A coroner announced on Friday that a teenager killed in the Asiana Airlines crash earlier this month in San Francisco was killed by a motor vehicle -- likely a fire truck that arrived on the scene to provide assistance -- and not injuries sustained in the crash, according to the San Francisco Chronicle.

The July 6 crash of Flight 214 was caused by pilots striking a sea wall as they neared the San Francisco airport using a "dangerously low and slow approach," according to the Wall Street Journal.

The coroner warned as early as July 8 that the the victim, a 16-year-old Chinese high school student later identified as Ye Mengyuan, had sustained injuries more consistent with being struck by an emergency vehicle than that of a plane crash.

Fire Chief Joanne Hayes-White apologized to the family on Friday.

The Associated Press also reported on Friday that the two as-of-yet unidentified pilots were hospitalized following checkups they received after returning to South Korea this weekend. The Wall Street Journal reported that the pilots fear they will face criminal charges in their home country.
