Digital forensic tools have added to the evidence that Lee Harvey Oswald was a lone gunman rather than part of a conspiracy to kill President John F Kennedy. Hany Farid, director of the Neukom Institute for Computational Science at Dartmouth College in New Hampshire in the USA, analysed a famous photo of Oswald that some say must have been doctored, because the shadows under Oswald’s nose and behind his body appear to be caused by different light sources. However, Farid found no sign of tampering when he measured for inconsistencies in the image’s underlying pixels.
He also created a 3D image of Oswald that demonstrated that both shadows could have been made by the sun at the time Oswald’s wife took the photo. Farid says that the image would be hard to fake today, and likely impossible using 1963 technology.
