Sheriff: No Matches for DNA on Glove in Guthrie Case

Investigators had hoped a discarded glove would crack the Nancy Guthrie case. It didn't. Pima County Sheriff Chris Nanos said Tuesday that DNA taken from a glove found about two miles from the 84-year-old's Arizona home produced no match in the FBI's national database, the Guardian reports. The glove resembled one seen on security footage worn by Guthrie's abductor, and tests detected an unknown man's DNA. But the sample doesn't match anything in federal records or any DNA collected from inside Guthrie's residence, Nanos said.

"There were no DNA hits in CODIS" and "there have been no confirmed CODIS matches in this investigation," the sheriff's department said, per the AP, referring to the Combined DNA Index System, which holds DNA from suspects and convicted criminals, along with evidence from the scenes of unsolved crimes. "Now we start with genealogy and some of the partial DNA we have at the home," Nanos tells NBC News. "To me, that's more critical than any glove I found 2 miles away. I'm not dismissing the glove 2 miles away, but I have gloves 5 miles away, 10 miles away, so we prioritize."

With the case now in its third week, authorities are expected to submit the profile to a commercial genealogy database in hopes of tracing relatives of the unknown man and building out a lead that way. On Sunday, Guthrie's daughter, Today show co-anchor Savannah Guthrie, issued a new public appeal on Instagram to whoever is responsible, saying "it is never too late to do the right thing."
