The alleged ‘Mushroom Murder’ Saga: Everything you need to know

Updated 7th July, 2025

BREAKING: Erin Patterson found guilty of three counts of murder.

KEY DETAILS from today’s verdict:

A Supreme Court jury has found Erin Patterson guilty of murdering three relatives by deliberately lacing a beef Wellington lunch with death cap mushrooms.

Patterson had pleaded not guilty to murder and attempted murder, telling the court the poisonous mushrooms were accidentally included in the meals she served to four relatives in 2023.

The jury of seven men and five women took seven days to reach their verdict following a trial in the town of Morwell, in south-east Victoria, that lasted about nine weeks.

Patterson’s parents-in-law Don and Gail Patterson both died after the Leongatha lunch, along with Gail’s sister Heather Wilkinson. Heather’s husband Ian Wilkinson survived after spending weeks in the hospital.

Sitting in Morwell, the Supreme Court jury found Patterson guilty of murdering Don, Gail and Heather and guilty of the attempted murder of Ian.

As the verdict was handed down, Patterson did not express any obvious outward emotion, watching the process from inside the courtroom.

Prosecutions Case:

Crown prosecutor Nanette Rogers SC told the jury that Erin Patterson deliberately poisoned her lunch guests by mixing lethal death cap mushrooms in the individual beef Wellington portions she served them.

Prosecutors alleged Patterson engaged in four substantial acts of deception to carry out her crimes:

• Fabricated Illness to Lure Guests: Prosecutors asserted that Patterson falsely claimed to have cancer in order to invite her guests to lunch at her home. This fabricated diagnosis also served as a convenient pretext to ensure her own children were not present during the meal.
• Premeditated Poisoning of In-Laws: It was alleged that Patterson executed a “sinister deception” by using what appeared to be a wholesome, home-cooked meal to administer a lethal dose of toxic mushrooms to her in-laws. Prosecutors contended that she intentionally prepared individual beef Wellingtons, served on separate plates, to avoid ingesting the poison herself.
• Faking Illness to Avoid Suspicion: From approximately 4 p.m. on the day of the lunch, Patterson reportedly claimed to be unwell. Prosecutors argued that this was a ruse to deflect suspicion. Notably, her symptoms differed from those of her guests, whose delayed onset of illness first led medical personnel to suspect death cap mushroom poisoning.
• Ongoing Efforts to Conceal the Truth: Prosecutors further alleged that Patterson engaged in a prolonged effort to obscure the facts surrounding the lunch. According to expert testimony, she misled investigators by lying about feeding the leftovers to her children, providing false information about the source of the mushrooms, denying ownership of a food dehydrator, and hiding her primary mobile phone from authorities.

What happens next?

She will be remanded in custody to a later date, when both the prosecution and defence legal teams will make submissions to Justice Beale about what they think the sentence should be.

This is called a plea hearing.

The sentencing itself would then be adjourned to a later date or a date that is yet to be set.

Erin Patterson has been charged with three counts of murder and five counts of attempted murder following a lunch at her home. Patterson had invited over her ex-in-laws, Don and Gail Patterson, Gail’s sister Heather Wilkinson, and Gail’s husband Ian, to enjoy a home cooked meal that ended in disaster. Her ex-husband was also invited to the lunch but was unable to attend.

Patterson has been accused of lacing the beef Wellington with poisonous mushrooms which killed Don, Gail and Heather and left the other attendees seriously unwell. The Police have alleged that the symptoms of the victims were consistent with mushroom poisoning and noted that the event took place after there was an advisory warning released to not forage or consume wild mushrooms unless you had the expertise to do so.

Patterson maintains her innocence and states that she prepared the meal using fresh mushrooms from the local supermarket and dried mushrooms from an Asian grocer in Melbourne. Ms Patterson also consumed the beef Wellington and was hospitalised however, quickly recovered from the illness.

Police note that following Ms Patterson’s lunch, she disposed of a food dehydrator at a local skip which has been recovered as evidence in the case.

Court documents that have recently been released to the media suggest that Ms Patterson had attempted to murder her former partner four times prior to the lunch between November of 2021 and July of 2023.

Media Involvement in Mushroom Murder Case

The justice system and the media often interact in various capacities however, the coverage of the alleged ‘mushroom murders’ has been relentless and brought the media limelight to the small rule town in Victoria. As a result, the investigation of the alleged murder has been under intense public scrutiny.

A potential danger with the media coverage that is experienced in high profile cases is that it may negatively influence the fairness of the trial. Due to the public heavily relying on the media to convey information, the information that is published may influence the public’s attitude towards the accused before they have even entered the courtroom. Therefore, media scrutiny may jeopardise the foundational pillar of the criminal justice system being that the accused is innocent until proven otherwise.

It must be noted that jurors must remain independent and unbiased. However, given the wide range of sources available covering the infamous ‘death cap murders’, jurors may be inclined to research details of the trial that have not been provided within the courtroom. This may influence their decision-making as their deliberation may be based on evidence that has been intentionally excluded from the trial for various legal reasons. In these instances, jurors may receive a direction that they are to try to suppress any information that has been acquired prior to the trial and be conscious of how this information may influence their deliberation.

It is important to note that the role of the juror is not to be present for legal arguments, i.e., whether certain evidence should or should not be adduced, but rather to acknowledge the evidence that is put forward and deliberate according to that evidence.
