Single Bullet Wound Ballistics Evidence
Wound ballistics specialists from Edgewood Arsenal evaluated medical evidence of President Kennedy and Governor Connally’s wounds alongside controlled ballistics tests to assess the single-bullet theory. Drs. Arthur J. Dziemian (Army Wound Ballistics Branch chief with 17 years of specialization) and Olivier concluded it was probable a single bullet passed through the President’s neck and caused all of the Governor’s wounds, citing the Governor’s wrist wound severity (indicating the bullet lost velocity after passing through the President’s neck and yawing in flight) and the large back wound consistent with a yawing bullet. Dr. Frederick W. Light, Jr. found anatomical evidence insufficient for a firm independent opinion but agreed the single-bullet trajectory was probable based on the two men’s positions in the limousine.
The Subsequent Bullet That Hit
After the first shot struck President Kennedy’s neck, a second shot penetrated the back of his head and exited through the upper right skull, as captured in the Zapruder, Nix, and Muchmore films. Analysis of these films, combined with plat mapping of cameramen positions, precisely located the President at the time of the head shot: 230.8 feet from the west curbline intersection of Houston and Elm Streets, 265.3 feet from the sixth-floor rifle window, at a 15°21’ angle of declination. The impact was visible as an explosion of brain tissue from the right side of the President’s head in the footage.
