An Australian woman charged with three counts of murder on accusations of killing three members of her extended family last year pleaded not guilty Tuesday.
Erin Patterson was charged in November with three counts of murder and five counts of attempted murder.
The 49-year-old mother of two is accused of killing Gail and Don Patterson, the 70-year-old parents of Erin Patterson's ex-husband, Simon Patterson, and his 66-year-old aunt Heather Wilkinson, last summer when she fed them a meal made with poisonous mushrooms.
Prosecutors allege that she intended to kill her then-estranged husband, who was not at the July 29 lunch at her home.
