In the latest twist in the high-profile disappearance of Nancy Guthrie—the 84-year-old mother of NBC "Today" show co-host Savannah Guthrie—law enforcement officials detained a man late Tuesday evening during a traffic stop in Rio Rico, Arizona, just north of the U.S.-Mexico border.

The Pima County Sheriff's Department confirmed the action in a brief statement on X, noting that deputies conducted the stop south of Tucson and that the individual is now being questioned "in connection to the Nancy Guthrie investigation." Additional details were promised as they become available, but no name, charges, or further identification has been released.

Rio Rico, a quiet community in Santa Cruz County roughly 10 miles from the Nogales border crossing, became the focal point after the detention. Sources familiar with the matter have told sources that the stop occurred in this border-adjacent area, prompting immediate speculation about travel patterns or potential escape routes—though authorities have offered no confirmation on motive or intent.

The move follows the FBI's Tuesday release of doorbell camera footage from Guthrie's Catalina Foothills home, captured around 1:47 a.m. on February 1. The video shows a masked figure in dark clothing, wearing gloves and what appears to be a handgun holster, tampering with the camera shortly before Guthrie vanished. Her pacemaker lost connection with her cellphone about 41 minutes later, and her phone was later found inside the residence. Blood evidence on the porch matched her DNA profile, solidifying the case as an abduction.

Investigators have not publicly linked the detained man to the masked individual in the surveillance images, but the timing has fueled intense public interest. Following the traffic stop, a court-authorized search was launched in the Rio Rico vicinity, with law enforcement—supported by Santa Cruz County deputies—continuing operations well into the night. Reports of heightened activity at local properties circulated on social media, though officials have not detailed what, if anything, was recovered.

Nancy Guthrie was last seen at her home north of Tucson on the evening of January 31st and reported missing February 1st after missing church services. The investigation, led by the Pima County Sheriff's Department with heavy FBI involvement, treats the matter as a kidnapping. A separate individual was earlier arrested for an unrelated fake ransom scheme involving extortion demands sent to media outlets.

The FBI's $50,000 reward remains in effect for credible information leading to Guthrie's safe recovery or the arrest and conviction of those responsible.
