The search for Nancy Guthrie, mother of Today show host Savannah Guthrie, intensified as authorities revealed that they have received more than 18,000 calls regarding her disappearance. This surge in tips coincided with the FBI's release of door camera footage showing a masked individual near her Arizona residence, where she was last seen. The Pima County Sheriff's Office highlighted that nearly 25% of the calls were made within just 24 hours of the video's release, indicating heightened public interest and concern for the elderly woman's safety.

Despite the influx of information, investigators have yet to identify any new suspects linked to the case. A man who was temporarily detained during a traffic stop not far from the Guthrie home was released after questioning, further complicating the investigation. The continued search efforts, which included extensive examinations of roadways and a thorough combing of the desert terrain surrounding the Catalina Foothills, yielded little new evidence to enhance the lead investigators had on the case.

The authorities remain committed to finding Nancy Guthrie, emphasizing the importance of the public's role in bringing new information to light. The case has not only drawn significant media attention due to Savannah Guthrie's high-profile career but also highlights broader concerns about the safety and vulnerabilities of elderly individuals. As the search extends into further parts of Arizona, the hope remains that a breakthrough in the case can be achieved with the community's support and the diligent work of law enforcement personnel.
