Communion (1976)

(a.k.a. Alice Sweet Alice)

Alice is a withdrawn 12-year-old who lives with her mother and her younger sister, Karen, who gets most of the attention from her mother, leaving Alice out of the spotlight. When Karen is found brutally murdered in a church, suspicions start to turn toward Alice. But could a 12-year-old girl really be capable of such savagery?
