In a major development in the Nancy Guthrie investigation, the missing woman’s family members have reportedly undergone polygraph tests and passed them. Those tested include Nancy’s daughter, Savannah Guthrie, son Camron Guthrie, daughter Annie Guthrie, and son-in-law, Tomasso Cioni.
The polygraph test measures a person’s physiological responses, such as heart rate, blood pressure, respiration, and skin conductivity, to check whether they are lying or telling the truth. Reports that Nancy Guthrie's family passed the test first surfaced when former SWAT team leader Chad Ayers spoke about it on The Megyn Kelly Show.
Ayers Says Nancy Guthrie’s Family Has Passed Polygraph Tests
Reports say Nancy Guthrie’s family passed polygraph tests, clearing them of suspicion.
During an appearance on the podcast on March 16, Ayers said, “It has been confirmed this morning—and I'm sure we all assume this—that every family member passed polygraphs with flying colors.” The test is particularly significant because some people have repeatedly raised doubts about Annie Guthrie and Tomasso Cioni's involvement in Nancy Guthrie's disappearance.
Despite the Pima County Sheriff Chris Nanos maintaining that family members are cleared of suspicion, some independent journalists have continued to question Cioni, as he was reportedly the last person to see Nancy Guthrie before her disappearance.
The speculation began at the beginning of February when journalist Ashleigh Banfield claimed that Cioni was considered the prime suspect in the investigation. Other independent investigators, including Jonathan Lee Riches, later joined in and echoed similar claims. However, the speculations were not backed by evidence.
Nanos eventually released a statement to refute the claims and said, “The family has been nothing but cooperative and gracious and are victims in this case. To suggest otherwise is not only wrong, it is cruel. The Guthrie family are victims plain and simple.”
However, Banfield was not convinced and again raised questions about Cioni's involvement in Nancy Guthrie's kidnapping. Recently, Megyn Kelly came up with the information that Savannah was furious with her brother-in-law’s name being unnecessarily dragged into the case by Banfield.
“I have not been able to confirm that the Guthrie family wants to sue Ashleigh Banfield, but I have confirmed that Savannah is livid about that report and definitely does not suspect her sister or her brother-in-law. Can you blame her? I mean, of course, she loves her sister, I'm sure she loves her brother-in-law, and I'm sure she genuinely doesn't believe they had anything to do with it,” Kelly said.
Speculation About Tomasso Cioni Is Put to Rest
Tommaso Cioni has been a focus of suspicion for many independent journalists.
Now that the polygraph test once again seems to have cleared Cioni’s name, Kelly said people can finally move on from the narrative that Annie Guthrie or her husband was in any way involved in the crime.
“That information is huge. So then that means—I don't know, some people don't believe in the polygraphs, I do—but if that's true, then we can move on from the brother-in-law and the sister,” the podcast host added.
However, Ayers also shared a disappointing update about the case during the show, saying that sources told him investigators still have no concrete leads. “I can report from a very, very reliable source that is boots on the ground there that the FBI and the Pima County Sheriff's Office have no leads. No solid suspects,” Ayers said.
