Many serial killers are looking for victims that fit a sexual fantasy, or who can be used as a tool for their crimes. Some, like Kemper, picked up their victims while they hitchhiked on the side of the road. Others, such as Lane, parked his semi near residential neighborhoods and walked from house to house looking for open doors. A potential assailant will usually back off if you draw too much attention to yourself, so shout at them and make noise using your fingers or anything else you can reach for. If they try to grab you, fight back and aim for the eyes, throat and crotch.
