How the Nancy Guthrie probe unfolded: 5 key developments from mysterious abduction to death note

The mystery surrounding Nancy Guthrie's disappearance began on February 1, when her family reported her missing after they were unable to contact her and discovered she had not attended church as expected. The last confirmed sighting of Guthrie was at approximately 9.48 p.m. on January 31, when her son-in-law, Tommaso Cioni, dropped her off at her Tucson home after dinner at her daughter Annie's residence. As the Sheriff's Office began investigating the disappearance, it was revealed that the doorbell camera at her home disconnected at 1.47 a.m., and software detected someone or possibly an animal on a camera about 25 minutes later. Guthrie's pacemaker app showed it disconnected from her phone at 2.28 a.m.

After the initial investigation, Pima County Sheriff Chris Nanos stated that he believes Nancy was abducted, confirmed her disappearance was being treated as a crime, and urged neighbors to review their home video camera footage. However, troubling questions arose when several media outlets, including TMZ and CNN affiliates KGUN and KOLD, received the first purported ransom letters demanding millions of dollars in bitcoin for her return. One note set a first deadline of 5 p.m. Thursday, February 5, and a second deadline for February 9. Investigators at the time confirmed they were analyzing the ransom notes but refrained from disclosing their contents. Around the same time, it was revealed that investigators were also examining what appeared to be drops of blood outside the front door. A law enforcement source told CBS News that some blood was also found inside the house. Later, the blood was confirmed to be hers.

As investigators continued to work on the case without a suspect or person of interest, Savannah Guthrie released an emotional video pleading for her mother's return and saying her family is 'ready to talk.' 'We live in a world where voices and images are easily manipulated. We need to know without a doubt that she is alive and that you have her,' Savannah Guthrie said in the video with her two siblings, addressing a possible captor or captors. The Today show host pleaded that her mother's health and heart are fragile. 'She lives in constant pain. She is without any medicine. She needs it to survive. She needs it not to suffer,' she added. Around that time, Trump revealed he had spoken with Savannah Guthrie and pledged that 'ALL Federal Law Enforcement' resources would be available to assist the family and local investigators.

On February 10, the FBI, led by Kash Patel, and the Pima County Sheriff's Department in Arizona released surveillance images and video related to Nancy Guthrie's disappearance. The footage shows a masked person wearing a backpack and gloves at her door, appearing to tamper with the camera while armed on the morning Guthrie went missing. Based on evidence from the footage, investigators detained a deliveryman, but he was released soon after authorities conducted a court-authorized search of his Rio Rico, Arizona, home. He told reporters, 'I hope they get the suspect, because I'm not it.' The FBI later released a more detailed description of the individual seen in the doorbell-camera footage, describing the suspect as approximately 5-foot-9 to 5-foot-10 with an average build. Investigators also identified the backpack the person was believed to be carrying as a black 25-liter Ozark Trail Hiker Pack and doubled the reward for information in the case to $100,000.

The case took a chilling turn when reports surfaced of a ransom note allegedly claiming that Nancy had been accidentally killed. According to the communication, the sender expressed regret over her death but continued to demand money. This revelation sparked renewed debate about what really happened to Nancy and whether the note was a genuine breakthrough or another misleading clue. Months after her disappearance, the mystery remains unsolved, leaving investigators and her family still searching for answers.
