SAR Staff, Hasty Team, RAVEN, SVU, and WCSAR responded to the Mogul area to search for a possible second subject from a one vehicle auto accident. The vehicle left the eastbound lanes of Interstate 80, went over a 100′ cliff, and ended up between the railroad tracks below. During extrication, the subject was positive he had at least one other passenger, possibly two. SAR teams, with the help of RAVEN, searched the area in the vicinity of the vehicle, from the railroad tracks down to the Truckee River. No one was located.
