Erin Patterson is a 49-year-old Australian woman who was arrested on November 2, 2023, in connection with the alleged killer mushroom poisoning of three ex-in-laws.
Her former mother and father-in-law, Gail and Don Patterson, both 70, along with Gail’s sister Heather Wilkinson, 66, all died in the hospital days after they ate the Beef Wellington pie she cooked them.
Wilkinson’s 69-year-old husband, Ian, was also rushed to the hospital in critical condition and remained hospitalized for months until he was released on September 23.
Patterson was the only person who walked away from her lunch and didn’t get sick, along with her ex-husband who was supposed to join his family for lunch but skipped it at the last minute.
She has been charged with triple murder and five counts of attempted murder, three of which allegedly happened in previous years.
