Pima County Sheriff Chris Nanos said investigators are still working through substantial amounts of forensic and video evidence gathered since Guthrie's disappearance. "We have so much in terms of video evidence to look at. The FBI has said it is investigating the case as a kidnapping for ransom, and the bureau reiterated in a recent statement on X that the case continues to be treated that way. The investigation took an unusual turn in June, when NBC News reported that a second note had been sent to media outlets indicating Nancy Guthrie had died. Despite that development, authorities have not confirmed Nancy Guthrie's death, and the case remains classified as an active kidnapping investigation.
