The tunnel, which was shut down Wednesday night after several weeks of surveillance, took about a year to build, the authorities said Thursday. Three people were taken into custody, and federal agents seized eight tons of marijuana and 325 pounds, or 147 kilograms, of cocaine they said was connected to the investigation. As security at the border - both at the ports of entry and between them - has heightened in recent years, drug cartels have increasingly sought other avenues to move drugs into the United States. This was the fifth large-scale drug smuggling tunnel discovered in the San Diego area since 2010, the authorities said, and the eighth since 2006, when the Sinaloa drug cartel took control of the smuggling corridor along this section of the border. "These cartels have spent years and tens of millions of dollars trying to create a secret underworld of passages so they can move large quantities of drugs," said Laura Duffy, the United States attorney for the San Diego region. Derek Benner, special agent in charge for Homeland Security Department investigations in San Diego, said sophisticated tunnels like the one found here - which required not only laborers to build but also architects and engineers, and could have cost over $1 million to construct - were an investment only a well-financed cartel could afford to make. He said the tunnel - like the two most recent "super tunnels" in the region, which were discovered in late 2011 - was shut down before any narcotics reached the market in the United States, which he called a major blow to the cartel. "They're desperate," said William R. Sherman, special agent in charge for the Drug Enforcement Administration in San Diego. "We're starting to see them try to move cocaine through these tunnels, which we've never seen before. We're seeing them try to move cocaine through ultra-lights into the desert, which we've never seen before. And those are simply acts of desperation." - --- MAP posted-by: Jay Bergstrom
