Direct Answer: The Entry and Exit Points
President John F. Kennedy was shot in the head by a single bullet that entered the rear of his skull and exited from the front, causing massive trauma. This conclusion is drawn from the official autopsy, the forensic pathology report, the Zapruder film frame-by-frame analysis, and the subsequent reinvestigations. Below, we explain the precise location of entry and exit, describe how this injury affected Kennedy physically, and detail how investigators reached this determination using medical, photographic, and testimonial evidence. This overview reflects an evidence-first, verifiable record intended for long-term reference.
Primary Source Records
The authoritative record comes from the Federal Bureau of Investigation and the Federal Emergency Medical Services that treated Kennedy at Parkland Memorial Hospital. The Bethesda autopsy, conducted under the direction of the U.S. Navy and Armed Forces medical personnel, further established the wound track. The Warren Commission combined these documents with ballistics tests on the recovered bullet and photography to form the central factual account. Subsequent reinvestigations, including those by the House Select Committee on Assassinations, reviewed this body of evidence without overturning the core medical findings regarding the head shot.
The Autopsy Protocol and Imaging
The Kennedy autopsy followed then-standard military procedure: external examination, internal organ inspection, and radiography. Medical staff documented wounds to the head, neck, and torso with photographs and diagrams. Radiographs helped locate fragments and confirm the trajectory, supporting the narrative that a single projectile traveled from the rear forward. Later analyses of these materials by forensic experts have underscored the consistency of the entry and exit descriptions across multiple professional reviews.
Key Evidence in Brief
| Attribute | Verified Detail | Source Type |
|---|---|---|
| Entry Location | Rear cranial vault, near the external occipital protuberance and superior nuchal line | Autopsy diagrams and report |
| Exit Location | Anterior cranial vault, at the right temple area | Autopsy diagrams, official pathology narrative |
| Official Time of Arrival at Parkland | 1:00P.M. Central Time, November 22, 1963 | Hospital logs and contemporaneous notes |
| Medical Consensus on Cause of Death | Cerebral and massive brain damage from gunshot wounds to the head and neck | Conspiracy of medical examiners and Bethesda autopsy team |
| Recovered Bullet Condition | d>Fragmented, with portions reassembled to match rifling marks | FBI and Army ordnance tests |
How the Injury Occurred in Sequence
As the motorcade passed the Texas School Book Depository, the bullet struck the back of the head and traveled through the cranial cavity, exiting near the right temple. This violent disruption of brain tissue led to immediate neurological failure and catastrophic blood loss. The Zapruder film, frame-by-frame analysis, captures the reaction consistent with a rear-to-front wound, showing Kennedy’s head snapping backward and then forward under acceleration forces. This motion, combined with the physical evidence on the stretcher and the transfer of blood and tissue, corroborates the wound trajectory and refutes alternative paths that would contradict forensic measurements.
Alternative Trajectory Theories and Forensic Review
Over the years, various hypotheses have suggested different entry points or multiple shooters, often citing inconsistencies in witness descriptions or Zapruder film interpretation. Forensic experts have repeatedly tested these theories using skull replicas, ballistic gelatin, and comparison with the original autopsy photographs. Those reviews generally find that the most parsimonious explanation remains a single bullet entering the rear and exiting the front, even if some details remain debated. Material evidence such as the shirt fragments, the stretcher blood patterns, and the bullet fragments all align with this model when evaluated together.
Enduring Significance and Reference Points
Understanding precisely where JFK was shot in the head matters not only for historical accuracy but also for ongoing assessments of ballistics, trauma medicine, and public trust in official investigations. The documented entry and exit locations, supported by imaging and multiple expert analyses, form a durable basis for discussion. Continuing research incorporates modern imaging and biomechanical simulations, allowing each generation to reassess conclusions with improved methods while respecting the core evidentiary record. This explanation remains tied to verified sources and avoids speculative claims that cannot withstand technical review.
Summary of Key Details
- Entry: Rear of the skull, near the external occipital protuberance and superior nuchal line
- Exit: Anterior right temple area
- Medical conclusion: Massive cerebral injury from a gunshot wound traversing the cranial cavity
- Key evidence: Autopsy diagrams and narrative, Bethesda and Dallas hospital records, the Zapruder film, ballistics tests
- Timeline critical point: Head shot occurred at approximately 12:30P.M. as the motorcade turned from Houston Street onto Elm Street in Dealey Plaza
Relevant Historical Sources and Materials
Primary materials include the National Archives release of documents, the Warren Commission volumes, the House Select Committee on Assassinations report, and the official autopsy photographs and radiographs subjected to peer review. These datasets provide the foundation for any reliable account of the head wound. Forensic pathologists and historians continue to reference these documents when explaining the injury and its effects, ensuring that public understanding remains grounded in verifiable observation rather than speculation. The durability of this material supports its use in long-term educational and reference contexts.
