The back wound coincided with holes in Kennedy's clothing measured by the FBI as follows:
5-3/8" down from the coat collar;
5-3/4" down from the shirt collar.
The hole in Kennedy's back did not go deeper than the first joint of the autopsist's finger.
The hole in Kennedy's throat was identified as a wound of entry at Dallas Parkland Memorial.
The attempt to create a through and through shot from the neck through the throat was a failed hoax.
