Under the authority of the FBI, remains of 9/11 victims at the Pentagon are taken to a temporary morgue in the Pentagon’s north parking lot, where they are photographed, labeled, and then placed in refrigeration. [Stars and Stripes, 9/17/2001; US Department of Health and Human Services, 7/2002, pp. A-47 ; Quartermaster Professional Bulletin, 3/2005] They are then transported to Davison Army Airfield at nearby Fort Belvoir, and from there to Dover Air Force Base, Delaware, where there is a large mortuary created for use in wartime. FBI agents accompany the remains at all points during transportation.

] About 250 people, including 50 medical examiners and 50 members of the FBI’s ‘disaster team,’ work at the mortuary to identify the remains. [Stars and Stripes, 9/17/2001] Remains are first scanned for the presence of unexploded ordnance or metallic foreign bodies. FBI experts then collect trace evidence to find any chemicals from explosives, and also conduct fingerprint identifications. [Pentagram, 11/30/2001] Other techniques used include dental records and X-rays. Tissue samples are sent to an Armed Forces laboratory in Rockville, Maryland, for DNA analysis. [PBS, 9/21/2001] Identification is problematic because specimens are often unrecognizable body parts, and are nearly always mixed with debris composed of aircraft and building materials. [Harcke, Bifano, and Koeller, 4/2002] However, by the time Dover staff formally end their identification effort, on November 16, they have identified remains of 184 of the 189 people who died in the Pentagon or aboard Flight 77, including the five hijackers (see November 21, 2001).
