Polygraph Services

A professional polygraph examination often called a "lie detector test" is the best available technology and usually the only tool available to verify the truth after the fact. Law enforcement, intelligence agencies, probation and the courts are the largest single subscribers, however, more and more couples with domestic relationship or private family issues are common. Business owners use polygraph in employee theft investigations and attorneys often request a polygraph for clients with pending criminal charges. The so-called computer voice stress analyzer is a "toy" and not a polygraph and is illegal in Texas for the purpose of determining truth of a specific statement. All of our polygraph examiners are licensed professionals with years of experience and graduates of accredited schools certified by the APA (American Polygraph Association). They have additional training in court-ordered sexual offender testing as set out in the guidelines by the Joint Polygraph Committee on Offender Testing guidelines.

Employee Theft Polygraph


The Dallas Lie Detectors staff is well-versed in how to properly administer employee theft polygraph examinations. It is important that a business client uses a professional firm that will take the time to guide you in this procedure. This is a low profile (friendly) process with the objective of verifying the truth and reporting accurate statements to the employer. Polygraph is often one of the only venues left to clear a loyal employee. Incidents to be examined includes monetary and inventory theft, industrial sabotage, selling sales leads or theft of intellectual property. Business owners usually have more than one employee with access and for which they may have reasonable suspicion and each one will be thoroughly examined before a comprehensive written report of findings is delivered to the designated executive.
