Most people who have responded to this post suggesting Rusty should be prosecuted for negligence or murder do not understand mental illness or how hard it is to get doctors to take action. Rusty tried very hard to handle the situation the best way he knew how. His mother-in-law was in the process of moving from TN to TX to be there permanently. I don't understand what people think he was supposed to do with this situation. Pack up and leave his mentally ill wife? Stay home from work and get fired from his job? Take a leave of absence and send his wife back to work? Until a person actually commits an act harmful to others or themselves you cannot force a mentally ill person to do anything against their will. Anyone who knows Rusty will tell you that he is devastated over the death of his children. He has just found out his wife was sentenced to life in prison. His reaction afterwards it not unexpected. I don't know if he can survive if they bring charges against him.
You are so correct that many people in this thread have not thought the situation through. I'll add, they have not the slightest idea what it is like to live with a person that is mentally ill.
