Nancy Guthrie update: DNA couldn't be profiled from crime scene hair sample, sheriff says
Pima County Sheriff Chris Nanos says investigators are working with the FBI and multiple crime labs to analyze evidence
{{#rendered}} {{/rendered}}TUCSON, Ariz. — Investigators couldn't obtain a DNA profile from a hair sample recovered from within Nancy Guthrie’s home, Pima County Sheriff Chris Nanos told Fox News Digital in a new interview Thursday, as the case nears the six-month mark.
"Yes, there was a hair. We had it and thought, 'Okay, well, we'll do the DNA first,' right? You're going to do DNA before something else," he explained.
Working with the FBI, investigators sent the sample to a California laboratory for additional DNA testing.

"It came back...there's no DNA," Nanos said. "But does that mean the hair isn't that of the suspect? We won't know that till we have the suspect's hair. You don't just destroy it."
Investigators have preserved the sample and it still may be of use later, he added.

"There's other things that hair may prove valuable for, but right now it was just about, 'Is there any DNA there?' And the answer was no," the sheriff said. "That was just a matter of weeks ago."
Guthrie is the 84-year-old mother of "Today" co-host Savannah Guthrie. She will have been missing for six months on Saturday.

DNA testing remains a priority in the case, and Nanos said investigators continue working with multiple crime labs to analyze evidence collected from the scene.
