Two scenes(1 at the beginning of the film and the other around the middle of the film) where a woman comes home and is attacked by the Candlelight Killer who grabs them by the throat and proceeds to strangle them but the scenes cut before the women actually die.
The climax is intense with the killer invading the mother and daughter's apartment knocking the mother out and actually using the mother's body as a weapon smashing Lisa's head with her mother's head and then drags Lisa into a room and starts to strangle her. The women gain the upper hand and stab the killer in the shoulder, blind him with mace, strike him several times with a baseball bat, and knock him out the window to his death. The climax is a very hard PG-13 level brutality and bloodyness and it is the only onscreen killing.
