She also invited her estranged husband, who she had separated from in 2015, but he did not attend.

She arranged the lunch to tell her relatives about what later turned out to be a false cancer diagnosis and discuss how to tell their children.

Authorities found that Patterson had disposed of evidence, including resetting her phone to eliminate photos of mushrooms and disposing a food dehydrator that contained the remains of the death cap mushroom.
