SAN MATEO, Calif. (AP) - A coroner says a teenager in the Asiana Airlines crash was killed when she was struck by a vehicle at the scene. San Mateo County Coroner Robert Foucrault on Friday disclosed the findings of his autopsy on 16-year-old Ye Meng Yuan, a Chinese student. Foucralt said she died of multiple blunt injuries that are consistent with being run over by a motor vehicle. He did not say what that vehicle was. San Francisco Fire Chief Joanne Hayes-White said officials believe the girl was struck by a specialized fire vehicle. Authorities confirmed last week that Yuan was hit by a vehicle racing to extinguish flames that broke out on the Boeing 777. Police said she was on the ground and covered in fire-retardant foam that rescuers had sprayed on the wreckage.
