Leaked internal United States Army documentation, a death certificate dated 12 December 2002, ruled that his death was due to a direct result of assaults and attacks he sustained at the hands of interrogators of the 519th Military Intelligence Battalion during his stay at Bagram. The document was signed by Lt. Col. Elizabeth A. Rouse of the U.S. Air Force, a pathologist with the Armed Forces Institute of Pathology in Washington DC, and listed as its finding that the "mode of death" was "homicide," and not "natural," "accident" or "suicide"[5] and that the cause of death was "blunt-force injuries to lower extremities complicating coronary artery disease".[6]
