41. Katherine wasn’t done yet. After skinning Price, she decapitated the corpse of Price and cooked his body parts.

42. The meat was then served at dinner table in two settings along with gravy, yellow squash, cabbage, courgette, pumpkin and baked potato.

43. Who was she serving the food to? She was actually preparing to serve the meat to Price’s children. Each plate had a note by its side and the notes had the name of Price’s children on them.

44. Yet another meal was found in the back lawn. Why exactly was it thrown away is not known but it is believed that Katherine tried eating it but failed and threw it away.

45. Price’s head was also found in a pot alongside some vegetables. The pot, when discovered, was pretty warm at around 40ºC to 50ºC. This suggested that Katherine cooked Price’s head somewhere in early morning so that it could be served to the children when they come back.
