Customs and Border Protection officers at the Mariposa commercial facility seized 12,397 pounds of marijuana on Wednesday 11 March 2015 from a tractor-trailer whose load of varied pump components hid 534 bales of the drug inside cardboard boxes.[1][2] A narcotics detection canine had alerted officers to the rig, driven by Silvestre Tomas Camez-Mendoza, 39, of Nogales, Sonora, Mexico, and the CBP valued the load at nearly $6.2 million.[1][2]

It was the second co-mingled marijuana seizure in two days at the crossing: on Tuesday officers had found a nearly 2,500-pound load, 308 bundles hidden in green peppers, in a tractor-trailer driven by a 51-year-old Nogales, Sonora, man.[1][2] Together the two seizures totalled nearly 14,900 pounds worth nearly $7.4 million.[1]

The Wednesday seizure was the third-largest marijuana seizure at an Arizona port of entry, after 14,121 pounds in January 2013 and 20,375 pounds in November 2013.[2] Both drivers were arrested and referred to U.S. Immigration and Customs Enforcement’s Homeland Security Investigations.[1][2]
