An Australian woman was convicted on Monday for the murder of three elderly relatives of her estranged husband through a meal laced with toxic mushrooms, in a case that has captivated the nation.

Erin Patterson, aged 50, faced charges for the murders of her mother-in-law, Gail Patterson, father-in-law, Donald Patterson, and Gail’s sister, Heather Wilkinson. She was also charged with the attempted murder of Ian Wilkinson, Heather’s husband.

The incident occurred when the four relatives gathered at Erin Patterson’s residence in Leongatha, a town with a population of about 6,000, located approximately 84 miles southeast of Melbourne. There, the mother of two served them a meal of individual Beef Wellingtons, complemented by mashed potato and green beans, which were later discovered to contain death cap mushrooms.

On Monday, the jury in the case found her guilty of all four charges, the court heard in Morwell, a town around two hours east of Melbourne where the trial was being held.

Patterson, who had pleaded not guilty to all charges, saying the deaths were accidental, will be sentenced at a later date.

The 10-week trial attracted huge global interest, with local and international media descending on Court 4 at the Latrobe Valley Magistrates’ Court in Morwell, the nearest court to Patterson’s home where she had requested to be tried, despite being warned of lengthy delays.

State broadcaster ABC’s daily podcast on proceedings was consistently among the most popular in Australia during the trial, while several documentaries on the case are already in production.
