If you want a private investigative agency that can give you the one on one attention that you desire, Truth Investigations of Princeton may be right for you. Regardless of whether you are a business owner or a person in need of investigative services, your case is important to you. Our focus is on conducting investigations. Many agencies focus on security or alarms; we conduct investigations only. Experience and knowledge matters when you are considering which investigations agency you should hire.


You should know all the facts before you hire an agency, after-all; we are talking about an occurrence in your business or your life that drove you to seek help! Hiring a private investigator is not always the right answer to your problem. If I don' t think you should hire an investigator, I will tell you truthfully; don't do it!  When I was in law enforcement I hated when I saw people who came to agencies in the judicial system with questions and employees treated them like they should know the answers. I understand, I get it. You came seeking answers. I can't offer legal advice, but we can work together to find the answers you need to make an educated decision on what your next steps need to be.


I am Walter Martin, owner of Truth Investigations of Princeton. I retired from the Smithfield Police Department with over 23 years of law enforcement experience. I spent 16 of those years as an investigator. I served as a Master Officer, Detective, Detective Sergeant, Lieutenant on both patrol and investigations in my career. I have extensive investigative and courtroom experience. My courtroom experience includes civil and criminal cases in Federal and State Court.


I am responsible for your case, your case won't be given to a rookie, but to an investigator that Chiefs and District Attorneys have shown their confidence in. I am not bragging, I am just repeating what I was told. Our address is P. O. Box 362 Princeton NC 27569. Our business hours are Mon- Fri 9 AM - 5:30 PM. Our telephone number is (919) 936-0900.
