MICHAEL WILLIAMS’ EVERY move was being tracked without his knowledge—even before the fire. In August, Williams, an associate of R&B star and alleged rapist R. Kelly, allegedly used explosives to destroy a potential witness’s car. When police arrested Williams, the evidence cited in a Justice Department affidavit was drawn largely from his smartphone and online behavior: text messages to the victim, cell phone records, and his search history.
The investigators served Google a “keyword warrant,” asking the company to provide information on any user who had searched for the victim’s address around the time of the arson. Police narrowed the search, identified Williams, then filed another search warrant for two Google accounts linked to him. They found other searches: the “detonation properties” of diesel fuel, a list of countries that do not have extradition agreements with the US, and YouTube videos of R. Kelly’s alleged victims speaking to the press. Williams has pleaded not guilty.
Data collected for one purpose can always be used for another. Search history data, for example, is collected to refine recommendation algorithms or build online profiles, not to catch criminals. Usually. Smart devices like speakers, TVs, and wearables keep such precise details of our lives that they’ve been used both as incriminating and exonerating evidence in murder cases. Speakers don’t have to overhear crimes or confessions to be useful to investigators. They keep time-stamped logs of all requests, alongside details of their location and identity. Investigators can access these logs and use them to verify a suspect’s whereabouts or even catch them in a lie.
