In a startling revelation this morning, reporters were told that in the months leading up to the violent raid that ended Osama bin Laden’s life, CIA agents had taken up residence next door, in an attempt to verify the identity of a tall, mysterious man they knew simply as “Pacer.”

Even with a satellite hovering overhead and the use of infrared cameras, agents couldn’t pin down who the strange figure was, or why he never left the compound and the mission was ultimately called a failure.

With Osama now allegedly dead, his widow has admitted to reporters that they stayed in the home every day for over five years, which might help explain why he was so difficult to locate for so long.
