Young boy pushes grandma down stairs but he tries killing baby sister too. Dad knows
This is a movie I am describing. There is a family consisting of a mother, father, infant and a possessed little boy. The boy is about 6 to 10 years of age. He is jealous or something but in any case he kills the grandmother and sends his mom to the mental hospital. His dad becomes aware and no one will believe him and they keep trying to blame him as the reason for the mysterious events happening. This movie is less than ten years old. Please help this is driving me crazy.
