Utah, West Valley City P.D.Analyst/Det. Steve O’Camb reports that the upscale community was shocked when a woman was found brutally murdered in her home near Salt Lake City.  There were no suspects, no motive, and police were left to screening those with access to the home.  One such person was seen on a TV news program consoling and shaking hands with the victims husband.  The individual turned out to be an 18 year-old next-door neighbor.  He was not considered a suspect but because he lived in close proximity to the victim’s house, he was asked to take a CVSA exam.  In Det. O’Camb’s opinion, the charts indicated that the subject was involved in the murder.  A ‘cold call’ of the charts was then requested.  Analyst/Det. Mike Fossmo conducted the ‘cold call’ and agreed with Det. O’Camb’s call.  After being shown the charts and questioned further, the subject finally admitted that he committed the murder.  He then led detectives to the murder weapon.

Alabama, Vestavia Hills P.D.  – Analyst/D/Lt. Rick Miller reports that the local sheriff’s department. requested that he conduct a CVSA exam on a subject that they believed may have murdered his sister-in-law fourteen years ago in 1981. Over the years, the subject had taken 4 polygraphs from 3 different examiners, all of which had been inconclusive. The subject agreed to the CVSA exam and failed each of the 3 tests. After being shown the charts and informed of the results, the subject confessed to the murder. Following his confession, the subject took the detectives to the site where he buried his sister-in-law’s body, providing the only direct evidence of his crime.

New York, Madison County Sheriff’s Department  – Professor James Chapman, noted criminologist and CVSA examiner was summoned to the Sheriff’s Department to assist with the interview of an individual that had been the main suspect in a 1981 murder. He had taken a polygraph which was inconclusive and, without other leads, the case grew cold. The same suspect was again requested to take a polygraph in the same case ten years later in 1991. This time the suspect passed the polygraph and was dropped as a suspect. In 1996, the investigator in the case requested that the same suspect take a CVSA exam from Professor Chapman. After reviewing his CVSA charts, which clearly showed that he was the killer, the suspect made admissions and provided written statements regarding his participation in the murder.

West Virginia, Raleigh County Sheriff’s Office.  – 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. Eventually three suspects were named and D/Cpl. Bare conducted CVSA exams on each and cleared them of involvement. 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.

Florida, Cocoa P.D.  – Analyst/Det. Gordon Chase was assigned to review the ‘cold’ homicide cases at his department While reviewing the first case which involved the brutal murder of a young woman six years prior, Det. Chase noticed that both suspects had voluntarily taken and passed polygraph examinations and because of that, were no longer considered suspects. He also discovered that both had given sworn, tape recorded statements in which they had denied any involvement in the murder. Det. Chase analyzed the taped statements utilizing the CVSA and while he was able to clear one suspect, the other suspect displayed deception when she denied committing the murder. Det. Chase located the second suspect and requested that she come in for questioning. When she appeared for questioning, the suspect agreed to take a CVSA exam. The CVSA exam clearly indicated that she was the one that had killed the young woman six years earlier. After forty minutes of interrogation, the suspect admitted to the murder and also how she had disposed of the murder weapon.

Ohio, Fostoria P.D.  – Analyst/Det. Phil Kleman reports that as an analyst with another department, he was asked by the Fostoria P.D. to test an individual who was suspected of murder. The suspect had just taken a polygraph examination from an Ohio Bureau of Criminal Investigations polygraph examiner who reported the results of the polygraph examination to be inconclusive bordering on truthful. The subject denied any involvement in or knowledge of the murder and agreed to take the CVSA, just as he had agreed to take the polygraph. The CVSA showed very clearly that the subject had committed the murder and when confronted with his deceptive charts, gave a full confession. The Fostoria P.D. has now purchased their own CVSA and trained several detectives as examiners.

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.
