An Australian court has convicted 50-year-old Erin Patterson of murdering three people at a family dinner, including her husband's parents, Don and Gail Patterson, and Gail's sister, Heather Wilkinson, as well as the attempted murder of another person. According to the charges, Patterson poisoned them to death after serving them a meal in July 2023 that contained extremely toxic mushrooms known as "death cap mushrooms." The jury in the case found her guilty on all four charges against her.
