As someone who was friends with her, Erin Patterson is not some dumb country, working class, bumpkin. She is incredibly intelligent and last time I spoke to her she was studying veterinary science and could calculate PI to a ridiculous number of places in her head. Both of her parents were academics and she came from money. She could be really manipulative and could hold a grudge, but when I knew her there was no way she would ever intentionally harm someone like she is being accused of doing.
