She didn't do it! She was almost a victim herself! Lucy came from the seance and exacted revenge for herself and her mom thru that dummy. A 10 year old couldn't kill 5 victims - 2 adults - 3 older girls - with that sledge hammer. They summoned her, ridiculing her still tho she was dead, and got what the little shits and your parents deserved. Glad you got away.
