FBI testing has found no match for the DNA taken from a glove discovered near Nancy Guthrie's Arizona home, and authorities say they may now turn to genetic genealogy to try to identify who left it.
Investigators say the glove was located about two miles from the 84‑year‑old's house in the Catalina Foothills and appears similar to one worn by a person seen in security video near the property.
Forensic work produced a full DNA profile believed to belong to an unknown man, but when the sample was entered into the FBI's Combined DNA Index System, or CODIS, it did not match any existing profiles. Officials have also said the DNA on the glove does not match samples collected inside Guthrie's home, according to Parade.
With traditional database searches exhausted, investigators are weighing the use of investigative genetic genealogy, a method that compares an unknown profile with DNA submitted to consumer testing companies to identify possible relatives.
If approved, specialists could build out family trees from partial matches and then work with public records to narrow potential suspects, a technique that has helped solve several high‑profile cold cases in recent years. Authorities stress that any such work would follow company policies and legal guidelines for law enforcement access to genealogy data.

The DNA development comes as the search for Guthrie, the mother of "Today" co‑anchor Savannah Guthrie, stretches into a third week with no confirmed sightings, NBC News reported.
She was reported missing on February 1, after she failed to appear for an online church service and family members found her house empty. A relative had last seen her the night before, when she was dropped off at home following a dinner.
Investigators later discovered that her doorbell camera was missing and that her cellphone and pacemaker stopped transmitting data in the early‑morning hours, suggesting she was taken from the home overnight.
Small blood stains on the front porch were matched to Guthrie, and the Pima County Sheriff's Department has described the case as a suspected abduction but has not named any suspects or announced arrests, as per Fox10 Phoenix.
