I know, I remembered reading about the detail concerning the plastic in either the late 1990s or early 2000s, and I always thought it was so strange. I wondered if maybe it had been 'newspaper talk' amid the sensationalism at the time, but I was surprised to find while researching the case again that it still seems to be widely reported as fact. I'm also at a loss to understand why 'Mr B' wasn't further investigated (or why the police don't make public the reasons why he was dismissed to clarify matters)! Thanks for your comment and for the read, Rebecca!
