Armando Gonzales was a sergeant in the Air Force.
Gonzales witnessed the events of flight 549 from the air traffic control tower. When agents Fox Mulder and Dana Scully came to investigate, Gonzales watched partner Louis Frisch answer them with lies he was ordered to tell them. After they left, Gonzales wanted to tell the truth, but Frisch told him not to. Later that day, Gonzales died of a gunshot to the forehead. Frisch was blamed for it. (TXF: "Tempus Fugit", "Max")
