Erin Patterson, the Australian woman accused of killing three relatives with a meal of death cap mushrooms baked in a Beef Wellington lunch, has been found guilty of three counts of murder and the attempted murder of the lone survivor.

A 12-member jury reached the verdict after around six days of deliberation following a 10-week trial in Morwell, a tiny town about an hour’s drive from the suburban dining room in Leongatha, Victoria, where the lethal lunch was served in July 2023.

Dozens of media crews raced to the court when it was announced the jury had reached a verdict in the case that has captivated audiences worldwide and spawned four podcasts dedicated to unpacking each day’s evidence.

During weeks of testimony, Patterson was accused of deliberately tainting the lunch with death cap mushrooms, highly toxic fungi that she picked after seeing their location posted on a public website.

In the days after, her former parents-in-law, Don and Gail Patterson, died along with Gail’s sister Heather Wilkinson. Heather’s husband Ian, their local pastor, survived after a weekslong stay in hospital.

Her defense lawyers had argued the deaths were a “terrible accident” that occurred when Patterson tried to improve the taste of the meal, and that she repeatedly lied to police out of panic when she realized she may have added foraged mushrooms to the mix.

Patterson sat in court, listening as prosecutors called witness after witness, whose testimony, they alleged, told a compelling story of a triple murder that the jury ultimately found satisfied the legal standard of beyond reasonable doubt.

Under Australian law, none of the jurors can be publicly identified, and they’re prohibited from disclosing jury room deliberations even after the trial ends.

It will never be known which pieces of evidence influenced each juror’s decision, but all 12 were required to agree on the verdict.

The agreed facts were that Patterson asked five people to lunch on July 29, 2023, including her estranged husband Simon Patterson, who pulled out the day before.

Within hours of the meal, the four lunch guests – Simon’s parents Don and Gail, and his aunt and uncle, Heather and Ian Wilkinson – became ill with vomiting and diarrhea. They went to hospital where they were placed in induced comas as doctors tried to save them.

Gail and Heather died on August 4 from multiorgan failure, followed by Don on August 5, after he failed to respond to a liver transplant. Ian Wilkinson survived and was finally discharged from hospital in late September, after almost two months of intensive treatment.

Death cap mushrooms contain amanita toxins that prevent the production of proteins in liver cells, leading to cell death and possible liver failure from about two days after ingestion.

Native to Europe, the lethal mushrooms have been found growing in several Australian states, and around the time of the lunch, they had been seen within a short drive of Patterson’s home in rural Victoria.

During the trial, the prosecution argued that Patterson had the opportunity to pick lethal mushrooms after seeing their location posted on the citizen science iNaturalist website.

The guilty verdict suggests the jury accepted the prosecution’s argument that she likely traveled to two sites in April and May 2023, and deliberately picked the mushrooms used in the meal.

Prosecutor Nanette Rogers SC alleged that “four calculated deceptions” were at the heart of the case. “The first deception was the fabricated cancer claim she used as a pretence for the lunch invitation,” she said.

“The second deception was the lethal doses of poison the accused secreted in the homecooked beef Wellingtons. The third deception was her attempts to make it seem that she also suffered death cap mushroom poisoning and the fourth deception, the sustained cover-up she embarked upon to conceal the truth.”

Patterson admitted that on April 28 – the same day as cellphone signals put her in the vicinity of death cap mushrooms – she bought a dehydrator that she later dumped at a waste recycling center on August 2, as her guests lay in hospital.

It had her fingerprints on it and contained remnants of death cap mushrooms.

The prosecution alleged that Patterson faked illness in the days after serving the lunch and tried to cover her tracks by disposing of the dehydrator and factory resetting her devices to delete evidence.

Patterson’s defense lawyer Colin Mandy SC accused the prosecution of being selective with the evidence and pushing “four ridiculous, convoluted propositions.”

The first was that Patterson would do this “without any motive,” Mandy said.

He said there were several reasons why Patterson would not want to kill her guests. She had no money issues, lived in a big house, and had almost full-time custody of her two young children, who were very close to their grandparents, he said.

The prosecution did not have to prove motive.

Rogers accused Patterson of having two faces: One she showed the world that suggested she had a good relationship with the Pattersons, and a hidden face she showed only her Facebook friends that suggested she wanted “nothing to do with them.”

In Facebook messages sent in December 2022, Patterson had expressed anger and frustration over Don and Gail’s reluctance to get involved in their son’s marriage breakdown.

“I’m sick of this shit I want nothing to do with them,” she wrote. “I thought his parents would want him to do the right thing but it seems their concern about not wanting to feel uncomfortable and not wanting to get involved in their son’s personal matters are overriding that so f*** em.”

And another message read: “This family I swear to f***ing god.”

During eight days of testimony including cross-examination, Patterson consistently pleaded her innocence, claiming she inadvertently added foraged mushrooms to the meal.

In his directions to the jury, Justice Christopher Beale said that Patterson’s admission that she told lies and disposed of evidence must not cause them to be prejudiced against her.

“This is a court of law, not a court of morals,” he said.

“The issue is not whether she is in some sense responsible for the tragic consequences of the lunch, but whether the prosecution has proved beyond a reasonable doubt that she is criminally responsible for those consequences,” he said.

The jury found that Patterson had intended to kill all four lunch guests and lied repeatedly on the stand to claim she didn’t.

Patterson will be sentenced at a later date.

As an Australian following along, this was the most obvious criminal murder verdict of all time. This woman is possibly one of the stupidest people alive, and was too stupid to realise how obvious she was and thought she could win at trial.

Not terribly surprising, her side of the story made no sense
