Fresh search activity has reportedly been spotted behind Nancy Guthrie’s Tucson home, months after investigators first combed the area. A neighbor told Fox News Digital that she recognized FBI personnel returning to the desert brush near Guthrie’s property shortly before the six-month mark of her disappearance.

This time, the landscape itself may be part of the reason investigators are taking another look. A retired Pima County sheriff’s lieutenant said the intense monsoon rains that hit Tucson could have shifted rocks, soil and other debris, potentially changing areas that had already been searched. He suggested that floodwater may have exposed or moved material that investigators could not previously see.

The reported return to the area comes as the investigation continues to search for answers about what happened to the 84-year-old. The FBI says Guthrie was last seen at her Catalina Foothills residence on January 31, 2026, and considers her a vulnerable adult. The agency is offering a reward of up to $50,000 for information leading to her recovery or the arrest and conviction of anyone responsible.

Investigators have also been examining extensive video and other evidence connected to the disappearance. Authorities recently released two ransom notes, hoping members of the public might recognize the distinctive writing or language and provide a lead. One note demanded cryptocurrency, while another claimed Guthrie had died, although authorities have not publicly confirmed her fate.

There is an important uncertainty surrounding the latest reported search. While a neighbor said she saw investigators returning to the brush, a Pima County Sheriff’s Department spokesperson told Fox News Digital that task-force investigators had not recently returned to the area. The FBI also had not publicly confirmed the reported activity at the time of the report.

That discrepancy has only added to the questions surrounding the renewed activity. Whether the agents were responding to a specific lead, conducting another systematic search, or simply reassessing terrain changed by the monsoon remains unclear from the publicly available information.
