The Pima County Sheriff's Department in Arizona released two ransom notes Friday that were tied to Nancy Guthrie's disappearance, six months after she disappeared. Guthrie, the 84-year-old mother of "Today" show co-host Savannah Guthrie, has been missing since February and is believed to have been kidnapped. The notes include redactions and the sheriff's department said it hopes that people will be able to help identify the writer and alleged kidnapper by the writer's style and voice. The second note also included an apology that emphasized there was nothing the family could have done to save her. "We received your message and we understand," Savannah Guthrie said after receiving the second note.
