There was a movie about serial killer which i rarely remember anything about it only last scene which they main characters of the movie lock the guy in place under the ground. And the place was full with blondy wigs and lady clothes as the killer is acting like his death sister or something similar ……

Answered question

When did you see it? When was it made? Not a perfect match, but maybe “Psycho” (1960) or one of its sequels?:
