Fresh clues surface as FBI returns to Nancy Guthrie disappearance in Tucson

Federal agents returned to Nancy Guthrie’s Tucson neighborhood more than a month after the Arizona grandmother vanished, with detectives reviewing evidence—including doorbell footage and cellphone/purchase data—as a neighbor’s Ring clip is examined and a reward of up to $1 million is offered by Guthrie’s daughter Savannah. No suspects have been named, and officials say the case remains active.
