Most of the literature on intimate partner homicide addresses violence between the two partners, spousal abuse, and family violence. There is less focus on the relationship of mental illness, intellectual functioning, and drug and alcohol abuse to these homicides.We investigated this type of homicide in a collection of forensic cases seen by the first author over a period of 10 years. Twenty-eight patients who underwent forensic psychiatric evaluation for heterosexual intimate partner homicide from August 1993 to June 2003 were studied using a retrospective case review methodology.We found that firearms were used as the method of killing more often by females than by males.We also compared method of killing with substance abuse and intoxication at the time of the homicide. Educational status indicates that this group of accused perpetrators is functioning at higher intellectual levels compared with a previously studied sample of filicides. We also found significant presence of serious mental illness in our sample of accused perpetrators of heterosexual intimate partner homicide.

The forensic psychiatric examiner often encounters defendants who deny memory for their offense. Past research proposes a variety of factors to account for offense amnesia. To date there have been few systematic studies of offense amnesia in relation to psychiatric diagnosis, either alone or in combination with other known factors such as substance use and malingering. We studied 53 pretrial felony defendants who had been referred for psychiatric examination; 40% claimed amnesia for their offense. Examinees with psychotic disorders in general, and schizophrenia in particular, were relatively less likely to claim amnesia than were examinees with other diagnoses. Substance use at the time of the offense and associated substance use disorder diagnoses were positively associated with offense amnesia. Malingering diagnosed by general clinical criteria was a poor predictor of amnesia claims. These data suggests that two prominent reasons for referral for forensic psychiatric evaluation include the presence of psychotic symptoms and claims of amnesia for the offense.

We examined the reactions of 17 male inpatients on a secure psychiatric unit to television news coverage of the September 11 attacks. All had psychotic diagnoses. We hypothesized that self-exposure and affective response to the news coverage and use of social support would be influenced by predominance of negative symptoms. Additionally, we examined for the emergence of common stress symptoms and exacerbations of psychosis. Results showed a dose-response relationship between amount of viewing and magnitude of response to the coverage. Anger was the emotion most clearly tied to coverage exposure and the other response variables. A wide range of stress symptoms was reported. Hypotheses concerning the influence of negative symptoms were partially supported. A significant minority of the patients disclosed exacerbation of psychotic symptoms in response to the attacks. Patients who reported a negative emotional reaction were more likely to talk to others about the attacks, but social contact did not predictably lead to affective relief.
