The FBI is now jointly investigating the case and offering a $50,000 reward.
The Guthrie family has issued another video message, directed toward the potential kidnappers of their mother, urging them to reach out and prove they have Nancy Guthrie, as the 84-year-old's whereabouts remain unknown days after she is believed to have been abducted from her Arizona home.
"Whoever is out there holding our mother, we want to hear from you," Camron Guthrie, the brother of "Today" show host Savannah Guthrie, said in a video message posted Thursday on behalf of the family. "We haven't heard anything directly. We need you to reach out and we need a way to communicate with you so we can move forward."
But first, Camron Guthrie continued, "we have to know that you have our mom."
He closed the brief message saying, "We want to talk to you, and we are waiting for contact."
No suspect or person of interest has been identified in the case, Pima County Sheriff Chris Nanos said during a press briefing on Thursday.
"Right now, we believe Nancy is still out there," Nanos said. "We want her home."
The sheriff said authorities are operating from a position that Nancy Guthrie is alive, and "we're going to continue thinking that way until we find her."
The FBI announced Thursday it is now jointly investigating the case and offering a $50,000 reward for information leading to the recovery of Nancy Guthrie and/or the arrest and conviction of anyone involved in her disappearance.
The latest message follows a video posted on Wednesday in which Savannah Guthrie addressed the reports of a ransom letter that had been sent to media outlets and directly spoke to her mother's potential kidnappers.
"As a family, we are doing everything that we can. We are ready to talk. However, we live in a world where voices and images are easily manipulated. We need to know without a doubt that she is alive and that you have her," Savannah Guthrie said in the video, alongside her brother and sister. "We want to hear from you and we are ready to listen. Please reach out to us."
Nancy Guthrie, 84, was last seen at her home in the Catalina Foothills area, north of Tucson, on Saturday night, according to the Pima County Sheriff's Department. She was dropped off home shortly before 10 p.m. after having dinner with her family, he said. Her family reported her missing on Sunday around noon local time after she failed to show up to church, authorities said.
On Thursday Nanos provided new details of activity after Nancy Guthrie was last seen. At approximately 1:47 a.m. Sunday, the doorbell camera at her home disconnected and authorities do not have it in their possession, he said.
At 2:12 a.m., the software detected a person on a camera, but there is no video available because there isn't a subscription, he said, adding, "Could that be an animal? I imagine that's possible. We don't know that."
At 2:28, her pacemaker app "shows that it was a disconnect from the phone," he said.
Nanos confirmed Nancy Guthrie's blood was found on her porch. He did not confirm if any cameras were smashed or destroyed around the house, or if there was any forced entry.
There is a possibility her disappearance has "nothing to do with a kidnapping," and it is unclear whether Nancy Guthrie was targeted or not, Nanos said Thursday.
"We cover all angles. We're not going to dismiss something," he said.
The sheriff's department has said it is reviewing possible ransom notes as part of the investigation and if they are legitimate.
One letter was sent to several local and national media outlets, Heith Janke, special agent in charge of the FBI's Phoenix office, confirmed on Thursday. The letter made a monetary demand by 5 p.m. Thursday, and if that wasn't met, a second demand for Monday, according to Janke.
That letter also included details on an Apple Watch and a smashed floodlight, according to Janke, who noted those are details that could have been known to the public.
"But that's why we're taking it serious no matter what, and following the leads on that," he said.
Janke said any action taken on a ransom is ultimately decided by the family.
Janke said one arrest has been made related to an "imposter ransom demand."
The suspect, Derrick Callella, is accused of demanding Bitcoin from members of the Guthrie family, according to a federal complaint.
Callella allegedly sent a text message to both the daughter and son-in-law of Nancy Guthrie on Wednesday that said, "Did you get the bitcoin were [sic] waiting on our end for the transaction," according to the complaint.Â
The text messages were sent two days after a local Tucson media outlet received a ransom demand that listed a Bitcoin wallet address to receive the payment, according to the complaint. They were also sent shortly after Nancy Guthrie's children published a video online asking their mother's kidnappers to contact them, the complaint also noted.
