DNA Evidence From Nancy Guthrie Case Yields No Matches

The search for answers in the Nancy Guthrie disappearance has hit a troubling dead end as [DNA evidence from gloves found near her home failed to produce any matches](https://abcnews.com/US/video/dna-glove-found-nancy-guthries-home-undergoing-testing-130224530) in the FBI's criminal database, authorities revealed Tuesday.

The Pima County Sheriff's Department confirmed that DNA from the black gloves discovered approximately 2 miles from Guthrie's Tucson residence did not yield any hits in the Combined DNA Index System (CODIS), a comprehensive database containing DNA profiles from convicted offenders and crime scenes across the nation.

The gloves had initially offered investigators hope for a breakthrough. Preliminary testing revealed DNA from an unknown male on the gloves, which appeared to match those worn by a suspicious person captured on security video outside Guthrie's home. The discovery seemed to provide the first tangible link between physical evidence and the 84-year-old mother of "TODAY" co-anchor Savannah Guthrie's disappearance.

However, the lack of database matches means the DNA profile belongs to someone with no prior criminal record in the system, significantly complicating the investigation. The sheriff's department emphasized that "there have been no confirmed CODIS matches in this investigation" and that the glove DNA "did not match DNA found at the property."

The setback comes as investigators continue analyzing additional DNA evidence recovered from Guthrie's residence. The DNA found at the property is still being analyzed and requires further testing, though authorities have not disclosed what this evidence might reveal or how it relates to the case.

The investigation has generated massive public interest, with law enforcement fielding between 40,000 to 50,000 leads from concerned citizens nationwide. Despite this overwhelming response from the public, the failure of the most promising physical evidence to produce actionable results underscores the challenges facing investigators.

The DNA testing process, which involves sending evidence to specialized laboratories, can take weeks or months to complete. The glove evidence was sent to a private lab in Florida on February 12, highlighting the complex logistics involved in processing critical evidence in high-profile cases.

For families of missing persons, such forensic dead ends represent devastating blows to hopes for resolution. The absence of database matches means investigators must now rely on other investigative methods, witness testimony, and the remaining DNA evidence still under analysis to advance the case.

As the investigation continues, the failed DNA match serves as a stark reminder of the limitations facing law enforcement, even when physical evidence appears promising. Without a match in criminal databases, the identity of the person who wore those gloves remains unknown, leaving more questions than answers in Nancy Guthrie's disappearance.
