An Australian woman, Erin Patterson, was convicted on Monday of murdering three of her estranged husband’s family members by intentionally serving them poisonous mushrooms during a lunch.
After six days of deliberation, a jury in Victoria’s Supreme Court delivered the guilty verdicts following a nine-week trial that captivated the nation. Patterson now faces a potential life sentence, with her sentencing hearing yet to be scheduled.
Patterson, seated between two guards in the dock, remained expressionless as the jury’s decisions were read, though she blinked rapidly.
Three of the four guests at the 2023 lunch hosted at Patterson’s Leongatha home — her parents-in-law, Don and Gail Patterson, and Gail’s sister, Heather Wilkinson — died in the hospital after eating individual beef Wellington pastries containing death cap mushrooms.
Patterson was also found guilty of attempting to murder Heather’s husband, Ian Wilkinson, who survived the meal.
The jury determined the poisoning was deliberate
There was no dispute that Patterson served the meal or that the mushrooms caused the deaths. Jurors had to decide whether she knowingly included the deadly fungi and intended to kill her guests.
The unanimous verdicts indicated jurors rejected Patterson’s claims that the poisonous mushrooms were unknowingly included, possibly gathered while foraging. Prosecutors did not present a specific motive but pointed to Patterson’s strained relationship with her husband and previous frustrations with his parents.
The case centered on whether Patterson had carefully orchestrated a triple murder or unintentionally killed three loved ones — who were also the only surviving grandparents of her children. Her defense argued there was no reason for her to commit such a crime, highlighting her comfortable lifestyle, recent move to a desirable home, sole custody of her children, and plans to begin nursing and midwifery studies.
However, prosecutors portrayed Patterson as having a dual personality — outwardly maintaining good relations with her in-laws, while harboring resentment privately. They noted her relationship with estranged husband Simon Patterson, who declined the invitation to the fatal lunch, had deteriorated in the year leading up to the incident.
Every aspect of the fatal meal came under scrutiny
While the sequence of events was largely undisputed, Patterson’s intentions were thoroughly examined throughout the lengthy trial, which featured testimony from over 50 witnesses.
One key detail was Patterson’s choice to serve individual beef Wellington portions, despite the recipe calling for a single large pastry. Prosecutors argued this allowed her to poison select portions, excluding her own. Patterson, however, claimed she couldn’t source the right ingredients for the full-sized version.
Other details were rigorously analyzed, such as Patterson sending her children to a movie before lunch, adding dried mushrooms from her pantry, her lack of severe illness compared to the other diners, and the disposal of a food dehydrator, which she initially denied owning.
During her testimony, Patterson admitted lying about never foraging mushrooms or owning a dehydrator, saying she panicked after realizing people had died from the meal.
She also explained that she vomited after eating, attributing this to an eating disorder, which, she said, spared her from the others’ severe symptoms. Patterson denied claims that she lied to her guests about having cancer to lure them to her home that day.
The case fascinated Australia
The shocking case has captivated public and media attention across Australia. Throughout the trial, five different podcasts provided daily analysis, while multiple news outlets ran live blogs covering nearly every moment of the proceedings.
Plans for a television drama and documentary about the case are already underway. Well-known Australian crime authors attended the trial regularly.
Ahead of the verdict, dozens of people queued outside the courthouse in Morwell, eager to witness the outcome. Media reports said no immediate family members of the victims were present.
Photos published earlier showed black privacy screens around Patterson’s home. Reporters from across Australia and abroad gathered outside the courthouse to speak with Patterson’s acquaintances.
“I’m saddened, but it is what it is,” said Patterson’s friend, Ali Rose Prior, who wore sunglasses and appeared emotional. When asked about Patterson’s reaction to the verdicts, Prior replied, “I don’t know.”
Prior, who attended the entire trial, said Patterson told her, “See you soon,” and confirmed she plans to visit her in prison.
