Half a Ton of Cocaine Found Under Trailer Floorboards at Calexico Port of Entry

Federal officers at California's Calexico Port of Entry pulled more than 1,000 pounds of cocaine out from under the floorboards of a commercial truck's flatbed trailer, according to the U.S. Attorney's Office for the Southern District of California. The drugs were stashed beneath 269 bundles of rebar. Authorities put the street value at over $20 million.

The driver, Jose Manuel Lopez Lopez, 44, was the only person in the truck when he crossed from Mexicali, Mexico, prosecutors said. Customs and Border Protection officers ran the flatbed through an X-ray and spotted anomalies in the wooden floorboards. A drug-sniffing dog alerted on the trailer shortly after.

Officers unloaded the rebar, unscrewed the planks, and found 366 packages crammed underneath. The total haul weighed 1,002.13 pounds, or 454.56 kilograms, according to FreightWaves and TheTrucker.com, both of which cited the same U.S. Attorney's Office release. Homeland Security Investigations and the Drug Enforcement Administration assisted CBP in the case.

Prosecutors didn't undersell the size of the bust. In their motion to detain Lopez, they called it "a tremendous amount of drugs, even by the standards of this district," a district that runs some of the busiest drug-interdiction operations on the southern border.

This is the second-largest cocaine seizure in the Southern District of California so far in 2026. The largest came in May, when a task force investigation into a supposed retail business near Otay Mesa led agents to a 1,933-foot cross-border tunnel running from Tijuana, reportedly reaching 55 feet deep with reinforced walls, rail tracks, ventilation and electricity. That case, tied to a Buy 4 Less store with a hydraulic lift concealing the tunnel entrance, produced more than 2,269 pounds of suspected cocaine worth an estimated $45 million and led to charges against four people, per the U.S. Attorney's Office.

Lopez pleaded not guilty at his federal arraignment on July 28. U.S. Magistrate Judge Lupe Rodriguez Jr. set a detention hearing for August 3. Assistant U.S. Attorneys Paul Benjamin and Lawrence Casper are handling the prosecution under case number 26-mj-08705.

Lopez is charged with importing cocaine into the United States under Title 21 of the U.S. Code, Sections 952 and 960. That charge carries a mandatory minimum of 10 years in prison and a maximum of life. He is presumed innocent unless and until proven guilty in court. The case is being prosecuted through the California Homeland Security Task Force as part of Operation Take Back America.

Nobody in these reports claims Lopez knew the drugs were there. England Logistics, a freight-industry outlet, raised a point that can be overlooked in the headline numbers: drivers with clean records and reputations for honesty are sometimes deliberately targeted by traffickers precisely because they're less likely to draw suspicion, a practice the industry calls using "blind mules." Whether that applies here isn't established by any court filing in these sources. Prosecutors haven't alleged one way or the other in the material available.

England Logistics also flagged a broader pattern that's harder to dismiss. FreightWaves reported over $51.4 million in drugs and counterfeit goods tied to the trucking industry seized in April alone, with contraband hidden in produce loads, construction materials and trailers. High cross-border truck volume makes it easy for a compromised load to look identical to a legitimate one, and full inspections requiring X-rays and K9 units can't be run on every truck that crosses.

The rebar-and-cocaine method used at Calexico isn't new, but it's effective precisely because it exploits inspection limits. CBP's screening caught this one. The open question is how many similar loads don't get flagged, and how that gap gets closed without grinding legitimate freight to a halt at the border. Lopez's detention hearing was set for August 3; the outcome of that hearing was not detailed in the available reporting. How prosecutors build an importation case against a driver who says he didn't know what he was carrying remains the central question as the case moves forward.
