The Demonic Defense: A Forensic-Legal Analysis of Possession Claims in Criminal Proceedings Through the Psychopossession Framework
Year: 2026
Type: article
Abstract: This mixed-methods study examined the phenomenon of demonic possession claims as criminal defenses through the lens of the Psychopossession theoretical framework. Despite increasing intersection of religious beliefs and legal proceedings, no systematic analysis has evaluated how possession-related defenses are adjudicated or what factors predict their success. This study addressed this gap by analyzing 37 criminal cases involving possession defenses from 1974 to 2022, drawn from publicly available court records, legal databases, and archival sources across the United States and international common law jurisdictions. Quantitative analyses included descriptive statistics, chi-square tests, and logistic regression, while qualitative analyses employed thematic analysis of judicial reasoning and defense strategies. Results revealed an overall defense success rate of 27.0%, with significant variation based on case characteristics. The Spectrum of Possession by Evil (SPE) classification demonstrated strong predictive validity for legal outcomes (χ² = 13.28, p < .001, Cramér's V = .599). Dissociative features emerged as the strongest predictor of defense success (OR = 23.0), while post-arrest claim emergence negatively predicted favorable outcomes. Expert testimony was present in 94.6% of cases, with psychiatric experts associated with higher success rates than theological experts. The study validated the forensic applicability of the Psychopossession framework and generated evidence-based guidelines for forensic assessment of possession claims. Findings have implications for forensic evaluators, legal professionals, mental health practitioners, and policymakers navigating the complex intersection of religious experience, mental disorder, and criminal responsibility.
