Deadly Dinner Party Leads to Murder Trial
Erin Patterson’s trial began this week in Victoria, Australia, where she stands accused of deliberately poisoning four guests with death cap mushrooms concealed in a Beef Wellington dish. The July 29, 2023 lunch in Leongatha, Victoria, resulted in the deaths of her former in-laws, Gail and Don Patterson, as well as Gail’s sister Heather Wilkinson. Heather’s husband, Ian Wilkinson, survived after spending seven weeks in the hospital. Patterson faces three counts of murder and one count of attempted murder, with the trial expected to last six weeks at the Latrobe Valley Law Courts in Morwell.
According to prosecutor Nanette Rogers SC, Patterson invited the guests under false pretenses, claiming she needed to discuss medical issues. “She said the purpose of the lunch was to discuss some medical issues that she had and to get advice about how to break it to the kids. The accused said that it was important that the children were not present for the lunch,” Rogers told the court.

Suspicious Behavior and Conflicting Claims
Prosecutors presented evidence suggesting Patterson deliberately avoided consuming the same poisoned meal as her guests. One crucial detail came from victim Heather Wilkinson before her death. “I noticed that Erin put her food on a different plate to us. Her plate had colors on it. I wondered why that was. I’ve puzzled about it since lunch,” Wilkinson reportedly stated, raising questions about Patterson’s intentions during the fatal gathering.
“After the lunch, the accused announced that she had cancer and asked for advice on whether to tell the children or keep it from them. They had a discussion about it being best to be honest with the children. They prayed as a group for the accused’s health and wisdom in relation to telling the children,” Rogers claims.
The prosecution further alleges that Patterson lied about having cancer to explain her children’s absence from the lunch and later disposed of evidence, including a food dehydrator. Her children, who weren’t present at the lunch, ate leftovers without mushrooms and remained unharmed. Though Patterson initially claimed she suffered symptoms after the meal, prosecutors contend this was part of her deception.
Conflicting Accounts of Mushroom Source
A central question in the trial involves the origin of the deadly mushrooms. Death cap mushrooms are responsible for approximately 90% of fatal mushroom poisonings worldwide and can be easily mistaken for edible varieties. Initially, Patterson denied foraging for wild mushrooms, claiming she used commercially purchased mushrooms. However, the prosecution alleges this was a deliberate falsehood noting that Patterson later changed her story, admitting to foraging for the mushrooms.
Patterson’s defense team argues the poisoning was accidental and that her actions afterward stemmed from panic rather than guilt. Justice Christopher Beale emphasized to the jury that the core issue is intent: “The overarching issue is whether she intended to kill or cause very serious injury.” Prosecutors have suggested a potential motive might involve Patterson’s former relationship with her ex-husband Simon, noting that “Simon remained hopeful for some time that he and the accused would someday reunite.”
A jury of 15 has been selected for the trial, which will eventually be reduced to 12 as proceedings continue. The case has generated significant media attention, with numerous journalists covering the trial and the story inspiring podcasts and a documentary series. The court has instructed jurors to keep an open mind and focus solely on the evidence presented.
