Erin Patterson was sentenced to life in prison on Monday after a Melbourne Supreme Court jury found her guilty of three counts of murder and one count of attempted murder for a 2023 lunch that used deadly death-cap mushrooms, a case that captured nationwide attention.

Justice Christopher Beale described the crimes as a "profound and devastating betrayal of the trust and love extended to her" and said Patterson had inflicted "untold suffering" on the victims' families. He said the offending was planned and aggravated by an elaborate cover-up and Patterson's refusal to assist investigators. Patterson will be eligible for parole in 2056, when she is 82.

The lunch in the regional Victorian town of Morwell in 2023 left three people dead and one man, Ian Wilkinson, critically ill but alive. Wilkinson, 71, the sole surviving guest from the meal, spoke publicly outside the court steps for the first time since the trial, thanking police, medics and legal teams for their work and urging the public to show kindness. "Our lives and the life of our community depends on the kindness of others," he said.

Wilkinson had previously delivered an emotional victim impact statement in court describing the daily silence in the house he shared with his wife of 44 years, Heather, who died after the meal. He told the court the grief had left him feeling "half alive without her." The other deaths were Don and Gail Patterson, the parents of Erin Patterson's estranged husband.

The prosecution said Patterson deliberately prepared and served food tainted with death-cap mushrooms, causing the rapid and brutal decline of three guests and severe poisoning of Wilkinson. Prosecutors argued the offending was premeditated and executed with the intent to kill. The judge said Patterson showed no pity for her victims and noted her continued assertions of innocence.

People outside the court as sentencing concluded

The case drew extraordinary public and media interest across Australia and internationally. Spectators queued daily for seats inside the courtroom, thousands discussed details online, multiple podcasts followed the proceedings, and streaming services and broadcasters documented the trial. Several books and a television drama in development were reported to be in the works. Family members repeatedly told the court that intense media coverage compounded their grief and caused ongoing distress.

Family victim impact statements read in court described pervasive intrusion and fear. The estranged husband, Simon Patterson, who lost his parents in the poisoning, did not attend the unanimous guilty verdict or Monday's sentencing and had his written statement read by a relative. He told the court the family had faced people waiting at their front door, intrusive camera crews and strangers showing "a threatening interest" in their private lives.

Justice Beale said Patterson had traumatised four generations of the Patterson and Wilkinson families and had robbed Patterson's children of their grandparents. He stopped short of the maximum sentence in part because of the "extreme isolation" the judge said Patterson would face as a notorious prisoner.

Prosecutors also presented evidence that Patterson allegedly prepared an additional contaminated dish intended for her estranged husband, a beef Wellington that was never served. That detail, they said, showed a wider pattern of conduct and strengthened the case for planning and deliberate intent.

Wilkinson, who survived after emergency medical treatment, praised the clinicians who saved his life and offered thanks to those who "brought to light the truth of what happened to three good people." Outside court he appealed for the public and media to respect his family's privacy as they continued to grieve and recover.

Patterson was escorted from the courtroom shortly after 10:00 local time and led to begin a life sentence in custody. She has until midnight on Oct. 6 to lodge an appeal against her conviction or sentence.

The case has prompted discussion in Australia about the responsibilities of media covering traumatic criminal proceedings and the impacts of intense coverage on victims' families and local communities. Families who lost loved ones in the poisoning said the public attention had turned their trauma into entertainment and left them constantly vigilant about their privacy.

Court officials, police and forensic teams testified across a lengthy trial that focused on toxicology, the sourcing and preparation of the meal, and Patterson's actions before and after the lunch. Defence counsel maintained Patterson's innocence at trial, but the jury returned unanimous guilty verdicts on the charges.

The legal outcome marks the end of criminal proceedings for the families involved, though civil and other legal matters, including any appeal, could continue. For Ian Wilkinson and the other relatives, the sentencing offered a measure of finality while they seek to rebuild their lives after a poisoning that one judge characterised as among the worst forms of criminality because of its betrayal of trust and premeditation.
