Psychiatric aspects of criminal homicide in Nigeria
Abstract
OBJECTIVES: To investigate the Psychiatric aspects of homicide in Nigeria, and, the psychosocial and forensic background of homicide offenders in Nigeria; to determine the role of the mental health services in the disposal of the accused by the criminal justice system.
DESIGN: Retrospective study, involving interview of homicide convicts and, the scrutiny of court and prison documents for relevant clinico-forensic data.
SETTING: Federal Prison, Jos, Nigeria.
RESULTS: One hundred and eighteen subjects participated in the study. Psychotic disorder (mainly paranoid schizophrenia) and alcohol intoxication accounted for the offenses of 28 (24%) accused. Amnesia for the events occurred in psychotic offenders. Psychiatric services were underutilised in the trial and disposal of the accused. Marked psychosocial maladjustment in offenders was suggested by a high rate (45%) of substance use disorders predating the homicide events. Thirty three (28%) offenders had dysfunctional family circumstances. Eighty six per cent of the accused were first time offenders. Adverse life events, predominantly in relation to the victims, were reported by 33 (28%) of the accused in the month predating the events.
CONCLUSIONS: Psychiatric disorders and substance use are significantly involved in homicide events in Nigeria. There is a need for close liaison between the psychiatric and criminal justice systems, in the disposal of all homicide accused. A continuing study of homicide in Nigeria is recommended, to bridge the gap in our present level of knowledge.
