Savannah Guthrie has appealed for the release of her 84-year-old mother Nancy Guthrie, two weeks after she disappeared in a suspected kidnapping case, telling everyone involved that "it's never too late to do the right thing", the BBC reports today.
In her latest video address, the American TV presenter addresses "anyone who is holding her or knows where she is," adding that those closest to Nancy Guthrie "still have hope."
This comes as investigators are analyzing DNA found on a glove they recovered. The glove being tested appears to match the glove worn by the suspect who appeared in doorbell footage taken the night Nancy Guthrie disappeared.
Authorities believe the suspect in the video kidnapped Guthrie in the early morning hours of February 1st.
The US Federal Bureau of Investigation (FBI) announced on Sunday that investigators found the glove in a field next to the road, about two miles from Guthrie's home in Tucson, Arizona.
The agency collected about 16 gloves from various locations near her home, although it turned out that most had been discarded by residents searching for Guthrie.
"The one on which the DNA profile was found is different and appears to match the gloves of the person in the surveillance video," the FBI said.
The agency said it had received preliminary DNA test results from the glove and was still awaiting "quality control and official confirmation" before entering the "profile of the unknown male" into its database.
Earlier this week, investigators released video from a doorbell camera on the front door of Guthrie, showing a masked man wearing gloves and a backpack.
In the video, the suspect approaches the camera and attempts to cover it with his gloved hand, before grabbing bushes from the yard to block the camera.
After forensic analysis of the footage, the FBI said earlier this week that it believed the man was between 5'9" and 5'10" (175 and 177 centimeters) tall and of average build.
The FBI also drew attention to the backpack the suspect was carrying in the video, identifying it as a 25-liter "Ozark Trail Hiker Pack."
The clothing and face mask worn by the suspect in the video appear to have been purchased at Walmart, Pima County Sheriff Chris Nanos told CBS News, the BBC's US partner. CBS also reported that the backpack is sold exclusively at Walmart stores.
Officials reviewed surveillance footage from nearby Walmart locations, Nanos said, although a company representative declined to comment to CBS.
Police said the description of the suspect "remains a key focus," but added that "investigators are not ruling out any person or any possibility."
Guthrie was last seen on the evening of Jan. 31, when a family member dropped her off at home after a gathering at the home of her other daughter, Annie Guthrie.
Members of her church noticed her absence the next day and notified the family.
In the two weeks since Guthrie's disappearance, the FBI and the Pima County Sheriff's Office conducted an extensive search that involved helicopters, sniffer dogs and hundreds of police officers, while collecting thousands of tips by phone.
Officials have warned that her health could be seriously compromised without treatment. Nanos, the local sheriff, said she was "not in good physical health" but had no reported cognitive problems.
On Friday, authorities executed a search warrant at a home two miles from Nancy Guthrie's home, but no one was arrested.
Local officials also said that investigators found DNA at Nancy Guthrie's address that did not belong to her or anyone close to her.
The FBI has increased the reward for information about her disappearance from $50.000 to $100.000.
