The sex killer

The Neuropsychology and Neurology of Sexual Deviance: A Review and Pilot Study

“…Overall, these precursory reports tended to emphasize the link between sexual deviance and temporal lobe anomalies, although the conclusions are tentative and replications with recent imaging techniques and improved approaches for volumetric measurement are warranted. First, a dilatation of the temporal horn of the lateral ventricle, especially in the right hemisphere, has been found in sadistic offenders compared with nonsadistic sexual and nonsexual offenders (Langevin et al 1985;Hucker et al 1988;Langevin et al 1988a). Intriguingly however, these sadistic sexual offenders were significantly better in neuropsychological testing than the nonsadistic sexual offenders (Hucker et al 1988), rendering the interpretation difficult.…”

Offense Pathways of Non-Serial Sexual Killers

“…These studies have concerned the comparison of sexual killers to non-homicide sexual aggressors (perpetrators of rape or attempted rape). For example, Langevin, Ben-Aron, Wright, Marchese, and Handy (1988), found that sexual killers were more often diagnosed with sadism, transvestism and antisocial personality disorder. Proulx and Sauvêtre (2007) also noted that sexual killers were more often diagnosed with sadism.…”

“…When looking at apparent motives, Langevin et al (1988) reported that offenders who raped but did not kill mostly sought sexual release, while sexual killers showed elements of both sex and aggression (although the selection criteria for the former group excluded cases where physical violence and sexual attack co-occurred). Chene and Cusson (2007) noted that pre-crime anger (but not necessarily anger during the attack) was indicative of offences culminating in murder.…”

Sadismus

“…So fanden sich z. B. postmortale Verstüm-melungen des Körpers bei 50 % der sexuell motivierten aber auch bei 50 % der nicht sexuell motivierten Tötungsdelikte [4].…”
