YANKTON, S.D. (AP) — A Yankton man who died while hunting on the Yankton Sioux Reservation is believed to have accidentally shot himself.

Yankton Sioux Law Enforcement Police Chief Chris Saunsoci says the 54-year-old man was found unresponsive behind his truck Saturday morning by other hunters passing through.

Those hunters attempted first aid but were unsuccessful, and the man was pronounced dead at the scene.

Saunsoci says authorities believe the man accidentally fired his gun, and his death does not appear to be suspicious. He was not immediately identified.
