maybe the ones she didn't use in the dish were dehydrated.
no other reason to use a dehydrator to cook the meal, she rehydrated the Asian food store mushrooms.
unless the dehydrator was multifunction and also worked as a hydrator.
Is that a possibility?
I'm not seeing guilt here.
I think it's normal that she be investigated as she cooked the food..
But what was her motive?
There isn't one, is there?
Dumping dehydrator could just have been normal dumping because it was broken or whatever.
She was independently wealthy, had quite a property portfolio in her own name.. didn't need money and no evidence she would have benefited from the estates of the dead, is there?
