Nancy Guthrie
Investigators Use Bluetooth Technology to Detect Pacemaker Signal
Published
Authorities are using advanced Bluetooth detection technology as part of the search for Nancy Guthrie, who has been missing for two weeks.
A Pima County Sheriff’s Department helicopter has been flying in a low, methodical grid pattern over the Tucson area near Guthrie’s home in an effort to detect a signal from her pacemaker, according to Fox News. Investigators are using specialized equipment capable of identifying nearby Bluetooth-enabled devices.
Guthrie was last seen around 9:30 PM on January 31 and was reported missing February 1. According to reports, her pacemaker disconnected from its companion phone app shortly before 2 AM on February 1. Around the same time, her Nest home security camera also went offline.
Former FBI special agent Maureen O’Connell told NewsNation that pacemaker-related detection tools typically operate at a short range, meaning search crews would need to be in close proximity to pick up a signal.
The investigation remains ongoing.
