A team of air marshals pursued and ordered the passenger to get on the ground. The passenger did not comply and was shot when apparently reaching into the bag, Doyle said.

Passenger Mary Gardner told WTVJ in Miami that the man ran down the aisle from the rear of the plane. "He was frantic, his arms flailing in the air," she said. She said a woman followed, shouting, "My husband! My husband!"

Gardner said she heard the woman say her husband was bipolar and had not had his medication.
