Tucson, Arizona - A former FBI agent has offered up a dark take in the case of Nancy Guthrie's disappearance regarding the apparent lack of a legitimate ransom note, and it relates to the blood found at the 84-year-old's home.

As authorities continue to examine evidence and search for a lead in the case of Today show host Savannah Guthrie's mom going missing, a former agent is sharing a possibility that some following the case have speculated about on social media, as well.

“With blood on the porch of Nancy’s house, I think you have to put into play the very strong possibility that Nancy didn’t survive long enough for them to even get a ransom note," former agent Steve Moore recently told NewsNation reporter Brian Entin.

Law enforcement officers confirmed soon after Nancy's Feb. 1 disappearance that the blood they found near the front door of her Arizona home belonged to her.

There has been much debate regarding the legitimacy of the ransom notes received thus far. After Reuters reported that an anonymous source claimed that investigators had determined that all the ransom notes were fake, the FBI's Phoenix office revealed on July 1 that while "some [notes] have been deemed to be extortion attempts without legitimacy," not all have been ruled out.

The intelligence agency has yet to provide another public update in the case, but authorities continue to investigate the case as a kidnapping.

Some started speculating that Savannah's multi-day absence from the Today show last week was in relation to her mother's disappearance, but People reported the TV host had several days off and is expected to return this coming week.
