The DNA profile was recovered from gloves found during the investigation into the disappearance of Nancy Guthrie in Arizona.

Additional DNA evidence found at Guthrie's residence still was being analyzed, sheriff's spokesperson Angelica Carrillo said in a Feb. 17 update.

Nancy Guthrie is believed to have been taken against her will from her Tucson, Ariz., home in the early morning hours of Feb. 1.

Investigators in the Nancy Guthrie case have turned to genetic genealogy as they try to make the most of potential DNA evidence.

Investigators in the Nancy Guthrie disappearance say DNA from gloves did not match any entries in a national database.

Authorities trying to solve the disappearance of Nancy Guthrie say they might tap DNA genealogy databases, the same step that police took to unravel a decades-old series of murders in California and the fatal stabbings of four college students in Idaho.

DNA from gloves found two miles from Nancy Guthrie's home doesn't match DNA in the FBI database. Investigators explore genetic genealogy as search continues.

Only a few years ago, Tuesday’s announcement that a glove believed to be connected to the disappearance of Nancy Guthrie in Tucson, Arizona, had no match to a DNA database would have been a dead end.

Nancy Guthrie, mother of "Today" host Savannah Guthrie, has been missing for 20 days from her Tucson-area home. Investigators have recovered doorbell footage and DNA evidence and are searching for her pacemaker.
