Investigators have found DNA at the home of Nancy Guthrie, the missing mother of US news anchor Savannah Guthrie, which does not belong to her or those in close contact to her, local officials said. The Pima County Sheriff's Department is working to identify the source of the DNA, but has not disclosed where it was located. Additionally, several gloves were found approximately two miles from Nancy Guthrie's home.

The 84-year-old disappeared in the middle of the night from her residence in Tucson, Arizona, nearly two weeks ago. Authorities believe she was taken against her will. The sheriff's department stated that reports of a glove found inside her home are inaccurate. All collected evidence has been sent for laboratory analysis.

On Thursday, the FBI released a physical description of a suspect, describing him as a male between 5ft 9in and 5ft 10in tall with an average build. They established identifying details about the suspect after analyzing footage from a doorbell camera outside Guthrie's home. The suspect was seen wearing a 25-litre Ozark Trail Hiker Pack backpack in the footage.

Since the release of the doorbell footage, investigators have received over 13,000 tips, including 4,000 in just 24 hours. The FBI has increased the reward for information about Guthrie's disappearance from $50,000 to $100,000. While the description of the suspect remains a key focus, investigators are not ruling out any individuals or possibilities.

Authorities have also appealed for video footage from neighbors, stressing that Nancy Guthrie requires daily medication and has limited mobility. Savannah Guthrie and her siblings have made public pleas directed at their mother's abductor, expressing their belief that she is still alive and offering to pay for her safe return.
