Nancy Guthrie has now been missing for more than 100 days after authorities say she was kidnapped from her Tucson, Arizona home back on February 1. Investigators believe the 84-year-old was taken against her will, and surveillance footage later showed a masked man tampering with her doorbell camera overnight before she disappeared. No suspects have been identified. Chris Nanos, the sheriff leading the investigation, says he is no longer personally communicating with Nancy’s family. Instead, contact is now handled through detectives and the FBI. Earlier in the case, Nanos had been texting and occasionally speaking directly with Savannah Guthrie, but says investigators are now handling all updates and communication.
