# Australian mushroom murderer Erin Patterson has lost a bid to overturn her convictions. She was sentenced in September 2025 to life behind bars with a non-parole period of 33 years, after she killed three people with a meal laced with toxic mushrooms in 2023. A panel of three judges at the Supreme Court of Victoria in Melbourne found her original sentence too lenient, calling her crimes “extraordinarily cold and calculated”. They said the case involved such shocking criminality that fixing a non-parole period was inappropriate.
