car. He then began picking up young women and peacefully letting them go. According to Kemper, he picked up around 150 such hitchhikers before he felt homicidal sexual urges, which he called his "little zapples," and began acting on them. Later murders Between May 1972 and April 1973, Kemper killed eight people — all women. He would pick up female students who were hitchhiking and take them to isolated areas where he would shoot, stab, smother, or strangle them. He would then take their bodies back to his home, where he decapitated them, performed irrumatio on their severed heads, had sexual intercourse with their corpses, and then dismembered them. During this 11-month murder spree, Kemper killed five college students, one high school student, his mother, and his mother's best friend. Kemper has stated in interviews that he often searched for victims after having arguments with his mother and that she refused to introduce him to women attending the university where she worked. He recalled: "She would say, 'You're just like your father. You don't deserve to get to know them'." Psychiatrists, and Kemper himself, have espoused the belief that the young women were surrogates for his ultimate target: his mother. Mary Ann Pesce and Anita Luchessa On May 7, 1972, Kemper was driving in Berkeley, when he picked up two 18-year-old hitchhiking students from Fresno State University, Mary Ann Pesce and Anita Mary Luchessa, with the pretense of taking them to Stanford University. After driving for an hour, he managed to reach a secluded wooded area near Alameda, with which he was familiar from his work at the Highway Department, without alerting his passengers that he had changed directions from where they wanted to go. It was there that he handcuffed Pesce and locked Luchessa in the trunk, then stabbed and strangled Pesce to death, subsequently killing Luchessa in a similar manner. Kemper later confessed that while handcuffing Pesce, he "brushed the back of [his] hand against one of her breasts and it embarrassed [him]", adding that he said, "'Whoops, I'm sorry' or something like that" after grazing her breast, despite murdering her minutes later. Kemper put both of the women's bodies in the trunk of his Ford Galaxie and returned to his apartment. He was stopped on the way by a police officer for having a broken taillight, but the officer did not detect the corpses in the car.
