Erin Patterson trial: Video evidence of mushroom cook’s daughter to continue

Alleged mushroom poisoner Erin Patterson’s young daughter told police she went to the cinema while her mother hosted lunch to discuss “adult stuff”, her triple-murder trial has heard.

A video of Erin Patterson’s young daughter being interviewed by police is being played to the alleged poisoner’s triple-murder trial.

About 30 minutes of the video, showing the child seated on a blue couch across from an interviewer, was displayed on multiple screens in the Latrobe Valley courthouse where the trial is being held on Thursday afternoon.

The remainder of the footage is expected to be played when Ms Patterson’s trial resumes on Friday morning.

She has pleaded not guilty to three counts of murder and one count of attempted murder, arguing the poisonings were an accident.

In the video, the girl is asked by a male police officer if she knows what they’re going to discuss.

“The lunch,” she replies.

“I wasn’t there so I don’t know what happened.”

As the video played, Ms Patterson appeared emotional, her face appearing to quiver and she could be seen to wipe her nose with a tissue at one point.

The nine-year-old told her interviewer her mum told her she would be going to see a movie with her older brother and another boy the morning of the lunch.

She said she saw “meat” in the oven and Ms Patterson was making a coffee as she explained she wanted to have lunch with her in-laws to discuss “adult stuff”.

“I don’t exactly know what they had but I know (brother) and me had leftovers the next day,” she said.

The young girl said she went to the cinema around midday on July 29, had McDonalds for lunch and was picked up by her dad Simon Patterson, whom she spent the evening with.

The following morning the girl said Ms Patterson told her she had diarrhoea and her “tummy felt sore”.

“The just needed to go to the toilet a lot and she felt sick,” she said.

“We were going to go to church but mum was too sick.”

Later that night, the girl said Ms Patterson told them they were having “leftovers” with meat, mashed potato and green beans served.

“She wasn't really hungry so (brother) ate the rest of hers,” she said.

The interviewer questioned how she knew this, with the girl responding; “she told us”.

Prosecutors allege the children’s meal was not contaminated with death cap mushrooms.

Simon Patterson’s parents, Don and Gail Patterson, and his aunt and uncle, Heather and Ian Wilkinson, fell ill after Ms Patterson served a beef Wellington dish at lunch on July 29, 2023.

Don, Gail and Heather died in hospital within a week, while Ian recovered after more than an month and a half in hospital.

At the start of the trial, Ms Patterson’s lawyer Colin Mandy SC said it was not disputed the meal contained death cap mushrooms but asserted his client did not intentionally nor deliberately poisoned the dish.

“The defence case is that what happened was a tragedy, a terrible accident,” he said.

The trial, before Justice Christopher Beale, continues.
