A forensic expert suggests investigators conduct another round of DNA swabbing at Nancy Guthrie’s home, believing the suspect may have left saliva at the scene.
Renowned genetic genealogist CeCe Moore, who has helped solve over 300 cases using DNA, told NewsNation’s Natasha Zouves that she believes a re-swab of Nancy’s home could uncover additional DNA evidence.
“I would still go back and re-swab parts of that house and look for even like a rootless hair,” Moore explained. “We can solve these cases now with just a rootless hair.”
Nancy Guthrie Update: Forensic Expert Doubts Suspect Left No DNA Trace
Early on in the investigation, authorities found mixed and partial DNA at Nancy Guthrie’s home. Pima County Sheriff Chris Nanos revealed that there are “challenges” with the sample and that it could take up to a year to resolve, according to NBC News.
Weighing in, Moore said she finds it unlikely the suspect didn’t leave enough DNA behind to identify him, adding that he likely left saliva at the scene.
“We think he had that bite flashlight in his mouth, and I doubt he kept it in his mouth for the full 40 minutes or so that he was there,” the forensic expert explained. “So, as careful as he was to try not to leave his DNA, he would have taken that out of his mouth, and he would have immediately had his DNA all over the outside of that glove, and he had to have touched something.”
Genetic Genealogist CeCe Moore Suggests a Re-Swab
Moore suggests investigators conduct a re-swab of the Nancy Guthrie crime scene, even though more than 40 days have passed since her disappearance.
“We have been able to solve cases with really old DNA,” she added. “DNA is actually pretty hardy. And so, I believe if they haven’t collected his DNA, it is still at that crime scene somewhere, and they should revisit it even though it’s been open to the family.”
Moore emphasized that, despite the house being returned to the family, it shouldn’t hinder the identification of DNA.
“You can still rule out the people that have been there,” the expert continued. “So, that still shouldn’t be a roadblock to potentially identifying that unknown male perpetrator’s DNA.”
Nancy Guthrie was abducted from her Tucson, Arizona, home on February 1st. Authorities have not yet identified the suspect or her location.
If the kidnappers was in the house for a period of time they should check the bathroom really good for public hair’s or the sink for spit or anything else. They mostly used the restroom or went to the kitchen for a drink. I do believe that criminal’s are not the smartest people around, there is no way that anyone goes in to a place n doesn’t leave some kind of DNA behind.
What if she was mauled by a bear or another big animals ,maybe that’s why they can’t find her and maybe that’s why the abducter is also not found ,I’m guessing this because in one of the videos I did see bears around the desert ,anything is possible ,I think ,????????????
