Investigators combed through the debris and were confronted with unusual evidence: the toilet and baggage compartment had been smashed into fragments. Shards of metal riddled the inside of the toilet door, while the other side of the door was free of the metal fragments. The tail section had been severed just aft of the toilet and was found mostly intact almost a mile away from the main wreckage. On November 16, 2017, the Federal Bureau of Investigation (FBI) declassified 324 documents related to the investigation.
