More than 109 days after Nancy Guthrie vanished from her Tucson home, a retired FBI agent is pushing back on what the public has been told about the forensic evidence - and his assessment changes the picture significantly.
Former FBI special agent Steve Moore sat down with NewsNation's Brian Entin in the last 24 hours and delivered one of the most specific analyses of the case to date. The focus: the single strand of hair that has become the centerpiece of public discussion about where the investigation stands.
Moore's position is direct. One hair is almost certainly not the only hair.
"Imagine the odds of a person coming into a crime scene, losing only one hair, and you find it," he said. "That's not likely. If you find one hair, there are probably 10 others that you've missed." His point is that if investigators recovered even a single strand, the forensic reality of how human hair transfers suggests they very likely have far more evidence than has been disclosed publicly - and that the investigation may be further along than Sheriff Chris Nanos' careful public statements suggest.
Moore also addressed the sheriff directly - and not gently. He described the early handling of the crime scene as "chaotic," raising concern that the Pima County Sheriff's Department's initial response may have complicated the integrity of evidence collected in the critical first hours. He stopped short of saying evidence was lost, but the implication was clear: what happened at that scene in the early morning hours of February 1 still matters, and it may still be affecting where the case stands today.
On Sheriff Nanos' recent "we're getting closer" remark - which drew widespread attention last week - Moore was skeptical. He questioned whether the statement reflected genuine investigative momentum or was intended to manage public frustration as the case passes the 100-day mark with no arrest and no named suspect.
What Moore does believe: evidence is there. "The evidence that convicts people is frequently invisible," he said. "You're not going to see a fingerprint from more than a foot away." He added that if Nancy's remains are ever located, even months later, the site itself would provide what he called "a treasure trove" - tire tracks, environmental patterns, DNA traces - that could finally break the case open.
Nancy Guthrie was known in Tucson as a woman of deep faith - a Catholic who attended Mass regularly, taught Bible study, and was first reported missing when she failed to appear for a Sunday morning church livestream that her loved ones knew she never missed. Her daughter Savannah has leaned publicly on that same faith throughout, asking for prayer on air and on social media in the weeks since her mother disappeared.
Those prayers have not stopped. Neither has the search.
