Brandon Andres Green sits down with Eric Cullen of Cullen Investigations, one of Tulsa’s go-to investigators for high-stakes cases, to talk about private investigation, criminal defense work, wrongful convictions, and what it takes to build truth that can survive court. A good investigator is not chasing gossip. They are gathering facts, testing stories, protecting evidence, and helping people make decisions when the stakes are painfully high.
Eric shares how Cullen Investigations grew from a one-person agency in 2004 into a full investigative team serving clients in Tulsa and beyond. We talk about high-level litigation support, trial preparation, criminal defense investigations, and why understanding the rules of evidence matters just as much as instinct.
We also dig into Eric’s work on wrongful conviction cases, including career experience connected to nine exonerations, ongoing commutation efforts, and new cases that come in from across the country. He explains why many clients arrive during one of the worst moments of their lives, and why professionalism, discretion, and clarity matter when families are trusting someone with a sensitive case.
Eric also shares the deeply personal turning point that shaped his mission: investigating the death of his best friend in Tulsa police custody and helping push the case toward real policy change. From intense custody disputes to alleged elder fraud, we explore what situations lead people to hire an investigator and what families should look for before choosing one.
If you care about justice, accountability, criminal defense, court-ready evidence, or how facts actually get proven, this conversation offers a rare look behind the curtain. Eric also previews a new service designed to connect people with the right attorney or specialist, along with his upcoming memoir and future podcast based on the cases.
