Officers from U.S. Customs and Border Protection’s Office of Field Operations at the Port of Nogales’ Mariposa crossing referred 70-year-old Mexican national Jose Enriquez-Anzar for a non-intrusive inspection of the tractor-trailer he was driving on Monday 17 November 2014, after an x-ray showed an anomaly inside the supposedly empty trailer.[1][2] A narcotics detection canine then alerted to drugs, and officers found 139 bundles of marijuana weighing 2,946 pounds behind a false wall, which the agency valued at $1,473,000.[1][2]

Officers seized the drugs and the tractor-trailer, and turned Enriquez-Anzar over to U.S. Immigration and Customs Enforcement’s Homeland Security Investigations.[1][2]
