Erin Patterson, the Australian woman accused of killing three relatives with a meal of death cap mushrooms baked in a Beef Wellington lunch, has been found guilty of three counts of murder and the attempted murder of the lone survivor.

Erin Patterson did not react, staring at the jury as the verdict was read out. They had found her guilty of murder and attempted murder after she laced a beef Wellington meal with death cap mushrooms that killed three people.

The jury in the trial of an Australian woman who allegedly murdered three elderly relatives of her estranged husband using poisonous mushrooms will deliver its verdict on Monday, the court said in a statement.
