This is the Buckley Family. The children’s names were Susan &John. As a Halloween joke, the kids in the neighborhood were going to get a dummy & pretend to chop its head off. The Buckley children thought it would be hilarious to actually kill their mum, so when the kids walked up the door they got an axe and slaughtered her. Once everyone figured out what they had done, they called the police, but the kids were long gone by then. The only picture of them was this photo, taken by a trick or treater. The mothers body was found half eaten.
