the Governor’s back would be explained by a bullet which was yawing, although that type of wound might also be accounted for by a tangential striking.[C3-322] Dr. Frederick W. Light, Jr., the third of the wound ballistics experts, who has been engaged in that specialty at Edgewood Arsenal since 1951, testified that the anatomical findings were insufficient for him to formulate a firm opinion as to whether the same bullet did or did not pass through the President’s neck first before inflicting all the wounds on Governor Connally.[C3-323] Based on the other circumstances, such as the relative positions of the President and the Governor in the automobile, Dr. Light concluded that it was probable that the same bullet traversed the President’s neck and inflicted all the wounds on Governor Connally.[C3-324] The Subsequent Bullet That Hit After a bullet penetrated President Kennedy’s neck, a subsequent shot entered the back of his head and exited through the upper right portion of his skull. The Zapruder, Nix and Muchmore films show the instant in the sequence when that bullet struck. (See Commission Exhibit No. 902, p. 108.) That impact was evident from the explosion of the President’s brain tissues from the right side of his head. The immediately preceding frame from the Zapruder film shows the President slumped to his left, clutching at his throat, with his chin close to his chest and his head tilted forward at an angle.[C3-325] Based upon information provided by the doctors who conducted the autopsy, an artist’s drawing depicted the path of the bullet through the President’s head, with his head being in the same approximate position.[C3-326]
