In 2017, FOIA documents on the investigation into the death of Al Amri revealed that he had been found hanging in his cell with his hands tied in a "snug" fashion behind his back. According to the clerk in charge of the computer logs that tracked detainee movements, Al Amri had been with an interrogator in the hour prior to his death. But other witnesses told NCIS the interrogation had been cancelled that morning, either by the interrogator, or by Al Amri himself. The Naval Criminal Investigative Service (NCIS) investigator that examined the death scene found it difficult to understand how this prisoner could have killed himself in the time allotted while he was under surveillance. NCIS concluded Al Amri had stood upon a folded bed mattress in order to reach the air vent to which he presumably attached the rope of his jerry-rigged noose (made from bed sheets). The air vent itself was over eight feet above the floor of the cell. Despite the fact that the detainee had not supposedly met with an attorney, documents from the NCIS investigation state there were materials of a confidential attorney-client nature in Al Amri's possession at the time of his death, and these were turned over to the Judge Advocate's Office at Guantanamo.
