Customs agents working at the commercial port in Nogales seized about $1.4 million worth of illegal drugs from a tractor-trailer rig crossing the border this weekend. The seizure was the third largest by Customs and Border Proctection at an Arizona port of entry, the agency said. On Saturday, July 7, 2018, the driver of a tractor-trailer rig was sent to a secondary inspection at the Mariposa Commercial Facility. A drug dog alerted to the trailer and agents discovered nearly 364 pounds of meth worth $1,092,000; six pounds of heroin worth about $100,000; seven pounds of fentanyl worth about $96,000; and about 6,000 pills suspected to be oxycodone, worth about $113,000. The drugs and tractor-trailer rig were seized. The driver, a 65-year-old man, was arrested.
