And what is Guthrie's family saying?

They're continuing their calls for help from the public.

The FBI has yet to say whether it's verified the authenticity of any supposed ransom notes, but it did say it's taking seriously some ransom messages that were sent to several media outlets.

Meanwhile, Nancy Guthrie's children have made several appeals to whomever might have their mother, and they said they're willing to pay ransom.

Here's Savannah Guthrie in an Instagram plea over the weekend directly to the alleged ransomers.

On Monday, the FBI said it wasn't aware of any, quote, continued communication between the Guthrie family and suspected kidnappers.

After the FBI released the surveillance footage, Savannah Guthrie posted the video to her Instagram page and said that she believes her mother is still alive.

The video appears to show a masked armed subject wearing gloves and carrying a backpack.

Officials have said that on the morning of her disappearance, Guthrie's doorbell camera disconnected at 1.47 a.m.

Motion had been detected on the camera.

But until today, officials had not released any of the footage to the public.

The search to find Guthrie, who is 84, has become more frantic in its second week.

The FBI has said that it has a ransom note from the people who say they took her.

Guthrie's children have said they are willing to cooperate, including paying her captors.

They say they still believe their mother is alive.
