One Dark Night (1983) on Netflix

Six girls have been found murdered in the apartment of famed Russian occultist, Karl "Raymar" Raymarseivich, and police cannot explain the bizarreness of it. All six girls were stuffed into a closet, there were plates and silverware embedded in the walls, and when Raymar's body was lifted onto a stretcher, bolts of electricity shot out from his fingers. Not even his estranged daughter, Olivia McKenna (Melissa Newman), or her down-to-earth husband Allan (Adam West) knows what went on; that is, until they meet Samuel Dockstader (Donald Hotton), a feature writer for "The World of the Occult". Dockstader, once a friend to Raymar, explains that Raymar was a psychic vampire who gained great powers of telekinesis by kidnapping young girls, terrorizing them, and feeding off the bioenergy they produced. Allan doesn't belive a word of it, but Dockstader shows Olivia a set of Kirlian photographs to demonstrate how bioenergy works and gives her an audiotape that outlines his findings from "the Raymar telekinesis experiment." Olivia believes him.
