Accused Woman Claims Toxic Meal Was Tragic Accident in Court Testimony
Erin Patterson takes the stand, alleging she too suffered from the fatal mushroom lunch served to her guests, emphasizing her struggle with bulimia.
An Australian woman on trial for murder has claimed she vomited after consuming part of the toxic mushroom meal that led to the deaths of three of her relatives. Erin Patterson, who has pleaded not guilty to three counts of murder and one count of attempted murder, insists the fatal lunch served to her guests in July 2023 was a tragic mishap.
During her testimony in Victoria's Supreme Court, Patterson argued that while she did serve beef Wellington—which allegedly contained poisonous death cap mushrooms—she did not intend to harm anyone. She alleged that the contaminated dish made her sick too. On day three of her testimony, she revealed that she had consumed primarily dessert, eating a large portion of cake before becoming ill.
The prosecution claims Patterson deliberately poisoned her guests, but her defense attorneys suggested the mushroom mix-up was unintentional. They highlighted Patterson's admission of previously misrepresenting her health to entice her guests, previously claiming a cancer diagnosis instead of being embarrassed about weight-loss surgery.
The fatal meal took the lives of Don and Gail Patterson, both 70, and Gail's sister, 66-year-old Heather Wilkinson, while pastor Ian Wilkinson was the only survivor after extensive medical intervention.
The trial has garnered significant media attention, with over 50 witnesses interviewed. Patterson described the detailed preparation of the lunch and her fond memories of beef Wellington from her childhood. She emotionally reflected on her cooking process, where she experimented with dried mushrooms from her pantry—an act she now thinks might have included dangerous foraged varieties.
As the trials continue, Patterson’s struggle with bulimia emerged as a significant aspect of her narrative. She acknowledged a long-term pattern of binge eating and vomiting, complicating the story as she tried to clarify her actions and intentions during the fateful lunch.
