A resident of Nancy Guthrie's neighborhood said the streets get 'pitch black' at night, making it hard for cameras to have captured video of suspects.
Savannah Guthrie has released a fourth video addressing the apparent abduction of her 84-year-old mother, Nancy Guthrie.
In a video posted Feb. 9 on Instagram, the "Today" anchor said she wanted to share "a few thoughts as we enter into another week of this nightmare."
"We believe our mom is still out there," she said. "We need your help. Law enforcement is working tirelessly, around the clock trying to bring her home, trying to find her. She was taken, and we don't know where, and we need your help."
Guthrie asked followers, even though those who do not live in Tucson, to contact law enforcement "if you see anything, if you hear anything, if there's anything at all that seems strange to you," adding, "We are at an hour of desperation, and we need your help."
She also thanked supporters for their prayers, saying she and her family "believe that, somehow, someway," that their mom "is feeling these prayers, and that God is lifting her even in this moment and in this darkest place."
Nancy Guthrie was reported missing from her home outside of Tucson, Arizona, on Sunday, Feb. 1, and has not been seen since the previous evening. Authorities in Arizona have said they believe Guthrie was taken from her home against her will, but no suspects or persons of interest have been identified.
Several media outlets have received purported ransom notes apparently connected to Guthrie's disappearance. On Feb. 5, the FBI said it was investigating a note that included two deadlines: one on Feb. 5 and another on Feb. 9. Authorities also confirmed on Feb. 6 that they were investigating a "new message regarding Nancy Guthrie."
The Guthrie family has so far released three videos on social media in which they addressed their mother's alleged kidnapper. In the first video, posted on Feb. 4, Savannah Guthrie and her siblings said they were "ready to talk" with the person behind the ransom notes.
"However, we live in a world where voices and images are easily manipulated," Savannah Guthrie said. "We need to know without a doubt that she's alive and that you have her. We want to hear from you and we are ready to listen. Please reach out to us."
A second video, posted on Feb. 5, featured only Savannah's brother Camron Guthrie, who said the family was still "waiting for contact" from their mother's kidnapper.
"Whoever is out there holding our mother, we want to hear from you," he said in the short message. "We haven't heard anything directly. We need you to reach out, and we need a way to communicate with you so that we can move forward."
In a third video, posted Feb. 7, Savannah Guthrie again spoke alongside her brother and sister. This video was posted one day after authorities said they were inspecting a "new message regarding Nancy Guthrie." No details about this latest message have been disclosed. Authorities also have not said if this message was written by the same person behind the previous notes.
"We received your message and we understand," Savannah Guthrie said in the Feb. 7 video. "We beg you now to return our mother to us so that we can celebrate with her. This is the only way we will have peace. This is very valuable to us, and we will pay."
FBI special agent in charge Heith Janke previously confirmed that the FBI consulted with the Guthrie family on the release of their original video addressing their mother's kidnapper.
"While we advise and recommend from a law enforcement perspective, any action taken on any ransom is ultimately decided by the family," he said in a Feb. 5 briefing, adding that it's the "family's decision of what they film and what they put out."
