There are accusations of "improperly marked graves, faulty records-keeping and other management failures" at the cemetery, which could result in disciplinary action for military officials. From the Marine Corps Times:
Army Secretary John McHugh launched the Inspector General inquiry last November after an internal Army finding that cemetery workers in 2003 discovered a casket without a headstone and confirmed a news report that cremated remains contained in an urn were buried two years ago over an unmarked but occupied grave site.
This isn't the kind of thing we want for our veterans.
