SYDNEY (Reuters) -An Australian woman was on Monday convicted of murdering three elderly relatives of her estranged husband with a meal laced with poisonous mushrooms, in a case that has gripped the country.
Erin Patterson, 50, was charged with the murders of her mother-in-law Gail Patterson, father-in-law Donald Patterson and Gail's sister, Heather Wilkinson, along with the attempted murder of Ian Wilkinson, Heather's husband.
The four gathered at Erin Patterson's home in Leongatha, a town of about 6,000 people some 135 km (84 miles) southeast of Melbourne, where the mother of two served them a meal of individual Beef Wellingtons accompanied by mashed potato and green beans, which were later found 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.
