Polygraph Available from Major Case

The polygraph is available to all Detectives and Specialty Units as an investigative tool for all types of cases, including homicide and asset forfeiture. It can be used on criminal subjects, witnesses, or complainants, used to locate evidence or missing persons, or to establish the credibility of informants. The polygraph is not admissible in NYS Courts, but any statements made pre-test or post-test are admissible in court.
