DNA evidence not belonging to Nancy Guthrie or her “close contacts” was found at her home, police say.

“DNA other than Nancy Guthrie’s and those in close contact to her has been collected from the property,” the Pima County Sheriff’s Department (PSCD) said in a statement to PEOPLE on Friday, Feb. 13. “Investigators are working to identify who it belongs to. We are not disclosing where that DNA was located.”

Police also said that “several gloves” have been found during their investigation, with the closest gloves being found approximately two miles from the home.

“Reports that a glove was found inside the residence or on the property are inaccurate. All collected evidence has been submitted for laboratory analysis,” the PCSD added, before noting that “investigators are not ruling out any individuals or possibilities.”

The 84-year-old mother of Today show co-host Savannah Guthrie was last seen at her Tucson, Ariz., home on the night of Jan. 31. Her family reported her missing around noon on Feb. 1.

Pima County Sheriff Chris Nanos previously said blood was discovered on the exterior porch of Nancy’s home that matches her DNA, though her whereabouts remain unknown. The Pima County Sheriff’s Department has also said that gloves and other pieces of evidence tied to the case are undergoing forensic analysis.

Amid the investigation, ransom notes tied to Nancy’s disappearance were allegedly sent to several media outlets. The FBI has said those are being investigated and that they are not aware of any communication between the alleged kidnapper(s) and the Guthrie family.

The FBI has since released surveillance footage of a masked and “armed” person appearing to tamper with a Nest camera at Nancy’s front door on the morning of her kidnapping.

The FBI’s Phoenix office described the suspect as a “male, approximately 5’9” – 5’10” tall, with an average build. In the video, he is wearing a black, 25-liter ‘Ozark Trail Hiker Pack’ backpack,” per a post on X shared Feb. 12.

Sharing photos and videos of the suspect in an Instagram post, Savannah urged her followers to help identify the person, writing that someone may recognize them. “We believe she is still out there. Bring her home,” she wrote.
