Erin Patterson, recently convicted of murdering three relatives by poisoning them with toxic mushrooms, also allegedly attempted to poison her estranged husband, Simon Patterson. In a court hearing, Simon Patterson detailed his suspicions of Erin's earlier poison attempts, identifying specific dishes including chicken korma curry, penne bolognese, and vegetable wraps that he believed made him seriously ill on several occasions. Despite feeling unwell after these meals, he never considered that others could be at risk until the tragic deaths of his family members following a meal at Erin's home, according to BBC and Reuters.

Details about the alleged poisoning attempts were previously suppressed but were disclosed after a judge lifted a gag order on the evidence during a hearing in August 2024. Simon Patterson had declined an invitation to lunch from Erin out of fear, testifying that he suspected he would be poisoned if he attended. He recounted keeping a spreadsheet of his illness linked to her cooking and noted past instances of severe health complications that required surgery, as described in reports from SCMP and Los Angeles Times.

The court had previously dropped the attempted murder charges related to Simon Patterson ahead of Erin’s trial, meaning the jury did not hear evidence regarding those specific allegations. Simon shared that on occasions when he and Erin were together on family trips, he would become ill after eating her meals, leading him to suspect poisoning rather than mere coincidence. His testimony highlighted a troubling pattern of illness that he connected to her cooking, leading to his eventual near-death experience, again referencing India Times and Channel News Asia.

The court is set to conduct hearings on August 25 to determine Erin Patterson's sentencing, where she could face life imprisonment for each murder. Additionally, many victim impact statements are expected to be presented during the proceedings. Erin’s defense maintains her innocence, claiming the fatal meal was an unfortunate accident, reflecting the complex dynamics of familial relationships and legal ramifications associated with the precarious situation, as outlined by CBS News and BBC.
