Hair Test In Nancy Guthrie Kidnapping Case Comes Back Inconclusive

Sheriff Chris Nanos said a hair sample collected at Nancy Guthrie's Tucson home tested inconclusive and "came back with no results" on Thursday, July 30, 2026.[1]

Pima County officials said the finding had been verified in early June but was not publicly shared until Nanos discussed it this week.[1] Authorities said blood and other DNA at the scene have so far yielded no matches, and samples are being examined by multiple labs, including the FBI crime lab in Quantico.[1]

Nancy Guthrie, 84, was last seen the evening of January 31, 2026, and security video shows a suspect at her door early February 1.[1] Investigators have treated the disappearance as a likely abduction after ransom notes were left at Guthrie's home.[1]

Nanos said the case remains active and is not considered cold, and he publicly addressed and downplayed earlier criticism from FBI Director Kash Patel about the timing of federal involvement.[1]
