The Parkland School Shooter:: Culpability and FASD (SpringerBriefs in Criminology)

This brief explores the justification of the death penalty, using the 2018 Marjorie Stoneman Douglas High School shooting in Parkland, Florida, as a case study. The authors argue that when an offender’s impairments severely impact their ability to make rational decisions, the death penalty is unjustified, regardless of the crime's severity. The book examines the case of Nikolas Cruz, the school shooter diagnosed with fetal alcohol spectrum disorder (FASD), including: 

• The nature of FASD, how it was measured, and how it manifested in Cruz.
• The impact of FASD on Cruz’s adaptive functioning.
• The concept of “psychiatric overshadowing” and how it led to the oversight of Cruz’s FASD and associated brain damage by many mental health experts.
• The broader implications of FASD, with a recommendation to expand death penalty exemptions to include disorders equivalent to intellectual disabilities (ID).

By focusing on the highly controversial Cruz case, the authors—key experts from the trial—offer insights into FASD and its often-overlooked role in determining criminal responsibility and sentencing. This book is essential for forensic psychologists, psychiatrists, mental health professionals, FASD/DD specialists, researchers, and legal professionals involved in death penalty defense work.

Natalie Novick Brown is a forensic psychologist in the Seattle area and courtesy Clinical Assistant Professor at the University of Washington School of Medicine. She co-founded “FASD Experts,” the leading multidisciplinary group that conducts evaluations of FASD defendants in capital cases. Those capital cases included the Parkland shooter Nikolas Cruz, for whose legal team she compiled a definitive social-developmental history and conducted adaptive behavior assessments. She has evaluated several hundred adolescents and adults with FASD, trained graduate students and psychologists on the subject, testified in capital murder cases in nearly 20 states, and authored over 40 peer-reviewed journal articles and book chapters dealing with FASD. Her edited book Evaluating Fetal Alcohol Spectrum Disorders in the Forensic Context: A manual for mental health practice (2021) is the most authoritative book on the subject. She, along with the other two authors, was elected to the Hall of Fame of FASD United, formerly the National Organization for Fetal Alcohol Syndrome. She was retained as a defense expert in the Parkland case and evaluated Nikolas Cruz but did not testify.

Stephen Greenspan is a developmental psychologist who is Emeritus Professor of Educational Psychology at the University of Connecticut, where he was director of the A. J. Pappanikou Center for Developmental Disorders. He is the most-cited authority in the Intellectual and Developmental Disability (IDD) section of DSM-5 and DSM-5-TR and has authored or co-authored nearly 100 scholarly publications pertaining to the IDD population, with much of his recent work involving forensic issues pertaining to FASD and its IDD-equivalence. He has testified in many criminal cases (mostly homicides) involving offenders with possible IDD, including FASD. The focus of much of his work is on social incompetence, particularly gullibility and foolishness (lack of risk-awareness) as defining features of IDD, and he has written the only comprehensive books on both of those topics: Annals of Gullibility (2009) and Anatomy of Foolishness (2019). He was retained as a defense expert in the Parkland case but did not testify.

Karen Steele is an attorney based in Salem, Oregon, whose practice involves complex/capital cases with an emphasis on neurodevelopmental issues (e.g., FASD) and late adolescent brain development. Specifically, she identifies the consequent behavioral attributes, needs, and vulnerabilities stemming from those conditions as well as their forensic implications, using that information to deepen the court’s understanding of her clients’ disabilities.  A sole practitioner, Karen’s practice interests flow from the lives, conditions, and contexts of her clients, including the 1987 capital prosecution of a youth who was 30 days past his 18th birthday and now is in his mid-50s.  Outside of individual case contexts, Karen consults, presents, and writes on the relevance and treatment of neurodevelopmental conditions in court and correctional settings and on ethical and practice standards in investigating, integrating, and presenting neuroscientific information, which include Forward-Thinking Mitigation and excuses for not presenting information, such as “Double-Edged Sword” evidence.
