Dave did a lot of calculations on this very subject some time back. He is a physics person. He concluded that it would take a greater force than Patsy was capable of, swinging just about anything, to inflict this blow. And she is right about falling. JB would have had to fall about 15 feet landing on her head to cause that type of wound which, of course, would have broken her neck as well.

This led to Dave's famous coconut experiments, as their shell approximate the strength of a skull. He was able to punch a small hole in one, using the butt end of a mag lite flashlight, and a lot of force.

All this is in the archives somewhere but it proves to me that the head trauma was no accident. Whoever hit her intended to kill her. I think to guarantee that she was dead, or would die, given that some persons survive strangulation, albeit in a vegetative state.

And I have to respectfully disagree with Mikie about the size of the weapon in relation to the size of the hemorrage/bruising.
