Erin Patterson Loses Appeal and Parole Date in Mushroom Case

Sydney (GNP): Erin Patterson, the Australian woman convicted of murdering three relatives with a poisoned meal, has lost her appeal against her convictions, and a court has also removed the fixed date on which she could first seek parole.

The Supreme Court of Victoria rejected her appeal on Friday, ruling that her arguments did not provide enough grounds to overturn the verdicts. The 51-year-old had challenged the admission of certain evidence, the fairness of her cross-examination and a jury-related issue involving accommodation arrangements during the trial. She has consistently denied wrongdoing and maintains that the deaths were accidental.

In a separate ruling, the court upheld a prosecution appeal against her original sentence. That removed the 33-year non-parole period imposed alongside her life sentence, which means she now has no scheduled date for parole eligibility.

Justice Stephen McLeish, speaking for a three-judge panel, described the crimes as extraordinarily cold and calculated. The judges concluded that the seriousness of the offending made it inappropriate to set a fixed non-parole period.

The ruling closes a case that began with a lunch in July 2023 at Patterson’s home in Leongatha, southeast of Melbourne. A jury found that she invited her mother-in-law Gail Patterson, her father-in-law Donald Patterson and Gail’s sister Heather Wilkinson to the meal. She was found guilty last year of murdering the three elderly relatives of her estranged husband after serving them Beef Wellington contaminated with deadly death cap mushrooms.

All three died after eating the meal. Heather Wilkinson’s husband, Ian Wilkinson, also became seriously ill but survived, and Patterson was convicted of his attempted murder.

The 11-week trial drew international attention and inspired several podcasts and books. The case is now set for a television adaptation, with Paramount+ announcing this week that New Zealand actor Melanie Lynskey will play Patterson in a six-part series.
