CONCORD, N.H. – The infamous photograph of Lee Harvey Oswald holding a rifle in his backyard would have been nearly impossible to fake, according to a new analysis by a Dartmouth College professor.

Oswald, who was shot to death days after being charged with the 1963 assassination of President John F. Kennedy, claimed the photo of him holding a rifle in one hand and Marxist newspapers in the other had been doctored. Over the years, many others have pointed out what appear to be inconsistent lighting and shadows.

But Hany Farid, director of the Neukom Institute for Computational Science at Dartmouth, said the shadows are exactly where they should be.
