"Having the pleasure of working with Greg while he was a Lieutenant for the Texas Department of Criminal justice, I can say with confidence that he is the cream of the crop! Greg is a professional investigator who was affectionately nicknamed "Columbo" by his peers. This was due to his uncanny ability to get to the truth during the course of an Investigation.

My 14 year old child who has a medical condition that requires constant medical care, ran away. Greg Tucker was able to locate and to get our child back to our care within 12 hours and over 300 miles away. Greg is a professional and we owe a debt of gratitude for his service.
