A one-vehicle crash Thursday afternoon north of Deadwood killed a 9-year old boy and hospitalized a 40-year old man.
Names and the relationship of the victims have not been released, pending notification of family.
The South Dakota Highway Patrol says the preliminary investigation shows a pickup was southbound on Hwy 85 when it left the roadway, went into the ditch, and rolled.
The boy was thrown from the pickup and was pronounced dead at the scene. The man was taken to a Rapid City hospital with life-threatening injuries. Neither was wearing a seat belt.
