SANTA CLARITA – A 19-year-old Valencia man died Sunday after he fell off a freeway overpass while trying to avoid an oncoming car after he had exited his vehicle following a crash, authorities said. California Highway Patrol officers found the body of David Hairston III at 4:50 a.m., about 25 minutes after his Ford Escort collided with a Honda Civic on the rain-soaked northbound Interstate 5 at Gavin Canyon Road. Hairston and a 49-year-old Reseda man had collided, and their vehicles remained in the freeway lanes, police said. Hairston’s vehicle was sideways. Soon after, Phoebe Wong, 55, of Valencia was headed toward the scene and apparently could not see Hairston’s car and hit it, police said. Hairston, who was out of his car, jumped onto the overpass to avoid getting hit by Wong. He then slipped in the wet conditions and fell onto The Old Road below, according to a CHP accident report. Nobody else was seriously injured.
