The search for Nancy Guthrie, the 84-year-old mother of NBC’s “Today” show co-anchor Savannah Guthrie, entered its 10th day on Feb. 10, when authorities detained an individual for questioning in connection with her abduction.

The Pima County Sheriff’s Department, with assistance from the FBI, detained the individual at a location south of Tucson, a law enforcement official briefed on the investigation told ABC News, adding that investigators are preparing to search a location associated with the individual.

The news came after FBI Director Kash Patel released surveillance video Feb. 10 showing a masked, armed person on Guthrie’s porch the night she went missing. Patel said the images were recovered from backend system data. He posted the images and video directly on X, emphasizing the recovery process and describing the individual as armed and involved in tampering.

The footage shows the individual wearing long sleeves, pants, gloves, a backpack, and attempting to obscure or tamper with the camera — initially trying to cover it with a hand/glove, then grabbing plants from the yard to place in front of it.

The FBI said in a statement Feb. 9 it is “not aware of any continued communication between the Guthrie family and suspected kidnappers,” nor has it identified a suspect or person of interest in the case. More FBI personnel have been deployed to Tucson, Arizona, to assist the Pima County Sheriff’s Office, which is leading the investigation.

President Donald Trump offered the full support of federal law enforcement to the Guthrie family last week, as Zeale News previously reported. After the release of the surveillance video, White House Press Secretary Karoline Leavitt said Feb. 10 that she and the President have reviewed the footage and encouraged anyone with information about the case to contact the FBI.

The same day, the White House also reposted the surveillance footage on its X account and emphasized spiritual support for the Guthries as well. 

“The prayers of the entire White House are with the Guthrie family,” the White House account stated.

Savannah Guthrie posted a video appeal on social media Feb. 9, describing the ordeal as “another week of this nightmare” and pleading for the public’s help.

“We believe our mom is still out there,” she said. “We are at an hour of desperation, and we need your help.”

The latest purported ransom note, sent to local media outlets including KGUN in Tucson, demanded $6 million in Bitcoin by 5 p.m. local time on Feb. 9 and included threats to Guthrie’s life if unmet, according to the Arizona Daily Star. Authorities have not confirmed the note’s authenticity or whether any payment was made as of Feb. 10. Previous alleged deadlines days prior also passed without reported contact or proof of life. 

Nancy Guthrie was last seen Jan. 31 when family members dropped her off at her home in the Catalina Foothills area near Tucson after dinner, according to Arizona Family. She was reported missing Feb. 1 after failing to appear at church, according to the Arizona Daily Star. Investigators believe she was taken against her will, citing signs of forced entry, blood droplets confirmed by DNA to be hers, a removed Ring security camera, and her phone and Apple Watch left behind, according to KGUN, a local ABC affiliate. 

Authorities continue to follow new leads and have expanded searches, including collecting DNA samples from service workers who visited the home, FOX News reported. A $50,000 reward remains for information leading to her recovery.

The Pima County Sheriff’s Office and FBI urged anyone with information to contact investigators. No updates on Guthrie’s condition or location have been released.
