The FBI has released an updated description of a person of interest in the Nancy Guthrie investigation and has doubled the reward, aiming to encourage tips that could advance the search and bring critical information forward.

The Federal Bureau of Investigation’s Phoenix office has released an updated description of a person seen in doorbell camera footage connected to the disappearance of Nancy Guthrie and increased the reward for information leading to her recovery to $100,000. The individual is described as a man approximately 5 feet 9 inches to 5 feet 10 inches tall, with an average build, carrying a black 25-liter Ozark Trail Hiker Pack. Officials said the refined description is intended to focus public tips and reduce the high volume of unverified information received.

Since early February, the FBI has logged more than 13,000 tips, while the Pima County Sheriff’s Department reported nearly 18,000 calls. Authorities acknowledged that many submissions, including outreach from psychics and clairvoyants, have complicated efforts to prioritize actionable leads. Nearly two weeks after Guthrie, 84, was reported missing on Feb. 1, investigators are carefully reviewing every credible piece of information.

Law enforcement is asking neighbors within a two-mile radius of Guthrie’s home to submit doorbell or surveillance footage from key dates and times in January, particularly late evening hours. An unconfirmed tip involving a white van is also under review. Investigators have recovered potential physical evidence, including a glove found about a mile and a half from her residence, which is undergoing forensic testing for fingerprints, DNA, hair, and fibers.

The FBI emphasized that bringing Guthrie home safely remains the top priority. Officials hope the increased reward and clearer suspect description will generate reliable leads while ensuring the investigation remains thorough, focused, and fair.
