Lee Harvey Oswald could not have acted alone in assassinating President John F Kennedy, according to a new study by Italian weapons experts of the type of rifle Oswald used in the shootings.
In fresh tests of the Mannlicher-Carcano bolt-action weapon, supervised by the Italian army, it was found to be impossible for even an accomplished marksman to fire the shots quickly enough.
The findings will fuel continuing theories that Oswald was part of a larger conspiracy to murder the 35th American president on 22 November 1963.
The official Warren Commission inquiry into the shooting concluded the following year that Oswald was a lone gunman who fired three shots with a Carcano M91/38 bolt-action rifle in 8.3 seconds.
