Retired FBI Special Agent Steve Moore says the FBI is battling a 'troubling' lack of usable leads in theNancy Guthrie case in Tucson, Arizona, nearly three months after the 84‑year‑old disappeared on 31 January after leaving a family dinner and driving back to her home.

Speaking to NewsNation's Brian Entin, Steve Moore suggested investigators in the Nancy Guthrie case are drowning in data that, so far, has not taken them where they need to go.

'If they had significant information, they would have more progress on the case,' he said. He suggested that if the public could see the internal case files, they would probably find 'so much information that ultimately turned out to be of little or no value, but seemed so, so promising at the time.'

Moore argued that releasing all of that unfiltered detail would almost certainly ignite furious speculation online. In his words, it would 'light a fire on social media' without actually helping detectives.

As of this reporting, the FBI has not publicly commented on Moore's assessment of the investigation, and there is no independent confirmation of the volume or quality of the material agents have gathered.

A key unresolved question in the Nancy Guthrie investigation iswhether a single abductor was responsible or whether more than one person was involved. Moore said both scenarios remain credible.

'Some people very, very rightly say that it's hard to imagine a single person doing this. But at the same time, you can't put your weight down on the ice,' he told Entin.

He called the FBI 'the finest investigative organisation in the world' and admitted that if they are struggling, it would be 'arrogant' for commentators to claim they would do better.

Statistically, he believes the odds lean towards two perpetrators, but history complicates that neat answer. Many notorious kidnapping cases, he pointed out, have ultimately turned out to involve a lone offender, particularly when children or infants are targeted and held against their will.

Doorbell video from Guthrie's home, released by the FBI and the Pima County Sheriff's Department, shows an armed, masked individual at her front door on 1 February apparently interfering with the camera.
