Context of 'January 2004: DNA Tests Indicate Hijackers Could Be Middle Eastern or European'

This is a scalable context timeline. It contains events related to the event January 2004: DNA Tests Indicate Hijackers Could Be Middle Eastern or European. You can narrow or broaden the context of this timeline by adjusting the zoom level. The lower the scale, the more relevant the items on average will be, while the higher the scale, the less relevant the items, on average, will be.

The Bundeskriminalamt (BKA), Germany’s federal anticrime agency, obtains a DNA sample for one of the 9/11 hijackers, alleged Flight 93 pilot Ziad Jarrah, after a search of the home of his girlfriend, Aysel Senguen. After the BKA sends the sample to the FBI, the bureau matches it with the DNA profile of one of four sets of unknown human remains recovered from the site in Shanksville, Pennsylvania, where Flight 93 crashed. According to an FBI report provided to the 9/11 Commission, presumably sometime between 2003 and 2004, no relatives of the alleged 9/11 hijackers provide the bureau with DNA samples for comparison.

Human remains from the Flight 93 crash site are moved to a temporary morgue that has been set up at the Pennsylvania National Guard Armory, several miles away in Friedens. High-tech mortuary equipment has been brought to the armory in a tractor-trailer. [Pennsylvania Emergency Management Agency, 9/12/2001 pdf file; WTAE-TV, 9/13/2001] 75 to 100 specialists, including pathologists and fingerprint experts, are involved in the attempt to identify the remains. Forensic anthropologist Dennis Dirkmaat says that because the remains have suffered “extreme fragmentation,” most will need to be identified using DNA analysis. [Washington Post, 9/14/2001] When remains cannot be identified at the temporary morgue, samples are sent on to the Armed Forces DNA Identification Laboratory in Rockville, Maryland, where samples from the Pentagon crash are also being analyzed (see September 11-November 16, 2001). [Pittsburgh Post-Gazette, 9/25/2001; Stars and Stripes, 10/8/2001; KCRA, 12/20/2001] By December 19, the remains of all 40 passengers and crew from Flight 93 have been identified, using fingerprints, dental records, and DNA. Investigators have, by a process of elimination, also been able to isolate genetic profiles of the four hijackers. [Pittsburgh Post-Gazette, 12/30/2001; DMORT National News, 1/2002; Associated Press, 2/26/2002; Stripe, 9/20/2002] Searchers recovered about 510 pounds of human remains at the crash scene, equaling about eight percent of the total bodyweight on the plane. According to Somerset County Coroner Wallace Miller, everything else was vaporized. [Washington Post, 5/12/2002; Age (Melbourne), 9/9/2002; Canadian Press, 3/28/2004]

The remains of all but one of the people on board Flight 77, including the hijackers, are identified. However, the identities of the hijackers have still not been confirmed through their remains, and the FBI does not provide DNA profiles of the hijackers to medical examiners for identification. [NFPA Journal, 11/1/2001; Washington Post, 11/21/2001; Mercury, 1/11/2002] As of mid-2004, there still have been no reports that the hijackers’ remains have been identified by their DNA, except possibly for two unnamed hijackers.

The Armed Forces DNA Identification Laboratory logo.The Armed Forces DNA Identification Laboratory logo. [Source: Armed Forces Institure of Pathology]The Armed Forces DNA Identification Laboratory (AFDIL) publishes a report on the examination of DNA of the presumed hijackers of Flight 77, which hit the Pentagon on 9/11, and Flight 93, which went down near Shanksville, Pennsylvania. The hijackers’ DNA is identified by a process of elimination, i.e. it is presumed to be that which does not match the samples provided by the passengers’ relatives. Samples are not requested from the hijackers’ families (see After September 11, 2001), but it is determined that the DNA may have come from Middle Eastern men, although in two cases current but not very comprehensive databases indicate they are more likely to come from Europeans. Also, the DNA samples from the Pentagon indicate that two of the presumed hijackers may well have been brothers. Presumably this refers to Nawaf and Salem Alhazmi.
