Over 100 days have passed since Nancy Guthrie, the mother of Today co-host Savannah Guthrie, disappeared from her residence in Tucson, Arizona.
A retired FBI agent is now disputing the assumptions surrounding the single strand of hair that has been publicly associated with the case, contending that it is highly unlikely to be the sole piece of forensic evidence gathered, Newsweek reported.
Former FBI agent questions Pima County Sheriff’s probe
In an extensive interview, former agent Steve Moore expressed criticism regarding the initial management of the crime scene by the Pima County Sheriff’s Department. He raised questions about the implications of Sheriff Chris Nanos’ recent statement, “we’re getting closer,” and elaborated on how the turmoil in leadership could either hinder or expedite the investigation, depending on who is ultimately accountable for the failures noted by deputies.

Nancy Guthrie case: Moore speaks about hair evidence
In a discussion with Brian Entin, the Miami Bureau Correspondent for NewsNation, on his YouTube channel, Moore stated that if investigators were to find a single hair within the residence, “there are probably 10 more” that have not been made public. He further remarked that evidence in significant cases is frequently “invisible” to the naked eye, and that skilled technicians are aware of where to search for fingerprints, skin cells, and trace materials.
The presence of a single hair may represent only a small portion of the overall evidence. According to Moore, the discovery of one hair typically suggests that more are present, implying that investigators probably collected further trace evidence that has yet to be revealed.
Nancy Guthrie update: Expert says hair is not sole piece of trace evidence gathered
Moore stated that the hair discovered within Guthrie’s residence is probably not the sole piece of trace evidence gathered, suggesting it is “very possible” that investigators have obtained significantly more than what has been made public.
“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,” he stated, as per Newsweek.
Initial disarray may have undermined the integrity of the scene. Sergeant Aaron Cross recounted the tumultuous initial hours, marked by inconsistent information from relatives and a lack of effective communication between deputies and the FBI. Moore noted that confusion at a crime scene reflects a breakdown in leadership and readiness.
Leadership inquiries may influence the probe. As recall efforts and political pressure intensify on Nanos, Moore said that the removal of a sheriff during an ongoing case could momentarily hinder progress, yet it might ultimately be beneficial if leadership was implicated in the issue.
The discovery of remains would transform the case. Moore stated that if Guthrie’s body were to be discovered, even after several months, the site itself would yield a “treasure trove” of evidence, ranging from tire tracks to environmental indicators.
