In this episode of Blue Leadership, Dennis sits down with Nuno Tavarez, a retired investigative lieutenant from the Placer County DA's office, nationally recognized cold case detective, and faculty member with the MS LEPSL program at the University of San Diego. With a career spanning 27 years in law enforcement, Nuno shares his experience investigating homicides and serious crimes, including the cold case of Christie Wilson, which was first featured on the CBS show “48 Hours” in 2021, and again in 2023 after Christie’s body was finally found. In addition to giving his unique perspective on the investigative techniques of that case, Nuno also discusses the science-based interview techniques (SBI) that are transforming police interrogation methods, as well as other highlights from the 80-hour course he teaches for new homicide detectives. As a recently retired law enforcement professional who remains active as an instructor, Nuno also shares his tips for staying engaged and connected in retirement.  This episode is captivating from beginning to end, especially for anyone working in homicide, involved in interviewing or nearing retirement.
