"The remains of five people killed in the terrorist attack on the Pentagon were damaged beyond identification in the massive explosion and fire after a hijacked airliner crashed into the building’s west side, officials said.
Investigators have identified remains of 184 people who were aboard American Airlines Flight 77 or inside the Pentagon, including those of the five hijackers, but they say it is impossible to match what is left with the five missing people.
A team of more than 100 workers at a military morgue at Dover Air Force Base in Delaware used several methods to identify remains but primarily relied on DNA testing and dental records. They formally ended their effort Friday after concluding that some remains were too badly burned to identify.
The fifth unidentified victim was a passenger on the hijacked plane. A spokesman for the FBI declined to disclose the name of the victim.
All 64 people aboard the hijacked plane, including six crew members and the five hijackers, were also killed.
Military officials said they had been preparing families for some time for the possibility that there might not be any remains of some victims.
The remains of the five hijackers have been identified through a process of exclusion, as they did not match DNA samples contributed by family members of all 183 victims who died at the site.
The hijackers’ remains will be turned over to the FBI and held as evidence, FBI spokesman Chris Murray said. After the investigation is concluded, the State Department will decide what is to be done with the remains." -Washington Post (11/21/01); –Arlington National Cemetary (11/21/01)

"Dover Air Force Base morticians have isolated the remains they think are the five hijackers in the Pentagon attack and will keep them as evidence for the FBI, a base spokesman said Friday.
Genetic information from the five does not match any DNA samples on file at the Pentagon or obtained from family members of the crash victims, he said.
Unlike those victims, the institute has no DNA samples from the hijackers’ relatives to compare with DNA drawn from the remains. This has prohibited them from putting names to the remains.
The remains were flown to Dover from the crash scene in the days following the attack.
Maj. Jon Anderson said the hijackers’ remains were identified through a process of elimination." -News Journal (12/15/2001)

"Unidentifiable remains of victims of the September 11, 2001, attack on the Pentagon will be buried in Arlington National Cemetery, the military said Friday.
The September 12, 2002, ceremony will hold special significance for families of five people whose remains have never been identified, said Colonel Jody Draves, a spokeswoman for the Military District of Washington, which oversees the cemetery.
The Pentagon attack killed 189 people: 125 in the Pentagon and 64 aboard American Airlines Flight 77. Remains of the five hijackers on the flight have been separated from those of the victims.
The five victims whose remains have not been identified include: Retired Army Colonel Ronald Golinski, a civilian Pentagon worker; Navy ET1 Ronald Henanway; Rhonda Rasmussen, a civilian worker for the Army; Jack T. Lynch, a civilian worker for the Navy; Dana Falkenberg, a passenger on Flight 77" -Arlington National Cemetery (08/16/02)
