Truck’s Fuel Tank Concealed $1 Million Worth of Meth, Authorities Say
962 Pounds of Liquid Methamphetamine Found in Bobtail Truck’s Fuel Tank on I-15
U.S. Border Patrol agents seized 962 pounds of liquid methamphetamine—approximately 115 gallons—with an estimated street value of $1 million during a traffic stop on Interstate 15 in Temecula, California.
The seizure occurred at about 11 a.m. Sept. 29, 2026, when agents assigned to the Border Patrol’s San Diego Sector stopped a northbound semi-truck traveling without a trailer. The vehicle was stopped approximately a quarter mile north of the California Highway Patrol scales, according to U.S. Customs and Border Protection.
During the stop, a Border Patrol agent and a K-9 partner identified indications that liquid methamphetamine could be concealed in at least one of the truck’s fuel tanks. The vehicle was a bobtail tractor, meaning it was operating without a trailer.
After the discovery, agents transported the truck and its driver to the Newton-Azrak Border Patrol Station in Murrieta for further processing. Hazardous-response specialists were brought in to safely remove the liquid contents from the fuel tank.
The recovered substance tested positive for methamphetamine. Authorities said the total amount weighed 962 pounds, equivalent to about 115 gallons, and had an estimated street value of $1 million.
The driver, identified by authorities as a Mexican national, was turned over to Homeland Security Investigations and local authorities for state prosecution. The semi-truck was seized by the U.S. Border Patrol.
Justin M. De La Torre, chief patrol agent for the San Diego Sector, said the seizure demonstrated the methods used by transnational criminal organizations to move narcotics.
“This massive seizure of liquid methamphetamine highlights the lengths these transnational criminal organizations will go to smuggle hard narcotics into our communities,” De La Torre said in a statement. “The vigilance of our agents, the reliability of our K-9 units, and our strong multi-agency partnerships are vital to dismantling these illicit smuggling operations and keeping deadly drugs off our streets.”
The case also illustrates the operational challenges involved when contraband is concealed in a commercial vehicle’s fuel system rather than in a trailer or cargo compartment. Removing the substance required specialized personnel because of the volume and the hazards associated with extracting an unknown liquid from a truck’s fuel tank.
For professional drivers, the incident is a reminder that a tractor can draw law-enforcement attention even when it is operating without a trailer. Traffic stops may involve inspections of the vehicle and its equipment, and unusual conditions involving a fuel system can prompt additional scrutiny. In this case, Border Patrol said the discovery followed observations made by an agent and a detection dog.
Authorities did not release additional details about the driver’s alleged role, the truck’s ownership, its route before the stop or the intended destination of the drugs. The available information also does not indicate whether other suspects were arrested or whether additional vehicles were connected to the seizure.
The investigation remains with Homeland Security Investigations and local authorities. Border Patrol said information about suspected smuggling activity may be reported to the agency’s San Diego Sector.
