Angelo222 and John

The DNA evidence really is "utterly meaningless" as per the outcome of the CoA 2002 hearing due to the very real risk of contamination.
IMO the evidence is anything other than "crystal clear". As far as I can see there is not a scintilla of evidence to support JB's conviction just much myth, gossip, rumour, hearsay etc.
The moment Jeremy mentioned a phone call from Nevill and spoke of Sheila with the gun was the moment it all unravelled for him. In order to prove that Jeremy is innocent you have to prove that Sheila is guilty, but it is the reverse which prevails.
The evidence which clears Sheila of any involvement is overwhelming and it is this evidence which convicts Jeremy by default. There is no need to prove Jeremy did this or that as it is irrelevant. The further evidence by Julie Mugford, Barbara Wilson and others only serves to compete the circle and render it a fait accompli.
Jeremy's invented telephone call from his father was his undoing. Had he not invented it the case might never have been solved.
