Erin Patterson Appeals 3-Murder Conviction Over Jury Hotel Mix-Up During Deliberations

Q: What hidden digital clues about the deadly lunch are Erin Patterson's lawyers desperately trying to exclude from the court record?

Erin Patterson’s lawyers are trying to keep out digital evidence that prosecutors used to suggest she may have deliberately sourced death cap mushrooms before the fatal lunch. The key material is mobile phone tower data that prosecutors said placed Patterson’s phone near Loch and Outtrim, two areas where death cap sightings had been posted online. Linked to that was evidence from iNaturalist, the citizen-science website where those mushroom sightings were reported. Her appeal argues the combination was too speculative because the tower data only showed her phone may have been in those broader areas, not at the exact mushroom sites, and there was no proof she had actually seen the iNaturalist posts. Her lawyers are also fighting over photographs and videos of mushrooms found on an SD card at her home. Unlike the phone and iNaturalist material, the defence wanted those images admitted at trial because they said the files supported Patterson’s claim that she had a longstanding innocent interest in mushroom foraging. On appeal, they argue the judge wrongly excluded them, which they say forced her into the witness box and undermined her right to silence. A further digital strand concerns Facebook-related evidence. The appeal challenges the use of Facebook messages and material involving Patterson’s Facebook friends, arguing it caused unfair prejudice and was later used by prosecutors to imply motive, despite opening the case by saying they would not rely on motive.

Patterson's lawyers told Victoria's Court of Appeal the jury's guilty verdicts should be quashed and a retrial ordered because 12 sequestered jurors shared a hotel with prosecution staff, a lead detective and journalists.
An email sent on 7 July revealed the overlap during deliberations; prosecutors acknowledged they had known for days, but said jurors were kept on a separate floor, ate separately and had no interaction with outsiders.
Defence counsel Richard Edney called the episode a "fundamental irregularity" in the trial's "most critical week," arguing even incidental sightings could create subconscious influence despite no evidence of direct contact.
Prosecutor Brendan Kissane said "the system worked" because jury keepers supervised the panel throughout and every account showed no contact, distinguishing the case from retrials triggered by actual jury interference.
Patterson, convicted over a 2023 mushroom-poisoning lunch that killed 3 and seriously injured 1, has 7 appeal grounds in total; judges are also weighing a prosecution bid to remove her parole period.

Overview

In July 2023, Erin Patterson served a fatal beef Wellington lunch laced with death cap mushrooms to her in-laws and their relatives, resulting in three deaths and one survivor. Patterson herself was unharmed, which prosecutors argued pointed to deliberate poisoning. She was convicted and sentenced to life in prison, but her appeal in 2026 focused on a jury hotel mix-up and other alleged trial errors. The prosecution cross-appealed, seeking life without parole. The case became a media sensation, with intense public scrutiny shaped by gendered stereotypes and emotional judgments, raising questions about fairness and the impact of public opinion on justice.
