SYDNEY, Oct 28 — Australian mushroom murderer Erin Patterson will learn Friday if she has succeeded in overturning her conviction for killing three people with a poisoned beef Wellington lunch.

Patterson, 52, was found guilty last year of murdering her husband’s parents and an elderly aunt in 2023 by serving them a beef-and-pastry meal laced with lethal death cap mushrooms.

A judge sentenced her to life imprisonment, eligible for parole after 33 years.

In August this year, her lawyers argued before the Court of Appeal in Melbourne that she had suffered a miscarriage of justice.
