I have no idea how the strange, excessive, constantly changing drug ‘cocktail’ she was on - without proper monitoring!- would affect anyone, especially if they were already suffering mental illness. That was a big issue in the case, and would be an enormous problem for me if I had been on that jury.
Everyone who was close to her testified to her love for her children and the quality of her mothering. As far as I’m aware, nobody had anything bad to say about her. What changed and made her murderous?
Are you at all troubled that she put research into how to kill her children?
