Federal agents discovered two more major drug tunnels between California and Mexico this week, reports USA Today. Each began under a warehouse in Tijuana and ended under another in San Diego. The discovery holds a lesson for cartels: If you're going to spend millions building these things, you might want to invest in better fronts. Immigration and Customs Enforcement agents found the first one after noting that the US warehouse had nothing but cheap toys inside, as if it were an exporter, the same front used in a tunnel found last year, reports the Union-Tribune.
The discovery of the first tunnel led to the discovery of the second one in a nearby warehouse in the same industrial park. Authorities arrested a 73-year-old woman in Chula Vista, California, suspected of supervising the smuggling operations, reports the LA Times. The tunnels were 600 to 700 yards long and were equipped with lighting and rail systems, with one notably more sophisticated than the other. Unlike previous discoveries—these are the sixth and seventh tunnels found between Tijuana and San Diego since 2010—no drugs were found during the raids. (More Mexico stories.)
