Men would enter carrying suitcases that appeared empty, then leave carrying them full.
Beneath a storefront with no customers and suitcases that moved in empty and left full, federal agents in San Diego uncovered what organized crime has quietly perfected over decades: a tunnel as engineered as any legitimate infrastructure, burrowing 55 feet down and 1,000 feet toward the border. Four people now face the weight of potential life sentences, and a cartel's industrial artery has been severed — at least this one. It is the 99th such tunnel found since 1993, a number that speaks less to failure than to the relentless human capacity to build hidden worlds beneath the visible one.
- For months, a San Diego storefront called Buy 4 Less operated without a single real customer — only men with empty suitcases who left with them full.
- When agents finally moved in late May, a traffic stop yielded over 2,250 pounds of cocaine packed inside deep freezers loaded into waiting trucks.
- Four suspects aged 18 to 32, two American and two Mexican nationals, now face life sentences for running a Jalisco New Generation cartel pipeline beneath the border.
- The tunnel itself — 55 feet deep, hydraulically accessed, rail-equipped, ventilated, and stretching over 1,800 feet when counting its Tijuana extension — was no improvisation but an industrial feat.
- Authorities call it the first sophisticated cross-border tunnel found in southern California since 2022, and only the 28th of its kind in over three decades of discovery.
Federal agents first grew suspicious of a San Diego shop called Buy 4 Less near the Otay Mesa border crossing late last year. The store had no customers — only men arriving with empty suitcases and leaving with them full, sometimes walking them directly into Mexico. Homeland Security Investigations watched and waited.
By late May, they had seen enough. On the 29th, agents observed three vehicles loading deep freezers packed with packages into a truck. A traffic stop and drug-sniffing dogs confirmed what the surveillance had suggested: more than 2,250 pounds of cocaine. Four people were arrested — two Mexican nationals, two Americans, ranging in age from 18 to 32 — all charged with conspiring to traffic drugs on behalf of the Jalisco New Generation cartel. All face potential life sentences. One suspect faces an additional charge for constructing or financing the tunnel itself.
When agents entered the Buy 4 Less building, they found the operation's hidden heart: a tunnel descending 55 feet underground through a hydraulic lift, extending over 1,000 feet toward the border and believed to continue another 800 feet into Tijuana. Standing roughly 4.5 feet tall, the passage ran on a rail and cart system with electricity and ventilation — the infrastructure of industry, not desperation.
It is the first cross-border tunnel found in southern California since 2022, and only the 28th classified as sophisticated among the 99 discovered since 1993. The Buy 4 Less tunnel now joins that grim catalog — a reminder that the machinery of drug trafficking has grown as deliberate and complex as the commerce it mimics.
In December, federal agents began watching a shop called Buy 4 Less near the Otay Mesa border crossing in San Diego. The store had no customers. Men would enter carrying suitcases that appeared empty, then leave carrying them full. Sometimes they walked the cases across into Mexico. The agents suspected something was hidden beneath the storefront—something that didn't belong in a retail space.
By late May, Homeland Security Investigations had seen enough. On the 29th, they watched three vehicles pull up to the store. Men loaded deep freezers into a truck, filling them with packages. When San Diego County sheriffs stopped the truck on the road, drug-sniffing dogs alerted on the cargo. Officers searched the other two vehicles as well. In total, they confiscated more than 2,250 pounds of cocaine.
Four people were arrested. Two were Mexican nationals, two were American. Their ages ranged from 18 to 32. Federal prosecutors charged all of them with conspiring to traffic drugs for the Jalisco New Generation cartel across the US-Mexico border. All four face potential life sentences. One of them, Gregorio Epifanio Hernandez Lopez, also faces a separate charge for constructing, financing, or using an unauthorized tunnel.
When federal agents searched the Buy 4 Less building after the arrests, they found what the surveillance had suggested: a tunnel descending 55 feet underground, accessed by a sophisticated hydraulic lift. The passage extended more than 1,000 feet toward the border, and officials believe it continued another 800 feet into Tijuana on the Mexican side. The tunnel was roughly 4.5 feet tall, equipped with electricity and ventilation, and operated on a rail and cart system—the infrastructure of an industrial operation, not a hasty improvisation.
Kevin Murphy, the acting special agent in charge for Homeland Security Investigations in San Diego, called the discovery "a significant blow" to the cartel. The seizure of more than a ton of cocaine, combined with the dismantling of the tunnel itself, represented the kind of coordinated success that federal and local agencies rarely achieve against organized trafficking networks.
This was the first cross-border tunnel discovered in southern California since 2022. Since 1993, authorities have found 99 such tunnels along the US-Mexico border. Of those, 28 were classified as sophisticated—meaning they had the kind of engineering, ventilation, and operational infrastructure that this one possessed. The Buy 4 Less tunnel now joins that smaller category, a reminder that the infrastructure of drug trafficking has become as complex and engineered as legitimate commerce.

Why would a cartel go to such lengths—a 55-foot tunnel, hydraulic lifts, rail systems—when they could just move product through ports or hidden compartments?
Because those methods get caught. A tunnel is permanent infrastructure. Once built, it can move volume reliably, night after night. The cartel was thinking in terms of sustained, industrial-scale trafficking, not one-off shipments.
How long do you think this tunnel was actually operating before they got caught?
The complaint doesn't say. But the agents started watching in December and made the bust in May. That's five months of surveillance. The tunnel could have been running for years before that.
The store had no customers. Didn't that seem obvious?
It did to the agents. But a fake retail front only has to fool casual observers. The real operation happens at night, in the back, underground. The store's emptiness was actually the point—fewer witnesses, fewer complications.
What happens to the tunnel now?
It's dismantled. Filled in, destroyed. The infrastructure is gone. But the cartel will build another one somewhere else. This is a temporary setback for them, not a permanent solution.
Do you think the four people arrested will actually serve life sentences?
Possibly. Federal drug trafficking charges carry mandatory minimums, and conspiracy charges can stack. But plea deals happen. What matters more is that the tunnel is gone and the supply line is disrupted—at least for now.
