What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

The flight returned to mia. After landing, aal 1291 conducted an emergency evacuation on the airport ramp due to smoke and fire warnings within the aircraft. During the initial phase of the evacuation a flight attendant was fatally injured.

The aircraft was pressurized when the forward (L-1) door was opened by the fatally injured flight attendant.
