Kennedy conspiracy theorists appear to have one less bullet in their arsenal. Hany Farid, a computer science professor and expert in digital forensics at Dartmouth College, spent two months evaluating a photograph of John F. Kennedy shooter Lee Harvey Oswald.

“You can’t really authenticate a photo in all honesty,” Farid said of the image, which shows Oswald holding a Marxist newspaper and a rifle. “But I can say pretty definitively that the things that people thought made the photo a fake, well, those people are wrong. And it doesn’t make them stupid. I was wrong too. But that photo is not the proof they think it is.”

It’s long been the contention of conspiracy theorists that photos of Oswald were doctored as part of an elaborate cover-up after the President’s Nov. 22, 1963, assassination.

He used a computer program Facegen, to build a virtual 3D model of Oswald’s head. Once that was completed, he added in the background features of the photo. Through a series of computations, he figured out where the camera had to be, the trajectory of the sun and where Oswald was in relation to the camera.

Farid said given the technology available 46 years ago, there is no way someone would have been able to get the internal and external elements of the photo just right in order to fabricate not only the one photo, but two others in the series.
