Follow Daily Mail Australia’s live coverage of accused mushroom chef Erin Patterson‘s murder trial at Latrobe Valley Magistrates’ Court in Morwell, Victoria.

Erin Patterson should have experienced ‘adverse outcome’ from lunch

Erin Patterson claims she ate only half of a beef Wellington laced with death cap mushrooms at her deadly lunch.

Patterson made the claim to hospital staff and a child protection officer in the days following the lunch that claimed the lives of her in-laws Don and Gail Patterson, and Gail’s sister, Heather Wilkinson.

The jury has already heard Gail Patterson ate just half of her pastie-sized beef Wellington, with her husband finishing off the rest.

Unlike Patterson, the portion was enough to make Gail violently ill within hours and eventually killed her.

On Friday, Dr Dimitri Gerostamoulos, head of forensic science at the Victorian Institute of Forensic Medicine, suggested Patterson’s portion should have caused an ‘adverse outcome’ for her.

Mushroom murder trial enters fourth week

Patterson will face her fourth week of a Supreme Court trial on Monday.

Patterson has pleaded not guilty to killing her three lunch guests and the attempted murder of Pastor Ian Wilkinson – the lone survivor of the deadly lunch.
