Adam quite reasonably asks me why I am sceptical regarding DI Cook's deductions about bullet choreography. To be clear, I am not questioning DI Cook's integrity or competence. I'm simply suggesting that he and his colleagues may have made a mistake - which we all do from time-to-time.
Here's why:
(i). I gather that there was almost no discernible blood trail between the main landing and the kitchen, aside from two isolated spots of blood - respectively, on the main stairway wall and the jamb between the kitchen and the main foyer.
(ii). Poor old Nevill suffered eight gunshot wounds. I am open to correction on this, but my understanding is that of these, only two were non-head shots.
What this evidence is telling me is that Nevill was not shot four times upstairs. I don't doubt that Nevill was shot outside the kitchen. Probably he was shot at least once upstairs - most likely it was on the main landing rather than in the master bedroom (perhaps with the perpetrator firing from the vantage point of the master bedroom while Nevill is on the landlng) - and then he is also shot on the main stairway.
As an aside, my personal view is that the shot to Nevill on the main stairway may have been with Nevill going up the stairs rather than down - if so, the prosecution have problems. But we'll skip that point. For present purposes, let's keep it simple and assume that Nevill is shot on the main stairway with the perpetrator behind him, meaning Nevill is heading down the stairs for the kitchen.
With that preamble, let's get down to the business I want to address: If Nevill was shot upstairs at all, never mind four times, then the following is happening:
(i). He is in pain.
(ii). He is in shock.
(iii). He is bleeding.
(iv). He is touching his own wounds and getting blood on his hands and fingers.
On top of this, if we accept what the Crown say, we think Nevill is shot in the head while he is somewhere upstairs. Perhaps the shot to Nevill's head at this stage is to the jaw/mouth area, which might - might - not incapacitate him, but we need to account for one more head region shot. The problem for the prosecution seems obvious to me. It is of course possible that DI Cook was correct and there was one more head shot at this stage that didn't incapacitate Nevill, but it seems to me rather unlikely.
But let's stick to the Crown's choreography for now. Nevill has been shot upstairs and he is on the main stairway. Then we say Nevill runs to the kitchen. Why? Myself and Adam have been discussing this on another thread. I think I have shown that Nevill could not have made a 999 call, given the evidence available (though, importantly, it does not follow from this that he didn't intend to and try to reach the phone). Following further discussions with Adam, I am also satisfied that it is at least plausible that Nevill was running for the back door (i.e. the side door on the 'white' side of the house) in the belief that the key was in it and he could make an escape. He would be going out into the night barefoot and in pyjamas, so it's not a perfect theory, but let's remember that he was fleeing an armed lunatic in the middle of the night and didn't have much time for carefully-considered thought. Maybe he had it in mind to flee and try to rouse somebody in the nearby farm cottages.
Here's where I see a problem with it: the lampshade. We're told the glass lampshade in the kitchen was broken and shattered. The background to this is that the prosecution and people who hold to Jeremy being guilty have always maintained there was a struggle in the kitchen. This has been thought to be a point against Jeremy on the basis that Nevill would easily overcome Sheila.
The problems with this theory are:
(a). We are asked to believe that Nevill had been shot four times before even reaching the kitchen, including twice in the head region, but then we have him struggling with Jeremy.
(b). The blood distribution in the kitchen doesn't cohere with Nevill attempting to transit the kitchen to flee. For instance, why are there three blood prints on the worktop?
(c). Following on from (b) above, given that there are blood prints on the worktop, how come, at the very least, there is no blood on the kitchen phone very near it, if not also a recorded 999 call from Nevill?
(d). Adam tells us - and I accept this is plausible (I am not being disrespectful) - that Nevill wasn't running for the phone, but to flee via the kitchen out the back door. So where does the struggle fit into that? How come the lampshade is shattered?
One possibility, which we'll park for now, is that Adam is correct and Jeremy staged the scene by breaking the lampshade, etc., in order to give the impression of a fight or struggle between Nevill and Sheila.
Now let's compare and contrast. Let's see if the above issues can be resolved by making Sheila the killer rather than Jeremy. Interestingly, they can.
Jeremy need not struggle with Nevill if he has a gun, he would just shoot him, but we've already seen the problems with that scenario.
But Sheila would struggle with Nevill because she is not necessarily intending to kill anybody, she is just going crazy with the gun. Nevill would be trying to get the gun off her. One can imagine a scenario in which the lampshade is broken and shattered. Nevill would not be shot upstairs at all - there is no conclusive evidence to say he was anyway - he would be shot once as he ascends the stairs approaching Sheila, then Sheila pursues him back to the kitchen where he intends to round on her and wrestle the gun off her, but she manages to keep the weapon and she fires seven more times into Nevill.
This is consistent with almost-all the evidence, with one exception: the position of the ejected bullet cartridge casings as found and recorded at the scene. The question arises: Is it possible that the other evidence could override the casing positions? Or is there an explanation for the apparent paradoxy in the crime scene? Should we instead accept the recorded casing positions on their face and assume that Jeremy staged the kitchen scene to make it look like a struggle between Nevill and Sheila? If we do accept this, then how do we reconcile this with the forensic evidence and ordinary common-sense?
