Abstract

Homicide defendants asserting the insanity defense make a volatile combination. Numerous studies review inmates with murder convictions, yet the literature is not rich regarding defendants found not guilty by reason of insanity (NGRI) for murder. This study analyzes 27 years of insanity acquittals in Missouri, finding significant differences between those defendants found NGRI for murder and those found NGRI for other crimes. The get-tough-on-crime initiatives found in the criminal justice system may have led to longer hospital stays post-1996 for NGRI murder acquittees, yet hospitalization lengths increased for all NGRI acquittees, a potential unintended consequence. Policy implications and future research directions are discussed. Abstract published by arrangement with Sage Journals.
