The FBI is analysing a single unidentified strand of hair recovered from the bedroom of missing Arizona mum Nancy Guthrie, as experts warn that the digital and DNA work now at the heart of the 84‑year‑old's case in Pima County could take months, and potentially up to a year, to complete.
For context, Nancy Guthrie, mother of Today show co-host Savannah Guthrie, vanished from her Tucson-area home on 1 February. Blood later confirmed as Nancy's was found on the front porch, and investigators have treated the disappearance as a suspected abduction. More than 100 days on, there is still no confirmed sighting of the matriarch, no named suspect and, crucially, no clear forensic breakthrough that ties the scene to an offender.
