Traceable Evidence
Exploring the Patterns Behind Human Behavior and Violence
Welcome to Traceable Evidence, the official blog of Dr. S. Lee Funk—a behavioral scientist dedicated to uncovering the psychological and social roots of violence. In this space, Dr. Funk brings decades of research, case analysis, and fieldwork to light, revealing how violent acts are rarely random, but rather the result of complex, traceable factors.
Each post dives deep into the mindset, conditions, and decision-making patterns behind acts of extreme harm—from mass shootings to domestic abuse. Whether examining cultural trends, high-profile cases, or overlooked early warning signs, Traceable Evidence is where science meets social accountability.
This blog is for educators, policymakers, concerned citizens, and anyone seeking to understand not just what happened, but why—and what we can do to prevent it. Because when we follow the evidence, we find insight. And insight leads to change.
