The trial of Erin Patterson, an Australian woman accused of murdering three elderly relatives of her estranged husband by serving them poisonous mushrooms in a beef Wellington lunch, has entered its final stages. After a marathon nine-week trial, the defense concluded its case, arguing that Patterson was ill following the fatal meal. The judge instructed the jury to disregard certain prosecution arguments and warned them against letting sympathy influence their judgment. The jury retired on June 30, 2025, to begin deliberations on Patterson's fate. Deliberations have extended over multiple days, with the jury considering the 'ultimate issue' of intent in the triple murder case. The estranged husband had been invited to the lunch but withdrew the day before. The case has drawn widespread attention in Australia and internationally as the jury continues to weigh the evidence presented during the lengthy trial.
