It looks like Arlington is not the only place with issues as Dover has lost some remains and personal effects of the victims of 9/11 (among other issues):
The Port Mortuary at Dover Air Force Base, Del., lost portions of remains of seven victims killed in the Sept. 11 terrorist attacks, according to an independent panel tasked with investigating the mortuary.
Army Gen. John Abizaid, who chaired the Defense Department-created panel in the wake of revelations that remains of troops had been lost or mishandled, declined Tuesday to elaborate on the incidents outlined in the report.
Among the other incidents: a $25,000 payout to the wife of a fallen Marine whose personal effects were accidentally destroyed in January 2007, human remains “misrouted” in 2005 “in a fashion [constituting] dereliction of duty,” and, two civilian cadavers were used that were used in 2009 to “test” crematorium facilities. The investigation also found that the remains from a Navy crew killed during a T-39 accident were cremated and disposed of as medical waste in July 2006 rather than being interred for group burial...
Apparently, the press conference on Dover was full on combat for General Abizaid.
