At times, a criminal investigation requires a polygraph test. Lie detector tests measure heart rate/blood pressure, respiration, and skin conductivity to determine if an individual is being truthful or deceptive. Control questions are asked to establish a base reaction from the individual before moving into the real questions needing to be asked.

In a criminal case, an individual may be asked to take a polygraph test to further an investigation, admit guilt or prove innocence, or many other reasons. In personal/domestic cases, an individual may be asked to take a polygraph test to prove innocence in cheating on a spouse, marital issues, child abuse, sexual deviancy, theft, and many more situations.

Hamre Polygraph & Investigative handles each polygraph test with professionalism and confidentiality. Our certified polygraph examiner is well-trained with 30+ years of experience and available 24/7 to complete polygraph tests.
