Pima County Sheriff Chris Nanos, speaking to reporters at a news conference in the Tucson area, said the 84-year-old woman traveled to her daughter’s home for dinner at approximately 5:32 p.m. Saturday. Authorities located and spoke with the Uber driver who took Guthrie to her daughter’s house, Nanos said. He did not elaborate on what investigators learned. Guthrie’s family dropped her back at her house at 9:48 p.m., when the garage door opened. The garage door closed two minutes later, Nanos said. #embed-20260205-nancy-guthrie-timeline iframe {width: 1px;min-width: 100%}var pymParent = new pym.Parent('embed-20260205-nancy-guthrie-timeline', 'https://dataviz.nbcnews.com/projects/20260205-nancy-guthrie-timeline/index.html', {title: '', parenturlparam: '', parenturlvalue: ''}); In the early hours of Sunday, at approximately 1:47 a.m., Guthrie’s home’s doorbell camera disconnected, according to the sheriff’s department sequence of events. Then, at 2:12 a.m., software detected a person on camera, but there is no video available, Nanos said. Sixteen minutes later, at 2:28 a.m., Guthrie’s pacemaker app showed it had disconnected from her phone. The Guthrie family checked on her at 11:56 a.m. after she did not show up at Sunday morning church services. The family placed a 911 call to the sheriff’s department at 12:03 p.m. and reported her missing, and the sheriff’s patrol arrived shortly after, at 12:15 p.m. Reports indicate that ransom notes referencing Guthrie have been sent to at least three news outlets. NBC News has not seen copies of the notes, and no law enforcement agency has substantiated news reports about them. Heith Janke, FBI Phoenix’s special agent in charge, told reporters that one of the reported ransom notes had a deadline of 5 p.m. Thursday. He said there was a second deadline on Monday, Feb. 9. Nanos reiterated that authorities have not identified a suspect or a person of interest in the case, which has drawn national attention. “We’re not there yet,” the sheriff told reporters. He also confirmed that blood found on the porch outside Guthrie’s house tested positive for her DNA. Investigators believe Guthrie is “still out there” and remain committed to bringing her home safely. Donald Trump 22 hours ago Trump spoke to Savannah Guthrie as search for her mother continues Today Show Feb 4 Search for ‘TODAY' co-anchor Savannah Guthrie's mom stretches into fourth day Reports of ransom notes The FBI on Thursday detailed ransom letters that were reportedly sent to local media and national outlets. “As with every lead, we are taking it seriously. We are in communication with the family. While we advise and recommend, from a law enforcement perspective, any action taken on any ransom is ultimately decided by the family,” Janke said. There was no proof of life or other demands included in the letter, he told reporters. Janke added that one of the reported ransom notes “had facts associated with a deadline with a monetary value they were asking for.” He added that one also “talked about an Apple watch, and one talked about a floodlight.” “We’re not going to go into specifics,” he added. “It’s very important that we keep this investigation moving forward, and we don’t want to put more facts out there that others can use to try to profit from this.” Reports indicate that ransom notes have been sent to three news outlets referencing Guthrie. NBC News has not seen copies of them, and no law enforcement agency has substantiated the reports. Jon Edwards, the assistant special agent in charge of the FBI’s Tucson office, said at a press conference Feb. 3 that the bureau is assisting on the case by downloading and analyzing cell phone data and cell phone tower information, conducting interviews and providing investigative support.

What Savannah Guthrie has shared since her mother’s disappearance Savannah, whom the sheriff said is in Arizona, shared a video late Feb. 4 on Instagram alongside her siblings with a plea for the safe return of their mother. “Mommy, if you are hearing this, you are a strong woman, you are God’s precious daughter,” Savannah said. “We believe and know that even in this valley, He is with you. Everyone is looking for you, Mommy, everywhere. We will not rest, your children will not rest, until we are together again.” Savannah’s first statement came the morning of Feb. 2. “On behalf of our family, I want to thank everyone for the thoughts, prayers and messages of support,” she said. “Right now, our focus remains on the safe return of our dear mom. We thank law enforcement for their hard work on this case and encourage anyone with information to contact the Pima County Sheriff’s Department at (520) 351-4900.” She also shared an Instagram post late Feb. 2 in which she asked for people to pray for her mother’s return. What officials have said about Nancy Guthrie’s health Nancy Guthrie does not have cognitive issues, Nanos said at a Feb. 2 press briefing, but has physical challenges and is in need of medication that can be fatal if not received within 24 hours. “She is very limited in her mobility. We know she didn’t just walk out of there,” Nanos said. “There were other things at the scene that indicate that she did not leave on her own.” Nanos added that Guthrie “could not walk 50 yards by herself.” Other details police have released Nancy Guthrie’s family told police they were alerted to her disappearance when they received a call from someone at their local church saying she was not there. The family then went to her house and searched for her before calling police. Authorities are in possession of Nancy Guthrie’s cell phone, according to Nanos. She lives alone and had house staff, some of whom have been in touch with law enforcement, according to the sheriff. Police do not know if Nancy Guthrie was targeted because she is Savannah’s mother and are not aware of threats aimed at Savannah after speaking with her, Nanos said. Nanos added that he does not believe the public is in any danger. Nancy Guthrie is described as 5 feet, 5 inches tall, weighing 150 pounds, with brown hair and blue eyes. Her family last saw her at home around 9:30 p.m. to 9:45 p.m. on Jan. 31, Nanos said. Officials had been searching using drones, a helicopter, an airplane, search-and-rescue dogs and volunteers before the search was called off on Feb. 2 due to police viewing her disappearance as a crime investigation.
