Patterson’s former in-laws, Don and Gail Patterson, 70, and Gail’s sister Heather Wilkinson, 66, all died in hospital, days after the meal. Wilkinson’s husband Ian spent two months in hospital recovering, but survived. He gave evidence during the trial.
Patterson had pleaded not guilty and had always maintained the deaths were a tragic accident.

The prosecution accused Erin Patterson of telling a series of lies to police, including that she did not forage for mushrooms in the meal and did not own a dehydrator.
She revealed for the first time that she enjoyed foraging for wild mushrooms when she was in the witness box, admitting she started foraging in 2020 during the pandemic.
