What I would ask you to bear in mind in addition to what I am saying, is that Professor Knight had seen photographs of Sheila's body, the extent of her injuries, and the condition of her nightdress, and directional blood flow on her body and the aforementioned nightdress, yet at one stage he testified to the fact that in his expert opinion it might have been possible for Sheila to have been shot on the first occasion, and that she could have moved around for half an hour before she might collapse if she had not received the second fatal shot which effectively killed her immediately. Think about what Professor Knight testified about. Basically put he was advocating the two shots possibly being as long as 30 minutes a part, not consecutively inflicted as in recoil. I found his testimony very helpful, because understanding what he was trying to say made complete sense to me, to explain the delay in between Sheila having been shot downstairs in the kitchen at 7.37am, she laying on the kitchen floor for about 30 minutes as if dead, regaining consciousness, getting to her feet and making her way upstairs to the bed in her parents bedroom. Collapsing on the bed with only one shot in her throat on the verge of death, but not quite dead. I think Knight got it almost spot on, except for the fact that Sheila had not been running amok for half an hour after she had been shot downstairs. She didn't run amok, the contents of the police message log tell us this. She laid there on the kitchen floor for about 30 minutes, then got up briefly made her way to the bed in her parents bedroom and collapsed just like Knight said he thought she might do...
Armed with the testimony of Professor knight and against a backdrop of the police message log contents which had two bodies downstairs and three bodies upstairs by 8.10am, versus the police witness statement versions which had one body downstairs and four bodies upstairs, I was able to reconstruct what 'had' taken place, enabling one version to change into the other version of events, with Sheila shot and mistakenly believed to be dead right at the heart of the matter. Laying on the kitchen floor as if dead for around 30 minutes - that is how I untangled the truth in this convoluted operation / investigation...
Understanding 'the sequence of events', paid off again...
