Jeremy must have done a good enough job of A) presenting her murder as suicide B) convincing police that she was mentally fragile enough to do it. That a TEAM of shooters can accidentally shoot someone, casually assume they're dead, and step over them is incomprehensible.....................especially as ONE shot from a high calibre police weapon would very likely have done more damage than that of the two shots she sustained, put together. She certainly wouldn't have got up and walked away from that one.
Your speculating without any concrete proof that Sheila wasn't and could not have been the dead (as called) body of one dead female in the kitchen from as early as 7.35am, followed by other timed messages at 7.37am, 7.38am, 7.42am and of course by 7.45am! Cops don't make such glaring mistakes or errors when it comes to passing contemporaneously recorded and timed messages, not on so many occasions without at least somebody at some stage quering what had been told and said by one of their own on as it were several differently timed occasions - cops wouldn't have had sufficient time nor opportunity to falsify these police radio message logs, unlike the contents of their witness statements which could be chopped, changed and edited days, weeks, or months later by which time they could advised about what to leave out, or as the case may be, put in...
The truth of the matter was that Sheila was shot just as cops entered the kitchen and was rendered unconscious immediately, and presumed dead!!!
The fact that the blood flow from the initial shot across the neck appears feint like in its appearance, and vertical in fashion is testimony to the fact that there was only a small amount of bloodflow eminating from the first wound because Sheila was rendered unconscious instanteneously! There was obviously a somewhat protracted delay between Sheila being shot twice because no sooner was she shot a second time blood gushed and flowed from the wound site beneath Sheila's chin! It would appear that there was some truth in what Professor Knight had to say regarding there having been such a potentially lengthy delay in-between both shots! Of course, Sheila wasn't moving around during the entire period in-between shot 1 and shot 2 being inflicted, such a delay was governed by the amount of time Sheila had been rendered unconscious a after the first shot!
