FILE - In this July 6, 2013, aerial file photo, a firefighter stands by a tarpaulin sheet covering a body near the wreckage of the Asiana Flight 214 jet after it crashed at the San Francisco International Airport in San Francisco, Saturday, July 6, 2013. The parents of Ye Meng Yuan, the 16-year-old girl who died after being struck by two San Francisco Fire Department rigs at the scene of this crash have filed a legal claim against the city. A precursor to a lawsuit the claim says firefighters knowingly abandoned Ye Meng Yuan "in harm's way" after the crash and that the fire department failed to train its employees to avoid hitting victims at disaster scenes.
