    Clugston Polygraph and Investigative Services offers a variety of investigative services.  

    Either before or after your judgment is obtained, we will locate assets held by your adversary.  These include, but are not limited to bank accounts, bonds, employment compensation, mutual funds, real property, stocks and vehicles anywhere in the world.


    Most everyone finds the need at one time or another to learn more about another person.  This need may be a pre-employment investigation or a pre-marital inquiry.  Background information can be obtained for any legal purpose and in many cases does not require the permission of the person being investigated.

    We are available to investigate any accident, crime, incident or lawsuit.  We will locate and interview witnesses, obtain statements, serve subpoenas, conduct surveillance and gather other evidence in your case.

    Certified polygraph examiners are available to conduct exams for any legal purpose.  Our examiners will come to your site or you may have testing done in our offices. All employment related exams comply with the Federal Employee Polygraph Protection Act of 1988.  We also conduct polygraph examinations in conjunction with marital infidelity investigations.


    Once you have exhausted all your resources to find someone, you may need to contact a professional to get the information you want. Our services are discreet, very thorough and will help you when you've "hit a dead end" in your search.



    You may have concerns about the fidelity of your mate.  Regardless of the nature of your relationship or domestic partnership, you need to be assured that your mate is faithful.  


    Our investigators are available with state-of-the-art equipment to conduct surveillance, either mobile or stationary, on very short notice.  We generally use videotape to document activities that are observed.



    Our investigators use telephone records to assist in the worldwide location of people and to determine their contacts and associates.  Cellular phone records are available for periods of 30, 60 or 90 days, depending on the scope of the investigation.  Besides locating missing persons, this information is used for a variety of purposes including identification of criminal conspirators.
