You and Nicole run as fast as you can, leaving Richard behind. You go up to the first house that has its porch lights on and bang on the door.
An elderly woman answers and lets you inside. You call the police, and they show up a couple minutes later. You take them back to the house where you saw the Halloween killer. The police rescue the family tied up in the living room, but the killer is gone. And you never see Richard again.
THE END
