Cliff without viewing Junes fatal injuries im sure June had the worst of them, its no secret that June and Sheila never really got on.I only picture Sheila on a rampage .
This my point. It seems that Shiela hated her mum, but had a common cause.
June may have thought she was doing the kids a favour.
If we are to believe that Jeremy did not do this, then it was someone else in the house, and I cannot believe it was Shiela alone.
Of course this is only speculation, and I only posted for debate, not as fact.
Regards.
The idea doesn't get off the launch pad as far as I am concerned. June's own mental health issues that took in religious excess would be the last thing Sheila needed to cope with her own mental health issues. June probably played a large role in triggering Sheila's eposode of madness that night. As an analogy ..the fuse for the bomb that was waiting to explode that was Sheila.
Physically Sheila would have been empowered by her schizphrenia and no real physical effort was needed to carry out the killings of June and the twins. Ralph himself may have been struck a few times by either swung or thrown objects which would not have injured Sheila but could reasonably have incapacitated Ralph let alone what the rifle bullets would have done to him.
While Sheila would be energised by her schizphrenia its likelt when attacked that the fairly olf Ralph would have been tired from a long days work on the farm coupled with dealing with June , Sheila and the twins. Ralph may have been very weary from tiredness and this would have hampered his ability to defend himself and restrain the mad Sheila.
