Erin Patterson, an Australian woman, has been found guilty of three counts of murder and one count of attempted murder.
The charges are related to a Beef Wellington meal containing death cap mushrooms that she served.
The verdict was reached by a 12-member jury after six days of deliberation following a 10-week trial.
The incident occurred in July 2023 in Leongatha, Victoria.
The Erin Patterson murder trial generated significant media attention and public interest, leading to the creation of four dedicated podcasts.
Prosecutors accused Erin Patterson of intentionally contaminating a lunch with highly toxic death cap mushrooms, which she allegedly picked after finding their location online.
The victims who died were her former parents-in-law, Don and Gail Patterson, and Gail’s sister, Heather Wilkinson.
Heather’s husband, Ian Wilkinson, survived after a prolonged hospital stay.
Patterson’s defense argued the deaths were a “terrible accident” and that her lies to police stemmed from panic.
Prosecutors presented a case that convinced the jury “beyond reasonable doubt” of Patterson’s guilt in the triple murder.
