New updates have been shared in the case of Nancy Guthrie, who was abducted from her home in Tucson, Arizona, last week.
As previously reported, the 84-year-old mother of Today Show host Savannah Guthrie, vanished from her $1 million home in Tucson, Arizona, last weekend.
It is believed that Nancy was taken against her will after police discovered a trail of her blood outside the door, and that her doorbell camera had been disconnected at 1:47AM on Sunday, shortly before its believed she was removed from her home.
Several ransom notes have since emerged, including one which authorities are taking seriously.
Now, it has been revealed that police are searching a septic tank behind her house, with drone footage showing them opening a manhole cover in the backyard on Sunday.
As reported by the New York Post, three detectives were seen putting a long pole down the manhole, though it has not been revealed what they were looking for.
Police were spotted outside the property at around 11AM, but left empty handed.
Despite receiving a ransom note that they are taking seriously, police have reiterated that they have not identified any suspects or persons of interest.
The ransom note, which was sent to several news outlets, demanded $6million in bitcoin, with a deadline of 5PM local time on Monday.
The letter is said to include details about Nancy's home as well as a threat to her life if the deadline is not met.
Savannah shared a video to the captors on social media, saying: "We received your message, and we understand.
"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.”
Savannah had earlier shared another video alongside her two siblings - brother Camron and sister Annie - pleading: "We need to know without a doubt that she is alive and that you have her. We want to hear from you and we are ready to listen. Please reach out to us.
They also addressed her mother directly, holding onto hope: "Mamma, if you're listening, we need you to come home. We miss you."
Nancy was last seen over a week ago she was dropped off at home by her daughter and son-in-law.
She was reported missing on Sunday, February 1, after she failed to show up at a local church.
While she is mentally sharp and able to drive, she has difficulty walking short distances and requires daily medication for high blood pressure, heart issues, and a pacemaker.
Authorities have confirmed that she needs this medication to maintain her health.
Sheriff Chris Nanos of Pima County stated: "Right now, we believe Nancy is still out there. We want her home." However, he added: “We have no evidence she’s okay,” which has only increased concerns about her well-being.
