Arlington National Cemetery is the final resting place for more than 300,000 American veterans and dignitaries.
And officials say they can't be sure just who is buried in some of its graves.
The Army is releasing results of a probe ordered last year after revelations that cremated remains were buried at a grave site already in use. Officials say problems with management and record-keeping at the nation's most hallowed military resting ground have gone on for years, but they're not saying how many burial sites are involved.
In some cases, they say a grave marker wasn't placed soon enough after burial, or records weren't kept updated -- leading to uncertainty about the identities of the deceased at some grave sites.
