Person Detained in Disappearance of Nancy Guthrie as FBI Releases Surveillance Images

TUCSON, Ariz. - A person has been detained for questioning in connection with the disappearance of Nancy Guthrie, a development that marks a significant turn in a case that’s gripped the Tucson community for over a week.

According to individuals familiar with the investigation, the person is not currently facing charges, but authorities are actively pursuing leads. The FBI has also released surveillance images from the night Guthrie went missing, taken from her home in Tucson. The images are part of a broader effort to piece together the timeline of her disappearance.

Guthrie was last seen at her residence, and the case has since evolved into a high-priority investigation involving local law enforcement and federal authorities. The Pima County Sheriff’s Department issued a missing person alert for Guthrie earlier this month, prompting a wide-ranging search effort that has included aerial surveillance, ground searches, and interviews with neighbors and acquaintances.

The FBI’s images show Guthrie at home on the night she vanished, though officials have not disclosed who else may have been present or any specific details about the footage. A spokesperson emphasized that the images are being released in hopes the public may recognize something-or someone-that could help investigators.

Authorities have described the case as "complex" and "active," with multiple agencies collaborating to track down every possible lead. The detained individual is being questioned as part of that broader investigation, though officials have not released their name or confirmed their relationship to Guthrie.

The search for Guthrie has drawn significant attention, not just locally but nationally, as the FBI joined the case and began coordinating efforts with the Pima County Sheriff’s Office. Investigators have canvassed the neighborhood, collected forensic evidence from Guthrie’s home, and reviewed hours of surveillance footage from nearby residences and businesses.

Officials have confirmed that Guthrie’s phone and other personal items were found inside her home, and there were no immediate signs of forced entry. That detail has added to the mystery surrounding her disappearance and raised questions about whether she left voluntarily or was taken under duress.

In a statement, the FBI reiterated its commitment to solving the case and urged anyone with information to come forward. “We believe someone knows something,” the agency said. “Even the smallest detail could be critical.”

Meanwhile, Guthrie’s family continues to hold out hope for her safe return. They’ve asked for privacy but have also expressed gratitude for the public’s support and the tireless work of law enforcement.

As the investigation continues, authorities are urging the public to remain vigilant and to report any information that could assist in locating Guthrie or clarifying the circumstances of her disappearance. The case remains open and active, with more updates expected in the coming days.
