Twelve jurors will have to consider the prosecution's case, the defence arguments and a judge's directions before they reach their verdicts in Erin Patterson's murder trial.

Overview

  • Jurors retired to begin deliberations on charges of three murders and one attempted murder after a nine-week trial
  • Justice Christopher Beale concluded his four-day charge by outlining how jurors should weigh Patterson’s admitted falsehoods and maintain a media blackout
  • The 14-member panel was reduced by random ballot to a sequestered 12-juror group tasked with delivering unanimous verdicts on each count
  • Patterson faces three counts of murder and one count of attempted murder for allegedly dosing her in-laws’ beef Wellington with deadly death cap mushrooms
  • Toxicology experts and security footage of a discarded dehydrator revealed trace amatoxins supporting the prosecution’s claim of intentional poisoning
