Tucson, Arizona – Investigators searching for 84-year-old Nancy Guthrie have discovered DNA evidence at her home that does not belong to her or anyone in her immediate circle, according to Pima County Sheriff Chris Nanos. The revelation, announced Friday, marks a significant development in the case that began when Guthrie disappeared from her Tucson residence on January 30, 2026. The discovery of this unidentified DNA is fueling hopes for a breakthrough in the ongoing search for the missing woman, as authorities continue to piece together the events surrounding her disappearance.
The Pima County Sheriff’s Department confirmed the existence of the DNA in a press statement, stating that they are working to identify its source. The DNA was recovered from several gloves and other pieces of potential evidence found at the scene, Sheriff Nanos told ABC News. He expressed optimism that investigators are “getting closer” to solving the case, but declined to disclose the specific location where the DNA was found. The evidence is currently being analyzed by an out-of-state lab, a decision made in consultation with local FBI leadership to ensure consistent and streamlined testing.
Blood Evidence Suggests Struggle
The discovery of the unidentified DNA comes alongside earlier findings of blood at Guthrie’s home. Photos taken by Fox News Digital indicate blood droplets on the ground in front of her front door and in the driveway. Forensic pathologist Dr. Michael Baden, analyzing the patterns, suggested that Guthrie was bleeding from either her hands or face. “The nature of the blood spots with little pale centers or donut shapes are typical for drops that arrive from the nose or mouth, because they’re mixed with air,” Dr. Baden explained to Fox News Digital. He further stated that the droplets indicate she was either unable or did not attempt to stop the bleeding as she moved from the front of her house to the driveway, suggesting a possible abduction. Fox News Digital reported that Baden believes the blood dropped during an abduction, and “happened not in a normal, innocent way.”
Search Efforts and Reward
The search for Nancy Guthrie began after she was reported missing on January 30th. Law enforcement quickly focused on a vehicle seen in the area around the time of her disappearance, canvassing for a truck and reviewing Ring doorbell footage. The FBI released doorbell video showing an armed man near Guthrie’s home, and torn flowers were visible on the front porch. The FBI has since increased the reward for information leading to Guthrie’s return to $100,000.
Authorities have been tight-lipped about specific details of the investigation, citing the need to protect the integrity of the case. However, Sheriff Nanos has emphasized the department’s commitment to finding Guthrie and bringing those responsible for her disappearance to justice. The ongoing investigation involves collaboration between the Pima County Sheriff’s Department and the FBI.
What We Realize About the DNA
While the presence of unidentified DNA is a crucial development, many questions remain. Investigators are currently comparing the DNA samples to those of associates of Nancy Guthrie, according to Sheriff Nanos. The process of identifying the DNA’s owner could take time, as it involves extensive analysis and comparison to databases. The Sheriff’s Department has not released any information about the type of DNA found (e.g., nuclear, mitochondrial) or whether it is a full or partial profile. KGUN 9 News reported that investigators are not disclosing where the DNA was located.
Impact on the Investigation and Community Concerns
The discovery of DNA not belonging to Guthrie or her close contacts significantly broadens the scope of the investigation. It suggests the involvement of someone previously unknown to investigators, potentially indicating a targeted attack or a random act of violence. The news has understandably heightened anxiety within the Tucson community, particularly among elderly residents. Neighbors have expressed concern for Guthrie’s well-being and are cooperating with law enforcement by providing any information that might be helpful. The case has drawn significant media attention, raising awareness about the importance of community vigilance and reporting suspicious activity.
The investigation into Nancy Guthrie’s disappearance remains active and ongoing. Authorities are urging anyone with information about the case to contact the Pima County Sheriff’s Department or the FBI. The next update from law enforcement is expected following the completion of the DNA analysis. The Pima County Sheriff’s Department can be reached at (520) 329-7875. The FBI can be reached at (520) 248-8000.
