Control Studies: True Crime Behavioral Analysis

J.R. Maren 7 Episodes Aug 16, 2026

Control Studies is a true crime podcast that goes beyond the case — analytical deep dives into the predatory psychology and operational failures of real killers across history and around the world. How they got caught. What broke their methodology. What the serial killer mindset looks like when it's functioning at its most disciplined — and where it fails. Each episode is a behavioral analysis of a real case. No sensationalism. No horror. Just the killer methodology, the failure, and the forensic psychology behind it.
