The disappearance of 84-year-old Nancy Guthrie has shifted from a routine missing person report to what authorities describe as a deeply concerning investigation. Officials say new evidence suggests the situation may involve foul play.

Investigators revealed that Nancy’s pacemaker suddenly stopped syncing with her Apple Watch at about 2 a.m. Sunday. Authorities believe this means she was no longer within Bluetooth range of the device. Her Apple Watch was later found inside her home, raising fears she did not leave willingly. Officials are now analyzing the device timeline to reconstruct what happened during those early morning hours.

Nancy was last seen Saturday around 9:45 p.m., and concern grew when she missed church the next morning — something family members described as unusual. When officers entered the residence, they reported “indications of forced entry” and confirmed the “presence of blood inside the residence.” While details about the blood remain undisclosed, authorities acknowledged the findings suggest “the possibility of foul play.”

Sheriff Chris Nanos stressed that Nancy depends on daily medication, warning her health could quickly worsen without it. Law enforcement is prioritizing the case due to both her age and medical needs.

Former FBI agent Nicole Parker stated the situation appears inconsistent with a random crime, suggesting possible involvement by someone familiar with Nancy or her routine. Investigators are treating the home as a central crime scene and continue examining forensic evidence. Officials are withholding some details to protect the investigation while urging anyone with information to come forward.
