David Green, 49, of Jacksonville, Fla., had just completed his first Boston Marathon, when he snapped a picture with his iPhone 4S, taken at 2:50, just after the two blasts ripped through the finish line area, killing three people and injuring more than 180 others.
The FBI has not publicly confirmed this photo as Suspect 2, but Green told the Huffington Post that an agent told him, "this is probably the best we have right now."
The man who appears to be Suspect 2 is wearing a white hat with a "3" on the side as seen in the publicly-released photos.
After finishing the marathon, Green said he collected his belongings, and planned to meet with friends near the finish line. Then a pair of bombs exploded.
"The second bomb went off right in front of me," Green said in an interview with The Huffington Post.
One of his first instincts was to get a quick photo. Then he proceeded toward the victims to try to help. That photo can be seen above.
"I soon realized there was nothing I could do but step back," he said. "I couldn't believe what I was seeing [...] I saw people lying in the streets, it was complete mayhem."
It was the only photo he took, he said. Then he started to get some video of the scene.
Green posted the photo to Facebook on Monday.
Little did he know that a man shown in his photo could be one of the men now wanted by the FBI. In the photo, the man seems to be walking away from the scene and he appears to have no backpack.
"This speaks to the power of social media," Green said this evening. "A friend reached out to me and said look at your photo, that's definitely the guy."
Green got in touch with the FBI tonight and said he spoke with multiple agents. He specifically asked if they were OK with him publishing the photo publicly to his Facebook page and he was told it was fine.
The photo started getting attention on Reddit around 8 p.m. ET. A debate emerged whether it was digitally-altered or not.
Green's original post on Facebook, time-stamped Monday before the FBI released any photos, showed that it was not.
