More than 100 days after Nancy Guthrie vanished from her Tucson, Arizona, home, a retired FBI agent is raising pointed questions about the single strand of hair publicly linked to the case, and about the way the Pima County Sheriff's Department handled the scene in the critical first hours after she disappeared.
Former FBI agent Steve Moore, speaking in an interview with NewsNation correspondent Brian Entin on Entin's YouTube channel, said the lone hair that has dominated public discussion almost certainly represents a fraction of the forensic material investigators actually collected. His blunt assessment carries an implicit rebuke of both the information authorities have shared and the way they secured the scene.
As Newsweek reported, Moore told Entin that finding a single hair and nothing else would defy basic forensic probability.
"Imagine the odds of a person coming into a crime scene, losing only one hair, and you find it. That's not likely. If you find one hair, there are probably 10 others that you've missed."
The implication is clear: investigators likely hold far more forensic evidence than the public knows about. Moore said the evidence that ultimately convicts people is "frequently invisible" and urged patience, noting that fingerprints cannot be seen from more than a foot away. "There is evidence everywhere," he said. "Hopefully, they have way more than just the hair."
Moore did not limit his comments to the hair. He leveled sharp criticism at the early handling of the scene at Guthrie's home, where Sergeant Aaron Cross described the first hours as a period marked by uncertainty, emotional family members, conflicting information, and unclear direction between deputies and the FBI.
For Moore, that confusion pointed to a leadership failure.
"You're not allowed to have confusion at a crime scene. If there's confusion, it means nobody's in charge who knows what they're doing."
He called it "a sign of inadequate preparation." That assessment lands hard given the gravity of the case. Authorities have described Nancy Guthrie's disappearance as a violent, targeted kidnapping. Evidence inside the residence, including blood later confirmed to be hers, made it immediately clear she did not leave voluntarily, investigators said. Her phone, medication, and personal belongings were still inside.
Moore acknowledged that managing distraught relatives at an active scene is difficult but said investigators should have moved the family to a neutral location rather than risk contaminating evidence. "You can't just say, 'We can't talk in here,'" he said. "But you can constrain everything into a neutral site, someplace that isn't going to screw up the investigation."
Nancy Guthrie, the 84-year-old mother of Today co-host Savannah Guthrie, was last seen the night of January 31, when her son-in-law Tommaso Cioni dropped her off around 9:50 p.m. She failed to appear for a scheduled church livestream the next morning. A concerned church member alerted the family, and relatives arrived at the home shortly before noon to find her gone.
Federal investigators later released surveillance video showing a masked, armed intruder tampering with Guthrie's doorbell camera around 1:47 a.m. The FBI recovered backend data and released still images and video showing the person wearing gloves and a backpack, and carrying a weapon. That release of surveillance images marked one of the few concrete public developments in a case that has otherwise produced more questions than answers.
Within hours of the family's 911 call, the investigation escalated into a multi-agency effort involving the Pima County Sheriff's Department, the FBI, U.S. Customs and Border Protection, and search-and-rescue teams.
Multiple ransom notes surfaced, with several media outlets receiving alleged demands for cryptocurrency. Their authenticity remains unclear. One California man was arrested for posing as an abductor, but officials said his scheme was unrelated to the broader case. A pair of gloves initially thought to match those worn by the suspect were seized, but DNA on them was traced to a restaurant worker and ruled out. Investigators say other DNA evidence remains under analysis.
Savannah Guthrie took leave from hosting Today to help search for her mother. She has since returned to the program even as the case remains open and no verified proof of life has been received.
Pima County Sheriff Chris Nanos, the top elected official whose department holds lead local authority, now faces a recall effort and pressure from county commissioners. In a recent interview with People, Nanos confirmed he has stepped back from direct interaction with the Guthrie family. Communication, he said, now flows through his detectives and the FBI.
"I personally am not" in contact with the family, Nanos told People. "If they need the family for anything, they get in touch with them. It works both ways." He added: "She doesn't need to talk to me."
That posture drew notice. Moore questioned the meaning behind a recent Nanos remark that investigators are "getting closer," saying the phrase lacked specificity.
"I think he didn't feel like saying 'same old, different day.' I would need something more than that for it to mean anything significant to me."
Moore's skepticism reflects a broader concern: whether the sheriff's office has the capacity and the leadership to manage a case of this complexity. Reports have pointed to disputed timeline details and investigative friction that have dogged the department since the case began.
Moore outlined how the leadership turmoil around Nanos could cut both ways. If the recall effort or political pressure leads to a change at the top, a new sheriff would face a learning curve. "There is going to be a learning curve that's going to stunt the growth of the investigation for a little while," Moore said.
But he suggested the tradeoff might be worth it if the current leadership is responsible for the breakdowns deputies have described. In that scenario, Moore said, "that would be a very short time of stumbling and a vast improvement going forward."
The FBI has taken on a central operational role, handling forensic analysis, digital evidence recovery, and much of the family communication. Detectives within the sheriff's department continue to work alongside federal agents, reviewing surveillance footage, processing tips, and coordinating with the family when necessary. A former FBI agent has previously speculated that certain decisions by the sheriff's office could signal investigators are closer to an arrest than the public realizes.
Moore also offered a practical observation about the geography of the case. If Nancy Guthrie was taken from her home, the suspect's vehicle and route would themselves be a source of forensic evidence. "It would be another treasure trove of evidence," he said, adding that perpetrators do not typically drive vast distances to dispose of a victim. "Somebody's not going to drive a hundred miles one direction to dump a body and then come back. They just don't do that."
The list of unanswered questions remains long. No confirmed motive has been established. The identities of detained persons of interest have not been disclosed. The status of DNA evidence still under analysis is unknown. And the authenticity of the ransom notes, some demanding cryptocurrency, has never been resolved publicly.
Nanos himself has confirmed the official view of the case. "At this point, investigators believe she was taken from her home against her will," he said.
Anyone with information is urged to contact law enforcement or submit tips through the FBI.
More than 100 days in, the Guthrie family is still waiting. The public is still guessing. And the question is whether the people running this investigation have been equal to the task from the start, or whether the confusion at the scene that first morning set a tone that has never been corrected.
