I just cannot wrap my head around Jeremy staging a two shot homicide as a suicide. Makes zero sense to me!
Hi Alias, it's always interesting to read your reasoned and thoughtful take on events. It is, as you say, implausible that Jeremy would carry on with a plan which required Sheila's death to be suicide after apparently messing up the "faked suicide". It would be more likely that he would that he would tailor his plan at this point to account for the new circumstances.
Whilst it is true that everyone on this forum is aware that two shot suicides do occur; most of us, I suspect, only know this from discussions on this forum or from reading about this case. I doubt that many knew this before studying this case. Jeremy is hardly likely to have been reading about two shot suicides and it is reasonable to assume that at the point where he had to make a second shot that he would think that it was now impossible to pass off Sheila's death as self inflicted.
At this point Jeremy would feel that it was imperative to change the plan otherwise he would certainly be caught, especially if he still made the phone call implicating Sheila. Yet we are to believe that not only did he not change course, but that he made the call as planned and then stood all night with police in an apparent siege knowing that as soon as the siege ended he would be implicated as the only suspect.
It makes absolutely no sense at all. He could have changed the phone call from Neville to have said anything he chose but apparently this supposed cunning criminal mastermind didn't possess the nous to change the details after the suicide staging had gone wrong.
He could have decided to make no phone call at all and stage a break in. He had options at this point if he was indeed guilty, but instead he chose the worst option, and one that he would have to assume would lead to his coming under immediate suspicion.
As you say, Alias, it makes no sense.
