Authorities investigating the disappearance of Nancy Guthrie are concentrating on a narrow early-morning window in which they believe she may have been removed from her Tucson home.
According to investigators, available evidence suggests Guthrie may have been taken between approximately 2:30 a.m. and 3:00 a.m. on Sunday, February 1, 2026. While officials have not confirmed whether foul play occurred, the working theory guiding the investigation is that she was forcibly removed during that timeframe.
Based on this estimated window, investigators believe that if she was transported from the residence, a suspect could have traveled as far as a two-hour driving radius from Tucson before daylight. Twilight began at approximately 5:40 a.m., leaving several hours of darkness.
A two-hour radius from Tucson covers vast stretches of southern Arizona, including remote desert terrain, mountainous regions, rural roadways, and sparsely populated areas. Law enforcement has not publicly identified a specific search zone but has confirmed that remote locations remain a key focus.
The investigation is being conducted jointly by the Federal Bureau of Investigation and the Pima County Sheriff’s Department.
Federal authorities recently released four surveillance images recovered from Guthrie’s home. The images include a masked individual believed to be connected to the case. Investigators also disclosed that certain recording devices may have been removed from the residence, complicating early evidence recovery. Over eight days, digital forensic specialists worked with private-sector technology partners to restore potentially corrupted or inaccessible data.
Officials emphasize that the case remains classified as a missing person investigation. They have not confirmed Guthrie’s death.
Investigators continue to stress that secondary locations — if any were used — could still contain critical forensic evidence. Trace materials, including DNA, may remain recoverable and could prove pivotal.
Anyone with information, including reports of unusual vehicle activity or suspicious behavior during the early hours of February 1, is urged to contact the FBI at 1-800-CALL-FBI. The investigation remains active.
