Criminal Minds follows the FBI's Behavioral Analysis Unit as they work to profile serial killers and track them down. The BAU team investigates and captures some of the most dangerous criminals in each episode. As a police procedural show, Criminal Minds sees many character deaths over 15 seasons. Every example is undoubtedly saddening since it represents another human being whom the BAU fails to save despite the impossible circumstances and their dedication to their jobs.
