Australia’s mushroom murderer appeals conviction

Australian Erin Patterson, convicted of a 2023 triple-murder involving her husband's parents and an elderly aunt, has launched an appeal against her conviction. Patterson, 51, was sentenced to life imprisonment with eligibility for parole after 33 years for the crimes, which saw her serve lethal death cap mushrooms in a beef Wellington meal.

The Court of Appeal in Melbourne will hear two appeals on Wednesday: Patterson's challenge to her conviction and the prosecution's request for a harsher sentence. Patterson alleges she experienced "substantial miscarriage of justice" due to the trial judge's decision on admissible evidence. Her legal team contends that certain Facebook messages, cell tower data, posts about mushroom sightings, and evidence related to mushroom images found at her home were either irrelevant or unfairly prejudicial to her case.

Additionally, they claim a significant irregularity occurred during the jury's sequestration, which compromised the verdict's integrity. The prosecution, however, argues the sentence of 33 years was inadequate, contending that the judge miscalculated the likelihood of Patterson facing solitary confinement for extended periods. In July, a 12-person jury found Patterson guilty of murdering her husband Simon Patterson, his parents Don and Gail, and his aunt Heather Wilkinson, as well as attempting to murder Heather's husband, pastor Ian Wilkinson.
