San Francisco fire officials say one of the victims of Sunday's Asiana Airlines plane crash at the city's airport may have been run over by an emergency vehicle on the tarmac.
The body of a 16-year-old girl was found on the runway by the burnt-out plane near an escape chute. A post-mortem is expected to give more clues as to how she died.
It has also been revealed emergency crews entered the plane twice while it was on fire, rescuing five people who couldn't slide down the evacuation chute.
Two Chinese teenagers died and more than 180 people were injured when the Boeing 777 crash-landed after hitting a seawall at the end of the runway.
Air safety investigators, meanwhile, say initial inquiries suggest the jet was flying 25% below its intended air speed on approach. The pilots tried to abort the landing seconds before the crash.
Asiana says the pilot at the controls was still training on Boeing 777s and his supervisor was making his first flight as a trainer.
