Roy Schaeffer served in the Marine Corps during the Eisenhower and Kennedy administrations (1960-1962). After graduating from Aviation Electronics School in San Diego , he was assigned the same job Lee Harvey Oswald had previously done at El Toro AFB.
He was working for the Dayton Daily News (DDN) the weekend of the Kennedy assassination. On the morning after JFK was assassinated, Schaeffer was asked to retrieve two wire photos for the Sunday Edition of the DDN. Seeing those photos would one day start him on a journey investigating the Kennedy assassination, though before that time he had no reason to question the Warren Commission's findings.
Fourteen years later, Schaeffer saw the wire photos as they were published on that Sunday and knew both photos were altered before the paper went to press. After finding more possible film alterations, studying the Warren Commission's report and recognizing two Marines names in official reports, Schaeffer knew he had some insights, that by pure chance, no one else had.
In 1986 he wrote Jim Garrison about an extra 8mm Zapruder film made during the Clay Shaw trial. About a year later he received a copy from Fay Turner, a detective who questioned Oswald shortly after his arrest. By studying the Zapruder film in great detail, Schaeffer was able to make a composite blink-rate chart by plotting the emergency blinking lights on the front grill of the Presidential limousine frame by frame. By examining the blinking-light pattern, he concluded that Zapruder's camera ran at a faster speed than 18 frames per second, thus providing film-tampering evidence. Schaeffer testified before the Assassination Records Review Board in Dallas in 1994.
Schaeffer co-authored a chapter entitled, "The Case for Zapruder Film Tampering" in Assassination Science, Experts Speak Out about the Death of JFK with Mike Pincher, Esq. and edited by James H. Fetzer. Schaeffer has been researching the Kennedy assassination for more than 30 years and is now placing his research material at the Poage Library.
