The story
On May 20, 2019, an armed robber entered the Call Federal Credit Union in Midlothian, a suburb south of Richmond in Chesterfield County, handed a teller a note demanding cash, and fled with approximately $195,000. Despite witness interviews and surveillance footage, the robber escaped and remained unidentified. Police had little to go on: witnesses saw the suspect approach from an adjacent church while apparently on a cell phone, but that was insufficient to identify him.
On June 14, 2019, Detective Joshua Hylton of the Chesterfield County Police Department applied to a Virginia magistrate for a geofence warrant directed at Google. A geofence warrant draws a virtual perimeter around the crime location and a specific timeframe, then requires the tech company to search its database for all devices that entered that zone. In this case, officers drew a circle with a 150-meter radius around the credit union. Google's Location History service records phone locations approximately every two minutes, and the company produced anonymized data for all users present during the relevant window. Police then narrowed the results and requested that Google unmask certain identities, revealing Okello Chatrie's personal information. His location data showed he entered the geofence roughly ten minutes before the robbery and headed toward a residential area immediately after. He was arrested, prosecuted, and convicted.
Chatrie appealed on Fourth Amendment grounds, arguing that police had conducted a "search" when they accessed his location data without demonstrating particularized suspicion. The case reached the U.S. Supreme Court at a moment when geofence warrants had become ubiquitous: Google received its first such warrant in 2016, 982 by 2018, and over 11,000 by 2020. Tens of thousands of criminal investigations nationwide now rely on the technique, touching hundreds of millions of smartphone users whose location data resides in Google's systems.
On June 29, 2026, in a 6-3 decision led by Justice Elena Kagan and joined by Chief Justice John Roberts and Justices Sonia Sotomayor, Brett Kavanaugh, and Ketanji Brown Jackson, the Supreme Court held that police conducted a Fourth Amendment search when they obtained Chatrie's location information. Justice Kagan wrote that "an individual has a reasonable expectation of privacy in records about his cell phone's location, and police intrude on that constitutionally protected interest when they demand the information." The Court did not strike down geofence warrants entirely, but instead ruled that they trigger full Fourth Amendment scrutiny, meaning officers must now meet stricter standards when seeking them. The justices remanded the case to the 4th U.S. Circuit Court of Appeals to determine whether the specific geofence warrant in Chatrie's case was "reasonable" under the Fourth Amendment and whether each step of the three-stage search process complied with constitutional requirements.

The case for
Law enforcement argues that geofence warrants are an essential modern investigative tool that allows police to solve serious crimes when traditional methods fail. In cases like Chatrie's, the technique narrowed an enormous pool of potential suspects to a manageable few, enabling officers to identify a suspect who might otherwise have escaped justice. Police contend that the warrants do not differ fundamentally from other investigative techniques like subpoenas for bank records or phone toll records, and that proper judicial oversight, requiring a warrant application to a magistrate or judge, already provides safeguards. Restricting geofence warrants could hamper investigations into armed robbery, terrorism, sexual assault, and other violent crimes, particularly in cases where surveillance footage is unavailable or unreliable.
The case against
Privacy advocates and civil liberties organizations argue that geofence warrants represent a troubling form of mass surveillance that sweeps up location data on thousands of innocent bystanders simply to identify one suspect. The technique inverts traditional investigation by targeting an area rather than a person, exposing millions of people to data collection despite having no connection to any crime. Location data reveals intimate details about individuals' lives: where they worship, whom they visit, where they receive medical care, and their daily patterns. Before the Supreme Court's decision, many magistrates approved geofence warrants with minimal scrutiny, sometimes without fully understanding the scope of the search. Critics worry that even with the new Fourth Amendment framework, judges may continue to approve these warrants too readily, especially in serious felonies. The ruling acknowledges that privacy interests extend to digital information held by third parties, a principle with far-reaching implications for how police use tech company databases.
Why it matters: The Supreme Court decision directly affects how police investigate crimes in Chesterfield County and throughout Virginia and the nation. Residents now have explicit constitutional protection against police accessing their location data without meeting heightened Fourth Amendment standards, though the practical impact depends on how lower courts apply the ruling to future cases. The decision also signals the Supreme Court's willingness to extend Fourth Amendment protections to digital information held by tech companies, potentially influencing how police use other forms of data collection in investigations.
