Kenneth Bianchi, one of the "Hillside Stranglers", murdered women and girls of different ages, races, and appearance because his sexual urges required different types of stimulation and increasing intensity. Jeffrey Dahmer searched for his perfect fantasy lover—beautiful, submissive and eternal. As his desire increased, he experimented with drugs, alcohol, and exotic sex. His increasing need for stimulation was demonstrated by the dismemberment of victims, whose heads and genitals he preserved, and by his attempts to create a "living zombie" under his control (by pouring acid into a hole drilled into the victim's skull).
