Australian Woman Convicted of Mushroom Murders Also Allegedly Poisoned Husband Over Years
Leongatha, Australia – August 8, 2025 – Erin Patterson, the Australian woman recently convicted of the murders of three family members thru deliberate mushroom poisoning, is now facing scrutiny over a disturbing pattern of alleged attempts to poison her estranged husband, Simon Patterson, over a period of two years. Newly revealed evidence, previously suppressed to protect potential appeal rights, details a series of illnesses suffered by Mr. Patterson following meals prepared by his wife, raising chilling questions about the extent of her calculated malice. This case has captivated Australia and sparked a national conversation about food safety,domestic abuse,and the complexities of criminal intent.
The Deadly Lunch and Subsequent Conviction
Last month, a jury found Erin Patterson guilty of murdering her mother-in-law, Gail Patterson; her father-in-law, Don Patterson; and Gail’s sister, Heather Wilkinson.The victims succumbed to the effects of death cap mushrooms, a highly toxic species, after consuming a Beef Wellington prepared by patterson at her home in Leongatha, a small town approximately 84 miles southeast of Melbourne. She was also convicted of the attempted murder of Heather Wilkinson’s husband, Ian Wilkinson, who survived the meal but suffered severe illness.
The prosecution successfully argued that Patterson deliberately incorporated the deadly mushrooms into the meal, meticulously planning a horrific act that decimated a family.The case hinged on forensic evidence linking the mushrooms to Patterson’s garden and circumstantial evidence demonstrating her motive and opportunity.
A Pattern of Alleged Poisonings: Simon Patterson’s Ordeal
Prior to the trial focusing on the deaths of her in-laws, Patterson faced initial charges including five counts of attempted murder, four of which related to her estranged husband, Simon Patterson. These charges were later dropped by the prosecution before the first trial, leading to the suppression of evidence detailing the alleged attempts on his life. Justice Christopher Beale has now lifted those restrictions, revealing a harrowing account of Mr. Patterson’s repeated illnesses.
According to testimony given during a pre-trial hearing in October 2024, Mr. Patterson began to suspect his wife was poisoning him after experiencing a series of unexplained illnesses following meals she prepared. He meticulously documented these incidents, creating a spreadsheet detailing the dates, meals consumed, and subsequent symptoms. These meals included a penne bolognese,a chicken curry,and a sandwich wrap – seemingly innocuous dishes that allegedly concealed a deadly intent.
The alleged poisonings occurred during camping trips and even a casual walk, leaving Mr. Patterson in a precarious state of health. He experienced temporary paralysis and required the removal of part of his bowel. Crucially, despite extensive medical examination, doctors were unable to definitively identify the cause of his illnesses, hindering early intervention and potentially exacerbating the severity of his condition.
Raising the Alarm: A Family’s growing Suspicions
Mr.Patterson’s concerns were initially dismissed, but he persistently raised his suspicions with his doctor and family members.His father, Don Patterson, became particularly convinced that he had been poisoned, a belief that tragically proved prescient.In a chilling act of foresight, Don Patterson arrived at the hospital following the fatal lunch with a container of his own vomit, requesting it be tested for toxins. This act underscores the depth of his suspicion and the terrifying realization that he was facing a deliberate attack.
The Search for Answers: Evidence and Suppression
Investigators seized a computer from Patterson’s home and discovered searches related to various poisons. However, this evidence was excluded from the initial trial, a decision that drew criticism from some observers. Justice Beale initially ordered the suppression of pre-trial materials to safeguard Patterson’s appeal rights,but ultimately reversed that decision on Friday,citing the importance of “open justice” - a basic principle of the Australian legal system.
Appeal Prospects and the Path Forward
Erin Patterson has 28 days from the date of her sentencing to file an appeal. While Justice Beale acknowledged that an appeal could not be entirely ruled out, he indicated that its chances of success were slim. Patterson has consistently maintained her innocence, claiming the deaths were a tragic accident. She pleaded not guilty to the attempted murder charges relating to her husband.
The court will reconvene on August 25th for a two-day plea hearing
