There were actually some interesting points made in the program. The mycologist Dr Heiki Neuimeister-Kemp said that you would probably need 10 full Death Cap mushrooms to have enough poison for 5 people.
The forensic toxicologist, Dr Miachael Robertson, agreed with her, saying that one DC mushroom would make a person ill, but you might need two DC mushrooms to lead to death. He also said, that if all 5 at the meal (including Erin, ie) had the same dish, you might expect to have different responses to the poison care of the health, age, etc of the person eating - but you would not have had one diner with little to no effect, like EP.
He said emphatically, Yes, when asked if the toxins would have gone into other parts of the meal during cooking. He said, you are going to have leaching of some of the toxin. Therefore, the children should have become ill, ie.
The private investigator pointed out that it wouldn't be the only packet of DC mushrooms on the shelf, and others would have become ill, if it was as EP was suggesting as a result of the dried mushrooms she purchased from an "Asian grocery". They observed there had been no recall of mushrooms... Someone else said wryly, if you need 10 DC to poison this many then that would be almost the whole pack she bought, and how likely was that.
Heiki said that the mushroom food industry is heavily regulated, extremely well-guarded, checked, double-checked, and triple-checked, because of the knowledge that there could be poisonous mushrooms.
Alex Krystic, the former major crime squad detective, asked at some point, "Who organised the lunch?"
Damien the PI, whose been scouring around Leongatha trying to collect info, said "I believe it was Erin."
Alex said that one could rest assured there would be no stone left unturned regarding EP's background, conduct, behaviour, inquiries she's made, and that an incidental comment or admission made by a suspect could well become evidentiary material.
He said at one point, "The truth never changes." And that most people who are genuinely innocent will just give it all to you, warts and all.
Liz Hayes pointed out that in her written statement to the police that EP admits lying to the police about the dehydrator dumping, and asked if that raised questions for him as an investigator. He said, it certainly did, and if it was put to a jury it would certainly allow the jurors to draw their own conclusions...
Those are just the points that stood out to me. I expect it will be up on YouTube shortly, if it's not already there.
