Gazeta Lodz - Australian triple-murder suspect allegedly cooked 'special' mushroom meal

On the opening day of a trial that has drawn global attention, Erin Patterson, 50, faced a jury accused of three murders -- including her parents-in-law -- and one attempted murder.

She has pleaded not guilty to all counts, with her defence saying it was all "a terrible accident".

Patterson "deliberately poisoned" her guests, Crown Prosecutor Nanette Rogers told the jury.

The accused served "individual beef Wellingtons, mashed potatoes and green beans", with the guests eating from four large grey dinner plates, while she ate from a smaller, orange plate, Rogers said.

Patterson invited her guests to the lunch in late July 2023 at her home in the sedate Victoria state farm village of Leongatha, telling them she had a health issue to relate, the prosecutor said.

Her estranged husband Simon Patterson declined, texting her the night before that he felt "uncomfortable" going.

In a return text minutes later, Patterson said she was "disappointed", as she wanted to prepare a "special meal and that she may not be able to have a lunch like this for some time", Rogers said.

But her husband's parents, Don and Gail Patterson, decided to go, along with his aunt Heather Wilkinson and her husband, local pastor Ian Wilkinson.

During the lunch, Patterson claimed to have cancer and wanted their advice about how to tell her two children, the prosecutor said.

Medical tests later found no evidence she had cancer, Rogers said.

Within hours of the lunch, the four guests developed diarrhoea and vomiting, and were raced to hospital.

All were diagnosed by treating doctors with poisoning by death cap mushrooms, Rogers told the court.

Within days, Don, Gail and Heather were dead.

- Guests dead within days -

Ian, the pastor, survived after nearly two months in hospital.

Patterson went to the hospital two days after the lunch and complained she, too, was unwell, the prosecution said.

She initially refused medical assistance and left the hospital, but relented and returned for treatment, the court heard.

Patterson said her children had eaten leftovers of the beef Wellington.

But she claimed to have scraped off the mushroom paste and pastry because they were "fussy", Rogers said.

When medical staff demanded to see her children, Patterson resisted saying she did not want them to "be panicked and stressed".

"She did not appear to be concerned about children's health but rather about stressing them out," Rogers said.

The children eventually received medical attention but did not have any symptoms of poisoning.

Rogers said Patterson knew that neither she nor her children had consumed the deadly mushrooms.

- 'Terrible accident' -

Police located beef Wellington remnants at Patterson's home, which were found under forensic investigation to have traces of death cap mushrooms, Rogers added.

Patterson allegedly told doctors she used fresh mushrooms from a supermarket and also dried mushrooms from an Asian grocery –- but she did not remember which one.

A Department of Health investigation was unable to trace any shop selling death cap mushrooms.

Patterson discarded a food dehydrator in the days after the lunch, which was later found to contain traces of death cap mushrooms, prosecutors said.

Patterson's lawyer Colin Mandy said the poisoning was a "tragedy and terrible accident".

"She didn't do it deliberately, she didn't do it intentionally. The defence case is that she didn't intend to cause anyone any harm on that day," he said.

Patterson is being tried in the Latrobe Valley Law Courts in Morwell, south of Melbourne.

The trial is expected to last about six weeks.
