VIBORG, S.D. (AP) — Authorities say two teen-age males died and a third was seriously injured in a two-vehicle crash near Viborg in southeastern South Dakota.

The Department of Public Safety says a pickup truck and a car collided at an uncontrolled intersection late Friday when neither vehicle stopped. Both vehicles came to rest in the ditch.

The 19-year-old driver of the car and a 17-year-old passenger in the pickup both died at the scene.

The 17-year-old pickup driver suffered life-threatening injuries and was flown to a Sioux Falls hospital. The department says charges are pending against him.

Names have not been released. The South Dakota Highway Patrol is investigating.
