The other thing that is remarkable is that all of her excuses were retrofitted to the evidence. I was looking for one example where she acted in a way that supported her story before information was revealed to her, but I didn't see any.Evidence in a criminal trial is like a jigsaw puzzle: one piece by itself tells you nothing, but put the pieces together and a picture starts to emerge. Once all the pieces are in place, the picture is very clear.
Take the mismatched plates. First, are you implying that Ian is lying? Why would he lie? If you think he was mistaken, remember that he first mentioned that a day or two after the poisoned lunch, so obviously it was something that struck him as odd. There has been no hint that he has a faulty memory so when he says Erin served the guests on grey plates but used an orange one for herself, I believe he is very credible. The police didn't find any such plates at her home - well we now have CCTV footage of Erin at a garbage tip, just 30 minutes after her guests had left, throwing a cardboard box into the trash. It's reasonable to assume the plates were in the box.
As for her son, he testified that there were white plates, not grey or orange ones, in the dishwasher. But they were smaller than dinner plates, so obviously dessert plates. Sure, if you only own four good plates but there are five people at lunch including yourself, then you'd use the good plates for your guests and use another one for yourself. However, when you look at all the other pieces of evidence, a benign explanation is very unlikely. And that's just for one part of the evidence.
She claims she thought she had gastro illness but didn't call her more vulnerable lunch guests to warn them that evening, and ask if they were sick too, or call and ask Simon to keep an eye on them. Because she wasn't really sick and being sick wasn't part of her original plan.
She served the same food to her children that she thought may have made her sick. Because Erin being sick wasn't part of her original narrative, if they'd died and not revealed they ate specially prepared portions, and not shared a single large wellington.
She didn't tell anyone about the dried wild mushrooms until she heard they were treating the patients for death cap poisoning. Because she planned to say they were only button mushrooms from Woollies. She hid the dehydrator for the same reason.
She admitted foraging at trial and not before, when she knew the grocer story was not credible and they'd found traces to prove she'd dried the death caps in her own kitchen. There would have been no reason to dry already dried mushrooms from a store.
If she'd got ahead and said one of these things before she found out what police and doctors were doing I might have given her a teeny bit more benefit of the doubt.
