What is a Polygraph?

One of the key investigative tools that an experienced investigator can have is the polygraph, or lie detector. The lie detector is a truth verification device that, when used in conjunction with a structured, tactful, and professional interview, can detect if a subject is being truthful regarding his statements or is potentially misleading the investigator.

911 Detective can serve your lie detection needs in the following areas:

Criminal Lie detection

Criminal polygraph testing is usually one in which the subject is either accused of a crime or has already been convicted of a crime. There are prosecutorial polygraph examinations in which there is a strong effort to ascertain a confession if indeed the subject fails the polygraph examination. There is the defense polygraph examination, where obviously if the subject shows deceptive criteria on the polygraph examination, there is not usually a strong effort to elicit a confession.

Civil Lie Detection

These examinations generally are examinations that involve business issues in which there is a search for either an internal theft situation or some other issue that has called into question the veracity of the subjects involved but is not deemed to be criminal in nature.
