Documentary deep-dive into the Denver serial killer(s) case spanning 1976-1990+. DNA breakthrough in January 2022 identified Joe Michael Irvin as killer of at least 5 women (1979-1981), who took his own life. However, police believe 6+ serial killers were active; investigation narrowed 27-50+ suspected victims to 16 official cases. Covers detailed victim profiles (ages 12-52), investigation methods, patterns (sex workers, hitchhikers, runaway minors abducted from bars/parties), body disposal (spread legs, posed, dumped near I-70), and systemic investigative failures (crimes not linked until 2008, 32 years after spree began). Episode structured chronologically across multiple victims.
