A new study published in the journal Helios corroborates that conclusion. This, he hypothesized, meant the president had been shot from behind.

Shown is the location of cameraman Abraham Zapruder along with the trajectory of the third and fatal shot that killed President Kennedy blue line from the Texas School Book Depository. Plenty of information about the crime has been public for years, and Nalli drew from that well of data to create a model of the physical processes of the gunshot wound.

Nalli soon realized was due to a recoil effect. But he also noted that observers had missed one vital part of the evidence: the forward head snap at the moment of the fatal bullet impact. When analyzed using fundamental classical mechanics, the forward head snap, which is visible in the Zapruder film, provides proof that JFK was shot in the head from behind.

He developed a simple one-dimensional gunshot wound dynamics model to explain the movements observed in the film. To do this, the model uses known parameters from the crime scene, including bullet mass, speed, and diameter, camera shutter frequency and autopsy measurements. This is the first time this aspect of the case has been considered so thoroughly and quantitatively.

Oswald worked located behind the motorcade. Three shots were fired, all from above and behind the target. The first missed. The second, the so-called " magic bullet ," passed through Kennedy and tore into Gov.

Connally, causing all his wounds. Forensics experts disagree, however, arguing that the described path of the second bullet, while improbable, was not impossible and that Kennedy's head snap at the moment of impact suggests a reaction to the first bullet striking him and not the second.
