Black and white undated photograph of FBI agents demonstrating how President Kennedy and Governor Connally may have been struck by a single bullet. The car in the photograph was the Secret Service vehicle following directly behind President Kennedy on November 22, 1963. The two agents are sitting in approximately the same positions as President Kennedy and Governor Connally. Note the chalk marks on their backs showing the bullet entrance locations on both men. The third man, Warren Commission staff member Arlen Specter, stands beside the car with a metal rod to show the possible trajectory of the bullet through the two men based on measurements made during the May 1964 reenactment in Dallas.
This copy of a photograph was part of FBI Special Agent Lyndal Shaneyfelt's Kennedy assassination file; Shaneyfelt assisted in the FBI investigations of the assassination conducted on behalf of the Warren Commission in 1964.
