Nancy Guthrie, an 84-year-old woman, was last seen at her home in the Catalina Foothills area of Tucson, Arizona, on the evening of January 31, 2026. A family member had driven her home after dinner, dropping her off shortly before 10 p.m. She was expected to participate in a church service the following morning, but when she did not appear, someone from the church contacted her family.
Relatives went to Guthrie’s residence to check on her and could not find her anywhere inside or around the property. The family contacted authorities around midday on February 1. From the beginning, her disappearance caused immediate concern because Guthrie had significant difficulty walking, used a pacemaker and required daily medication for a heart condition. Sheriff Chris Nanos said she had no known cognitive impairment and investigators did not believe she had simply wandered away. Her cellphone and other important belongings were found at the residence, making the idea that she had voluntarily left even less likely.
What began as a missing-person search quickly became a suspected abduction investigation. Deputies, search teams, dogs, drones and aircraft searched the surrounding Catalina Foothills terrain, while Guthrie’s home was treated as a crime scene. Investigators reconstructed a troubling sequence of events from electronic records. Her doorbell camera disconnected during the early morning hours of February 1, and roughly three-quarters of an hour later the connection between Guthrie’s pacemaker and an application on her cellphone was also lost. The phone itself remained behind at the house. Authorities eventually recovered previously inaccessible security-camera images showing a masked individual wearing gloves and a backpack outside Guthrie’s front door. The person appeared to be armed and was seen approaching and apparently interfering with the doorbell camera. Investigators later determined that images of what appeared to be the same masked individual had been recorded at the residence before the night Guthrie disappeared, raising the possibility that whoever was responsible had visited or observed the property beforehand.
Physical evidence added to the seriousness of the investigation. Blood identified as Guthrie’s was reported on the porch, and investigators collected additional biological evidence from the residence for laboratory testing. A glove discovered away from the house appeared consistent with gloves worn by the masked person in the surveillance footage and contained DNA, but testing did not produce a match in the national CODIS database. Other biological material recovered from the property also underwent extensive analysis. By the summer, investigators said hair that had been examined had not identified a suspect, while a complicated mixed DNA sample containing material from several individuals remained under review by laboratories, including the FBI laboratory in Quantico. Despite the forensic work, investigators had not publicly connected the available DNA evidence to a specific person.
The case became even more disturbing when communications claiming responsibility for Guthrie’s disappearance began reaching news organizations and her family. One message claimed she was being held captive and demanded millions of dollars in Bitcoin, while providing details about the scene that investigators considered significant. A later message from someone claiming to be involved alleged that Guthrie had died after being taken because those responsible had underestimated the seriousness of her heart condition and claimed that she had been buried somewhere outdoors. Authorities have never publicly confirmed that claim as proof of Guthrie’s fate, and they have continued trying to locate her. Months later, the Pima County Sheriff’s Department released the two communications to the public, hoping that someone might recognize the writer’s distinctive vocabulary, sentence structure or manner of expression. Investigators emphasized that even apparently insignificant information about someone’s behavior, statements or unusual activity around the time of the disappearance could be important.
The enormous publicity surrounding Guthrie’s disappearance also attracted people attempting to exploit the family. Federal authorities arrested California resident Derrick Callella after accusing him of sending a separate fraudulent ransom demand seeking Bitcoin. Officials made clear that his alleged communication was an imposter demand and was not the ransom communication investigators were taking seriously in connection with the disappearance itself. At another point, a man was detained for questioning during investigative activity south of Tucson but was subsequently released without charges. Neither development resulted in an arrest for Guthrie’s actual abduction, and authorities have not publicly identified the masked individual recorded at her home.
As the months passed, Nancy’s family continued pleading for answers while investigators pursued digital records, surveillance images, forensic evidence and thousands of tips. The FBI increased its reward for information leading to Guthrie’s location and/or the arrest and conviction of those responsible, while her family also offered a substantial reward. More than seven months after she vanished, the FBI continued listing Nancy Guthrie among its kidnapping and missing-person cases, and authorities had announced no arrest of anyone accused of taking her. Her family has continued asking anyone who knows something to come forward, their appeals increasingly focused simply on learning where Nancy is and bringing her home. What began when a beloved mother and grandmother failed to appear for church has developed into a prolonged suspected-abduction investigation involving a vulnerable woman apparently taken from the safety of her own Catalina Foothills home, a masked person captured on surveillance, unexplained biological evidence, disputed ransom communications and an exhaustive search that has yet to provide the Guthrie family with the answer they have been seeking: what happened to Nancy, who took her, and where she is now.Last Seen: Feb 1, 2026
