Nancy Guthrie live updates: Suspect's clothing may have been purchased at Walmart; family cleared

Pima County Sheriff Chris Nanos said Monday that members of the Guthrie family are "cleared" as suspects in Nancy Guthrie's disappearance.

"To be clear ... the Guthrie family -- to include all siblings and spouses -- has been cleared as possible suspects in this case," the sheriff said in a statement. "The family has been nothing but cooperative and gracious and are victims in this case."

"The Guthrie family are victims plain and simple," the statement said.

ABC News previously reported that, according to law enforcement sources, investigators were leaning away from the Guthries as suspects.

The Pima County Sheriff's Department said it's possible the suspect in Nancy Guthrie's kidnapping may have purchased the clothes he's seen wearing on the surveillance camera at Walmart, but that clothing is not exclusively available at Walmart.

Investigators last week were working to trace the point of sale of the suspect's backpack, which was sold at Walmart.

Meanwhile, the FBI is focused on the unknown male DNA from a glove found about 2 miles from Nancy Guthrie's home.

The FBI said it received preliminary results on Saturday. The FBI said on Sunday it was "awaiting quality control and official confirmation" before putting unknown male profile into the Combined DNA Index System, the national database known as CODIS.

The glove with the DNA profile "appears to match the gloves of the subject in the surveillance video," the FBI said.

"Today" show host Savannah Guthrie shared a video on social media on Sunday, as the search continues for her 84-year-old mother, Nancy Guthrie, who was taken from her Arizona home two weeks ago on Feb. 1.

Speaking directly to "whoever has her or knows where she is," Savannah Guthrie said, "It's never too late, and you're not lost or alone, and it is never too late to do the right thing, and we are here."

"We still have hope, and we still believe," Savannah Guthrie said. "We believe in the essential goodness of every human being, and it's never too late."

Investigators lifted DNA of an unknown male profile from a glove found along roadside brush about two miles from Nancy Guthrie's home, sources briefed on the investigation told ABC News.

The development was also confirmed by the FBI.

The glove appears to generically match the kind of gloves worn by the suspect who was recorded on the missing 84-year-old Guthrie's doorbell camera, sources said.

Pima County Sheriff Chris Nanos told ABC News on Friday that DNA had been retrieved from multiple gloves.

"We've gotten DNA back," Nanos said. "So that's of use. Now [we] have to go through and try to eliminate people or make people."

The sheriff's department sent the gloves to a private lab for analysis in Florida on Thursday evening and they arrived at the laboratory on Friday, according to the FBI.

The FBI received preliminary results from the laboratory on Saturday and was awaiting quality control and official confirmation on Sunday before putting the unknown male profile into a national database unique to the bureau, known as the Combined DNA Index System (CODIS), the FBI said. This process typically takes 24 hours from when the bureau receives DNA, according to the FBI.

Investigators collected approximately 16 gloves in various areas near Nancy Guthrie's house, sources told ABC News. Most of the gloves were searchers' gloves that were discarded in various areas when they combed the area, according to the FBI.

The one glove with the DNA profile recovered is different from other gloves found in the area and appears to match the gloves of the subject in the surveillance video, the FBI said.
