The first paper analyzes several multiple murder cases that have received widespread attention in the research literature, reviews that status of knowledge on multiple murder, and summarizes the book’s subsequent chapters. Additional papers argue that ideology has become a major impediment to research progress related to multiple murder, explain the reasons that mass murder has received far less research attention than has serial murder, and examine the characteristics of the sexually sadistic serial killer. Further papers analyze serial murder in historical context, question the current categories that criminologists and others use to explain serial murder, and explore the ideological dimensions of homicide. Other papers examine the emerging topic of targeting of victims and serial murderers within urban settings by a criminologist and detective, analyze the sexual component of serial homicide, and consider the special problems experienced by surviving victims of multiple murder.
