Nancy Guthrie, an 84-year-old woman missing since January 31 from her home in Arizona, is the target of cruel blackmailers who claim to know her whereabouts but are demanding over £50,000 (approximately $63,000 USD) in Bitcoin for information. The blackmailers allege that Nancy is already 'dead' and have sent multiple letters to her family, particularly targeting her daughter, Savannah Guthrie, a host on NBC's Today show. Harvey Levin, founder of the American news outlet TMZ, revealed that the latest letter demands a cryptocurrency transfer in exchange for details about Nancy's body and the alleged kidnapper. The blackmailer expressed frustration at being dismissed as a scam, despite claiming they have been willing to provide information since February 11. Investigators are treating these letters with skepticism, as there is no evidence that the sender has any legitimate knowledge about Nancy's situation. Footage from a doorbell camera shows a masked figure, but this individual has not been identified. Savannah Guthrie has publicly appealed for tips, offering cash rewards for information that could lead to her mother's return.
