Law Enforcement Embracing Improved Accuracy and Efficiency of New Crime Fighting Technologies
DNA and Computer Voice Stress Analysis Help Clear the Innocent, Find the Guilty

LEWES, Del., Nov. 6, 2018 /PRNewswire/ — Innocent people are being exonerated in record numbers as new technologies such as DNA become more sophisticated and the Computer Voice Stress Analyzer (CVSA) is increasingly being used for truth verification instead of the old polygraph.  This is according to Clifford Payne, an Investigator with the Atlanta (GA) Police Department who also serves as a Regional Director of the National Association of Computer Voice Stress Analysts, an organization representing the nearly 2,000 US law enforcement agencies that utilize the CVSA.

“As law enforcement professionals, our main goal is to make sure only the guilty are prosecuted,” stated Payne.  “With the refinement of DNA testing we are now better able to accurately determine where the criminal justice system failed in the past as innocent men and women, some whose lives are ruined forever, are being released from prison on a regular basis.  This is in no small part due to organizations such as the Innocence Project, improved DNA testing, and the help of technologies such as the CVSA.”

Miami-Dade (FL) Police Det. Lisa Morales is among the thousands of detectives that have experienced this first hand.  Det./CVSA Analyst Lisa Morales reported that a female subject was accused of repeatedly stabbing her ex-boyfriend and children’s father. There was an adult male witness that implicated the female and uniformed officers were poised to arrest her based on both men’s statements even though the female insisted that she was being “framed” by the two men. The investigating detective just had one of those feelings and asked if Det. Morales would run a CVSA exam on the female. She passed and the “witness” ultimately confessed that he stabbed his uncle and they conspired to have the female falsely arrested so that the father could get custody of the children because the female refused to reconcile with him.  According to the NACVSA, this is just another example of the CVSA exam being used to clear someone rather than implicate them.  (Read more Real Cases.)

Payne stated that before the CVSA, law enforcement had to rely on the old polygraph.  “Our main problem was that 30% of polygraph examinations are ‘inconclusive’, meaning that there were no discernible results.  With the CVSA, there are always correct results 100% of the time.  When you also take in to account that it takes eight weeks to train a polygraph examiner and only five days to train a CVSA examiner, plus the fact that polygraph exams take between 2-3 hours and the CVSA exam can be performed in 1 hour with perfect results, it is clear which system to use.”  The Atlanta Police Department discontinued the polygraph in 2003 in favor of the CVSA.

Major US law enforcement agencies such as those in Atlanta, New Orleans, Nashville, Baltimore, and Miami, as well as the California Highway Patrol, depend upon the CVSA to investigate criminal cases as well as for screening police applicants.  “As an investigative and decision support tool the CVSA has proven itself to be invaluable to law enforcement,” stated Lt. Kenneth Merchant, of the Erie, PA Police Department, who serves as the Legislative Affairs Director for the NACVSA.

NITV Federal Services (NFS) is pleased to welcome Detective Jerry Crotty as its Director of Law Enforcement Operations. Jerry will oversee all aspects of law enforcement operations for NFS and provide direct advice and assistance to law enforcement agencies worldwide, as well as oversee our Technical Services Division.

Jerry joins the NSF team from the Manatee County Sheriff’s Office in Florida where he served for 20 years in various positions, including supervisory positions in such specialized disciplines as Crimes Against Children, Domestic Violence and Internet Crimes Against Children (ICAC).  While assigned to the State and Federal ICAC Task Force, Jerry developed ground-breaking techniques for using the CVSA® to identify and bring to justice serial child predators, which are now taught nationally.  These techniques were so significant and effective that in 2015 he received the National Association of Computer Voice Stress Analysts (NACVSA) annual Professor James L. Chapman Award for Excellence.  Jerry is considered an expert in interviewing and interrogation and has a confession rate well above 95%.  He is also an expert utilizing the CVSA and is highly experienced in conducting specialized covert and structured examinations.  Jerry holds a Master’s Degree in Science from the University of Central Florida.

Charles Humble, Founder of NITV Federal Services and the developer of the CVSA, states “We are very excited to have an individual with the qualifications and strong moral character of Jerry Crotty joining our team.  With his law enforcement background, especially in the ICAC arena, Jerry will bring a new dimension to an organization that is already recognized as the Gold Standard for our industry.”

CVSA Featured on National Television Show

The CVSA was recently featured on the daily television show “Crime Watch Daily”.  The episode featuring the CVSA aired on 12 May 2016, and told the story of the gruesome murder of Tim Johnson of Eaton, Ohio, who was murdered by his stepsister and her boyfriend.  The case was investigated by the Preble County Sherriff’s Office. Investigators credit the CVSA for providing crucial information that helped solve the case, stating that if it had not been for the CVSA the suspects would have “gotten away with murder.”  To view the Crime Watch Daily episode featuring the CVSA click here.

Fifth Annual (2016) Professor James L. Chapman Award for Excellence

The fifth annual (2016) Professor James L. Chapman Award for Excellence was presented to Investigator Mike DeFrancisco of the Columbus Division of Fire, Fire and Explosive Investigations Unit (OH) during the 2017 AEC. Mike Defrancisco has contributed immensely to the CVSA community by applying the CVSA to arson and explosive cases, which have less than a 5% solve rate nationwide.  Through strategic use of the CVSA in his investigations, Mike has helped his unit exceed a 20% clearance rate for such investigations, which is four time greater than the national average.  In addition Mike has served as a board member and the Director for Region 1 of the National Association of Computer Voice Stress Analysts (NACVSA) since its inception, and has contributed immensely to the professionalization of the NACVSA.  Our congratulations are offered to Investigator Mike DeFrancisco, his unit, and agency for a job well done!

  • Details of the 2017 Advanced Examiner Professional Development & Continuing Education Conference have been announced.
  • The fourth annual Professor James L. Chapman Award for Excellence was presented to Detective Jerry Crotty of the Manatee County (FL) Sheriff’s Office during the 2016 AEC. Detective Crotty is a member of the federally-funded Internet Crimes Against Children (ICAC) Task Force for Central Florida, and he developed innovative techniques for using the CVSA to conduct truth verification examinations of suspected sexual abusers of children arrested by the Central Florida ICAC Task Force.  Of major significance is the confession rate by the arrestees for unknown past sexual crimes against children, which went from zero (0%) to over 90% once the CVSA was employed as part of the investigative strategy.  The subsequent conviction rate for these offenders has been an astounding 100%! Our congratulations are offered to Det. Crotty, his agency and the ICAC Task Force for a job well done!
