Casey Anthony's parents took polygraph test to 'clear their name,' expert says

 The results of polygraph tests given to Casey Anthony's parents are revealed in a new TV special that aired Thursday.

George Anthony, 72, and Cindy Anthony, 65, passed polygraph tests as part of A&E's new TV special, "Casey Anthony's Parents: The Lie Detector Test," in which they were asked a series of questions regarding the murder of their granddaughter Kelly Anthony and their Were asked. Daughter Casey Anthony accused her father of molestation.

Casey Anthony, 37, known as "America's Most Hated Mom", was accused of murdering her 2-year-old daughter Kelly in 2008, but has alleged that her father is the real culprit.

In the new TV special, George and Cindy take a polygraph test to prove their innocence on charges of murdering their granddaughter and sexually assaulting Casey.

But the tests, though successful, also evoked some intense emotions in both parents.

Lisa Ribakoff, a New York-based private investigator and polygraph expert, said, "My opinion about taking the test was to clear their names, not only as suspects despite the closed investigation, but to validate the stories they had been telling for years. Telling from." , told Fox News Digital. "The allegations were made by Casey and he wanted to use the polygraph as an investigative tool to help give credibility to his statements."

Ribakoff said the polygraph exam measures a person's heart rate, blood pressure, respiration and more, so having cameras in the same room as the parent taking the test could affect the results.

“There are a lot of stumbling blocks,” he said. “This is an emotional topic and a difficult issue to discuss. I encounter such examinees all the time. This is a normal reaction. It depends on the examiner. That he discusses things with them thoroughly to make sure they understand the questions, as well."

Ribakoff also said that the special "was edited, and the trailers were released to make George look guilty, which may be why viewers were so impressed."

At one point in the special, George accuses his wife of being controlling when she asks the production crew to move the couch they are sitting on. Cindy becomes emotional and hints at the seriousness of the polygraph tests, saying that if George "blews it all" he "might have to go to jail".

"Since June 16, 2008, Kelly has been my No. 1 priority as far as finding out what happened to her and getting her back," Cindy says in the special. "I lost Casey and my granddaughter that day, but Kelly was the priority. Kelly has always been my priority. My goal this whole time has been to find out the truth. And sitting here listening to (Casey) make up different stories." Live as it fits..."
