Zone 7 with Sheryl McCollum

Introducing: Zone 7 with Sheryl McCollum

In this episode of Zone 7, Sheryl McCollum is joined by retired Secret Service agent and polygraph examiner Brad Beeler to discuss what 25 years of talking with suspects, witnesses, victims, and some of the worst offenders taught him about getting people to open up and tell the truth. Brad covers why trust has to come before truth, the damage one accusatory word can do to a conversation, and how respect gets people to open up faster than pressure ever will. He also shares practical signs that may indicate deception, why sometimes the best thing you can do is stop talking and listen, and how the same principles he relied on in high-stakes investigations can help anyone become a better communicator.



Highlights:

(0:00) Sheryl McCollum introduces retired Secret Service agent Brad Beeler and the moment she saw his commitment to a cold case firsthand

(5:30) Why making people feel heard, respected, and genuinely listened to can change a conversation

(8:00) The worst thing you can call someone when you are trying to get the truth

(10:00) Why Brad aims to listen 80% of the time and what investigators can learn when they stop talking

(15:45) “Create a space where truth feels safe enough to emerge”

(17:45) Why even the worst offenders have to be treated with respect if investigators want answers

(21:30) How Brad evaluates possible deception without relying on a single supposed ‘tell’

(23:15) Turning a story into a yes-or-no question to test whether someone will stand behind what they said

(24:30) Delayed answers, vocal inflection, overly specific responses, and qualifying words that may signal deception

(27:15) Why respect matters more than rapport when you have little in common with someone

(28:30) What protecting foreign dignitaries taught Brad about professional respect across cultural and political divides

For more than 45 years, the Verville family has never stopped searching for Kevin, who they believe has no idea he was ever taken. They believe someone listening today could recognize Kevin, help identify the woman responsible, and finally reconnect him with his family.

In this episode of Zone 7, Sheryl McCollum is joined by retired Las Vegas Police Sergeant Jenn Benjamins for a look inside undercover police work. Jenn explains what separates basic surveillance from true deep cover, where officers must build believable identities, speak the language of the street, and think fast enough to avoid being “made.” She discusses prostitution stings, pimp culture, human trafficking, and why undercover work requires a specific kind of officer. Jenn also shares how she now carries that experience into Covert Blue LLC, her law enforcement training company, where she helps prepare officers for undercover operations, investigations, leadership, and the realities of the job.

(4:15) How officers avoid getting “made” while working prostitution and narcotics cases

(8:00) Why only a small percentage of officers may be suited for undercover assignments

(11:15) The importance of knowing street talk, pricing, roles, and expectations during vice investigations

(16:00) Sheryl and Jenn discuss the kind of money that moves through high-end escort work in Las Vegas and why leaving is often more complicated than people assume●

(19:00) Jenn explains the different types of pimps, including Casanova and gorilla pimps, and how violence and gang culture changed the prostitution landscape

(22:30) Major events like the Super Bowl and the World Cup, the “circuit,” and how large

gatherings can bring increased prostitution, trafficking, and related crime into host cities

(29:30) Jenn talks about dressing the part, avoiding entrapment concerns, and building a believable undercover appearance

(35:15) Sheryl honors Jenn’s law enforcement service and her work training future undercover officers through Covert Blue LLC
