\n Nearly six months after Nancy Guthrie disappeared from her home in the Catalina Foothills neighborhood of Tucson, Arizona, investigators released the full contents of a ransom note and a follow up investigators believe may contain clues that someone familiar with the alleged kidnappers may recognize.\n <\/p>\n
\n Law enforcement is urging the public to look at the linguistic patterns of the notes.\n <\/p>\n
\n Authorities said the messages feature \u201cdistinctive patterns of word choice, syntax, and phraseology\u201d that reflect the writer\u2019s unique style that people who knew them could recognize. The notes could also provide insight into the author\u2019s mindset, motives and how their tone changed over time \u2014 and provide a new lead that could help bring authorities closer to finding Guthrie.\n <\/p>\n
\n CNN has reached out to a Guthrie family spokesperson for comment on the release of the notes.\n <\/p>\n
\n The first note<\/a>, sent a day after her disappearance, came from someone who claimed they have her, and that \u201cshe is safe but scared\u201d and would not be released until payment, $4 million USD in bitcoin, is received, according to the full messages released by the Pima County Sheriff\u2019s Department <\/a>and the FBI Phoenix Field Office on Friday.\n <\/p>\n \n \u201cWe will be holding her for a maximum of 7 days,\u201d they wrote in the note addressed to NBC anchor Savannah Guthrie.\n <\/p>\n \n \u201cIf payment is not received by the last deadline on Monday the 9th at 5PM, she will be killed. Your mother is aware of this and her life is in your hands. It is in the best interest of everyone to have this completed as soon as possible. You will not be able to contact me from here on out, there will be no negotiation. Do not play games, law enforcement will not be able to help you.\u201d\n <\/p>\n \n The second note, sent on February 6, was directed to the \u201cGuthrie Family\u201d and claimed that Guthrie had died.\n <\/p>\n \n \u201cWe did not fully grasp the seriousness of her physical condition,\u201d the note read. \u201cWe never intended to hurt her, that was not our intention. She perished shortly after she was taken. We believe it was heart related. She is buried in nature now. Nothing you could have done could have changed the outcome. We want your family to know this and hope you all can find peace. We are truly sorry.\u201d\n <\/p>\n \n Investigators have continued to pursue forensic leads in the case, including DNA evidence, according to the Pima County Sheriff\u2019s Department. Hair found inside Guthrie\u2019s home has been tested but does not point to a suspect in the investigation into her abduction, the Pima County Sheriff\u2019s Department told CNN Thursday.\n <\/p>\n \n Investigators believe that someone who knows or has interacted with the writer of these notes \u2014 including a friend, family member, coworker, classmate or acquaintance \u2014 may recognize their writing patterns and have information that could help identify the person responsible.\n <\/p>\n
