Mushroom Poisoning: Australian Court Denies Erin Patterson Parole

Three judges in the Victoria state Court of Appeal ordered Erin Patterson to serve the rest of her life in prison without the possibility of release. The ruling, issued on Friday, overturned a previous 33-year non-parole period set for the convicted killer.

Patterson was sentenced last year to three life sentences for murder and 25 years for attempted murder. Prosecutors argued during an appeal hearing in August that her eligibility for parole should be removed entirely. The court agreed, citing the specific nature of her crimes.

Justice Stephen McLeish spoke on behalf of the panel. He described the offending as "extraordinarily cold and calculated." The judges concluded that the case involved "shocking criminality" that made fixing a non-parole period inappropriate. They also rejected Patterson's challenge to her original convictions.

The convictions stem from a family meal hosted at a rural home in Leongatha in July 2023. Patterson poisoned four of her estranged husband's relatives using death cap mushrooms. Don and Gail Patterson died within days of the lunch, as did Gail's sister, Heather Wilkinson. Ian Wilkinson, Heather's husband, survived after weeks in hospital. Patterson was found guilty of his attempted murder.

Patterson has maintained that she added the toxic mushrooms to the meals by accident. She watched the verdicts via video link from prison and did not attend the hearing in person. Because of her high public profile, she is held in the high-security Gordon Unit of Melbourne’s Dame Phyllis Frost Centre women’s prison. The unit houses inmates assessed as high risk. The case has since inspired podcasts, books, and screen adaptations.

Patterson can apply to Australia's High Court to overturn both her sentence and her convictions. The High Court represents her final option for appeal.
