I think I saw her. I saw an episode of Dr Drew whose guests were people who had family members murdered or were murderers. One of the guests was Andrea Yates ex husband. I was shocked.
Andrea Yates is mentally ill. However, her husband would not help her recover. It was for religious reasons mainly. He was head of his household according to his church and pastor. Her doctors advised her not to have any more children; but he and his pastor overruled that and her medicine was not monitored. I think her insurance ran out too. He was anything but helpful.
Yes Andrea Yates is mentally ill and should remain locked up. If she is ever to be sane again she will realize what she did and probably kill herself. Her husband however is unrepentant. He is equally responsible for the deaths of those children and he should go to jail for life.
