The investigation has also leveraged the frontiers of modern forensic technology, moving beyond physical clues to analyze the “digital ghost” left behind by Nancy’s medical devices. In a harrowing revelation, investigators disclosed that Nancy’s pacemaker provided a precise timestamp for the disruption. The device’s data logs showed an unexplained spike followed by a cessation of normal communication at approximately 2:00 a.m. on February 1. This technological footprint suggests that the elderly woman was likely confronted and removed from her home under the cover of total darkness, nearly four hours after the time Cioni reported seeing her safely inside. This gap in time is now the primary focus of the Pima County Sheriff’s Department and federal agents, who are working to determine who had access to the property during those critical early morning hours.
