Erin Patterson, aged 50, is entering her fourth week of trial today at the Supreme Court, which is taking place in Morwell, located approximately two hours from Melbourne.

The trial initially started with 15 jurors, but this number was reduced to 14 last Thursday. This change occurred after Justice Christopher Beale removed a juror for possibly discussing the trial with outsiders.

The jury will be further whittled down to 12 by the end of the trial, who will be sequestered to decide whether Patterson is guilty of three murders and one attempted murder, or it was all a terrible accident.

Patterson has pleaded not guilty to all offences brought against her.

Family of Don and Gail Patterson, 70, and Heather Wilkinson, 66, who all died after consuming a death cap mushroom-laced beef Wellington at Patterson’s home in 2023 have attended every day of the trial.

The sole survivor of the lunch, Ian Wilkinson, 71, has sat in the second row of the court for most days since he gave evidence in the second week.

The jury last week heard from toxicologists who tested remains from the beef Wellington – which police seized from a bin at Patterson’s home – and found toxins from death cap mushrooms.

The factors that can make death cap mushroom consumption lethal were also revealed to be age, weight, tolerance and dosage, the jury was told.

The trial before Justice Christopher Beale will resume today.
