Killing everyone, inside whf (June, the twins, Neville Bamber, and Sheila) would have been 'akin to inviting trouble upon himself' from the outset, trouble that someone in Jeremy's position could well afford to do without!
What's your view on this situation?
Now..
Despite all arguments to the contrary..
Sheila was 'not shot dead', either by her own hand, or by a hired hitman, or by Jeremy himself, she survived being shot downstairs in the kitchen by 7.35am, she survived being pronounced as dead on the far side of the bed (8.44am), and she survived being presumed dead whilst laying on top of the bed at 9.05am, and eventually she ended up as literal!y being dead on the bedroom floor between 9.05am, and 9.30am, that morning...
Let's, forget about who shot Sheila Dead after 9.05am...
I say 9.05am, because according to Stan Jones, and Mick Clark, who visited the main bedroom crime scene at about 9.05am, they saw Sheila Caffell's body on the bed, she had a Bible on her chest, and she only had been shot once in the neck by 'that' stage..
There was no gun on Sheila's body at this time, the rifle was resting on the bed, in between the bodies of Sheila and June!
How did the rifle that was resting on the bed in between the bodies of June and Sheila, at 9.05am, manage to be placed in the possession of Sheila Caffell's body on the bedroom floor, in time for DC Oakey (prior to 10.00am), and then for PC Bird (after 11.00am) to capture this in evidence?
