Rape or mutilation most often takes place after the victim of a serial killer has been rendered unconscious, is dying, or is dead. The disorganised serial killer is uncomfortable with any kind of interaction with the victim and prefers a passive and doll-like subject. As Edmund Kemper said of his victims, he needed to “possess them in the way I wanted to; I had to evict them from their human bodies.” Sexual acts committed on the victim often involve the insertion of foreign objects into the body’s orifices (insertional necrophilia). Parts of the body, especially the buttocks and breasts, are sometimes bitten or slashed and stabbed, as are often the thighs, abdomen, and neck. Very often the killer does not complete the sexual act and semen is found on the victim’s clothing or nearby. Sometimes the killer has sex with the victim’s wounds. Parts of the victim’s body might be cut away and missing.
