“I’m sure if we want to keep these cartels to smuggle drugs groped in the United States in this way, we’re going to find them, and we’re going to find them faster than they can build,” said William R. Sherman, who acts as a special agent in charge of the Drug Enforcement Administration in San Diego.

Highway troopers found three tons of marijuana packed in boxes inside the Cargo Truck stopped after it departed from San Diego warehouse.
