Eighty four year old Nancy Guthrie disappeared from her Catalina Foothills home in Tucson after returning from dinner with her daughter on January 31.

At 1:47 a.m., her doorbell camera abruptly disconnected. Newly released FBI footage shows a masked and armed individual approaching the front door, attempting to block the camera, and then ripping it off. Blood matching Nancy’s DNA was later found on the porch. Her pacemaker stopped transmitting shortly afterward.

In the days that followed, multiple ransom notes demanding Bitcoin were sent to media outlets. No proof of life has been provided. Investigators have canvassed surrounding neighborhoods, interviewed persons of interest, and recovered a black glove believed to be connected to the scene.

Nancy Guthrie remains missing. The FBI continues to investigate and is asking anyone with information to come forward.
