Introduction to the Trial

The Australian host of a weekend family lunch is on trial charged with murdering her estranged husband’s parents and an aunt and attempting to murder an uncle with poisonous mushrooms.

Prosecutor Nanette Rogers opened her case on Wednesday against Erin Patterson, 50, in the Victoria state Supreme Court. Patterson has pleaded not guilty to all charges.

The Day of the Lunch

She served meals of beef Wellington, mashed potato and green beans at her home in the rural town of Leongartha on July 29, 2023. Her guests included her parents-in-law Gail and Don Patterson, both 70, Gail Patterson’s sister Heather Wilkinson, 66, and Wilkinson’s husband, Ian Wilkinson, 68.

The Poisoning

All four guests were hospitalized the next day with poisoning from death cap mushrooms, also known as amanita phalloides, that were added to the beef and pastry dish. Ian Wilkinson survived after a liver transplant.

Background

Erin Patterson’s husband, Simon Patterson, 50, was also invited to the lunch but declined. Two weeks before the poisoning, Erin Patterson had invited her husband and his relatives to lunch while she was attending a Korumburra Baptist Church service where Ian Wilkinson was the pastor. Simon Patterson initially accepted the invitation.

Attempted Murder Charges Dropped

The jury was told on Tuesday that prosecutors had dropped three charges that Erin Patterson had attempted to murder her husband, whom she had been separated from since 2015.
“ She said the purpose of the lunch was to discuss some medical issues that she had and to get advice about how to break it to the kids,” Rogers said.
“The accused said that it was important that the children were not present for the lunch,” Rogers added.

Lunch Guest Puzzled by Host’s Plate

When Heather Wilkinson was taken to the hospital the next morning, she told Simon Patterson she had been puzzled by Erin Patterson eating from a different plate than those served to the guests.
“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,” said Heather Wilkinson, according to the prosecution.
Simon Patterson told his aunt that his wife might have run out of plates.

Defense Lawyer’s Statement

Defense lawyer Colin Mandy told the jury his client never had cancer and that the guests had been poisoned by mushrooms she had served, but that the poisoning was accidental.
“The defense case is what happened was a tragedy. A terrible accident,” Mandy said.
Rogers told the jurors that she she would not provide a motive for the poisonings.
“You might be wondering now why would the accused do this? What is the motive? You might still be wondering this at the end of this trial,” Rogers said. “You do not have to be satisfied what the motive was or even that there was a motive."

Defendant’s Actions After the Lunch

Two days after the lunch, Erin Patterson went to the hospital complaining of diarrhea and nausea. By then, medical staff had diagnosed her guests as suffering death cap poisoning.
Erin Patterson told authorities that she had cooked with a mixture of fresh mushrooms bought from a supermarket and dried mushrooms bought from an Asian food store.

Defendant’s Foraging for Mushrooms

Mandy said his client had lied to police when she said she hadn’t foraged for wild mushrooms.
“She did forage for mushrooms. Just so that we make that clear, she denies that she ever deliberately sought out death cap mushrooms,” Mandy said.

Conclusion

The trial was adjourned until Thursday and is expected to continue for six weeks. She is charged with three counts of murder and one of attempted murder. Murder carries a maximum penalty of life imprisonment and attempted murder carries a maximum 25 years in prison.
