The presumptive role of fantasy in serial sexual homicide.

The authors examined the role of fantasy as an internal drive mechanism for repetitive acts of sexual violence. A sample of 25 serial sexual murderers with three or more known victims each was compared with a sample of 17 single sexual murderers, with only one known victim each. The drive mechanism was hypothesized to be an intrusive fantasy life manifested in higher prevalences of paraphilias, documented or self-reported violent fantasies, and organized crime scenes in the serial murderers.

Serial rapists and their victims: reenactment and repetition.

The major finding in this study of 41 serial rapists is the large numbers of reported and unreported victims. For over 1200 attempted and completed rapes, there were 200 convictions. The hidden rapes or earliest nonreported victims of these men as boys and adolescents were identified from their families, their neighborhood, and their schools.
