The gist
Erin Patterson appeals her triple-murder conviction over a 2023 death cap mushroom beef Wellington lunch. The appeal outcome could overturn her life sentence or order a retrial.
Background
Erin Patterson was convicted in 2025 of murdering three relatives—Don Patterson, Gail Patterson, and Heather Wilkinson—by serving them a beef Wellington lunch laced with lethal death cap mushrooms at her home in Leongatha, Australia. She was also convicted of attempting to murder Heather's husband, Ian Wilkinson, the sole survivor. She was sentenced to life imprisonment with a non-parole period of 33 years. Her appeal, heard by three judges at the Court of Appeal in Melbourne, claims a 'substantial miscarriage of justice' due to the trial judge's evidentiary rulings.
