Prosecutors to review sentence for Erin Patterson after life term for deaths from death-cap mushrooms

The Director of Public Prosecutions in Victoria is reviewing the sentence handed to Erin Patterson, who was convicted of the murders of three relatives after they ate death‑cap mushrooms served at a family lunch in 2023.

Patterson, 50, was sentenced last week to life imprisonment with a non‑parole period of 33 years by Justice Christopher Beale. Prosecutors have said they are considering an appeal to extend the minimum term, and both the DPP and Patterson have 28 days from sentencing to lodge appeals.

Patterson was found guilty of the murders of her in‑laws, Don and Gail Patterson, and Gail's sister, Heather Wilkinson. The three died after consuming beef Wellingtons containing death‑cap mushrooms at Patterson's home in Leongatha on July 29, 2023. A fourth attendee, Pastor Ian Wilkinson, survived; Patterson was also convicted of his attempted murder. She had pleaded not guilty to the charges.

Crown prosecutors had urged a harsher penalty. During sentencing submissions, Crown prosecutor Jane Warren argued Patterson's conduct fell into the "worst" category of offending and urged that she be jailed for life without the possibility of parole, saying the victims suffered a "slow and painful death." Justice Beale told the court he accepted that Patterson had meticulously planned the meal and had acted with the intention of killing her relatives. "Your failure to show any remorse pours salt into your victims' wounds," he said.

Under Victorian law, a 25‑year minimum term is considered a life sentence. At the non‑parole date of 33 years, Patterson will be 83 years old. A spokeswoman for the DPP told the Herald Sun that "all sentences imposed in cases prosecuted by the Director of Public Prosecutions are reviewed as a matter of course" and that no decision had been made on whether to appeal in Patterson's case.

Some Crown lawyers expressed disappointment at the length of the non‑parole period. A leading barrister quoted by local media said an appeal court might be unlikely to increase a minimum term by only a few years, noting there is little practical difference between, for example, 33 and 35 years. The prosecutor who sought life without parole described the offending as so "cruel and so horrific" that the offender was not deserving of mercy.

The DPP's review will determine whether prosecutors will seek a longer non‑parole period or argue for life without parole at the Court of Appeal. If an appeal is filed, it will proceed under Victoria's appellate procedures; if the DPP does not appeal, Patterson retains the right to appeal the conviction or sentence within the same 28‑day period.

The convictions and sentence follow a trial that examined forensic evidence and testimony about the preparation and serving of the meal in July 2023. The case has drawn significant public attention in Australia because of the unusual method of poisoning and the familial relationship between the offender and the victims. Further legal submissions and any decision to appeal are expected to be handled in the coming weeks under the statutory appeal timeframe.
