Australian woman arrested after hosting lunch that left 3 guests dead from suspected mushroom poisoning

Australian police on Thursday arrested the host of a luncheon gathering that left three guests dead from suspected mushroom poisoning and a local preacher fighting for life.

Victoria state police executed a search warrant at Erin Patterson's home at Leongatha where her former husband's parents, Gail and Don Patterson, both aged 70, Gail Patterson's sister Heather Wilkinson, 66, and her husband Ian Wilkinson, 68, gathered on July 29 for lunch.

All four guests were hospitalized the next day and only Ian Wilkinson, a local pastor, survived. He spent nearly two months gravely ill in hospital before being released on September 23.
