Slaughtered Socialites (1996)

Set in the early 1960's, Artie, the deranged janitor from Slaughtered Secretaries, returns to wreak havoc on a doctor and her patients. Dr. Sorens (Dawn Murphy) has taken Artie under her wing and given him a job, not believing that he killed the three secretaries five years earlier. But she's wrong and they all pay the price for her ignorance!
