Eighty four year old Nancy Guthrie vanished 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 suddenly 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 found on the porch. Her pacemaker stopped transmitting shortly after.

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

Nancy Guthrie remains missing. Authorities continue to investigate, and the FBI is urging anyone with information to come forward.
