I think the crack was from front to rear longitudinally along the upper right side of the skull - above the parietal region of the brain. Right handed - blow from rear. Left handed - blow from front...
Thanks. Without going back to look at the autopsy photos again (which I don't want to do), for whatever reason I see the main site of the fracture as being on the left side of the skull in my mind's eye. But I certainly could be wrong about this point.
