Federal authorities have released new images and video in the widening search for Nancy Guthrie, the 84-year-old mother of television host Savannah Guthrie, who disappeared from her Tucson, Arizona, home in late January.
Investigators say the material shows a masked and armed individual tampering with a doorbell camera during the early hours of the morning when Guthrie is believed to have been taken against her will.
The case has drawn national attention as officials continue to pursue leads, review ransom communications, and appeal for public assistance.
The FBI and the Pima County Sheriff's Department said the images were recovered after efforts to restore surveillance footage that may have been lost or damaged.
The footage, recorded around 3 a.m. on February 1, shows a person wearing a face mask, gloves, a backpack, and what appears to be a gun holster approaching the front door and attempting to block the camera with nearby vegetation.
Authorities believe the individual was aware of the camera’s location and disabled it shortly afterward.
FBI Director Kash Patel said, "Law enforcement has uncovered these previously inaccessible new images showing an armed individual appearing to have tampered with the camera at Nancy Guthrie's front door the morning of her disappearance."
Investigators have also confirmed that blood found on the porch belonged to Guthrie and that her pacemaker disconnected from her phone in the pre-dawn hours of the same day.
Officials say at least two ransom notes were initially sent to media outlets, with one arrest made in connection to a hoax message, while other communications remain under investigation.
Savannah Guthrie and her siblings have repeatedly appealed to the public for information, sharing the newly released images on social media.
In one post accompanying the footage, she wrote, "We believe she is still alive. Bring her home."
The FBI is offering a $50,000 reward for information leading to a breakthrough in the case.
White House Press Secretary Karoline Leavitt said President Donald Trump reviewed the images and urged anyone with relevant knowledge to contact authorities.
Law enforcement officials continue to say there are no identified suspects or vehicles, as the search enters its second week.
