Police release 2 notes in 6-month search for Nancy Guthrie
What's new: Investigators hope the notes' wording, Bitcoin demand and Tucson references trigger fresh leads in Arizona.
Arizona investigators released two ransom notes tied to the disappearance of Nancy Guthrie, who vanished from her Tucson-area home six months ago at age 84, hoping the documents will help identify whoever took her. One note demanded millions of dollars in Bitcoin and threatened to kill her if payment was not made by a stated deadline. A second note claimed she died soon after the abduction and was buried outdoors. Pima County Sheriff Chris Nanos said the notes contain distinctive language that someone may recognize. Outside experts cited shifts in pronouns, spelling errors and references to technology as possible clues, while also warning the letters could be fake and may have been written to mislead investigators.
