OSP Troopers and emergency crews responded to this morning’s serious injury motor vehicle cras h involving a Yamhill County Sheriff’s Office patrol vehicle and a passenger vehicle on HWY 18 milepost 40, near McMinnville. According to OSP Sergeant Jesse Orosco, on June 27, 2015 at about 7:17 AM, a 2006 Hyundai Santa Fe, operated by Randy D MANNS, age 46, of Depoe Bay, was traveling eastbound on HWY 18, and for unknown reasons, drifted off the highway into the adjacent ditch. MANNS over-corrected, traveling across the eastbound lane and into the westbound lane of travel where the Hyundai collided head-on with a westbound Yamhill County Sheriff’s Office patrol vehicle, a 2008 Ford Crown Victoria, operated by Deputy Dave MILLS, age 27, of Sheridan. Both vehicles received heavy impact damage and the Hyundai started on fire. Yamhill County Deputy Tim Casey and a Good Samaritan helped get MANNS out of his burning vehicle while OSP Senior Trooper Dan Davis and two other Good Samaritans extinguished the fire with fire extinguishers. MANNS was airlifted to Legacy Emanuel Medical Center in Portland and Deputy MILLS was ground transported to the Salem Hospital, both with serious injuries. On scene evidence indicates that both occupants were wearing their seat belts and the cause of the crash is still under investigation.
