Little is known about Sexual Murderers -- those who kill in a sexual context. Recent studies have compared their backgrounds and characteristics with that of rapists and/or violent (non-sexual) offenders. This translation of a French original by the renowned Jean Proulx challenges existing knowledge on sexual murders, offers new tools for profiling and interrogation, and helps to establish a new research base. Current theories of sexual murder, its prevalence, reasons including attachment theories, profiling and interrogation techniques are all addressed in Proulx's distinctive, thought-provoking style.
