What Jeremy is doing right now,i.e. digging and delving into what he thinks happened,and by who and how is what all innocents do to look for the truth and what he hopes to do is to raise the serious doubt about the evidence which was against him.
This was why he first learned about mental health and the serious implications it can have,after having blamed Sheila for the massacre.
My other argument is why,when Jeremy FIRST blamed Sheila,weren't steps taken to look into Sheila's history with her GP/Psychiatrist,privately,to get an overall picture of her behaviour as part of the investigation ?
The first thing an alleged murderer does is blame someone else,so it would have been a vital part of this investigation to have looked at Sheila's background.
Jeremy made one big mistake at the very beginning by not ringing 999. His second was not engaging a solicitor immediately. Because he should have realised at the time that he was the only family member remaining,so should have acted quickly because he'd have been implicated.Did he not know this ? Didn't it dawn on him at the time that he'd get the blame anyway ? He couldn't have been advised very well if at all.
I can only hope that there's a strong enough breakthrough when his next submission is accepted.
