Parricide and homicide NGRI offenders: How do they differ?

The article focuses on the forensic psychiatric characterization of perpetrators of parricide—defined as the homicide of a parent by their offspring—who were found not guilty by reason of insanity (NGRI) in Northern Greece. The study analyzed 52 NGRI patients hospitalized between 2015 and 2020, comparing 21 parricide offenders with 31 offenders who committed homicide against nonparent victims. Findings indicate that parricide offenders were predominantly unmarried males in their thirties diagnosed mainly with schizophrenia, often with prior mental health service contact, treatment nonadherence, substance abuse history, and prior violent behavior; all parricides involved sharp weapons and occurred in private residences. Compared to the control group, parricide offenders showed higher rates of voluntary hospital admissions and elevated risk of future violence, underscoring the importance of early intervention, family support, and comprehensive risk assessment to prevent such incidents.
