A jury last month found Erin Patterson lured her mother-in-law Gail Patterson, father-in-law Don Patterson and Gail's sister, Heather Wilkinson, to lunch at her home and poisoned them.

One alleged attempt left Simon Patterson in a coma, with his family twice told to say their goodbyes.

Erin Patterson’s husband said he felt ill after eating a penne bolognese, chicken curry and sandwich wrap she cooked for him.
