Back at the start of the case, people suggested that maybe someone placed lethal dried mushrooms in her pantry. And unbeknownst to her, she randomly used them that day and poisoned her loved ones.
At the time, I was open to the possibility. But now, there is too much incriminating evidence against her specifically, for that theory to hold water. IMO
Her defense team has admitted she foraged for the mushrooms but was afraid to admit it. And they found traces of the toxins on the dehydrator she tipped. And she bragged on FB about practicing sneaking mushroom powder into everything.
So that alternate theory is out the window now. IMO
