Nebraska State Patrol Sgt. Joel Smith picks up debris from a one-vehicle roll-over accident about 7:15 a.m., today, north of McCook on West Third and about one-quarter of a mile west on Road 719. Assisting on the accident scene were personnel from McCook Fire and Rescue, the Red Willow County Sheriff's Department and the Red Willow Western Rural Fire Department, whose crew members rigged a winch line between their fire truck, a fence post and the car to keep the car from sliding into the canyon as ambulance personnel removed the driver. According to Smith's report, Sheree Kerns, 30, McCook, was eastbound on Red Willow County Road 719, swerved to avoid a deer and lost control of her van, which went into the south ditch and rolled before coming to rest upright. She was taken to Community Hospital, where she was treated for injuries sustained in the crash. A juvenile passenger in the vehicle was unharmed and released from the scene.
