, who law enforcement has not identified, got hit in the ear with a glass shard caused by Drake’s gunfire.

Eddy said all three victims’ injuries were minor. Drake had several guns with him at the time of the shooting, he said.

Eddy said Saturday that no one ever expects someone to come into the sheriff’s office and open fire.
