Key FBI Photo Of Dzhokhar Shows Evidence Of Photoshop By Ralph Lopez May 29, 2013 The photograph released by the FBI alleging to show Boston bombing suspect Dzohkahr Tsarnaev fleeing the scene without his backpack shows clear evidence of being a composite image made with software such as Photoshop. This reporter went to the scene of the photograph and took pictures for comparison purposes, shown below. The image is touted as evidence that the younger Tsarnaev brother arrived with a backpack but left without it, therefore possibly planting one of the bombs. In the image, a different color and pattern of brickwork can be seen adjacent to Dzhokhar's head, within a rectangle similar to what would be visible if the image were cut and pasted from a different source. The brickwork inside the rectangle also appears to be more sharply in focus than the brick around it. The difference in brickwork can be seen using a free add-on to the Firefox web browser. By using the "Image Zoom" add-on , and zooming in to the original full-size image, investigators can reproduce the resolution and features in the images below. The full-size image is 1600 x 1200 pixels. The photograph was released to the media by the FBI to assist in the identification and capture of the suspect. This was after a runner in the Marathon posted a wide-angle photo of the scene immediately after the explosions in LetsRun.com. The photograph then went viral across the Internet. The witness said that he contacted the FBI when he realized that a man in the background was wearing a white hat similar to the one seen on a suspect in surveillance photos. The photograph was seen as of prime importance because the suspect no longer appeared to be carrying a backpack as before.
