Erin Patterson, Australia’s ‘Mushroom Murderer,’ Appeals Verdict

Erin Patterson, the Australian convicted of the so-called Mushroom Murders, will be appealing her convictions and sentence in a Melbourne court, according to the latest update from the July 2025 trial. Patterson was found guilty of poisoning four family members with death cap mushrooms, resulting in the deaths of three individuals - her parents-in-law Don and Gail Patterson, and Gail's sister Heather Wilkinson.

She was also accused of attempting to murder Wilkinson's husband, Ian. Patterson is now appealing her verdict, claiming that there were miscarriages of justice in the original trial, as well as alleging a fundamental irregularity during jury sequestering that requires her convictions to be quashed and a retrial to be held. Her lawyers describe this irregularity and argue that the 33-year non-parole period for her sentence is "manifestly inadequate."

Despite not being expected to attend the hearings, Patterson maintains her innocence, claiming the poisoning was a tragic accident. The prosecution, however, disputes this and asserts that the alternate plates were used to ensure Patterson could identify which portions were poisonous.
