Below is a chronological breakdown of the key dates, individuals, and formal allegations that constitute the official record of the case thus far.
What Happened at the July 29th Lunch?
The focal point of the case is a lunch that took place at Erin Patterson’s home in Leongatha, a town southeast of Melbourne. The meal was reportedly part of an effort at reconciliation with her estranged husband, Simon Patterson, who was invited but did not attend at the last minute.
The guests included Simon’s parents, Don and Gail Patterson, and Gail’s sister, Heather Wilkinson, with her husband, Ian Wilkinson. Erin Patterson’s two children were also present but reportedly ate a different meal and did not fall ill. Prosecutors allege the four adult guests were served a beef Wellington pie that contained death cap mushrooms (Amanita phalloides), which are highly toxic and responsible for the majority of fatal mushroom poisonings worldwide.
A Timeline of Illness, Death, and Investigation
Following the lunch, all four guests became critically ill. They were hospitalized on July 30 with what was initially believed to be severe gastroenteritis. The situation quickly escalated as their symptoms were identified as consistent with poisoning by death cap mushrooms.
- August 4: Gail Patterson and Heather Wilkinson die in the hospital.
- August 5: Don Patterson dies in the hospital.
- September 22: Ian Wilkinson is released from the hospital after nearly two months of treatment.
- November 2: Victoria Police arrest Erin Patterson at her Leongatha home. Police are seen searching the property.
- November 3: Patterson is charged with three counts of murder and two counts of attempted murder. Police later add three more charges of attempted murder related to her estranged husband.
The investigation included a search of a local waste facility where police located a food dehydrator, which they allege Patterson used to prepare the mushrooms.
The Specific Charges Erin Patterson Faces
Erin Patterson is facing a total of eight charges. She has pleaded not guilty to all of them and is scheduled to stand trial. The charges are:
- Three counts of murder for the deaths of Don Patterson, Gail Patterson, and Heather Wilkinson.
- Five counts of attempted murder. One count is for Ian Wilkinson. The other four counts relate to her estranged husband, Simon Patterson, for alleged attempts on his life on four separate occasions between November 2021 and May 2022.
Patterson has publicly denied any wrongdoing. In a written statement provided to police before her arrest, she claimed she purchased the mushrooms from an Asian grocery store and was herself hospitalized with stomach pains after the meal. The case is proceeding through the Australian court system, with a trial expected to provide further details from both the prosecution and the defense.
A Case Proceeding to Trial
With Erin Patterson’s not guilty plea formally entered, the case is now set to proceed through the Australian judicial system. The forthcoming trial is expected to present detailed evidence and arguments from both the prosecution and the defense, moving beyond initial allegations. As the legal proceedings unfold, the established facts of the case will be supplemented by official testimony, and continued reporting will adhere strictly to the verifiable information presented in court.
