Forensic experts weigh DNA evidence and blood trail clues six weeks after disappearance of Nancy Guthrie

 March 16, 2026

Nancy Guthrie, the mother of Today show co-host Savannah Guthrie, has been missing for almost six weeks after she was last seen at her Arizona home on January 31. She was reported missing the following day. Authorities believe she was kidnapped, and drops of her blood were found on the front porch of her house.

The FBI last month released surveillance images of a masked man on Nancy Guthrie's porch on the night she disappeared. Authorities have not publicly identified the person, whom they called a suspect, but described him as a male about 5-foot-9 or 5-foot-10 with an average build carrying a 25-liter Ozark Trail Hiker Pack backpack. Alleged ransom notes were sent to multiple news outlets. The family is offering a $1-million reward for information leading to her recovery, with a separate reward of more than $200,000 for information about her whereabouts or that could lead to the arrest and conviction of anyone involved.

Nancy Guthrie also needs vital daily medication, adding an urgent medical dimension to an already desperate situation.

What forensic experts see in the evidence

This week, retired FBI agent Maureen O'Connell offered a striking analysis of the blood evidence found at the scene, telling NewsNation's Brian Entin that the pattern of the droplets suggests Guthrie did not leave on her own.

"What I do believe is she was carried out. I don't believe she walked out. I believe she was carried out by two people and I say that because of the blood droplets, the fact that there's no void, the fact that there's no footprints, it's almost like two guys carried her and her head tilted in some way shape or form and it just came out right there."

That analysis, if accurate, reshapes the picture considerably. It implies planning, coordination, and at least two perpetrators. It also suggests violence occurred inside the home before Guthrie was removed from it.

Meanwhile, April Stonehouse, a forensics professor at Arizona State University and a former DNA analyst for government crime laboratories, told Entin she was "hopeful" investigators would find usable DNA samples from the scene. She noted that blood, semen, and saliva are the most useful substances for DNA analysis and described the presence of biological evidence as "a good thing" for the investigation.

Stonehouse acknowledged the limitations, noting that "you are at the mercy of what the suspect left behind," but said investigators would be looking for items that they think the suspect handled or used.

"I would be hopeful that they found at least a few items of evidence. It's just a matter of locating it and finding it."

She also referenced the use of DNA analysis in the Golden State killer case, a reminder that even cold trails can eventually yield identifications when the forensic work is thorough.

The investigation narrows its focus

On February 27, the Pima County Sheriff's Department issued a statement signaling a shift in how it is allocating resources to the case, according to Newsweek:

"This remains an active investigation and will continue until Nancy Guthrie is located or all leads have been exhausted. The Pima County Sheriff's Department is refocusing resources to detectives specifically assigned to this case. As leads are developed and resolved, resource allocation may fluctuate. PCSD will maintain a patrol presence in the Guthrie neighborhood."

Read that carefully. "Refocusing resources to detectives specifically assigned" is bureaucratic language for tightening the circle. It can mean the department is moving from a wide canvas to a more targeted pursuit, which could indicate they have leads worth concentrating on. It could also mean exactly what critics might fear: the visible, large-scale response is being scaled back.

Either way, six weeks into a kidnapping case with blood evidence, surveillance footage of a suspect, and no recovery, the pressure on law enforcement is enormous. The public has a right to expect urgency that matches the severity of the crime.

A family holding on

Last week, Savannah Guthrie posted on Instagram with a message that was equal parts gratitude and plea:

"We feel the love and prayers from our neighbors, from the Tucson community and from around the country.…Please don't stop praying and hoping with us. bring her home."

There is nothing political about a daughter asking the country to help find her mother. There is nothing partisan about the expectation that law enforcement will devote every available resource to bringing a kidnapped woman home alive. But the case raises questions that conservatives have been asking for years about public safety, the adequacy of local law enforcement resources, and whether communities across America can count on swift and sustained investigative attention when violent crime strikes.

It seems as though despite the time that has passed, someone knows something about what happened to Nancy Guthrie. The question is, will investigators discover it before it's too late?
