Fox News Digital learned authorities have used a high-tech Bluetooth scanner placed on the bottom of law enforcement helicopters to detect Nancy Guthrie’s pacemaker signal.
The helicopters fly low, typically in grid patterns, at a slow pace to pick up signals.
Fox News Digital spotted one of the low-flying helicopters near Guthrie’s home on Feb. 4, just three days after her disappearance.
