Federal authorities have dismantled a highly sophisticated cross-border drug smuggling tunnel connecting Tijuana, Mexico, to a retail store in San Diego, California, leading to the seizure of approximately $45 million worth of cocaine and the arrest of four individuals. The discovery, announced by federal prosecutors, marks a significant blow to drug trafficking operations in the region and highlights the elaborate methods employed by cartels.
The subterranean passageway, estimated to be nearly 2,000 feet long, was found 55 feet deep and 4.5 feet high, equipped with reinforced walls, electricity, ventilation, and a rail system for transporting narcotics. Its exit point in the U.S. was concealed beneath the floor of a storage room within a "Buy 4 Less" store near the Otay Mesa Port of Entry in San Diego. Access to the tunnel from the store side was facilitated by a hydraulic lift.
The investigation, conducted by a Homeland Security Task Force, spanned several months, beginning in December 2025. Agents reportedly surveilled the "Buy 4 Less" store after observing suspicious activity, including minimal customer foot traffic and individuals frequently entering and exiting with empty suitcases, which did not align with a typical retail operation. This surveillance ultimately led to the uncovering of the illicit network.
On May 29, 2026, law enforcement intercepted three vehicles attempting to transport cocaine, resulting in the seizure of over 2,270 pounds (more than a ton) of the drug. Following these interdictions, federal agents searched the "Buy 4 Less" store, where they located the tunnel's concealed exit.
Four individuals have been arrested in connection with the operation: Gregorio Epifanio Hernandez Lopez, 29, Jose Jimenez, 32, Antonio Cortez, 18, and Brandon Escalante Sandoval, 26. All face charges of conspiracy to distribute controlled substances, with Hernandez Lopez also charged with conspiracy to use a cross-border tunnel and conspiracy to import controlled substances. Each defendant faces a maximum penalty of life in prison and a $10 million fine.
U.S. Attorney Adam Gordon commented on the bust, stating, > "They thought they saw the light at the end of the tunnel. In fact, what they saw were our lights and sirens." Authorities have linked the operation to the Jalisco New Generation Cartel (CJNG), emphasizing the impact of this seizure on the cartel's activities. This sophisticated tunnel is one of 99 discovered in the Southern District of California since 1993, with 28 of them deemed highly advanced.
