Australian judge sentences Erin Patterson to life in prison for poisoning relatives with mushrooms

An Australian judge on Monday (September 8, 2025) sentenced triple-murderer Erin Patterson to life in prison with a non-parole period of 33 years for poisoning four of her estranged husband’s relatives with death cap mushrooms.

Justice Christopher Beale told the Victoria State Supreme Court that Patterson’s crimes involved an enormous betrayal of trust.

Patterson was convicted in July of murdering Don and Gail Patterson and Gail’s sister, Heather Wilkinson, with a lunch of beef Wellington pastries laced with foraged death cap mushrooms.
