The trial of Erin Patterson for allegedly murdering her in-laws by serving them a lunch laced with death cap mushrooms has started in a Victorian court.

Patterson, 50, faces three charges of murder and one charge of attempted murder relating to a beef wellington lunch she served at her house in South Gippsland in 2023.

The 15-member jury in the supreme court trial was empaneled on Tuesday.

Patterson has pleaded not guilty to murdering or attempting to murder the relatives of her estranged husband, Simon Patterson.

She is accused of murdering Simon’s parents, Don and Gail Patterson, his aunt Heather Wilkinson, and attempting to murder Ian Wilkinson, Simon’s uncle and Heather’s husband.

Opening submissions in the case are expected to be made on Wednesday by Nanette Rogers SC, the prosecutor, and Patterson’s lawyer Colin Mandy SC.

The trial before Justice Christopher Beale in Morwell continues.
