In this episode of Zone 7, Crime Scene Investigator, Sheryl McCollum and Phil Chalmers come together for pt. three of Preventing a Serial Killer. Former Detective David Quinn sits down with Aeman Presley for the first time since their unforgettable six-hour interrogation. For Quinn, this wasn’t just another case; it was the final chapter of a 30-year career in homicide, one that forever changed how he views justice, redemption, and even the death penalty. He reflects on the spiritual moments that guided the investigation, calling them nothing short of divine intervention. Aeman opens up about the pain and trauma of his upbringing, the influences that shaped his descent into violence, and the regret he carries every day. Together, they discuss the human side of tragedy, how community, media, and personal choices intertwine to create paths that sometimes end in darkness, and how, even then, healing and understanding are still possible.
