Quick Takes
- Erin Patterson is on trial for allegedly serving poisonous mushroom-laced Beef Wellington that killed three family members and hospitalized one.
- The fatal meal was served on July 29, 2023, to her former in-laws and their relatives, with witnesses noting Patterson ate from a different plate.
- Patterson faces three counts of murder and one count of attempted murder, with prosecution alleging “murderous intent.”
- The defense claims the poisoning was accidental, despite Patterson’s initial denials about foraging for wild mushrooms.
- Patterson allegedly lied about having cancer and disposed of evidence, including a food dehydrator.
Deadly Dinner Party Leads to Murder Charges
The trial of 50-year-old Erin Patterson began this week in Victoria, Australia, where she faces three counts of murder and one count of attempted murder. Patterson is accused of serving death cap mushrooms in a beef Wellington dish during a lunch at her home in Leongatha on July 29, 2023. The guests included her former parents-in-law, Gail and Don Patterson, along with Gail’s sister Heather Wilkinson and Heather’s husband Ian. Within days of the meal, Gail and Don Patterson and Heather Wilkinson were dead, while Ian Wilkinson spent seven weeks hospitalized before recovering.
Death cap mushrooms, responsible for 90% of fatal mushroom poisonings worldwide, can easily be mistaken for edible varieties. Prosecutor Nanette Rogers alleges Patterson deliberately incorporated these lethal fungi into the meal with “murderous intent,” targeting her ex-husband’s family members. The prosecution has emphasized suspicious behavior, including Patterson’s decision to eat from a different plate and her disposal of potential evidence after the incident. The trial is being held at the Latrobe Valley Law Courts in Morwell and is expected to continue for six weeks.

Suspicious Circumstances and Alleged Deception
According to court testimony, Patterson claimed the purpose of the lunch was to discuss medical issues and seek advice about how to communicate with her children. Notably, her own children were absent from the fatal meal. One of the victims, Heather Wilkinson, made a crucial observation before her death that has become central to the prosecution’s case. She noted that Patterson served herself food on a different, colorful plate separate from the guests, raising questions about why the hostess would make such a distinction.
“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 said.
Further complicating matters, Patterson allegedly fabricated a cancer diagnosis to explain her children’s absence from the lunch. “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,” prosecutor Nanette Rogers told the court. The prosecution also claims Patterson’s children ate leftovers from the same meal but without the mushrooms, and they remained unharmed.
Defense Claims Accidental Poisoning
Patterson’s defense team maintains that the poisoning was accidental rather than deliberate murder. Despite initially denying that she foraged for wild mushrooms, Patterson later conceded that she had personally gathered the mushrooms used in the dish. Her legal representatives argue she had no intention to cause harm and that her subsequent actions stemmed from panic rather than guilt. “The overarching issue is whether she intended to kill or cause very serious injury,” Justice Christopher Beale explained to the jury of 15 at the start of proceedings.
Curiously, while addressing the jury, prosecutor Rogers acknowledged a question on many observers’ minds: “You might be wondering, ‘What is the motive?'” The prosecution has hinted at a possible connection to Patterson’s relationship with her ex-husband, noting, “Simon remained hopeful for some time that he and the accused would someday reunite.” The trial will include testimony from numerous witnesses, including the surviving guest, medical personnel, and investigating officers. The judge has urged jurors to maintain an open mind and focus strictly on evidence presented in court as the case unfolds over the next six weeks.
