Authorities searching for Nancy Guthrie have expanded their investigation, now interviewing individuals who previously worked at her home in Tucson, as the case enters a new phase.

Investigators confirmed that Guthrie, the mother of Savannah Guthrie, remains missing. Law enforcement officials say they are speaking with people who assisted with cooking, cleaning, and yard work at her residence in an effort to better understand her daily routine and any recent changes leading up to her disappearance.

According to authorities, these interviews are part of a standard investigative process in missing person cases. Individuals who regularly had access to the home or interacted with Guthrie are often questioned to help establish timelines, routines, and any unusual observations that may have occurred prior to the disappearance.

Officials emphasized that speaking with household workers does not imply wrongdoing. Rather, investigators are attempting to gather as much information as possible to piece together Guthrie’s movements and habits.

The investigation is being led by the Pima County Sheriff’s Office, which has stated that the case remains active and ongoing. Detectives are continuing to pursue multiple avenues simultaneously as they attempt to determine what happened.

Authorities have not disclosed how long Guthrie had employed assistance at her home or how frequently those individuals were present. They also have not released details about what information, if any, has been obtained from the interviews so far.

The decision to interview people familiar with Guthrie’s household routine follows earlier developments in the case that raised concerns about the circumstances of her disappearance. Investigators previously indicated that there were unsettling elements inside the home, prompting fears that she may not have left voluntarily.

Law enforcement officials say understanding Guthrie’s normal schedule is critical. Those who worked in or around the home may be able to confirm when she was last seen, whether anything appeared out of place, or whether there were unexpected visitors or disturbances.

Community members in Tucson continue to watch the case closely. The involvement of people who regularly worked at the residence has added a new layer of attention, as investigators work methodically to rule out possibilities and narrow their focus.

Authorities have reiterated that Guthrie is still considered a missing person. They have not announced any suspects or persons of interest, and no arrests have been made in connection with her disappearance.

Police are also continuing to ask residents in the area to review home surveillance footage, including doorbell cameras and security systems. Investigators believe that any visual evidence, even if it seems insignificant, could provide valuable clues.

Family members have remained largely private as the investigation unfolds. Officials acknowledge the emotional toll such cases take on loved ones, particularly as days pass without answers.

Law enforcement agencies stress that missing person investigations often evolve over time. As new information emerges, investigators adjust their focus and pursue additional leads, including speaking with individuals who had regular contact with the missing person.

At this stage, authorities have not indicated whether the interviews with household workers have produced any breakthroughs. They continue to urge the public to remain vigilant and to report anything unusual that may be connected to Guthrie’s disappearance.

For now, the search for Nancy Guthrie continues. Investigators say every detail matters as they work to uncover the truth and determine what led to her disappearance from her Tucson home.
