Erin Patterson Appeals Mushroom Murder Convictions
The Australian woman convicted of killing three relatives with death cap mushrooms argues jury sequestration and unfair cross-examination tainted her trial.
Erin Patterson, the Australian woman convicted of murdering three of her estranged husband's relatives with poisoned beef Wellington, began a two-day appeal Wednesday before the Victoria state Court of Appeal.
Patterson, 51, was found guilty last July of three counts of murder and one of attempted murder over a July 2023 lunch at her home in Leongatha that killed Don and Gail Patterson and Gail's sister, Heather Wilkinson. Heather's husband, Ian Wilkinson, survived after weeks in the hospital. She was sentenced in September to life in prison, with a minimum of 33 years before she can seek parole.
Prosecutors are separately appealing the sentence as too lenient, arguing Thursday that Patterson should receive life without parole.
Defense attorney Richard Edney told the three-judge panel that jurors had been sequestered in the same hotel as a police witness and members of the prosecution team, calling it a "catastrophic" breach. Prosecutor Brendan Kissane said there was no evidence of actual contact between jurors and outside parties.
Defense lawyer Veronika Drago argued that phone tower evidence placing Patterson near towns where death caps had reportedly been sighted was unfairly prejudicial, showing only that her phone "may have been in the area." Prosecutor Jeremy McWilliams countered that the evidence showed she had an opportunity to deliberately source the mushrooms.
The defense also argued that prosecutor Nanette Rogers' five-day cross-examination of Patterson was "unfair and oppressive," and that the trial judge wrongly allowed evidence from Patterson's Facebook contacts. Drago further contended a miscarriage of justice occurred because prosecutors initially said there was no evidence of motive, then later suggested animosity toward her husband's family as one.
Patterson watched Wednesday's hearing by video link from prison. She has maintained the poisoning was accidental. If her appeal succeeds, judges could overturn her convictions and order a retrial.
