The FBI’s Phoenix field office released a refined description of a person of interest in the disappearance of Nancy Guthrie and increased the reward to $100,000. The man seen on doorbell footage is about 5’9” to 5’10”, average build, carrying a black 25-liter Ozark Trail Hiker Pack. Authorities say narrowing the description is strategic, not routine. Since early February, investigators have received more than 13,000 tips reported to the FBI and nearly 18,000 calls to the Pima County Sheriff’s Department. Raising the reward from $50,000 to $100,000 highlights urgency and may encourage hesitant witnesses to come forward.

While public involvement is essential, officials admit many tips involve misidentifications or social media-driven theories. Some outreach has even come from “self-described psychics, mystics, and clairvoyants.” Investigators stress that reviewing speculative claims diverts resources from credible leads. Nearly two weeks after 84-year-old Guthrie was reported missing on February 1, the updated description was released to reduce confusion and sharpen focus.

Authorities have requested surveillance and doorbell footage from residents within a two-mile radius of Guthrie’s home. They are concentrating on January 11 (9 p.m.–midnight) and January 31 (9:30–11 p.m.), as well as reports of suspicious vehicles around 10 a.m. A white van has been mentioned but remains unconfirmed. Officials hope this targeted timeline will help reconstruct events and identify meaningful patterns.

A glove found about 1.5 miles from Guthrie’s home is undergoing fingerprint and DNA testing. However, investigators caution that discovery does not equal confirmation. Authorities have also questioned individuals, including Carlos Palazuelos, 36, who was released without charges after cooperating.

The FBI says its priority remains bringing Nancy Guthrie home safely. The refined description and increased reward are tactical steps designed to generate focused, credible information while avoiding speculation.
