Authorities say a fake retail store in San Diego served as a front for a cross-border tunnel used to move cocaine for the Jalisco New Generation cartel. The case led to four arrests, a major drug seizure, and the discovery of a sophisticated underground route.
Police found a secret underground hallway under a store that looked ordinary from the outside, like a hidden slide between two houses. They say people used it to move cocaine across the border, and that the hidden route was built with lights, air, and a cart track.
Analysis
What investigators say happened
Federal prosecutors charged four people, including two Mexican nationals and two Americans, with trafficking more than one ton of cocaine for the Jalisco New Generation cartel. The alleged operation centered on a San Diego business called Buy 4 Less, which investigators say was not functioning like a normal retail shop.
Homeland Security Investigations began watching the site in December after suspecting a tunnel beneath it. According to the criminal complaint, agents saw little customer activity but noticed people carrying suitcases in and out, sometimes taking them across the border into Mexico. On May 29, agents observed the suspects loading a truck with deep freezers and packages. After a traffic stop, drug-sniffing dogs alerted officers, and searches of other vehicles turned up more illicit drugs.
The tunnel
Authorities say the San Diego site concealed a tunnel that was about 55 feet deep and more than 1,000 feet long to the border, with officials suspecting it extended another 800 feet into Tijuana. The passage was reportedly about 4.5 feet tall and used a rail-and-cart system, along with electricity, ventilation, and a hydraulic lift for access.
The US attorney’s office said this was the first cross-border tunnel found in southern California since 2022. It also said authorities have discovered 99 such tunnels since 1993, with 28 classified as sophisticated. Officials described the seizure and tunnel discovery as a significant blow to the cartel.
Key points
- Four suspects were charged after authorities say they moved more than one ton of cocaine for the Jalisco New Generation cartel.
- Investigators say a San Diego business called Buy 4 Less hid a tunnel used for cross-border trafficking.
- Agents found a 55-foot-deep tunnel with a rail system, ventilation, electricity, and a hydraulic lift.
- Officials said the tunnel likely ran more than 1,000 feet to the border and may have extended into Tijuana.
- Authorities said it was the first cross-border tunnel discovered in southern California since 2022.
If the case holds up in court, the arrests and tunnel seizure could disrupt a major trafficking route and make it harder for this network to move drugs. The investigation also shows that coordinated local and federal surveillance can uncover even well-hidden border operations.
The tunnel’s size and equipment suggest that similar routes may still exist, even after this one was found. If the defendants are part of a larger network, the arrests may not end the flow of drugs and could simply push traffickers to build new concealments.
