So investigators tried a new trick: they called Google. In an affidavit filed on February 8th, nearly a year after the initial robbery, the FBI requested location data pulled from Graham’s Samsung Galaxy G5. Investigators had already gone to Graham’s wireless carrier, AT&T, but Google’s data was more precise, potentially placing Graham inside the bank at the time the robbery was taking place. “Based on my training and experience and in consultation with other agents,” an investigator wrote, “I believe it is likely that Google can provide me with GPS data, cell site information and Wi-fi access points for Graham’s phone.”
That data is collected as the result of a little-known feature in Google Maps that builds a comprehensive history of where a user has been — information that’s proved valuable to police and advertisers alike. A Verge investigation found affidavits from two different cases from the last four months in which police have obtained court orders for Google’s location data. (Both are embedded below.) Additional orders may have been filed under seal or through less transparent channels.
