I have said it so many times, but people just don´t accept what I say. So be it.
Some people accept it Alias. Had Jeremy committed the murders, I agree that once the need for a second shot arose, then he would surely have felt that it would not be possible to pass off Sheila's murder as suicide. It is argued that because two shot suicides are viable and do indeed happen then Jeremy would have felt no need to change the plan. Even if Jeremy had been aware of this, which I think unlikely, he could not be confident that Sheila's death would easily be accepted as such.
This alongside the fact that he also messed up by using the silencer, which he discovered was too long for Sheila to have committed suicide, so he had to replace it in the gun cupboard after murdering Sheila. Oddly he didn't discover the fact that the silencer was too long until after the second fatal shot. There are two, rather than one, massive blunders in the staged suicide scenario and yet supposedly neither of these blunders made Jeremy change course.
Anyway after putting the silencer back, which was too long, he coolly invents a phone call and convinces Essex Police and armed units to remain outside for hours with his cunning, or so we are led to believe.
You are right Alias, this part of the prosecution case sounds so unlikely that it merits scrutiny.
