Erin Patterson appeals mushroom murder convictions

Australian 'mushroom killer' Erin Patterson began an appeal against her triple murder conviction, arguing that jurors were improperly housed with police and prosecution, denying her a fair trial.

The Victorian Court of Appeal heard her lawyers describe the arrangement as a 'catastrophic' failure of justice.

Prosecutors are separately appealing her sentence, seeking life in prison without parole.

The case has drawn international attention to the 2023 deaths of three people who ate death cap mushrooms at a family lunch.
