Australian woman guilty of triple murder involving poisonous mushrooms
Australia is known for its surfers, cute koalas and barbecues with thick steaks. But recently, all attention turned to a very unpleasant lunch in Leongatha (Victoria). That’s where fifty-year-old Erin Patterson served her in-laws a classic beef Wellington—but with a surprise nobody would wish on anyone: poisonous mushrooms. The result? Three deaths and a trial that even Netflix would be jealous of.
Poisonous mushrooms in the leading role
According to the court, it was not a stupid mistake: this week, Erin Patterson was found guilty of three murders and one attempted murder. The murder weapon? Not a knife or gun, but a serving of death cap mushrooms, also known as every mycologist’s nightmare.
The victims were her former parents-in-law Don and Gail Patterson, plus Gail’s sister Heather. Only Ian Wilkinson, Heather’s husband, survived the ill-fated dinner.
Sick after twelve hours
The lunch began with a pretext. Patterson had invited her in-laws under the guise of an important family meeting about medical news. She supposedly had ovarian cancer. Spoiler alert: that turned out to be a lie too.
Twelve hours after the meal, the guests began to become seriously ill. At the hospital, it quickly became clear that they had suffered mushroom poisoning. Don, Gail and Heather died several days later.
But she wasn’t sick?
What makes it even more suspicious: Erin herself had no symptoms at all. She even insisted on going home after a medical check-up. While her guests lay seriously ill in intensive care, she maintained that everything was an unfortunate coincidence.
And then it gets even darker: she gave leftovers from the meal to her children. But, she claimed, she had “removed the mushrooms”.
A plate with a different colour
Victim Heather had previously told someone that Erin had a different-coloured plate from everyone else. Coincidence? Maybe. But in a case where everything is suspicious, nothing goes unnoticed.
During the trial, even more lies came to light. Patterson initially said that she had bought the mushrooms at an Asian supermarket. Later, she admitted that she had picked them herself, in a place known for growing poisonous specimens.
No remorse, just silence
The woman herself remained strikingly quiet during the verdict. She listened to the judgment in silence and did not shed a tear. It is not yet known whether she will appeal. But with a possible life sentence looming, that is to be expected.
Just this: how poisonous are those mushrooms, really?
Death caps (Amanita phalloides) are responsible for 90% of all fatal mushroom poisonings worldwide. Just one cap can be fatal to an adult. Symptoms only begin after 6–12 hours, by which point your liver is already in serious trouble. Want to be on the safe side? Simply don’t pick them.
