TUCSON, Ariz. — Videos of what authorities are calling a "subject" in the Nancy Guthrie investigation have been released by the FBI.
"The video was recovered from residual data located in backend systems. Working with our partners - as of this morning, 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."
Minutes after the photos were posted, NBC law enforcement and national intelligence reporter Tom Winter reported that the Guthrie family does not recognize the person in the image. He also said the individual has an apparent gun in his or her waistband.
NBC's "Today" anchor Savannah Guthrie, Nancy's daughter, also shared the images on her Instagram account.
"We believe she is still alive," she said. "Bring her home."
About a half hour after the first video was released, the FBI posted a second video to its X account.
That video, three seconds long, shows the same person walking towards the door, but turning their face leftward away from the camera.
The Pima County Sheriff's Department echoed Patel's message in an X post of their own.
Guthrie, 84, is the daughter of NBC's "Today" anchor Savannah Guthrie. She has been missing since Sunday, Feb. 1.
So far, no suspects have been named in the case.
