Erin Patterson, 50, has pleaded not guilty to all charges, with CNN reporting that her defence team maintains the incident was a tragic accident.
However, the prosecution is building a case against her, arguing that Patterson carefully planned the lunch to harm her ex-husband’s kin.
Did Patterson cook with deadly mushrooms?
Patterson, who faces three murder charges and two counts of attempted murder, emotionally testified before the Supreme Court in Victoria, stating she had no idea the mushrooms she added to her beef Wellington dish were poisonous.
The deaths of Don and Gail Patterson, both aged 70, and Gail’s sister Heather Wilkinson, 66, shocked Leongatha after they died days after sharing lunch at Erin’s home in July 2023.
Ian Wilkinson, Heather’s husband, was the sole survivor of the group and spent weeks hospitalised.
A report by CBS News revealed that Patterson broke down in court as she admitted to lying about her health to her estranged husband's relatives to get them to attend the lunch.
The mum of two confessed that she falsely told the family she had cancer, a lie that she stated that she deeply regrets.
"I didn’t want to tell anyone I was planning weight loss surgery. I felt ashamed and thought pretending I had cancer would explain why I looked unwell. But I shouldn’t have lied," she said tearfully.
Why did Patterson mislead police after the deaths
Patterson also admitted to misleading investigators initially, saying she feared losing her children and being unfairly blamed for the deaths.
This included denying mushroom foraging and lying about owning a dehydrator, a device that could dry mushrooms, including the wild ones she collected during walks.
During cross-examination, Patterson explained she intended to prepare a special meal and had splurged on top-grade ingredients.
She used mushrooms from her pantry, a mix of store-bought and possibly foraged ones.
"I thought they were all store-bought. But now I think there was a possibility there were foraged ones in there too," she said.
She acknowledged that she dehydrated some wild mushrooms weeks earlier and may have unknowingly mixed them into the container used for the dish.
Patterson said the mushrooms looked and smelled unusual, and some came from an Asian grocer in Melbourne, describing their odour as pungent.
Why do prosecutors believe Patterson planned poisoning
Prosecutors argued that Patterson intentionally poisoned the guests, pointing out that she did not eat much of the beef Wellington herself and began vomiting after bingeing on cake, which might have helped her expel the toxins.
She later developed mild diarrhoea and recovered quickly compared to her guests.
Adding to the suspicion, she remotely wiped her mobile phone after police seized it, allegedly to delete photos of mushrooms she had foraged.
She also got rid of the dehydrator and told authorities she never owned one.

Her estranged husband, Simon Patterson, who had been invited to the lunch but chose not to attend, reportedly confronted her at the hospital, asking if she'd poisoned his parents.
The court also heard details about Patterson’s rocky relationship with her in-laws and Simon.
She said her relationship with Don and Gail never changed, even after formally separating from Simon in 2015.
However, messages presented in court revealed moments of frustration and hurt, particularly around family disagreements and child support.
Despite the separation, Patterson kept Simon’s name on the title of her property, hoping it would serve as a gesture to reunite their family.
