This episode explores the disturbing trend of mass shootings committed by individuals with histories of substance abuse. We'll examine case studies where perpetrators of horrific acts of violence were found to have toxic levels of drugs or alcohol in their systems, from the Columbine High School massacre to the Orlando nightclub shooting. Forensic toxicologists, criminologists, and mental health experts analyze the potential causal links between intoxication, mental instability, and the decision to commit mass murder. Listeners will gain a deeper understanding of the complex interplay between chemical, psychological, and sociological factors that can transform troubled individuals into mass killers.
