Variables examinated in the analysis include age and sex of perpetrators and victims, type of weapon used, location of the homicide and results of toxicological investigation. The sex of offenders is predominantly male (M:F =4:1) and the victims were mostly female (M:F = 2:5). Firearms were the predominant method of Death in both homicides and suicides Relationships between offender-victim and the psychodynamic determinants leading upthe onset of homicides and suicides is then analyzed. Data were compared with the national and international scientific literature. The data emerging from the case histories were compared with those of autopsy cases of the same Unità di Medicina Legale relatively to the case of murder-suicide in the period 1983-2002. The comparison has partially confirmed the data collected from the previous survey, presenting some differences with respect to the weapon used and the type of interpersonal relationship between perpetrator and victim.
