Nogales, Arizona - U.S. Customs and Border Protection officers at Arizona’s Port of Nogales apprehended a Tucson woman involved in a failed attempt to smuggle more than 4 pounds of methamphetamine and heroin into the United States this week.

Officers working at the Dennis DeConcini Crossing referred a 21-year-old Tucson woman for further inspection of her Ford sedan Wednesday night.
