Police in Arizona are facing fresh scrutiny in the search for missing 84-year-old grandmother Nancy Guthrie, after internet sleuths highlighted a neighbour with a serious criminal past and an apparent link to the local sheriff through social media.
Guthrie vanished from her home in Pima County earlier this year, triggering an intensive search and a flurry of speculation because she is the mother of Today show host Savannah Guthrie. Detectives have publicly cleared all family members of suspicion, but with no confirmed breakthrough from forensic work or hundreds of hours of CCTV, a restless online true crime community has started hunting for its own answers.
