John F. Kennedy autopsy

General Godfrey McHugh ordered Kennedy's body to be illegally transported to Walter Reed Army Medical Center before the choice of hospital was given to Jacqueline Kennedy.

Kennedy's aides disagreed as to where the autopsy should be conducted. Kennedy's personal physician, Rear Admiral George Burkley pushed for Bethesda Naval Hospital.[8] However, Major General Ted Clifton instructed Surgeon General Leonard D. Heaton that it would be conducted at Walter Reed Army Medical Center.[8][9] General Godfrey McHugh ordered an ambulance to transport Kennedy's body to Walter Reed. When informed that it was illegal to do so in D.C. without a coroner's permission, McHugh offered to pay the fine.[10] Burkley then consulted with Jacqueline, who was initially reluctant to have an autopsy.[10] She selected Bethesda Naval Hospital as President Kennedy had been a naval officer during World War II.[10][11] She choose Secret Service Agent William Greer—who she felt sorry for as he faulted himself for not saving the president—to drive Kennedy's casket to Bethesda.[10] As the body was transported from Andrews Air Force Base to Bethesda, crowds of mourners lined the roads.[12]

Navy Surgeon General Edward C. Kenney ordered two naval medical doctors, Commander James Humes and Commander J. Thornton Boswell, to conduct the autopsy.[13] Humes was selected as lead surgeon. Boswell called the decision to conduct the autopsy at Bethesda "stupid" and argued that it should instead be held at the specialized Armed Forces Institute of Pathology (AFIP) just five miles away. Although both had conducted autopsies, neither were trained or certified in forensic pathology.[14][note 2]

At 7:35 pm EST on November 22, Humes and Boswell removed Kennedy's body from his bronze casket and began the autopsy.[16] Around two dozen people, including military officers, were in attendance.[17][note 3] Admiral Burkley urged the doctors to expedite the autopsy: "all we need is the bullet". Drs. Humes and Boswell, however, argued for a thorough and complete autopsy but temporarily submitted.[23] Medical personnel took photographs—both black and white and color—and X-rays of his head.[23] The X-rays revealed around 40 small bullet fragments along the bullet's trajectory through Kennedy's head, with two large enough to be of interest to investigators. Drs. Humes and Boswell then contacted wound ballistics expert Lieutenant Colonel Pierre Finck of AFIP for assistance.[24] However, they grew tired of waiting and removed the two fragments.[25] They also extracted Kennedy's entire brain and placed it into formaldehyde for later study. Finck arrived soon thereafter and examined the head wound with Boswell and Humes.[26]

The missing bullet—found on a used stretcher at Parkland Memorial Hospital—became the subject of the Warren Commission's single-bullet theory, often derided as the "magic-bullet theory" by conspiracy theorists.

Kennedy's body was then turned onto its side to examine the other wound. The three identified an entry point in Kennedy's back but were unable to find the corresponding exit wound or the bullet upon initial probing. Finck argued for a complete radiological survey of the body, and Humes suggested they conduct a complete autopsy. This angered Burkley, who argued that Jacqueline only wanted a limited autopsy. Admiral Calvin Galloway—the commanding officer of the US Naval Medical Center—overruled Burkley and ordered the doctors to carry out an entire autopsy.[27][note 4] However, after further examination and the full-body X-rays, no bullet or major fragment was recovered from Kennedy's body.[29] The physicians were puzzled, and observers suggested various hypotheses—the projectile was a soft-point bullet, made of plastic or ice—until an FBI agent informed the physicians that a bullet had just been found at Parkland.[30]

After midnight, three skull fragments discovered by the Secret Service were brought to the pathologists.[31] They noted the largest fragment had what appeared to be an exit wound, confirmed when X-rays found metal fragments.[32] After completing the autopsy after midnight, Humes informed the waiting FBI agents that Kennedy had been hit by two bullets from behind, to the back and to the head. He concluded that the latter bullet had been fatal, and that the former had "worked its way out of the body during cardiac massage at Parkland".[33]

Burkley signed a death certificate on November 23 and noted that the cause of death was a gunshot wound to the skull.[34][35] He described the fatal head wound as something "shattering in type causing a fragmentation of the skull and evulsion of three particles of the skull at time of the impact, with resulting maceration of the right hemisphere of the brain."[35] He also noted "a second wound occurred in the posterior back at about the level of the third thoracic vertebra".[35] A second certificate of death, signed on December 6 by Theron Ward, a Justice of the Peace in Dallas County, stated that Kennedy died "as a result of two gunshot wounds (1) near the center of the body and just above the right shoulder, and (2) 1 inch to the right center of the back of the head."[36]

The first bullet struck Kennedy in his upper back and exited below his neck. The opening in the President's neck was from a tracheotomy. However, the bullet exit wound was located there.

1. The Bethesda autopsy physicians attempted to probe the bullet hole in the base of Kennedy's neck above the scapula, but failed as it had passed through neck strap muscle. They did not perform a full dissection or persist in tracking, as throughout the autopsy they were unaware of the exit wound at the front of the throat. Emergency room physicians had obscured it while performing the tracheotomy.
2. At Bethesda, the autopsy report of the president, Warren Exhibit CE 387,[37] described the back wound as being oval-shaped, 6 by 4 millimeters (0.24 in × 0.16 in), and located "above the upper border of the scapula" (shoulder blade) at a location 14 centimeters (5.5 in) from the tip of the right acromion process, and 14 centimeters (5.5 in) below the right mastoid process (the bony prominence behind the ear).
3. The concluding page of the Bethesda autopsy report[37] states that "[t]he other missile [the bullet to the back] entered the right superior posterior thorax above the scapula, and traversed the soft tissues of the supra-scapular and the supra-clavicular portions of the base of the right side of the neck."
4. The report also said that there was contusion (i.e., a bruise) of the apex (top tip) of the right lung in the region where it rises above the clavicle, and noted that although the apex of the right lung and the parietal pleural membrane over it had been bruised, they were not penetrated. This indicated passage of a missile close to them, but above them. The report pointed out that the thoracic cavity was not penetrated.
5. This bullet produced contusions both of the right apical parietal pleura and of the apical portion of the right upper lobe of the lung. The bullet contused the strap muscles of the right side of the neck, damaged the trachea, and exited through the anterior surface of the neck.
6. The single bullet theory of the Warren Commission Report places a bullet wound at the sixth cervical vertebra (C6) of the vertebral column, which is consistent with 5.5 inches (14 cm) below the ear. The Warren Report itself does not conclude bullet entry at the sixth cervical vertebra, but this conclusion was made in a 1979 report on the assassination by the HSCA, which noted a defect in the C6 vertebra in the Bethesda X-rays, which the Bethesda autopsy physicians had missed and did not note. The X-rays were taken by US Navy Medical Corps Commander John H. Ebersole.

Even without any of this information, the original Bethesda autopsy report, included in the Warren Commission report, concluded that this bullet had passed entirely through the President's neck, from a level over the top of the scapula and lung (and the parietal pleura over the top of the lung) and through the lower throat.

At left, a diagram made for the House Committee showing the trajectory of the bullet through President Kennedy's skull. The rear wound corresponds with the small entry wound above. The skull fragments are shown exploded for illustrative purposes; most stayed attached to the skull by skin flaps, which are being pulled forward by the gloved hand in the drawing made from an autopsy illustration and visible in the colored photograph on the right.

1. The gunshot wound to the back of the president's head was described by the Bethesda autopsy as a laceration measuring 15 by 6 millimetres (0.59 in × 0.24 in), situated to the right and slightly above the external occipital protuberance. In the underlying bone is a corresponding wound through the skull showing beveling (a cone-shaped widening) of the margins of the bone as viewed from the inside of the skull.[38]
2. The large and irregularly-shaped wound in the right side of the head (chiefly to the parietal bone, but also involving the temporal and occipital bone) is described as being about 13 centimetres (5.1 in) wide at the largest diameter.[38]
3. Three skull bone fragments were received as separate specimens, roughly corresponding to the dimensions of the large defect. In the largest of the fragments is a portion of the perimeter of a roughly circular wound presumably of exit, exhibiting beveling of the exterior of the bone, and measuring about 2.5 to 3.0 centimetres (0.98 to 1.18 in). X-rays revealed minute particles of metal in the bone at this margin.[38]
4. Minute fragments of the projectile were found by X-ray along a path from the rear wound to the parietal area defect.[39]

The panel organized by Attorney General Ramsey Clark (pictured with President Lyndon B. Johnson in 1968) found that two bullets struck Kennedy from behind.

In 1968, U.S. Attorney General Ramsey Clark appointed a panel of four medical experts to examine photographs and X-rays from the autopsy.[40] The panel confirmed findings that the Warren Commission had published: the President was shot from behind and was hit by only two bullets. The summary by the panel stated: "Examination of the clothing and of the photographs and X-rays taken at [the] autopsy reveal that President Kennedy was struck by two bullets fired from above and behind him, one of which traversed the base of the neck on the right side without striking bone and the other of which entered the skull from behind and exploded its right side."[41]

The five-member Rockefeller Commission, which included three pathologists, a radiologist, and a wound ballistics expert, did not address the back and throat wounds, writing in its report that "[t]he investigation was limited to determining whether there was any credible evidence pointing to CIA involvement in the assassination of President Kennedy," and that "[t]he witnesses who [had] presented evidence believed sufficient to implicate the CIA in the assassination of President Kennedy placed [too] much stress upon the movements of the President's body associated with the head wound that killed the President."

The Commission examined the Zapruder, Muchmore, and Nix films; the 1963 autopsy report, the autopsy photographs and X-rays, President Kennedy's clothing and back brace, the bullet and bullet fragments recovered, the 1968 Clark Panel report, and other materials. The five panel members came to the unanimous conclusion that President Kennedy had been hit by only two bullets, both of which were fired from the rear, including one that hit the back of the head. Three of the physicians reported that the backward and leftward motion of the President's upper body following the head shot was caused by a "violent straightening and stiffening of the entire body as a result of a seizure-like neuromuscular reaction to major damage inflicted to nerve centers in the brain."

The report added that there was "no evidence to support the claim that President Kennedy was struck by a bullet fired from either the grassy knoll or any other position to his front, right front, or right side … No witness who urged the view [before the Rockefeller Commission] that the Zapruder film and other motion picture films proved that President Kennedy was struck by a bullet fired from his right front was shown to possess any professional or other special qualifications on the subject."[42]

The United States House Select Committee on Assassinations (HSCA) contained a forensic pathology panel—often simply described as the medical panel—that undertook the unique task of reviewing original autopsy photographs and X-rays and interviewed autopsy personnel, as to their authenticity.[44] The Panel and HSCA then went on to make some medical conclusions based on this evidence. The committee's forensic pathology panel included nine members, eight of whom were chief medical examiners in major local jurisdictions in the United States. As a group, they were responsible for over 100,000 autopsies, an accumulation of experience that the committee deemed invaluable in the medical evidence evaluation — including the autopsy X-rays and photographs — to determine the cause of the President's death as well as the nature and locations of his wounds.

The HSCA forensic pathology panel concluded that the autopsy had "extensive failings" and that the pathologists made multiple procedural errors, as following:[45]

• Failing to confer with the Parkland doctors prior to the autopsy
• Failing to examine clothing, which could have indicated trajectories
• Failing to determine the exact exit point of the head bullet
• Failing to dissect the back and neck
• Failing to determine the angles of gunshot injuries relative to body axis
• Failing to take proper and sufficient photographs
• Failing to properly examine the brain

A meeting of the House Select Committee on Assassinations

The forensic panel concluded that the three pathologists were not qualified to conduct a forensic autopsy. Panel member Milton Helpern, Chief Medical Examiner for New York City, went so far as to say that selecting Humes (who had only taken a single course on forensic pathology) to lead the autopsy was "like sending a seven-year-old boy who has taken three lessons on the violin over to the New York Philharmonic and expecting him to perform a Tchaikovsky symphony".[46]

The committee also employed experts to authenticate the autopsy materials. Neither the Clark Panel nor the Rockefeller Commission undertook to determine if the X-rays and photographs were, in fact, authentic. Considering the numerous issues that had arisen over the years with respect to autopsy X-rays and photographs, the committee believed that authentication was a crucial step in the investigation. The authentication of the autopsy X-rays and photographs was accomplished by the committee assisting its photographic evidence panel as well as forensic dentists, forensic anthropologists, and radiologists working for the committee. Two questions were put to these experts:

1. Could the photographs and X-rays stored in the National Archives be positively identified as being of President Kennedy?
2. Was there any evidence that any of these photographs or X-rays had been altered in any manner?

To determine if the photographs of the autopsy subject were actually of the President, forensic anthropologists compared the autopsy photographs with ante-mortem pictures of him. This comparison was done based on both metric and morphological features. The metric analysis relied on various facial measurements taken from the photographs. The morphological analysis dealt with the consistency of physical features, particularly those that could be considered distinctive, such as the shape of the nose and patterns of facial lines (i.e. once unique characteristics were identified, posterior and anterior autopsy photographs were compared to verify that they depicted the same person).

The anthropologists studied the autopsy X-rays together with premortem X-rays of the President. A sufficient number of unique anatomic characteristics were present in X-rays taken before and after the President's death to conclude that the autopsy X-rays were of President Kennedy. This conclusion was consistent with the findings of a forensic dentist employed by the committee. Since many of the X-rays taken during the course of the autopsy included Kennedy's teeth, it was possible to determine, using his dental records, that the X-rays were of the President.

As soon as the forensic dentist and anthropologists had determined that the autopsy photographs and X-rays were of the President, photographic scientists and radiologists examined the original autopsy photographs, negatives, transparencies, and X-rays for signs of alteration. They concluded that there was no evidence of the photographic or radiographic materials having been altered, so the committee determined that the autopsy X-rays and photographs were a valid basis for the conclusions of the committee's forensic pathology panel.

While the examination of the autopsy X-rays and photographs was mainly based on its analysis, the forensic pathology panel also had access to all relevant witness testimony. Furthermore, all tests and evidence analyses requested by the panel were performed. It was only after considering all of this evidence that the panel reached its conclusions.

The pathology panel concluded that President Kennedy was struck by only two bullets, each of which had been shot from behind. The panel also concluded that the President was struck by "one bullet that entered in the upper right of the back and exited from the front of [his] throat, and one bullet that entered in the right rear of [his] head near the cowlick area and exited from the right side of the head, toward the front" saying that "this second bullet caused a massive wound to the President's head upon exit." The panel concluded that there was no medical evidence that the President was struck by a bullet entering the front of the head; and the possibility of such a bullet having struck him and yet left no physical evidence was extremely remote.

Because this conclusion appeared to be inconsistent with the backward motion of the President's head in the Zapruder film, the committee consulted a wound ballistics expert to determine what relationship, if any, exists between the direction from which a bullet strikes the head and the subsequent head movement. The expert concluded that nerve damage caused by a bullet entering the President's head could have caused his back muscles to tighten which, in turn, could have forced his head to move toward the rear. He demonstrated the phenomenon in a filmed experiment involving the shootings of goats. Therefore, the committee determined that the rearward movement of the President's head would not have been fundamentally inconsistent with a bullet striking from the rear.[47]

The HSCA also voiced certain criticisms of the original Bethesda autopsy and handling of evidence from it. These included:

1. the "entrance head wound location was incorrectly described."
2. The autopsy report was "incomplete", prepared without reference to the photographs, and was "inaccurate" in a number of areas, including the entry in Kennedy's back.
3. The "entrance and exit wounds on the back and front neck were not localized with reference to fixed body landmarks and to each other".

The House Select Committee on Assassinations testimony of Cyril Wecht, the one dissenting member of the autopsy panel is recorded below. He is a vocal critic of the single-bullet theory, often derided as the "magic-bullet theory" by conspiracy theorists. The bullet's trajectory is pictured top per the Warren Commission, and bottom per detractors.

The HSCA's major medical-forensic conclusion was that "President Kennedy was struck by two rifle shots fired from behind him."[48] The committee found acoustic evidence of a second shooter, but concluded that this shooter did not contribute to the president's wounds, and therefore was irrelevant to the autopsy results. However, Cyril Wecht—described by Bugliosi as the most "prominent medical critic of the Warren Commission"—was a frequent dissenter on the nine-member of the HSCA's medical panel and rejected the Warren Commission's single-bullet theory. He did concur with the other pathologists that Kennedy was hit in the head and upper back and that both shots came from behind.[49] Wecht has, however, argued that Kennedy may have been hit by two other shots. He has argued that the throat wound is more indicative of an entry wound than an exit wound. Wecht has also suggested that Kennedy's head may have been hit by two nearly simultaneous shots, one from the rear and one from the front.[50]

It is helpful on times and personnel, but the agents were non-medically trained people who did not completely understand what they were seeing in the actual autopsy wounds. Moreover, the early report preserves genuine medical doctor confusion present actually during the autopsy, caused by apparent lack of an exit wound, which was cleared up later in the official report after new and more complete information became available.
