Two people died and another was seriously injured in a one-vehicle crash that occurred early Tuesday morning north of Kennebec.

Names of the three males involved are not being released pending notification of family members. They were the only ones in the vehicle.

A 2007 Dodge Ram 2500 pickup was northbound on South Dakota Highway 273 when the vehicle went off the roadway, went into the ditch and rolled.

All three occupants were thrown from the vehicle. The 18-year-old driver and a 17-year-old passenger were pronounced dead at the scene. A 18-year-old passenger suffered serious non-life threatening injuries. He was taken to the Chamberlain hospital and later flown to a Sioux Falls hospital.

South Dakota’s Highway Patrol continues to investigate the crash. All information is only preliminary at this point.
