TUCSON, Ariz.
Investigators detained a person for questioning Tuesday in the disappearance of Nancy Guthrie, marking a potential break in a case that has captivated the nation for more than a week.
The Pima County Sheriff’s Department said deputies took the person into custody during a traffic stop south of Tucson.
Officials did not immediately confirm if the individual is the same masked person seen in surveillance footage released hours earlier by the FBI.
That footage, taken the night Guthrie vanished, shows a figure in a ski mask and backpack approaching her front door.

The person, who has a handgun holster visible, appears to be deliberately avoiding the doorbell camera—tilting their head down, trying to cover the lens with a gloved hand and a piece of a plant torn from the yard.
The FBI, which released the video, referred all questions about the detention to the sheriff’s department.
Nancy Guthrie, 84, is the mother of “Today” show co-host Savannah Guthrie. Her disappearance has prompted a massive search and public appeals, including a video statement from Savannah Guthrie directed at potential kidnappers over the weekend.
