A fifteen-year-old died on Thursday, September 11th, of injuries he suffered when the pickup truck he was driving crashed into the side of a semi truck. The accident occurred around 7:40 AM in Adams County. Christian Silva, of Creston, was southbound on Vanilla Avenue, about five miles east of Prescott. He apparently failed to stop at the intersection with 200th Street and collided with a semi driven by John Paxson, 37, of Mt. Ayr. The pickup continued through the intersection but left the road and rolled into the east ditch, landing on its top. The semi continued through the intersection, left the road, and entered the south ditch. Christian died at the scene. Mr. Paxson, who was also injured, was treated and released.
