Cold Cases Solved

37-Year-Old Cold Case Broken With the CVSA

 Illinois, Coles Co. Sheriff’s Dept – CVSA Analyst D/Lt. Stephen broke a 37-year- old Cold Case Homicide that was solved utilizing the Computer Voice Stress Analyzer (CVSA).  A young woman was brutally murdered in 1980 and although several suspects were developed, there was never enough evidence to make an arrest.  Following her department’s acquisition of the CVSA 37 years later, D/Lt. Stephen called one of the suspects, who was now 70, and requested his help in going through a box of evidence to see if they could come up with any new leads.  The suspect agreed and while they reviewed the evidence, D/Lt. Stephen asked the individual if he would take the CVSA exam to screen him out of any further suspicion.  He agreed.   After the exam D/Lt. Stephen let him see the CVSA charts, which clearly indicated deception, and he confessed to murdering the young woman 37 years ago.  Without the CVSA, the murder would have never been brought to justice and the family would never have had closure.

CVSA Solves Cold Case Homicide 7 Years after Suspect Passes Polygraph

Utah, Pleasant Grove P.D.- CVSA Analyst/Det. Lt. Britt Smith reports that a grant from the Internet Crimes Against Children (ICAC) Task Force provided the funding for his department to purchase the CVSA. Lt. Smith states that just days after returning from training on the system, they re-opened a rape case involving minors that had occurred 7 years ago. The case had been closed months prior because the suspect had denied the abuse in a previous interview and the case lacked physical evidence, due to a delayed report.

The suspect had been arrested years previous for other non-related sexual offenses. During court ordered treatment the suspect was given three polygraph examinations in an effort to disclose further victims. According to the suspect he passed all three polygraph examinations. This victim and details about this crime were never disclosed during treatment. Detectives re-opened the case with the intent of using the newly acquired CVSA as an investigative tool. The suspect readily agreed to take a CVSA exam, and bragged to Lt. Smith that he would have no trouble passing. The suspect failed the CVSA and when he was shown the charts from the exam which clearly showed deception, the suspect confessed. Lt. Smith states that the department has solved many crimes with the CVSA since then and that the CVSA has saved them time and money and, in his experience, has never been wrong.

CVSA Solves Cold Case 14-yrs-after Suspect in Homicide Passes Polygraph

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 Defense Barrier Removal® interrogation techniques taught by the NITV FS, detectives obtained a full confession with details that only the killer would know.

CVSA Solves a Cold Case Homicide by Analyzing a Taped Interview of a Suspect that had Passed the Polygraph 6 Years Ago

Detective Gordon Chase of the Cocoa Police Department was assigned a cold case regarding the homicide of a young woman six years prior. During the initial interview, two suspects were cleared when they passed voluntary polygraph examinations. Detective Chase discovered their tape-recorded statements and reexamined them for deceptive answers. This would be the key to unlocking the mystery of who brutally murdered an innocent woman.

Detective Chase was also a Certified CVSA Examiner, so he analyzed the suspects’ recordings using the Computer Voice Stress Analyzer® (CVSA®). Using this truth verification technology—which is highly effective with both live subjects and recorded material—he ruled out one suspect. The recorded statement of the other suspect indicated deception when she was asked about committing the murder. He was able to locate this woman, and she was given a CVSA examination in person. Again, the charts showed deception. Forty minutes of questioning led to the suspect admitting she committed the murder and providing information on how she disposed of the murder weapon.

Cold Case Solved by the CVSA after 3 Suspects Polygraphs were Inconclusive

Raleigh County Sheriff’s Office, WV.  – Analyst D/Cpl. Jim Bare reports that the 14-month-old homicide of a security guard at a local mine went unsolved with no suspects and was considered a Cold Case. Eventually three suspects were named and D/Cpl. Bare conducted CVSA exams on each and cleared them of involvement.  Later, three additional suspects were developed and all were run on the polygraph in another jurisdiction. All three polygraphs were inconclusive. All three suspects were requested to submit to the CVSA and two of the three showed up for their exams. After the first individual was tested, the CVSA indicated that he was present when the homicide took place despite his insistence that he was not. After being shown the deceptive charts, the suspect confessed that he was there and his involvement in the homicide. The second suspect came in and admitted that he was a witness to the crime but did not participate. Following his CVSA exam, it was clear that he was the shooter. He was then interrogated and finally confessed to shooting and killing the security guard. Without the CVSA, this case may never have been solved.

Springfield Township P.D., OH. –. Analyst/Det. Pat Kemper reports that he recently was asked to conduct a CVSA examination on two parents and a baby-sitter concerning a six-month-old child that had been seriously abused.

However, the prosecutor in the case informed the defense attorney that they would require the babysitter to take the CVSA to receive any consideration. Following three deceptive charts, the babysitter admitted that she had caused the serious injuries to the baby. She plead guilty as charged and was sentenced to serve time in prison. Det. Kemper states that he has found many cases where the polygraph and CVSA have disagreed, all ending with the CVSA having the correct charts and the correct analysis.
