No.
It becomes very complicated that Sheila was first shot with the silencer attached, then she was shot without the silencer.
Your claim Sheila did not shoot herself puts the blame right back to Jeremy. IMO and in short.
If Sheila was shot it does not necessarilly mean that Jeremy shot her, you are jumping to the wrong conclusion in my opinion, you are jumping to the wrong conclusion because there exists other evidence to support the case for the police having shot her when they went into the farmhouse. You and everybody else who appear hell bent on pinning the responsibility for Sheila's death upon Jeremy, may choose to ignore this evidence, but I can't and won't. You see what we have got are very serious contradictions concerning where police say they originally found the bodies of the victims upon entry to the premises. The jury were never told about these / those discrepancies. How could police find the bodies of one dead male and a dead female downstairs upon entry to the kitchen and a further three bodies upstairs by 8:10am, yet the official version is that only the body of Ralph Bamber was found downstiars, and the other four victims found upstairs? How could police make such fundamental errors about the body count upstairs and downstairs, and when the matter comes to trial they keep the truth from the jury? Why not tell the jury about these mistakes, if they were only mistakes? Can police who work for Essex count beyond the number 1? Do they know the difference between upstairs and downstairs at the scene? Did they know or were they sufficiently tarined to be able to tell the difference between a female and a male? Now, there is nothing complicated about me saying that I believe that one of the shots inflicted to Sheila's neck was caused by a gun with a silencer fitted to the end of its barrel, because I can point you in the direction of a mark around the non fatal neck wound to which bullet entry wound involving the fragmented bullet PV/20, refers. The mark there has the same general characteristics as the dimensions for the end cap of the silencer. How strange that six weeks later, this fragmented bullet (PV/20) should become transformed into a whole one to enable the ballistics expert to confirm that it was fired through the family owned rifle, presented as the murder weapon...
Could you please explain to me, how a fragmented bullet as of 7th August 1985, can become transformed into a whole bullet by 20th September 1985, without the police having tampered with it? Next, if they tampered with it, as they surely must have done, why did they tamper with it?
Now, nothing what I have said is complicated, its all simple, all there for everyone to see and consider, the only problem is that police cannot explain it away without putting themsleves in the shit...
