Mushroom murderer trial undermined by 'catastrophic' hotel mix-up, court told

Lawyers for Erin Patterson, convicted of murdering three relatives with poisonous mushrooms, are seeking to overturn her conviction due to a procedural error involving jurors staying at the same hotel as prosecution witnesses. The prosecution is simultaneously appealing her sentence, arguing that the 33-year parole period is insufficient.

Lawyers for Australian mushroom murderer Erin Patterson say her conviction was undermined by a "catastrophic" mix-up that led to the jury staying at the same hotel as prosecutors and a key witness.
Patterson is serving a life sentence after killing three of her relatives and trying to kill another by serving them a beef Wellington containing death cap mushrooms at her Victoria home in 2023.
Her lawyers also argued some evidence in the trial was too speculative, while evidence crucial to their own case was wrongfully excluded.
At the same hearing, Victoria's Director of Public Prosecutions is appealing against the sentence, arguing a 33-year parole period is "manifestly inadequate".
Patterson's victims include her in-laws Don and Gail Patterson, both 70, and Gail's sister Heather Wilkinson, 66.
