Melbourne, Australia July 7, 2025. In a chilling case that has gripped Australia and sparked international headlines, Erin Patterson, 50, has been found guilty of murdering three of her relatives and attempting to murder a fourth by serving them a lunch laced with deadly death cap mushrooms.
The verdict, delivered by a Victorian Supreme Court jury after an 11-week trial, brings to a close one of Australia's most sensational criminal trials in recent memory.
The Poisoned Lunch That Shocked a Nation
The tragic events unfolded on July 29, 2023, when Patterson hosted a lunch at her home in Leongatha, a small town in Victoria’s Gippsland region. The lunch menu featured a homemade beef wellington, later discovered to have been contaminated with Amanita phalloides, commonly known as death cap mushrooms one of the world’s deadliest fungi.
Within days:
Gail Patterson and Heather Wilkinson died on August 4, 2023.
Don Patterson succumbed the following day on August 5.
Ian Wilkinson, the only survivor, spent several weeks in critical care before being released to a rehabilitation ward in September 2023.
All four guests had been diagnosed with mushroom poisoning, according to expert testimony presented during the trial.
Prosecution: Deception and Deadly Intent
The prosecution, led by Senior Counsel Nanette Rogers, alleged that Patterson had carefully orchestrated the lunch under false pretenses, claiming she needed advice on how to tell her children she had been diagnosed with cancer—an illness Patterson was never actually diagnosed with.
The court heard that:
Patterson invited her estranged husband, Simon Patterson, to the lunch, but he declined to attend, citing discomfort.
The prosecution did not allege a clear motive, yet emphasized the calculated deception used to bring the victims together.
The prosecution argued that Patterson deliberately served the poisoned meal, knowingly introducing a deadly substance that caused irreversible liver damage in her unsuspecting guests.
Defense: A Tragic Accident, Not Murder
Patterson’s defense, led by Colin Mandy SC, maintained that the incident was a “terrible accident”, not a premeditated act of murder. The defense acknowledged that Patterson lied to police in the aftermath denying knowledge of foraging or mushroom preparation but argued that these lies were the result of panic and emotional distress, not malice.
The defense also:
Conceded that Patterson’s cancer claim was fabricated.
Stressed that no direct evidence proved Patterson’s intent to kill.
The defense portrayed Patterson as overwhelmed and deeply remorseful, challenging the jury to consider the absence of a clear motive.
The Verdict: Jury Reaches Unanimous Decision
After nearly a week of deliberations, the 12-person jury comprising seven men and five women returned unanimous verdicts on all four charges:
Guilty of three counts of murder.
Guilty of one count of attempted murder.
Throughout the reading of the verdicts, Erin Patterson remained composed, her gaze fixed ahead. Neither the Patterson nor Wilkinson families were present in court for the emotional conclusion to the trial.
The Judge’s Caution: Media Spotlight and Fair Trial
The trial, held at the Latrobe Valley Law Courts in Morwell, was conducted under intense national and global media scrutiny. Presiding Justice Beale issued repeated warnings to the jury to disregard media coverage and public opinion, underscoring the importance of basing their verdict solely on the evidence presented.
In his final instructions, Justice Beale reminded jurors:
The burden of proof rests entirely with the prosecution.
Patterson was under no obligation to prove her innocence.
A conviction required the jury to be satisfied beyond reasonable doubt not merely suspicion or probability.
National Impact and Public Reaction
The case has captivated public attention for over two years, sparking discussions about:
Food safety and foraging practices in Australia.
The complexities of intent and deception in criminal law.
The emotional and ethical weight of familial betrayal and violence.
The media frenzy surrounding the case dubbed by some as the “Mushroom Murder Trial” highlighted the challenges of high-profile trials in the age of social media, where public opinion can easily cloud legal proceedings.
What Happens Next?
Erin Patterson is expected to be formally sentenced in the coming weeks, with legal experts predicting a life sentence given the gravity of the charges. The sentencing phase may include victim impact statements and further examination of Patterson’s psychological state.
Conclusion: A Case That Will Be Remembered
The conviction of Erin Patterson closes a dark chapter in Australian legal history a case marked by tragedy, mystery, and profound loss. As the legal system delivers justice for the victims, the case will likely serve as a reference point for debates on criminal justice, public trust, and the dangers of deception within intimate family circles.
