Dotting the Eye

[Gordon Gray]

There seems to be a lot of evidence for a wound of entrance at the base of the presidents occipital bone. I have often wondered where it exited. I have assumed that the point of exit was obliterated by the entrance of a frangible bullet to the right temple area, fired from the front, but perhaps this black spot/circle/hole? is the exit wound for that shot from the rear. It might be compatible with a trajectory from the Dal Tex building.
