Australian Court Increases 'Mushroom Killer' Erin Patterson's Sentence to Life Without Parole

Australia's Victoria Supreme Court has rejected the appeal of Erin Patterson, known as the "mushroom killer," and increased her sentence to life imprisonment without parole. Patterson was convicted of murdering three of her estranged husband's relatives and attempting to kill a fourth using a toxic mushroom meal. The Court of Appeal upheld her convictions while granting the prosecution's appeal to remove her minimum non-parole period.

Originally sentenced in September 2025 to three life terms plus 25 years with a possibility of parole after 33 years, Patterson faced the prospect of release in 2056 at age 82. However, the prosecution argued that the sentence failed to reflect the gravity of her crimes, citing premeditation, the breach of trust, and her lack of remorse. Justice Stephen McLeish emphasized that her actions involved a sophisticated series of deceptions, including faking cancer and destroying evidence, ruling out any future release.

Patterson's defense team presented seven grounds of appeal, all of which were dismissed by the court. Key arguments regarding jurors staying at the same hotel as a police witness and the admissibility of mobile phone data were both rejected. Patterson watched the ruling via video link from the Dame Phyllis Frost Centre, showing no emotion as the decision finalized that she will spend the rest of her life behind bars.
