An Australian jury on Monday convicted home cook Erin Patterson, 50, of three counts of murder and one count of attempted murder after a 10-week trial at the Supreme Court of Victoria in Morwell. She faces a maximum sentence of life in prison, with the court to set a sentencing date later. Prosecutors said Patterson deliberately laced individual servings of beef Wellington with deadly death-cap mushrooms during a family lunch at her Leongatha home on 29 July 2023. Her former parents-in-law Don and Gail Patterson, both 70, and Gail’s sister Heather Wilkinson, 66, died within a week of eating the meal; Heather’s husband, Reverend Ian Wilkinson, survived after weeks in hospital. Patterson’s estranged husband, Simon Patterson, had been invited but declined the lunch. The prosecution argued Patterson fabricated a cancer diagnosis to lure her guests, served herself an untainted portion and later attempted to destroy evidence. Patterson maintained the poisonings were an accident, but after roughly six days of deliberation the 12-member jury rejected her testimony. The verdict caps a case that has drawn intense local and international attention, and the court will reconvene for sentencing in the coming weeks.
