Mystery Man on RoofIn the wake of yesterday’s horrific bombing attack at the 2013 Boston Marathon, the web seems consumed by one question…

Who’s the mystery man on the roof?

In photos captured from the chaos after the blasts occurred, you can clearly see a figure looming on the roof of one of the buildings in Boston…but no one seems to know who he is or what he was doing up there.

One Twitter user even called the figure “the spookiest thing I have ever seen.”

While the mysterious figure could be entirely unrelated to the bombing attack, the Boston division of the FBI has asked anyone with any information or images that might contain any clues to call them at 1-800-CALL-FBI.

The figure is even causing the conspiracy theorists to go nuts.  They claim that the U.S. perpetrated the attack so that President Obama could declare Marshal Law and come after our guns.
