A woman in Australia was found guilty of murdering her in-laws by poisoning them with deathcap mushrooms, which were reportedly hidden in a beef Wellington. Erin Patterson, 50, was convicted in July of the murders, as well as the attempted murder of a fourth person who survived after undergoing a liver transplant.

Key Takeaways:

• Patterson was found guilty of murdering her husband's parents and aunt by lacing their lunch with lethal deathcap mushrooms in 2023.
• Prosecutors initially sought to present evidence that she may have laced rat poison into a meal prepared for Simon Patterson, her estranged husband, to whom she had previously attempted to poison with curries, sandwiches, and biscuits.
• Simon had become so concerned of falling ill from meals prepared by Patterson that he kept an Excel spreadsheet on his computer to document them.
• Patterson was accused of a calculated campaign to kill her estranged husband, including poisoning his lunch with allegedly lethal barium carbonate, which the prosecution argued could be consistent with rat poison.
• Forensic testing revealed that Patterson owned a food dehydrator containing traces of the deathcap mushrooms.
• Patterson told police that she did not own a food dehydrator, and an article about barium carbonate was found on her computer, along with a social media post asking for advice on treating her cat after it ate poisonous mushrooms (although she did not own a cat).
• Simon had previously told relatives that he feared his estranged wife was trying to kill him after a series of unexplained medical crises between 2021 and 2022.

Statistics:

• Patterson was found guilty of murdering three people and attempting to murder a fourth.
• Patterson was accused of attempting to poison her estranged husband at least four times between 2021 and 2023.
• Simon Patterson reported three near-death experiences between 2021 and 2022, including one incident in May 2022 where he fell into a coma after eating a chicken korma curry prepared by Patterson.
