When I interviewed Kemper, it became clear that all of his adult crimes were in reaction to his punitive and emotionally abusive mother, who belittled him by telling him he wasn’t good enough for the beautiful coeds at the University of California, Santa Cruz, where she worked. And once he worked up the nerve to kill her and, by association, her friend, instead of targeting the surrogate women whom she said he could never have, he was done. There was no point to his killing any longer. Turning himself in seemed the logical and prudent thing to do.
