The results support the official autopsy findings: JFK suffered a gunshot wound caused by the same type of rifle as that owned by Lee Harvey Oswald, fired from the vicinity of the Texas School Book Depository building located behind the motorcade.
"Rather than gloss over this fact, as has been done by most previous authors, including anti-conspiracy authors, I chose to study and model it explicitly," said Dr. Nalli.
He developed a simple one-dimensional gunshot wound dynamics model to explain the movements observed in the film. The model makes explicit calculations of the forward head snap that occurred before JFK's head moved back and to the left after the gunshot.
