CINCINNATI - A Sixth Circuit U.S. Court of Appeals panel on Aug. 14 upheld a man's drug-trafficking and money-laundering conviction, finding that U.S. Drug Enforcement Agency agents' use of GPS data that the defendant's cell phone emitted did not violate his rights under the Fourth Amendment to the United States Constitution, U.S.C.S. Const. Amend. 4. (United States of America v. Melvin Skinner, No. 09-6497, 6th Cir.; 2012 U.S. App. LEXIS 16920).
