Two teenage boys badly injured in a two-vehicle collision that killed two others Friday afternoon in Harper County remain in critical condition at a Wichita hospital.

Joshua Campbell and John Eshelman, both 15 and both from Harper, are being treated at Wesley Medical Center. They were in a pickup truck that collided with an SUV at an intersection of dirt roads about a mile south of Harper, according to the Kansas Highway Patrol.

Based on an initial investigation, the pickup — a 2008 Chevy Silverado — and the SUV — a 2004 Chevy Avalanche — entered the unmarked rural intersection of Northeast 80th Road and Northeast 10th Avenue at about the same time. The Silverado “T-boned” the SUV on the passenger side door.

The force of impact shoved both vehicles into a ditch, where they smashed into a gas line and broke a telephone pole about 30 feet away, according to the highway patrol.

Two Harper County teens, 17-year-old Ayron Maurer and 18-year-old Samuel Cook, were killed in the crash. A third teen in the SUV, 14-year-old Colin Nygaard of Anthony, is in fair condition at Wesley.
