Erzsébet Báthory (1560-1614) was a countess from the renowned Báthory family.

Katherine Knight
She had stabbed Price with a butcher's knife while he was sleeping. According to the blood evidence, he awoke and tried to turn the light on before attempting to escape while Knight chased him through the house, he managed to open the front door and get outside but either stumbled back inside or was dragged back into the hallway where he finally died after bleeding out. Later, Knight went into Aberdeen and withdrew $1,000 from Price's ATM account. Price's autopsy revealed that he had been stabbed at least 37 times, in both the front and back of his body with many of the wounds extending into vital organs. Several hours after Price had died, Knight skinned him and hung the skin from a meat hook on the architrave of a door to the lounge room. She then decapitated him and cooked parts of his body, serving up the meat with baked potato, pumpkin, zucchini, cabbage, yellow squash and gravy in two settings at the dinner table, along with notes beside each plate, each having the name of one of Price's children on it; she was preparing to serve his body parts to his children. A third meal was thrown on the back lawn for unknown reasons and it is speculated Knight had attempted to eat it but could not and this has been put forward in support of her claim that she has no memory of the crime. Price's head was found in a pot with vegetables.
