In his first year in office, President Barack Obama pledged to "collect the facts" on the death of hundreds, possibly thousands, of Taliban prisoners of war at the hands of U.S.-allied Afghan forces in late 2001.
Almost four years later, there's no sign of progress.
When asked by ProPublica about the state of the investigation, the White House says it is still "looking into" the apparent massacre. Yet no facts have been released and it's far from clear what, if any, facts have been collected.
Human rights researchers who originally uncovered the case say they've seen no evidence of an active investigation.
