Erin Patterson files appeal against murder convictions
Erin Patterson, the 51-year-old Australian woman sentenced to life in prison for poisoning three relatives with toxic mushrooms, has formally lodged an appeal against her convictions, court records show.
The move follows a judge's approval for Patterson's legal team to challenge the verdicts, though the specific grounds for the appeal remain undisclosed. Under Australian law, appeals are not automatic; defendants must demonstrate potential legal errors in their trial.
Background: A deadly meal and a disputed verdict
In 2023, Patterson was convicted of murdering her in-laws Don and Gail Patterson, both 70, and Gail's sister Heather Wilkinson, 66, after serving them a beef Wellington meal laced with death cap mushrooms at her Victoria home. Heather's husband, Ian Wilkinson-a local pastor-survived the poisoning but continues to suffer long-term health complications after emerging from a coma.
Throughout the 11-week trial, Patterson insisted the poisonings were accidental, claiming she had unknowingly included toxic mushrooms in the dish. Prosecutors, however, argued she had deliberately foraged the deadly fungi, deceived her victims by falsely claiming she had cancer, and later obstructed justice by lying to police and destroying evidence.
A jury of 12 unanimously found her guilty on all charges after seven days of deliberation. She was sentenced to life imprisonment with a non-parole period of 33 years-the longest term ever imposed on a female offender in Australia for such crimes.
Procedural delays and prosecutors' counter-appeal
The appeal was filed on Monday, weeks after the original 28-day deadline expired on 6 October. A recent procedural rule allowed Patterson's lawyers an extension without requiring justification. Meanwhile, prosecutors have also filed an appeal, arguing her sentence was "manifestly inadequate."
The case drew intense public scrutiny, with media crowds packing the small courtroom in Morwell during the trial. Patterson's estranged husband, Simon Patterson, testified that he had avoided the fatal meal after suspecting for years that his wife had been trying to poison him. Medical records later revealed he had twice nearly died from severe illnesses linked to her cooking, including a coma and emergency bowel surgery.
Life behind bars: Isolation and notoriety
Patterson is currently held in the Dame Phyllis Frost Centre, a maximum-security women's prison in Melbourne. During sentencing, Justice Christopher Beale noted she spends 22 hours a day in solitary confinement due to her "major offender status," with no contact with other inmates.
"She will remain a notorious prisoner for many years to come, and, as such, remain at significant risk from other prisoners," the judge stated.

What's next
The Court of Appeal will now review Patterson's case, though no timeline for hearings has been set. If successful, the appeal could overturn her convictions or reduce her sentence. Prosecutors' parallel challenge to the sentencing length adds further complexity to the legal battle.
