Governor Conally HIT by same bullet! How could this happen?
The Single Bullet Theory!
Introduced by the Warren Commision in its investigation of the assassination of President John F. Kennedy to explain what happened to the bullet which struck Kennedy in the back and exited through his throat. Given the lack of damage to the presidential limousine consistent with it having been struck by a high-velocity bullet and the fact that Texas Governor Connally was wounded and was seated directly in front of the president, the Commission concluded they were likely struck by the same bullet.
Also according to the Warren Report bullet hit JFK in the posterior neck, then without striking any hard object passed through the neck to exit at the front of his throat. It then entered Texas Governor John B. Connally's back at the right arm pit, sliding along his fifth rib, demolishing four inches of the rib before it exited his chest.
Why this makes sense you ask?
Lee Harvey Oswald's Mannlicher-Carcano rifle (Serial Number C2766) was located inside a building which overlooked the assassination site (the Texas School Book Depository) when JFK and JBC were being wounded by gunfire.
A nearly-whole bullet (Warren Commission Exhibit #399) was found inside the hospital where JFK and JBC were taken after the shooting. And CE399 was found in a location within the hospital where President Kennedy was never located prior to the bullet being found by Darrell Tomlinson. (Nor was JFK's stretcher ever in the area of the hospital where Tomlinson discovered the bullet.)
Bullet CE399 was positively fired from Lee Harvey Oswald's rifle.
Bullet CE399, based on the above points in total, HAD to have been inside Governor Connally's body on 11/22/63.
A man who looked like Lee Harvey Oswald was seen firing a rifle at the President's limousine from a southeast corner window on the 6th Floor of the Book Depository Building. No other gunmen were seen firing any weapons in Dealey Plaza on November 22nd.
No bullets (or large bullet fragments) were found in the upper back or neck of John Kennedy's body. And no significant damage was found inside these areas of JFK's body either.
No bullets (or large bullet fragments) were found inside the body of Governor Connally after the shooting. The only bullet, anywhere, that can possibly be connected with Connally's wounds is Bullet CE399.
Given the point in time when both JFK and JBC were first hit by rifle fire (based on the Abraham Zapruder Film), and given the known location of Governor Connally's back (entrance) wound, and also taking into account the individual points made above -- Bullet CE399 had no choice but to have gone through the body of President Kennedy prior to entering the back of John B. Connally.
