David Green snapped an iPhone photo shortly after the Boston Marathon bombings Monday.
When the FBI released images of two suspects Thursday, Green, with the help of a friend, noticed something towards the lower portion of his own image. It was Suspect Two, in a white cap.
Greens photo shows the suspect at a side angle leaving the bombing scene.
I spoke to the FBI and it may be the best photo they have, the Jacksonville native posted on his Facebook account.
In an interview late Thursday with The New York Times, Green confirmed that the picture was genuine, and that the FBI had requested a copy.
I have spoken to several agents, Green said, and they have got the photos, they are picking up material from me, and I dont think theres any doubt.
Agents had told him, he relayed to The New York Times, that his picture was the best they had, because it was taken from a better camera than the others that were posted.
