An Australian woman convicted of poisoning three elderly relatives with death cap mushrooms was sentenced on Monday to a term that carries a minimum non-parole period of 33 years.
Erin Patterson, 50, was found guilty in July of murdering Gail Patterson, Donald Patterson and Heather Wilkinson and guilty of the attempted murder of Ian Wilkinson, who survived the July 2023 meal at Patterson's home in Leongatha, a town about 135 kilometres southeast of Melbourne. Justice Christopher Beale said the planning behind the killings and Patterson's lack of remorse warranted a lengthy sentence and noted the harms extended beyond the direct victims to their extended families and Patterson's children.
“Not only did you cut short three lives and cause lasting damage to Ian Wilkinson’s health, thereby devastating the extended Patterson and Wilkinson families, you inflicted untold suffering on your own children, whom you robbed of their beloved grandparents,” Beale said during the sentencing hearing in the Supreme Court of Victoria in Melbourne. Including time already served, Patterson will be 81 before she can be considered for release.
A jury convicted Patterson after a 10-week trial that attracted global media attention and intense local interest. The prosecution argued the meals served to the family on the day in July 2023 were deliberately laced with Amanita phalloides, commonly called death cap mushrooms. Patterson has maintained her innocence throughout the proceedings and told the court the poisonings were accidental.
The jury also found Patterson guilty of attempting to murder Ian Wilkinson, Heather Wilkinson's husband, who survived after receiving medical treatment. Outside court after the sentencing, Ian Wilkinson thanked police, prosecutors and medical teams for bringing the case to trial and for the care he and others received. “We’re thankful that when things go wrong, there are good people and services and systems available to help us recover,” he said.
Prison conditions and pre-sentencing submissions were raised during the hearing. Patterson's lawyer had urged the judge to impose a sentence with a non-parole period, arguing Patterson's notoriety would make incarceration more onerous. A corrections officer told the court Patterson had been kept in isolation for her own safety and had contact with only one other prisoner. Beale said he took that isolation into account in fixing the sentence and acknowledged there was a substantial chance Patterson would remain in solitary confinement for years.
The prosecution urged that Patterson should never be released. Patterson has 28 days to file an appeal against the conviction or the sentence but had not indicated whether she would do so as of Monday.
The deaths devastated the close-knit communities of Leongatha and nearby Korumburra, and the court received 28 victim impact statements, seven of which were read publicly during pre-sentencing hearings. Ian Wilkinson told the court last month that the death of his wife had left him bereft. “It’s a truly horrible thought to live with that somebody could decide to take her life. I only feel half alive without her,” he said, breaking down in tears as he delivered his statement.
The case generated extraordinary media interest in Australia and abroad. Journalists and television crews descended on the region when the trial began in April, and several daily podcasts drew millions of Australian listeners. For the first time in its history the Supreme Court allowed a television camera into the courtroom to broadcast sentencing remarks live because of overwhelming public interest.
The trial has prompted books, documentaries and a forthcoming drama series titled "Toxic" slated to air on the Australian Broadcasting Corporation. The sentences imposed on Monday and the questions surrounding motive and method are likely to remain the subject of scrutiny as family members and the wider community continue to process the deaths and their aftermath.
Patterson was escorted from the courtroom after the sentence was handed down. The court's determination reflected its finding that the offences were deliberate, meticulously planned and had long-lasting consequences for the victims and their families, the judge said.
