Authorities are using advanced Bluetooth detection technology as part of the search Nancy Guthriewho has been missing for two weeks.
A Pima County Sheriff’s Department helicopter flies in a low, methodical grid pattern over the Tucson area, near Guthrie’s home, in an attempt to detect a signal from her pacemaker, according to Fox News. Researchers use specialized equipment that can identify nearby Bluetooth devices.
Guthrie was last seen on January 31 around 9:30 pm and was reported missing on February 1. According to reports, her pacemaker disconnected from its associated phone app shortly before 2 a.m. 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 agents typically operate at short range, meaning search crews must be nearby to pick up a signal.
The investigation is still ongoing.
