New images released by the United States Federal Bureau of Intelligence (FBI) show a person in a full-face balaclava apparently tampering with a front door camera outside the home of the mother of a US TV host who has been missing for ten days.
The six still photographs and three videos posted by FBI director Kash Patel on his X account show a masked person on a deserted doorstep in the dark, in eerie black and white imagery.
Nancy Guthrie, mother of NBC News Today co-host Savannah Guthrie, is believed to have been kidnapped from her home in Tucson, Arizona, on the night of 31 January or in the early hours of 1 February, sparking a massive hunt in a case that has gripped the US.
"The video was recovered from residual data located in backend systems," Patel wrote, saying the images show "an armed individual appearing to have tampered with the camera at Nancy Guthrie's front door the morning of her disappearance".
Authorities have not identified any suspects or persons of interest.
Investigators had been hopeful that cameras at the home would turn up some evidence about how she went missing but the doorbell camera was disconnected early on Sunday.
And while software data recorded movement at the home minutes later, Nancy Guthrie did not have an active subscription so none of the footage could be recovered, Pima County sheriff Chris Nanos had said.
White House spokesperson Karoline Leavitt began a media briefing by saying she and President Donald Trump had just reviewed the newly released imagery.
"The president encourages any American across the country with any knowledge of the suspect to please call the FBI," she said.
