United States Drug Enforcement Administration: San Luis, Ariz.

San Luis Dept: PHOENIX - Two drug-smuggling tunnels outfitted with lighting and ventilation systems were discovered along the U.S.-Mexico border, the latest signs that cartels are building sophisticated passages to escape heightened surveillance on land, according to Winnipeg Free Press. The other was completed and discovered Saturday in a vacant strip mall storefront in the southwestern Arizona city of San Luis. It showed a level of sophistication not typically associated with other crude smuggling passageways that tie into storm drains in the state and in this undated photo provided by the United States Drug Enforcement Administration, shows floor shaft entrance from a storage room that was a 240-yard, a complete and fully operational drug smuggling tunnel that ran from a small business in Arizona to an ice plant on the Mexico side of the border, Thursday, July 12, 2012, in San Luis, Ariz.

One began under a bathroom sink inside a warehouse in Tijuana but was unfinished and didn't cross the border into San Diego. The Mexican army found the tunnel Wednesday. (www.immigrantscanada.com).
