Catherine's Killing of Price

Catherine Price tried to kill her husband by stabbing him with a butcher knife while he was sleeping. She then decapitated him, cut off parts of his body, cooks it and sets the plates at the dinner table. The police discover that after all that happened, Catherine just drives into town and withdraws a thousand dollars from Price's ATM account. How is she not in jail before this? That's the craziest thing I have ever heard. This is insane.
