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

In this follow-up episode of Zone 7, Sheryl McCollum is joined by retired NYPD detectives Tom Smith and Dan Murphy of Gold Shields to take an investigative look at the unresolved case of Stevie Bates. After revisiting Stevie’s 2012 disappearance and the 2020 discovery of her remains in Glendale, Queens, Sheryl, Tom, and Dan discuss the key questions that remain. They examine why the deleted Facebook messages raise red flags, the legal issues surrounding a squatted property, and why the discovery of Stevie’s remains, wrapped in a blanket and disposed of five feet below ground, points to someone who knew her, knew the area, and likely had help. They also urge anyone with information, no matter how small it may seem, to come forward and help bring resolution to the case and justice for Stevie.
