Federal authorities have uncovered one of the most sophisticated cross-border tunnels in recent years, hidden beneath a retail store in San Diego. The passage, which ran 1,933 feet at a depth of 55 feet, linked Tijuana directly to a commercial strip near the Otay Mesa Port of Entry. Inside, agents found reinforced walls, electricity, ventilation, and even a rail system—a level of engineering that signals a major investment by organized crime.
The discovery came after a Homeland Security investigation launched on May 29, 2026. Agents seized more than a ton of cocaine valued at $45 million inside Buy 4 Less, a business at 2498 Roll Drive, Suite E. The tunnel stood just 4.5 feet tall, forcing anyone moving through it to crouch, but its construction was anything but crude.
Charges against the alleged engineer
Federal prosecutors have charged Luis Manuel Hernandez Victoria, known as “El Ingeniero,” with designing the tunnel for the Jalisco New Generation Cartel (CJNG). He was arrested in Jalisco state on October 15, 2026, during a coordinated raid with Mexican authorities, who also seized firearms and narcotics. A federal grand jury has indicted him on charges of providing material support to a foreign terrorist organization and conspiracy to construct or finance a cross-border tunnel.
This prosecution marks the seventh individual charged in connection with the underground network, which came under heightened scrutiny after CJNG received its official foreign terrorist designation on February 20, 2025. U.S. Attorney Adam Gordon said in a statement that “Hernandez engineered his own downfall,” while reminding the public that charges remain allegations until proven in court.
The tunnel’s sophistication has drawn comparisons to the most advanced smuggling routes ever found along the U.S.-Mexico border. Its location—directly beneath a store—allowed traffickers to move shipments with relative ease, blending into the daily flow of commerce in a busy border zone.
Broader crackdown on underground routes
The San Diego tunnel is not an isolated case. In the Nueva Tijuana neighborhood, Mexican naval forces and federal officers discovered a second underground route measuring 869 feet, lined with wood at a depth of 21 feet. That operation turned up ammunition, mobile phones, bank cards, a digital video recorder, and dozens of doses of methamphetamine, according to officials.
These discoveries highlight the ongoing challenge of detecting tunnels that are often built with advanced engineering and hidden beneath legitimate businesses. For border security task forces, identifying active tunnels remains a primary strategic goal, and multi-agency operations continue to expand across southern California.
The alleged $45 million smuggling operation reflects a sustained push by federal prosecutors to dismantle the supply lines of foreign terrorist organizations operating along the border. Law enforcement teams are actively working to identify all remaining co-conspirators involved in financing and operating these subterranean passages.
For Latino communities on both sides of the border, the news is a reminder of the complex realities of cross-border life. While the tunnel represents a criminal enterprise, it also underscores the resilience of law enforcement in disrupting operations that threaten public safety. As investigations continue, authorities urge anyone with information to come forward.
This case also resonates with broader concerns about border security and the impact of cartel activity on everyday communities. From California's Halloween hotspots to the vanishing coastline, the state faces a range of challenges, but the fight against cross-border smuggling remains a top priority.
As the legal process unfolds, the case against Hernandez Victoria will be closely watched. It also highlights the importance of international cooperation, as U.S. and Mexican authorities worked together to bring the alleged engineer to justice. The tunnel may be sealed, but the investigation is far from over.
