Good morning Gillian,,and thankyou for this enlightening news.,
My daughter works with retired police on border control,,and one of the guys last year had said pretty much the same as the retired DI in your post,,and he couldn't understand how it went to trial at the time and said he was awaiting the forensic report/evidence------------which didn't appear.
However,,I remember this case vividly back in 1985,,and my first thoughts were that Jeremy hadn't done it. At that point I was obviously trying to fathom out who had,,but with no internet at the time,I wasn't able to keep track of how the case was going,,until years later when I back-tracked after joining this forum 18 months ago. It all became clear after reading posts from the archives,,and having also been a nurse in a then " asylum " that it wasn't impossible for Sheila to have committed the murders,then taken her own life,,having had dealings with these sick people.
Nothing,,at any time,convinced me that it was Jeremy,,who'd been made a terrible scapegoat for these crimes,,had committed anything.He's told the truth all along and never faltered in his belief of himself that he's totally and wholly innocent.
Let's hope that this is the first chapter in his quest for his longed-for freedom.
