FBI Warns About Deepfakes Hampering Kidnapping Proof

The FBI and local investigators warned Thursday that advances in AI enable realistic deepfakes, complicating "proof of life" in the disappearance of 84-year-old Nancy Guthrie from Tucson last weekend. Authorities say they have not received confirmed deepfake images of Guthrie but have received purported ransom notes and are treating them seriously; they urged digital forensics, verification and provided consultation to the family while the search continues.
