As the motorcade approached the intersection of Houston and Elm Streets, there was general gratification in the Presidential party about the enthusiastic reception. Evaluating the political overtones, Kenneth O’Donnell was especially pleased because it convinced him that the average Dallas resident was like other American citizens in respecting and admiring the President.[C2-139] Mrs. Connally, elated by the reception, turned to President Kennedy and said, “Mr. President, you can’t say Dallas doesn’t love you.” The President replied, “That is very obvious.”[C2-140]
THE ASSASSINATION
At 12:30 p.m., c.s.t., as the President’s open limousine proceeded at approximately 11 miles per hour along Elm Street toward the Triple Underpass, shots fired from a rifle mortally wounded President Kennedy and seriously injured Governor Connally. One bullet passed through the President’s neck; a subsequent bullet, which was lethal, shattered the right side of his skull. Governor Connally sustained bullet wounds in his back, the right side of his chest, right wrist, and left thigh.
The Time
The exact time of the assassination was fixed by the testimony of four witnesses. Special Agent Rufus W. Youngblood observed that the large electric sign clock atop the Texas School Book Depository Building showed the numerals “12:30” as the Vice-Presidential automobile proceeded north on Houston Street, a few seconds before the shots were fired.[C2-141] Just prior to the shooting, David F. Powers, riding in the Secret Service followup car, remarked to Kenneth O’Donnell that it was 12:30 p.m., the time they were due at the Trade Mart.[C2-142] Seconds after the shooting, Roy Kellerman, riding in the front seat of the Presidential limousine, looked at his watch and said “12:30” to the driver, Special Agent Greer.[C2-143] The Dallas police radio log reflects that Chief of Police Curry reported the shooting of the President and issued his initial orders at 12:30 p.m.[C2-144]
Speed of the Limousine
William Greer, operator of the Presidential limousine, estimated the car’s speed at the time of the first shot as 12 to 15 miles per hour.[C2-145] Other witnesses in the motorcade estimated the speed of the President’s limousine from 7 to 22 miles per hour.[C2-146] A more precise determination has been made from motion pictures taken on the scene by an amateur photographer, Abraham Zapruder. Based on these films, the speed of the President’s automobile is computed at an average speed of 11.2 miles per hour. The car maintained this average speed over a distance of approximately 136 feet immediately preceding the shot which struck the President in the head. While the car traveled this distance, the Zapruder camera ran 152 frames. Since the camera operates at a speed of 18.3 frames per second, it was calculated that the car required 8.3 seconds to cover the 136 feet. This represents a speed of 11.2 miles per hour.[C2-147]
In the Presidential Limousine
Mrs. John F. Kennedy, on the left of the rear seat of the limousine, looked toward her left and waved to the crowds along the route. Soon after the motorcade turned onto Elm Street, she heard a sound similar to a motorcycle noise and a cry from Governor Connally, which caused her to look to her right. On turning she saw a quizzical look on her husband’s face as he raised his left hand to his throat. Mrs. Kennedy then heard a second shot and saw the President’s skull torn open under the impact of the bullet. As she cradled her mortally wounded husband, Mrs. Kennedy cried, “Oh, my God, they have shot my husband. I love you, Jack.”[C2-148]
Governor Connally testified that he recognized the first noise as a rifle shot and the thought immediately crossed his mind that it was an assassination attempt. From his position in the right jump seat immediately in front of the President, he instinctively turned to his right because the shot appeared to come from over his right shoulder. Unable to see the President as he turned to the right, the Governor started to look back over his left shoulder, but he never completed the turn because he felt something strike him in the back.[C2-149] In his testimony before the Commission, Governor Connally was certain that he was hit by the second shot, which he stated he did not hear.[C2-150]
