Rare DNA Testing Yields No Leads in Nancy Guthrie Disappearance

The investigation into the disappearance of 84-year-old Nancy Guthrie has entered its seventh month without identifying a suspect, despite recent rare DNA testing on hair found at her home. Pima County Sheriff Chris Nanos confirmed that the test results offered no leads, a disappointing outcome as investigators had hoped for a breakthrough. The FBI's Phoenix field office corroborated these findings but offered no further comment, emphasizing that the case remains under active investigation.

Investigators continue to analyze other forensic evidence recovered from Nancy Guthrie's residence, which includes mixed DNA samples from at least four individuals. This complex genetic material is currently being examined by multiple forensic laboratories across the United States, including the FBI laboratory in Quantico, Virginia. Authorities caution that full analysis of the mixed DNA is not guaranteed and may not lead to identifying anyone connected to the case.

Nancy Guthrie vanished from her home on February 1, 2026, under suspicious circumstances. A doorbell camera reportedly captured a masked man with a backpack outside her home hours before her disappearance, with another masked individual also seen nearby. Despite these sightings, no suspects have been publicly identified. In response to the prolonged lack of progress, Savannah Guthrie has made an emotional appeal, urging anyone with information to come forward and help find her mother. The Guthrie family is offering a USD 1 million reward, and the FBI has added a USD 100,000 reward for information leading to Nancy's safe return.
