The incident occurred in Leongatha, Australia. Erin hosted a dinner, inviting her in-laws and her husband’s aunt and her husband. The meal included beef, and all guests consumed the food. Within a week, three of the guests became seriously ill and died. Investigations revealed that the food contained amatoxin poison from poisonous mushrooms. Erin was identified as the perpetrator, having deliberately poisoned the food. She was in a dispute with her husband, Simon, involving separation and child support. The court heard evidence that Erin had also attempted to poison her husband previously. Erin was found guilty, and her sentencing is yet to be decided.
Erin had lied to her guests, claiming she had been diagnosed with cancer and needed their advice. In reality, she had no cancer. She was accused of using this lie to lure them to the dinner and carry out her deadly plan. When she realized she was caught, she claimed that the deaths were due to food poisoning. However, this was proven false.
