Today we explores the investigative mind of the legendary CSI Paul Holes. In a one-on-one with Detective Dave, we journey back over a career that started in a forensic toxicology lab and led to his groundbreaking cold-case work hunting serial murders like the Golden State Killer. Along the way, Paul reveals how he deals with death, what he means when he says “real crime” instead of true crime, and the impact years of working grisly crime scenes has had on his mental health.
