Australian woman Erin Patterson guilty of mushroom murders: All to know

A jury in Australia on Monday found a woman guilty of murdering her estranged husband’s parents and aunt using poisonous mushroom-laced beef Wellington, its verdict capping weeks of courtroom depositions in a case that has gripped the country and made headlines worldwide.

Erin Patterson, the convict, had denied the charges, and her defence team had called the deaths a “terrible accident”.

On July 29, 2023, Patterson hosted her former in-laws for lunch at her home in Leongatha, a town 135km (84 miles) southeast of Melbourne, in the southeastern Australian state of Victoria.

Her guests included her mother-in-law, Gail Patterson; father-in-law, Donald Patterson; Gail’s sister, Heather Wilkinson; and Heather’s husband, Ian Wilkinson. Her estranged husband, Simon Patterson, declined the invitation.

Patterson, now 50 years old, served her guests individual beef Wellingtons, a baked steak dish where beef tenderloin is wrapped in a mushroom paste and puff pastry, with mashed potato and green beans on the side. Patterson ate beef Wellington, too.

All four of the guests fell sick within hours of eating the meal and were hospitalised. Gail, Donald, and Heather passed away, while Ian survived after spending weeks in an induced coma. Gail and Donald were both aged 70 at the time of their deaths, while Heather was 66 years old. Patterson’s lawyers argued that she also fell sick after lunch and presented her medical test results as evidence. It was later found out that the Wellingtons were laced with poisonous death cap mushrooms.

 

Prosecutors said Patterson was separated from Simon, but the two had remained amicable afterwards. Patterson had two children with Simon, who were also present at the house during the lunch, but did not eat the Wellingtons.

Patterson was arrested in November 2023 and has been in custody ever since. She was charged with the murders of Gail, Donald and Heather, alongside the attempted murder of Ian. These charges carry a life sentence.
