Voice-stress analysis test nets small-town murder suspects (Pt. 1) Voice-stress analysis test nets small-town murder suspects

California, Roseville P.D. – Analyst/Det. Charlie Veilleux reports that his first use of the CVSA following his graduation from the Certified Examiners Course conducted by the NITV was to reopen a five-year-old homicide that had been classified as a Cold Case. A young woman had been brutally murdered and a viable suspect was quickly developed. He denied any involvement and passed a polygraph exam and was dropped as a suspect. Since the subject had suffered an aneurysm and two brain surgeries in the five years since his last polygraph, another polygraph was not considered. The subject was offered a CVSA exam and agreed to take the test. The exam indicated that he was the killer and using the interrogation techniques taught by the NITV, detectives obtained a full confession with details that only the killer would know.
