The South Dakota Highway Patrol says a 40-year old woman was killed and a 22-year old man injured in a one-vehicle rollover accident around 6:00 Thursday evening about 45 miles east of Rapid City.
Names are pending notification of family.
The Highway Patrol both individuals were in a westbound pickup east of Scenic when the driver failed to negotiate a right turn. The pickup went across the centerline, into a ditch, and rolled.
Neither occupant was wearing a seat belt and both were thrown from the vehicle. The woman was pronounced dead at the scene while the man was taken to a Rapid City hospital with serious but non-life threatening injuries.
Since both individuals were ejected from the pickup, investigators have been unable to determine so far which of them was driving.
