Nancy Guthrie, 84, was kidnapped on Sunday, Feb. 1.
The search is ongoing for 84-year-old Nancy Guthrie, the mother of "Today" show host Savannah Guthrie, who investigators say appears to have been kidnapped from her Tucson, Arizona, home in the early hours of Sunday, Feb. 1.
The FBI has released photos and videos of an armed person in a mask in front of her home, appearing to tamper with a security camera.
Anyone with information is urged to call 911 or the Pima County Sheriff's Department at 520-351-4900.

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.

President Donald Trump said in an exclusive phone interview with the New York Post that Nancy Guthrie must be released safely, or the kidnappers could face the death penalty if she is found dead.
Trump said Nancy Guthrie's kidnappers will face "very, very severe -- the most severe" consequences when caught.
According to the Post, the reporter pressed Trump about whether that meant the Department of Justice would request the death penalty. Trump responded, "The most, yeah -- that’s true."
The interview came after Trump posted about the case on social media, saying that he hopes "there will be a positive result."
White House press secretary Karoline Leavitt said during a briefing last week that the administration wants the kidnappers to be "held to the fullest extent of the law possible."
