Behind the Mic at KTSU with Marcus Sullivan: What a Private Investigator Really Does

What made this conversation special was the chance to speak directly to the community we serve. After 17+ years building Terrance Private Investigator & Associates, I’ve learned that the people who need an investigator most are often the ones too unsure to ask. Sitting across from Marcus, I got to pull back the curtain — to explain that this work isn’t about trench coats and long lenses. It’s about getting people the truth so they can make a decision and finally breathe again.

So when Marcus asked me directly what does a private investigator do, I walked through the range of what we actually handle: locating people who don’t want to be found, thorough background checks, lawful surveillance, infidelity investigations, wellness checks on loved ones nobody can reach, missing persons work, and the behind-the-scenes support we provide to attorneys building a case. Every bit of it is done under Texas DPS license A30913601, which anyone can verify through the Texas Department of Public Safety Private Security Bureau. In our experience working hundreds of cases nationwide, almost none of it looks like the movies — and that’s exactly the message I wanted Houston to hear.
