The Army is launching an investigation into operations at Arlington National Cemetery.
Army Secretary John McHugh has directed the Army's Inspector General to look into accountability of some graves and allegations of poor record keeping.
The announcement comes more than a year after cemetery workers buried cremated remains at a grave site that was already in use. They later moved the cremated remains to another site and remarked the original grave. But a Defense Department statement says there have been questions about whether cemetery workers followed proper procedures in correcting the error.
The new probe also comes after an investigation into an unmarked grave discovered in 2003.
McHugh says the investigation will "help ensure America's confidence in the operation of its most hallowed ground."
