Secret budget documents show that a U.S. military laboratory in Afghanistan analyzed DNA from Osama bin Laden's corpse and confirmed his identify shortly after he was killed by a Navy SEAL team.
The Pentagon denied more than a year ago it had any records of these tests in a response to a Freedom of Information Act request filed by The Associated Press a day after President Barack Obama announced bin Laden's death.
The Washington Post reported Thursday that classified intelligence budget files provided by National Security Agency leaker Edward Snowden state that a forensic intelligence laboratory run by the Defense Intelligence Agency performed the DNA testing. The Post reported that the tests "provided a conclusive match."
The AP's request for records submitted on May 2, 2011, included DNA and facial recognition tests performed to ensure the body was bin Laden's, all videos and photographs taken during the raid on bin Laden's compound in Abbottabad, Pakistan, the death certificate and other records related to the mission.
In a March 2012 response, the Defense Department said it could not locate any of the files.
The AP reported in July that the nation's top special operations commander, Adm. William McRaven, had ordered military files about the raid purged from Defense Department computers and sent to the CIA, where they more easily could be shielded from ever being made public.
The secret move appeared to have sidestepped federal rules and perhaps the Freedom of Information Act as well. The CIA has special authority to prevent the release of "operational files" in ways that can't effectively be challenged in federal court.
Spokesmen for the Pentagon and CIA denied the move was intended to avoid the legal requirements of the FOIA. The bin Laden mission was overseen by the CIA, they said, which meant the records about the raid should be housed with the spy agency.
The CIA has not responded to a separate request for many of the same records about the bin Laden mission the Pentagon said it could not find.
