According to journalist Marcy Wheeler, the FBI relied heavily on controversial geofence warrants as part of its investigations into January 6 suspects, identifying over 5,000 unique devices based on Google Location History. Geofence search warrants are meant to locate devices within a given area based on digital services like GPS, Bluetooth, or Wi-Fi signals.

Further, it appears that individuals who attempted to delete their location data in the days after January 6 were of particular interest to the FBI.
