'Mushroom murderer' Erin Patterson is fighting to overturn her convictions and is claiming that there has been a miscarriage of justice. Last year, she was found guilty of murdering three of her estranged husband’s relatives by purposely poisoning them with a beef Wellington laced with toxic death cap mushrooms. She was also found guilty of attempted murder of a fourth person. #Mushrooms #ErinPatterson #Appeal #Australia #C4news
