I would like to hear scipio´s take on the state of Sheila´s bed. Can´t deal with your fantasies anymore, Adam, sorry.
She could have slept on top or it could have been made to give the impression she didn't sleep that night. She was in her nightgown so obviously ready for bed. If she were planning to kill anyone I would expect her to put on something easier to move in and not stay barefoot.
If we want to investigate in detail we would need to know more about her habits to see if she did often or at least sometimes sleep on top. I doubt many people knew her habits because who used to go watch her sleeping? You check in on kids, who checks in on an adult? For many years I slept on my bed. If you do it always it should wear the comforter if you don't change it. If you you do it sporadically when it is warm or change the comforter around or even put on a different comforter it might not show a pattern. She didn't sleep at WHF but 3 days so not long enough to leave any tell tale signs one way or the other.
The bottom line is that Jeremy might have staged it like he staged other things or might not have we just don't have enough information to know. If someone reliable said she would never sleep on covers and had to be under sheets no matte rwhat then that would suggest the scene was staged and the bed made.
Given the different possiiblities this issue is not dispositive anymore than a bucket with 2 pairs of soaking panties is. That is why I don't suggest this as more evidence of Jeremy staging the scene, there isn't enough evidence to suggest it is more likely that he staged it than that she just slept on top. I would expect that if Jeremy were staging it he would make the bed flawless so it didn't look like she was even sitting on it. It was not made perfectly though someone could have been sitting on it so I'm not going to chalk it up as proof Jeremy staged it.
Making sure he didn't kill her in bed and that she was killed outside her room I do think was staging. He wanted it to look like she shot June and then herself. Nevill going downstairs actually screwed things up in a number of respects and so did the shot to his voicebox. People worry about minor details but the bigger things that can end up happeing often spoil it. Especially if you don't appreciate the scientific implications of various things.
Jeremy overengineered some aspects like the phone call but failed to adequately consider others.
I would have staged it as a break in so that there was a possiiblity of anyone doing it. I would have made sure to shoot and kill Nevill first because he was the most dangerous and then to shoot June. I would have shouted to get the boys to come to the hall, blocked the stairs and shot them or marched them form their rooms to shoot them and then to kill Sheila in the hall. In this manner it appears thecrook was discovered by the husband and wife and killed then the rest of the house woke up as the killer was trying to run away and then had to shoot them too. Executing everyone in bed is a sign of an execution. A crook need not kill everyone who is sleeping they get out of there and just kill whoever gets in their way. So the goal is to make it look not like an assassinaion.
Of course if you end up getting blood spatter on your body or clothes or having possession of the murder weapon you are toast but it is hard for there to even be a search warrant executed if you stage the crime right.
Sheila would have made a better patsy if she had not been on medication that was being injected by doctors but even then there are more ways to mess up like the suppressor ended up being and you still look like you are framing her if you claim to be a witness against her. Make cops find her and draw their own conclusions. Feeding the flames and claiming the victims called you to tell you what happened is not sound. It makes you involved and that is not what you want. You want to be totally uninvolved and to know nothing.
Police have a hard time pinning anything on you under those circumstances.
