I am trying to reconstruct the movement of the rifle, from whichever window Jeapes saw it at around 7.15am? That sighting has to be treated as a starting point of the gun (the weapon police claim fired both bullets into Sheila Caffells neck). It was definitely 'not' used to inflict the first shot across her neck, but certainly used to inflict the fatal shot under her chin. This means that at some stage, the rifle was brought from that window to her body. This did not happen until after PS Adams left the bedroom at around 9am, at a time when he says there was no rifle at all present upon Sheila's body...
At around this stage, a training exercise got underway (familiars) which involved someone bringing the rifle from the window to her body to see if she could have used it on the other four victims. At this time Sheila's right hand fingers were being manipulated against the trigger mechanism, and upon trying to identify it as being capable of activating the trigger, it discharged the fatal round still loaded in the gun up through her chin, mouth and deposited itself in her brain. No sooner did this happen, than someone removed the rifle from her body and stood it against the main bedroom window as per photograph No. 23. This took place at around 9.13am, and it remained there at the bedroom window, until someone brought it back to Sheila's body after 10.13am, when it was positioned back upon Sheila Caffells body and PC Bird took photographs, 26, 27, 28, 29, 30, 31, 32 and 33. After this, Ron Cook himself removed the rifle from Sheila's body and replaced it against the main bedroom window, but not as shown in photo' 23...
