The Lawletter Vol 41 No 8
Mark Rieber, Senior Attorney, National Legal Research Group
In United States v. Lambis, No. 15CR734, 2016 WL 3870940 (S.D.N.Y. July 12, 2016), a federal court, apparently for the first time, suppressed evidence obtained as the result of the warrantless use of a cell-site simulator to locate a target's cell phone. The court explained that a cell-site simulator—sometimes referred to as a "StingRay," "Hailstorm," or "TriggerFish"—is a device that locates cell phones by mimicking the service provider's cell tower (or "cell-site") and forcing cell phones to transmit "pings" to the simulator. The device then calculates the strength of the "pings" until the target phone is pinpointed.
The court's holding relied mainly on Kyllo v. United States, 533 U.S. 27 (2001), which held that a Fourth Amendment search occurred when government agents used a thermal-imaging device to detect infrared radiation emanating from a home. In Kyllo, the Supreme Court reasoned that "[w]here . . . the Government uses a device that is not in general public use to explore details of the home that would previously have been unknowable without physical intrusion, the surveillance is a 'search' and is presumptively unreasonable without a search warrant." Id. at 40.
