Perhaps you would like to retrieve some of my posts where I have made reference to having problems with adoption.
You ignore all the evidence, supported by research from your 
Ivy league unis, pertaining to ADOPTION, ATTACHMENT and NEUROSCIENCE and want to live in the past discussing the bike, phone calls, and windows like a Neanderthal man. Move on... 30 years have passed since the WHF murders. You are living in the past if you think what applied in 1985/6 is relevant in 2015.
I agree the blood found on the outside of the rifle most likely originated from NB.
You have no idea how the stock broke so please stop claiming that it would have caused damage to the perp's hand as you don't know, no more than I do. And you don't know whether or not EP followed procedures to preserve prints on the weapon, made mistakes, backtracked and wiped thus removing prints.
I do know how it broke because of the way it broke and the way Nevill was being bashed.
The way you bash someone with the butt of the rifle is you hold one hand on the stock where the stock narrows so you can get your hand around it and the other hand will be on the forward grip. That is the way Neville's head was bashed in and the damage done to his arms.
The stock cracked in several places. One crack was inside the stock. The stock is partially hollow and a piece of metal from the gun slides inside the stock. The stock is then screwed to the gun. There is a crack inside where the stock hit the gun because the killer was pushing the butt into Neville's head so you have Neville's head pushing one way and the killer pushing the other so the stock and the rifle are being pressed together. The other crack was where the gun met the stock as well. Both cracks were lateral. The crack near the top actually tore off part of the stock because of where it broke and it broke right on the narrow portion where the killer's hand was. Both cracks in the stock were made as the stock was compressed from being bashed into Neville.
The knob at the left end rests inside the hole that is in the stock.
We went over this in the past. You ignore it because you always ignore all evidence that works against your agenda which is to blame Sheila so you can present your pathetic adoption theories.
You ridiculously suggest she using it like a club. Aside from that making no sense, had someone used it as a club then the breaks would have been up and down in the stock instead of side to side. In fact the stock would have likely broken off if used as a club because the hollow part would have cracked. Moreover, the gun itself would have been damaged if used as a club. The gun itself is actually 2 halves held together by a screw. The barrel could be bent or broken from the receiver if the weapon is used as a bat.
With the screw removed the weapon looks like this:
If I take a bat and I whack the floor with it hard enough to crack the bat which way will the cracks run? The will run width wise.

The crack will run like the I. That is why bats snap in half if you hit them hard enough against something.
What if the head of the bat were hit into the ground instead of the sides of the bat? Then if you manage to crack the bat the cracks will run lengthwise like the dotted line.

The cracks in the stock ran lengthwise and that is because the butt of the weapon was being thrust into Nevill it was not being used like a bat.
