On Monday, a jury in Australia found a woman named Erin Patterson guilty of murdering her estranged husband’s parents and aunt by serving them beef Wellington laced with poisonous mushrooms. Patterson had denied the charges, claiming the deaths were an accident.
Here’s a summary of the key points:
WHAT HAPPENED: On July 29, 2023, Patterson invited her former in-laws for lunch at her home in Leongatha, Victoria. She served individual beef Wellingtons, which were later found to contain lethal death cap mushrooms. Gail Patterson, Donald Patterson, and Heather Wilkinson died, while Ian Wilkinson survived.
WHAT DID THE JURY ANNOUNCE: The jury found Patterson guilty on three counts of murder and one count of attempted murder. Sentencing has yet to be scheduled.
WHAT ARE DEATH CAP MUSHROOMS: Death cap mushrooms are the most toxic variety for humans. They contain toxins that inhibit DNA production, leading to organ failure.
WHAT HAPPENED DURING THE TRIAL: The trial opened on April 29 at Latrobe Valley Magistrates’ Court. The prosecution accused Patterson of intentionally foraging and preparing the fatal dose of mushrooms. The defence argued the poisonings were accidental and that Patterson became sick too. Messages on social media suggested a motive related to a child support dispute.
WHAT DO WE KNOW ABOUT THE JURY: A 12-member jury was chosen from an initial panel of 14. The judge instructed the jury to keep emotions out of their verdict, emphasizing that their decision should be based on the evidence, not sympathy or prejudice.
