I Dismember Mama (1972)

Synopsis
Originally released as Albert and Annie, this low-budget, poorly lighted, non-action, slasher film features Albert (Zooey Hall) as a deranged youth locked up in a mental institution by his super-rich mother until one day he is stopped from watching soft-porn movies in his room, and, upset at this deprivation, he escapes and starts killing women. Albert first returns to his family mansion where he torments and kills the buxom housekeeper. When her nine-year-old daughter Annie (Geri Reischi) comes in from school, Albert sees her as a perfect, innocent female and is compelled to protect her at all costs -- even if it means killing off her impure, older sisters. If his sexual urges take over at night, Albert goes out and kills other "immoral" women -- until the police, through a maddeningly unrealistic bureaucratic maze, track him to a warehouse of mannequins -- and the chase is on, at least for awhile. ~ Eleanor Mannikka, All Movie Guide
