Erin Patterson, known as Australia's mushroom killer, has failed in her attempt to overturn her murder convictions following an appeal hearing in Victoria. The Court of Appeal unanimously rejected all seven grounds presented by her legal team and agreed with the prosecution that her original sentence was inadequate because it allowed for the possibility of future freedom.
Patterson, 52, was convicted last year of murdering three relatives and attempting to kill a fourth after serving them a meal laced with toxic death cap mushrooms in 2023. The victims included her in-laws, Don and Gail Patterson, and Gail's sister, Heather Wilkinson. Ian Wilkinson, Heather's husband and a local pastor, survived the poisoning but remains hospitalized for weeks and suffers from ongoing health issues.
During the appeal proceedings on Friday, the three-judge panel described Patterson's crimes as "extraordinarily cold and calculated," stating they must be denounced in the strongest terms. Justice Stephen McLeish, speaking for the panel, declared that the shocking nature of the criminality made it inappropriate to fix a non-parole period. Consequently, Patterson will now serve a life sentence with no chance of parole.
The defense had argued that the original trial was unfair due to several factors. They claimed a hotel booking error, which placed the jury in the same location as the prosecution, a key police witness, and media personnel, was catastrophic for the trial's integrity. Additionally, they contended that certain evidence presented to the jury, such as cell tower data and Facebook posts regarding her in-laws, was irrelevant and prejudicial.
The defense also asserted that the trial judge wrongly excluded evidence of Patterson's long-time hobby of mushroom foraging and argued that the prosecution's five-day cross-examination was oppressive. They further claimed inconsistencies in the Crown's arguments regarding motive. However, the appeal judges dismissed all these claims on Friday.
Patterson was originally sentenced last September to life imprisonment with a 33-year non-parole period, a decision the trial judge made considering the harsh prison conditions she would face. Her estranged husband, Simon Patterson, had been scheduled to attend the fatal lunch but canceled at the last minute due to his belief that his wife had repeatedly attempted to poison him over several years. Patterson now has 28 days to decide whether to seek leave from the High Court of Australia for another appeal.
