Roch, what one piece or pieces of evidence make you think Sheila? I personally think it was her to, I can't see her laying down to be shot in the neck totally compliant.
Is that you're basis for believing Sheila comnitted the massacre ?That a fit young man holding a rifle couldn't move her a few feet & shoot her.
Sheila was asleep & on Haloperidol. So wouldn't of had a clue what was happening.
You can't explain how Sheila committed the massacre. You've just said Nevill phoned Bamber & the police 16 minutes later after he was shot 4 times. Which was impossible as he couldn't speak. Sheila couldn't brutally beat Nevill. He was 15 stone & 6.4.
