The U.S. District Court for the Southern District of New York ruled, in U.S. v. Lambis, that drugs seized from a defendant in a narcotics case were not admissible as evidence because the DEA agents had not obtained a warrant authorizing their use of a cell-site simulator (known as a “Stingray”) to track the location of the defendant’s phone and ultimately find the drugs. Notably, the Justice Department last year changed its internal policies to require federal agents to obtain a warrant before using a cell-site simulator, but the DEA’s use of the Stingray in this case preceded the policy change.
