Silent Scream (1980)

Terror so sudden there is no time to scream.

Four college students, unable to find on-campus housing, take up residence in Mrs Engels's hilltop mansion, where she lives with her strange son, Mason, and her daughter, Victoria, whom Mrs Engels secretly keeps hidden in the attic, a botched lobotomy having left her mute and homicidal. After one of the students is found dead, a police investigation is launched, which uncovers the history of the mansion and its owners, as the remaining students become endangered.
