The autopsy also disclosed a wound near the base of the back of President Kennedy’s neck slightly to the right of his spine. The doctors traced the course of the bullet through the body and, as information was received from Parkland Hospital, concluded that the bullet had emerged from the front portion of the President’s neck that had been cut away by the tracheotomy at Parkland.[C2-284] The nature and characteristics of this neck wound and the two head wounds are discussed fully in the next chapter. After the autopsy was concluded at approximately 11 p.m., the President’s body was prepared for burial. This was finished at approximately 4 a.m.[C2-285] Shortly thereafter, the President’s wife, family and aides left Bethesda Naval Hospital.[C2-286] The President’s body was taken to the East Room of the White House where it was placed under ceremonial military guard. CHAPTER III The Shots From the Texas School Book Depository In this chapter the Commission analyzes the evidence and sets forth its conclusions concerning the source, effect, number and timing of the shots that killed President Kennedy and wounded Governor Connally. In that connection the Commission has evaluated (1) the testimony of eyewitnesses present at the scene of the assassination; (2) the damage to the Presidential limousine; (3) the examination by qualified experts of the rifle and cartridge cases found on the sixth floor of the Texas School Book Depository and the bullet fragments found in the Presidential limousine and at Parkland Hospital; (4) the wounds suffered by President Kennedy and Governor Connally; (5) wound ballistics tests; (6) the examination by qualified experts of the clothing worn by President Kennedy and Governor Connally; and (7) motion-picture films and still photographs taken at the time of the assassination. THE WITNESSES As reflected in the previous chapter, passengers in the first few cars of the motorcade had the impression that the shots came from the rear and from the right, the general direction of the Texas School Book Depository Building, although none of these passengers saw anyone fire the shots. Some spectators at Houston and Elm Streets, however, did see a rifle being fired in the direction of the President’s car from the easternmost window of the sixth floor on the south side of the building. Other witnesses saw a rifle in this window immediately after the assassination. Three employees of the Depository, observing the parade from the fifth floor, heard the shots fired from the floor immediately above them. No credible evidence suggests that the shots were fired from the railroad bridge over the Triple Underpass, the nearby railroad yards or any place other than the Texas School Book Depository Building.
