SYDNEY - An Australian woman accused of murdering her in-laws with a toxic mushroom-laced beef Wellington will face the court in May, a magistrate ruled on April 22.

Erin Patterson faces three counts of murder for allegedly cooking up a poisonous meal in July 2023 that killed her parents-in-law and the wife of a local pastor.

The 49-year-old is also accused of attempting to kill her estranged husband four times.

Magistrate Tim Walsh ordered that she appear on May 7 for a “committal mention”, part of the legal process for sending a person to trial.

Patterson appeared in Latrobe Valley Magistrates Court by video link from a small room in jail, wearing spectacles and a zip-up blue prison jersey, with her hair in a short ponytail.

She appeared calm, speaking only briefly to say she could hear the magistrate and to confirm who was representing her legally in the hearing.

Police have previously suggested the meal she served included death cap mushrooms.

Patterson allegedly cooked the beef Wellington in late July, serving her estranged parents-in-law Don and Gail Patterson, both 70, as well as local Baptist pastor Ian Wilkinson, 69, and his wife Heather, 66.

The two couples allegedly started experiencing food poisoning symptoms later that night and, with their health rapidly deteriorating, they sought the help of doctors at local hospitals.

The Pattersons and Mrs Wilkinson died in the days following the lunch, while Mr Wilkinson eventually recovered after spending nearly two months in hospital.

Police said Patterson’s husband, Mr Simon Patterson, “became ill after meals” on separate occasions in 2021 and 2022, and charged the wife with four counts of attempted murder. AFP
