San Diego Tunnel Bust: What It Means for Immigration News 2026
A fake store near San Diego's busiest border crossing hid a secret tunnel stretching nearly two thousand feet into Mexico — and more than a ton of cocaine. Federal agents dismantled the operation and arrested four people. For immigrants living and working near the border, the fallout from major enforcement actions like this one can be felt far beyond the suspects themselves.
A Homeland Security task force has dismantled a sophisticated underground tunnel running nearly 1,933 feet from Tijuana, Mexico, to a fake retail store called "Buy 4 Less" near San Diego's Otay Mesa Port of Entry. Agents seized more than 1,000 kilograms — over 2,200 pounds — of cocaine valued at approximately $45 million. Four people now face federal charges connected to the operation.
How the Investigation Unfolded
Homeland Security Investigations (HSI) began watching the Buy 4 Less store in December 2025 after noticing suspicious activity: almost no real customers, and people carrying empty suitcases in and out. On May 29, 2026, agents watched suspects load heavy items into a van, transfer them into deep freezers, and move the freezers onto a truck. San Diego County Sheriff's deputies stopped the truck and, with help from a K9 unit, found evidence of controlled substances. A second truck and van linked to the operation also tested positive. Agents then executed search warrants at the store and a nearby mechanic shop, where they found the tunnel hidden under the store floor and accessible by a hydraulic lift. The tunnel had reinforced walls, a rail system, ventilation, and electricity.

Four people are charged with conspiracy to distribute controlled substances: Gregorio Epifanio Hernandez Lopez and Jose Jimenez of San Diego, and Brandon Escalante Sandoval and Antonio Cortez of Mexico. Hernandez Lopez faces additional charges for conspiracy to use a cross-border tunnel and conspiracy to import controlled substances. HSI San Diego acting Special Agent in Charge Kevin Murphy said the bust was "a significant blow to the Jalisco New Generation Cartel."
Why This Matters for Immigrants
Large drug enforcement operations like this one often lead to increased scrutiny at and around ports of entry, including Otay Mesa. Heightened law enforcement presence near border crossings can affect people with pending immigration cases, those waiting for green card applications, or anyone traveling in the area. Being near a law enforcement operation — even by coincidence — can raise questions. Knowing your rights during any ICE arrest or law enforcement encounter is important.
What to Do
- If you live or work near Otay Mesa or any active enforcement zone, carry your immigration documents (such as your green card, visa, or work permit known as an EAD — Employment Authorization Document) at all times.
- If law enforcement stops you, you have the right to remain silent. You do not have to answer questions about your immigration status without a lawyer present. Lawyers recommend saying: "I want to speak to an attorney."
- If you have a pending green card application, asylum application, or removal proceedings (a formal process where the government tries to deport you), contact your immigration lawyer immediately if you are detained or questioned.
- You can report suspicious activity related to drug smuggling by calling 866-DHS-2-ICE (866-347-2423) — doing so is voluntary and separate from your own immigration case.

Major drug enforcement operations near ports of entry often trigger broader immigration enforcement activity in the surrounding area, which can affect people with pending applications or removal proceedings — even those with no connection to the criminal case. If you are detained or questioned during or after an operation like this, do not answer questions about your immigration history without counsel present; anything you say can be used in immigration court. Anyone with an open immigration matter — whether a green card application, asylum case, or DACA renewal — should consult an immigration attorney before any law enforcement encounter escalates.
