Erin Patterson's conviction for the deaths by poisoning of her estranged husband's relatives has prompted fevered speculation across Australia about her motive.

The 50-year-old's in-laws died in 2023 after eating beef Wellingtons prepared by Patterson - they were later found to contain toxic mushrooms.

The Supreme Court has revealed the jury was accidentally sequestered in the same hotel as a key police witness and two members of the prosecution's team for the majority of the deliberations.
