Hours after the FBI released photos of the Boston Marathon bombing suspects, a number of theories about the suspects and photos claiming to depict them began popping up online, and now one photo in particular has proven legitimate.
The photograph shows the second bombing suspect, who was wearing a white hat on the day of the marathon, turning a corner after one of the two explosions.
David Green, who took the photograph with his iPhone, posted it on Facebook earlier in the week. A friend of his then posted the photo to the running website LetsRun.com on Thursday after noticing a likeness between a man in the photo and one of the FBI's suspects in the bombings.

The photo found its way onto Reddit.com, where it quickly went viral - though some users questioned its authenticity.
Around 7 p.m. Thursday, bolstered by the growing popularity of his photo online, Green contacted the FBI regarding the image.
Several hours later, around midnight, Green told CNN's Piers Morgan and The New York Times that they believed the photo showed the second suspect.

Green, from Jacksonville, Florida, said he never would have noticed the man in the white hat without the astuteness of his friends on Facebook and other web users.
He had alerted the FBI to the photo earlier in the week, but he originally pointed out another man in the image whom he believed looked suspicious.
