Australian Court Orders Mushroom Murderer to Spend Life in Prison

An Australian appeals court ordered Erin Patterson to spend the rest of her life in prison on Friday after rejecting her conviction appeal and removing a 33-year non-parole period.

The Victorian Court of Appeal handed down the unanimous decision in Melbourne, upholding the murder convictions for a 2023 poisoned lunch that killed three relatives and sickened a fourth.

The ruling ensures that the 51-year-old will not be released from prison at age 82, resolving a prosecution challenge that argued her original sentence was manifestly inadequate.

Justice Peter Kidd told the court that the nature of the appellant's offenses made fixing a non-parole period inappropriate.

Lawyers for Patterson had argued seven grounds of appeal, including a hotel booking mishap that placed jurors near prosecutors and police witnesses during deliberations.

Richard Edney, a lawyer representing Patterson, told the court in August that the failure to properly separate the jury during deliberations represented a fundamental irregularity.

The defense also claimed the trial judge erred by blocking evidence regarding her foraging hobby while allowing other disputed materials, according to the BBC and The Guardian.

However, three appeal justices dismissed all seven grounds, ruling that the trial was fair and the convictions stood.

Justice Stephen McLeish said on behalf of the panel that Patterson maintained an intent to murder all four victims for nearly three weeks.

"This offending was extraordinarily cold and calculated and stands to be denounced in the strongest terms," said Justice McLeish.

The panel noted that Patterson engaged in an elaborate series of deceptions after serving a beef Wellington dish laced with death cap mushrooms.

Those deceptions included false cancer claims to explain the absence of her children and repeated false assertions about the source of the mushrooms.

Patterson did not attend the Melbourne courtroom in person, watching the proceedings via a video link from the high-security Gordon Unit.

Patterson now has until November 27 to decide whether to launch a final appeal to the High Court of Australia.
