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.

Patterson, 50, was charged with murdering three relatives of her estranged husband by serving a beef Wellington laced with toxic mushrooms over lunch in 2023.

A doctor who treated some of the victims of the 'mushroom murderer' explains the moment he realised Erin Patterson committed the deadly crime.
