The Motivation Behind Serial Sexual Homicide: Is It Sex,Power, and Control,or Anger?*

Controversy exists in the literature and society regarding what motivates serial sexual killers to commit their crimes. Hypotheses range from the seeking of sexual gratification to the achievement of power and control to the expression of anger. The authors provide theoretical, empirical, evolutionary, and physiological support for the argument that serial sexual murderers above all commit their crimes in pursuit of sadistic pleasure. The seeking of power and control over victims is believed to serve the two secondary purposes of heightening sexual arousal and ensuring victim presence for the crime. Anger is not considered a key component of these offenders' motivation due to its inhibitory physiological effect on sexual functioning. On the contrary, criminal investigations into serial sexual killings consistently reveal erotically charged crimes, with sexual motivation expressed either overtly or symbolically. Although anger may be correlated with serial sexual homicide offenders, as it is with criminal offenders in general, it is not causative. The authors further believe serial sexual murderers should be considered sex offenders. A significant proportion of them appear to have paraphilic disorders within the spectrum of sexual sadism. "sexual sadism, homicidal type" is proposed as a diagnostic subtype of sexual sadism applicable to many of these offenders, and a suggested modification of DSM criteria is presented.     

Occupational licensing and the quality of service

This paper gathers, presents, and evaluates current state of economic research concerning the interconnection between occupational licensing (and other occupational) restrictions and quality of service. It considers empirical evidence on the effect of licensing on quality of service delivered; uses a simple model to examine the distinction between this type of quality and the more crucial aspect, quality received; and summarizes the empirical evidence on quality received.     

A father marries his daughters: a case of incestuous polygamy

Polygamy is a risk factor for incest. This case report of incest and polygamy portrays the dynamics that dominated this family's identity. The father indoctrinated and groomed his biological daughter and stepdaughter for sexual gratification in a cult-like atmosphere, and secretly married both of them. He justified his acts to the family members under the guise of religion, but he later denied allegations of polygamy and sexual contact with his daughters when confronted by the authorities. Ultimately, his parental rights were terminated in family court. The authors interviewed the primary victim and reviewed extensive evidence, including videotapes of the victims talking with detectives and also privately amongst each other. Videotape dialogue excerpts capture how these young girls individually coped with the sexual abuse and responded to becoming child wives in a polygamous family. Criminal charges ultimately were not pursued because the key witness refused to testify against her biological father.
