When the bullets started flying during the Waco siege, Mary Daugherty wasn’t in an office or watching from a screen. She was in the field, pulling women and children to safety while chaos unfolded around her. That moment, like so many others in her career, left a lasting impact. It shaped how she sees the role of an investigator, not just as someone who asks questions but as someone who earns the right to hear the truth.
Over the years, Mary’s mission shifted from enforcement to education. Today, she’s known not just for her field experience but for her unmatched ability to teach others how to conduct better, more human-centered interviews. At the heart of her approach is a technique that most departments have heard of but few truly understand. It’s called the Cognitive Interview.
Why Most Interviews Fall Short
Mary has seen it all. Traditional interviews often rely on rapid-fire questions, closed body language, and an unspoken power dynamic. That approach might get compliance, but it rarely gets clarity. And it definitely doesn’t build trust.
After years of watching cases fall apart due to poor communication or incomplete information, Mary started asking the deeper question. How do we help people remember what matters without contaminating their memories or backing them into a corner?
The answer, she found, was rooted in psychology.
The Cognitive Interview: A Smarter Way to Ask
The Cognitive Interview is built around a simple truth. Memory doesn’t work like a file cabinet. It’s fluid. It’s sensory. It needs the right environment to come forward.
This method uses science-backed techniques to help people recall events more accurately and in greater detail. It’s not about leading someone. It’s about guiding them. You build rapport. You ask open-ended questions. You give them space to remember, not just respond.
Mary teaches the Cognitive Interview the way it was meant to be taught, not as a checklist but as a mindset.
Why Mary’s Voice Cuts Through the Noise
Plenty of people can recite the theory. Mary lived it.
She understands fear, not just from those being interviewed but from the investigators sitting across from them. She’s worked cases where one wrong assumption could unravel months of progress. She’s also seen how the right question, asked at the right time, can change everything.
Her approach is clear. You don’t just need a better interview. You need a better connection.
That’s what she teaches, not just to police departments but to compliance teams, corporate investigators, and leadership professionals who need to uncover the truth in high-stakes conversations.
Leadership Starts with Listening
Mary doesn’t treat interviews as a formality. She sees them as a chance to lead. To create trust where there is none. To listen with intent. And to walk away with not just answers but the right ones.
She’s spent her career showing that the most powerful tool in any investigator’s kit isn’t force. It’s trust. And trust is built one question at a time.
