Zone 7 with Sheryl McCollum

Introducing: Zone 7 with Sheryl McCollum

https://api.omny.fm/orgs/e73c998e-6e60-432f-8610-ae210140c5b1/clips/c4ce65c3-7fe3-4d81-a4bb-af6a0133fb85/transcript

Human trafficking investigations rarely look like abduction stories, and the biggest failures often start with a single mistake: mislabeling the victim. In this Hall of Fame Series installment of Zone 7, Sheryl McCollum is joined by Maurice Edwards, a 2023 National Law Enforcement Officer Hall of Fame inductee. Together, they clarify what trafficking looks like in the United States, explain why prosecutors and victim advocates belong in the earliest stages of an investigation, and challenge the language and assumptions that can derail a case. Sheryl and Maurice emphasize a victim-first standard: when a child is being bought and sold, the work begins with protection and recovery.



Highlights:

• (0:00) Sheryl McCollum introduces Maurice Edwards and his career in missing-child and child sex trafficking investigations

• (2:15) Maurice’s current role supporting child sex trafficking investigations at the National Center for Missing and Exploited Children

• (3:45) What drew Maurice to trafficking work through missing-child cases and pattern recognition

• (6:45) The first trafficking case, first convictions, and the task force model that followed

• (9:00) Why prosecutors must be embedded early to build cases that survive court

• (11:00) Legal precision at the scene, and why Sheryl insists a teamwork mindset makes cases stronger

• (13:45) Misconceptions that derail trafficking cases and why language shapes how  victims are treated

• (18:45) The cases that stay with Maurice: child deaths, coercion, and forced substance abuse tied to exploitation

• (21:25) Carrying the work home: Maurice on emotional boundaries and staying steady in child sex-crime investigations

• (28:30) Technology’s role in trafficking and the investigative reality of criminals adapting to new tools

• (32:15) Practical ways the public can support prevention and a victim-first response

• (33:15) The comparison that exposes the double standard in how minors are treated in commercial sex settings

• (38:00) Closing reflections on service, humility, and credit not being the goal

The Zone 7 Hall of Fame! Maurice Edwards on Fighting Human Trafficking: The Victim-First Approach

https://api.omny.fm/orgs/e73c998e-6e60-432f-8610-ae210140c5b1/clips/8a2ee90a-c565-4428-af72-b3c80130dd15/transcript

Nearly four decades after the Colonial Parkway murders first shocked Virginia, new DNA links have expanded the known scope of the case while raising questions about investigative accountability.

In this episode of "Zone 7," Sheryl McCollum is joined by Bill Thomas, whose sister Cathy Thomas was one of the original victims, and Kristin Dilley, his long-time investigative partner and co-host of the podcast, "Mind Over Murder."

They walk through the latest DNA identifications tied to Alan Wade Wilmer Sr., the procedural barriers that keep his profile out of CODIS, and the growing divide between state-level momentum and federal inaction.

Their discussion centers on what happens when evidence advances while communication and action stall.

In January 1981, during a severe winter storm, Lonene “Lonnie” Rogers disappeared from her home in rural Pennsylvania, leaving behind her children, her car, and no clear explanation for how she could have survived the conditions.

In this episode of Zone 7, Sheryl McCollum speaks with Lonnie’s daughter, Alison Duiker, about the final hours before the disappearance, the instability that followed, and the long search for answers that began when Alison was just five years old.

Joined by clinical hypnotherapist Monica Miller, their conversation revisits the timeline of that night and the challenges of examining long-dormant cases when physical evidence is scarce.
