Victorian Police have opened an investigation after a 53yo Melbourne woman died and 2 others fell sick at a holistic health retreat in Clunes, about 30km north of Ballarat. Nothing’s confirmed, but reports say investigators are looking into whether the trio had a “mushroom-based” drink at the Soul Barn retreat. A police spokesperson says officers and paramedics were called when the woman went into cardiac arrest “after ingesting a drink about 12pm” on Saturday. “Investigations remain ongoing and police will prepare a report for the coroner,” the spokesperson said. The victim hasn’t been named, but police say she’s from the Melbourne suburb of Ringwood North. As for the 2 others, they were taken to Ballarat Base Hospital for observation. If it’s ringing bells about another mushroom death case, alleged murderer Erin Patterson is due in court next Monday.
