No danger of poisoning if you were to eat edible mushrooms that were dried in a dehydrator previously used to dry death caps with spores and other microscopic traces of death cap remaining in the dehydrator.I wonder, if she had used the dehydrator to dry out and powder death cap mushrooms that weren't in the meal and then later used it to make the mushrooms for the BW?
To my mind this would make the most sense as it buys into the concept she was trying to poison her husband at some time but not wipe out four other people. That theory would rely on the tiniest particles of DC mushrooms cross contaminating to be enough to cause death. This also complies with a previous police statement where they said something about it may be the case there was an intention to perpetrate some form of other nefarious behaviour. ie. she prepared DC mushrooms, powdered them, intended to poison SP at the meal probably, used the dehydrator without cleaning it for the prep of the BW, cross-contaminated only tiny amounts of DC mushroom which was still enough to kill most of the elder people.
If this was the case and Erin ate the same meal as her guests, how did she avoid ending up on deaths door?
