Freshly unsealed records outline Erin Patterson husband poisoning allegations from 2021 and 2022. She allegedly served Simon Patterson pasta, chicken curry, and a sandwich wrap. Each meal, he claims, made him severely ill.
Simon also accused her of giving him cookies she said their daughter baked. He suspected the cookies contained antifreeze.
One illness left Simon in a coma. His family twice prepared to say goodbye.
Simon’s Suspicions and Evidence
Simon kept a log of symptoms after meals Erin prepared but did not eat. He shared his concerns with Dr Christopher Ford.
Police later discovered a file on Erin’s computer about barium carbonate, a chemical used in rat poison. An expert said one illness matched barium carbonate poisoning.
Simon kept food samples for possible testing. He also changed his medical power of attorney from Erin to his father, Don.
Why the Jury Never Heard the Claims
The Erin Patterson husband poisoning allegations did not reach jurors. Prosecutors dropped three attempted murder charges involving Simon before the trial began.
A judge separated the “Simon charges” from the “lunch charges.” That decision blocked evidence such as poison research and Don Patterson’s jar of vomit.
Convictions in the Mushroom Case
In July 2025, a jury convicted Erin Patterson of murdering Don and Gail Patterson and Heather Wilkinson. The court also found her guilty of attempting to murder Ian Wilkinson.
Prosecutors said she cooked a beef Wellington containing death-cap mushrooms at her Leongatha home in July 2023. Simon declined her invitation, believing he was the only target.
Patterson denies intending harm. She remains in custody and will face sentencing on 25 August 2025.
Pattern of Alleged Behaviour
The earlier Erin Patterson husband poisoning claims suggest she repeatedly targeted her husband through food. Prosecutors said she controlled meal preparation in each alleged incident.
The mix of hidden evidence, fatal mushrooms, and earlier suspected poisonings ensures the case stays in headlines worldwide.
