San Antonio, Texas – 14 April, 2026 – Dr. Phillip D. Clingan, a distinguished criminologist, professor, and behavioral analyst, has released a compelling three-book series that is reshaping the landscape of true crime literature. Moving beyond dramatic storytelling, the series introduces a structured, evidence-based approach to analyzing serial offenders, offering readers a deeper and more accurate understanding of criminal behavior.

A Data-Driven Approach to Understanding Serial Killers Through Science, Psychology, and Behavioral Analysis

A New Era in True Crime and Criminological Research

True crime remains one of the most widely consumed genres worldwide, yet much of its content relies on speculation and entertainment-driven narratives. Dr. Clingan’s work stands out for its focus on forensic accuracy, behavioral science, and psychological interpretation.

Each book applies a consistent analytical framework, including chronological case reconstruction, a clear distinction between modus operandi and signature behaviors, victimology, and analysis of detection failures. This method allows readers to evaluate patterns across cases and to understand how investigative gaps have historically enabled offenders to evade capture.

Dr. Clingan’s vision is clear:

“To transform how society understands violent offenders by replacing speculation with structured analysis, and by equipping readers, students, and professionals with knowledge that is both scientifically grounded and practically applicable.”

His work is designed not only to inform but to enhance investigative thinking, academic learning, and professional practice.
