Death Cap Mushroom Poisoning Kills Three, Hospitalizes Fourth in Victoria

Erin Patterson stands trial for the murder of three individuals and attempted murder of a fourth after allegedly serving beef Wellington laced with deadly death cap mushrooms at a lunch in Leongatha. The victims, Don and Gail Patterson and Gail's sister Heather Wilkinson, all died from acute liver failure consistent with death cap mushroom poisoning, while Heather's husband Ian Wilkinson survived but was critically ill and very close to death. Intensive care specialist Dr. Stephen Warrillow testified about the medical efforts to save the victims at Austin Health, including liver transplants and treatments like activated charcoal and vitamin C, noting the high mortality rates despite optimal care. Don Patterson underwent a liver transplant but his condition worsened, leading to his death, while Gail and Heather were too ill to receive transplants and died in the hospital. Ian Wilkinson's condition deteriorated significantly, requiring intubation and a laparoscopy, but he slowly improved and was eventually discharged to a rehabilitation facility. The prosecution alleges Patterson intentionally poisoned the meal, a charge she denies.
