Simon Patterson’s memoir on Erin Patterson’s triple murder case and appeals
Consensus Summary
Simon Patterson, the estranged husband of convicted triple murderer Erin Patterson, is writing a memoir about the case, which involved the poisoning deaths of his parents, Don and Gail Patterson, and his aunt Heather Wilkinson, as well as the attempted murder of Heather’s husband, Ian Wilkinson. The murders occurred in July 2023 after Erin Patterson served a fatal mushroom-laced lunch. Erin Patterson was sentenced to life in prison with a 33-year non-parole period, though both her conviction and sentence are under appeal. Simon Patterson’s allegations of being poisoned by Erin were dropped from the trial, and he has remained publicly silent through his spokesperson, Jessica O’Donnell. The memoir’s release will be delayed until the appeals conclude, with a publisher deal already secured but details yet to be announced. O’Donnell, who managed media relations during the trial, described the case as unprecedented in scale, handling hundreds of daily inquiries at its peak.
