Erin Patterson, 52, was sentenced to life in prison with a non-parole period of 33 years after being found guilty of murdering three relatives and attempting to kill a fourth with death cap mushrooms in 2023, according to 1News and Variety.
Patterson appealed her conviction, claiming a substantial miscarriage of justice during her trial, while the Director of Public Prosecutions (DPP) appealed the sentence, arguing it was too lenient, as reported by 7NEWS and AFP.
Patterson appeared via video link from prison during the appeal hearing, which was heard in August, as noted by 1News and 7NEWS.
The Victorian Court of Appeal dismissed Patterson’s appeal of her convictions and upheld the prosecution’s challenge to the leniency of her 33-year non-parole sentence, as confirmed by 1News and 7NEWS.
Justice Stephen McLeish described Patterson’s offending as “extraordinarily cold and calculated,” according to 7NEWS and AFP.
Patterson’s defense lawyer, Richard Edney, argued the matter was “very serious” and fundamentally undermined the trial, as reported by 7NEWS.
The DPP argued that Patterson’s time in prison differs from the judge’s conclusion that she would have to be in solitary confinement for several years, as noted by 7NEWS.
The Court of Appeal increased Patterson's sentence for poisoning her relatives and dismissed all grounds of her appeal, as confirmed by ABC News and 1News.
The court ruled that the nature of Patterson's offenses makes the fixing of a non-parole period inappropriate, as stated by Justice Peter Kidd in 1News.
Patterson’s appeal was dismissed, and she will likely die in prison, as reported by SBS and The Guardian.
A six-part drama about the Leongatha mushroom murders, with New Zealand actress Melanie Lynskey set to play Erin Patterson, has been announced for Paramount+, as reported by 1News and Smh.
