Psychopathic and neuropathic pathways to homicide: Examination of harris and rice's two-path model of criminal violence in homicide

The present research examined a two-path model of homicide defined by psychopathic and neuropathic pathways. Twenty-six forensic psychiatric inpatients found not guilty due to reason of insanity of homicide or attempted homicides were assessed. A large number of variables derived fromstandardized neuropsychological psychometric assessment, actuarial and structured risk assessment tools and structured interviews were analysed. Qualitative comparative analysis (QCA) and the Answer Tree program showed that independence of the two pathways was observed from a nomothetic analysis with individual variations understood by the complex variable relationships at an idiographic level.
