Salon began investigating burial operations at Arlington National Cemetery in the spring of 2009. In a series of reports since, then Salon has exposed cases in which officials found unknown remains in graves that were supposed to be empty, buried a service member on top of another, and discovered
an urn in a dirt landfill, only to mark it as "unknown" and quietly bury it in an isolated corner of the cemetery. The series also documented hundreds of missing headstones in one historic section of the cemetery.
In response to these and other revelations, the Army launched an investigation. In June 2010, John Metzler Jr., Arlington's superintendent, and his deputy, Thurman Higginbotham were stripped of their their authority, and Army Secretary John McHugh appointed a commission led by former Sens. Bob Dole, R-Kansas, and Max Cleland, D-Ga., to oversee the cemetery.
