PIMA COUNTY, Ariz. -- The search for 84-year-old Nancy Guthrie, the mother of "Today" host Savannah Guthrie, began after she was abducted from her home near Tucson, Arizona, on Sunday, Feb. 1, authorities said.
The Guthrie family has made multiple public pleas for any information surrounding their missing mother.
On Feb. 10, the FBI released an updated missing person poster that includes images of a potential subject from newly released doorbell camera video.
Anyone with information is urged to call 911 or the Pima County Sheriff's Department at 520-351-4900.
Investigators believe Nancy Guthrie was abducted in her sleep early on Feb. 1, according to the sheriff's department.

DNA from the glove recovered near Nancy Guthrie's home remains at a private lab in Florida, where the Pima County Sheriff's Department sent it on Feb. 12, law enforcement sources told ABC News.
The sample is still undergoing quality control tests before the FBI hopes to run it through CoDIS in the "near future," the sources said.

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."
