Destructive hostility: the Jeffrey Dahmer case. A psychiatric and forensic study of a serial killer.

We were involved as forensic experts in the case of the serial killer Jeffrey Dahmer. We discuss the scene and victim autopsy findings, with a brief consideration of the basic emotion of hostility. These findings support the thesis that at the basis of this serial killer's behavior were primary unconscious feelings of hate that he had channeled into a sadistic programmed destruction of 17 young men. The interview of the serial killer, the photographic scene documentation, and the autopsy findings stress the ambivalent homosexuality of the killer, his sexual sadism, his obsessive fetishism, and his possible cannibalism and necrophilia.

Ro15-4513 antagonizes depression of open-field horizontal activity by ethanol in rats.

The imidazobenzodiazepine, Ro15-4513, has been shown to antagonize some of the behavioral effects of ethanol (ETOH). In rats having relatively little experience in the open field, the actions of ETOH (0.75 g/kg IP), Ro15-4513 (1.25 mg/kg and 2.5 mg/kg, IP), and Ro15-4513 in combination with ETOH were measured on horizontal activity. Rats receiving ETOH showed a significant depression in horizontal activity. Doses of Ro15-4513 given alone produced no significant differences in activity from baseline levels. Rats pretreated with Ro15-4513 prior to receiving ETOH, however, showed a significant attenuation of the ETOH induced depression of activity. These results indicate that Ro15-4513 is effective in attenuating the depressive effects of ETOH in the open field in rats having little experience in the apparatus.
