I think your last sentence is assumption you do not know the order of the shootings as it has never been proven. And if you backed up against that bedside table I bet you the lamp would at least topple over .
And he still had to get her in the right position to get the shots to look like suicide that is not a simple thing to do .
1) I do know the general order of the shots I presented a very detailed assessment of such.
2) That assessment makes it quite clear that either the boys were killed last or Sheila was killed last. Logically Sheila would be the last one killed and the only way she would not be killed last would be if she was out of her room when Jeremy walked up from the kitchen after killing Nevill there
3) If Sheila was still in bed and thus the boys were killed before her then Jeremy woke her she would not have known they were dead. Thus he could threaten to harm them unless she complied and she would not know he had already murdered them. I have pointed this out countless times in the past.
