A traffic stop conducted on a semi truck by U.S. Border Patrol agents resulted in the discovery of hundreds of pounds of illegal drugs.

At 6:40 p.m. on April 8, agents from the Newton-Azrak station initiated a traffic stop on a semi truck traveling north on I-215 in Murrieta, California.

A canine unit was brought to the scene, and the dog alerted to the possible presence of illegal drugs.

Border Patrol agents continued investigating and discovered “anomalies in the fuel tanks and the fluid inside.”

The truck and driver were transported to a Border Patrol station for further investigation.

“At the station, agents discovered an aftermarket compartment within both diesel tanks. The fluid in the compartments tested positive for the characteristics of methamphetamine. Homeland Security Investigations (HSI) and hazmat personnel were contacted to assist with extraction of the liquid. A total of 22 five-gallon buckets were retrieved from both tanks. The weight of the methamphetamine was 761 pounds, with an estimated street value of $684,900,” U.S. Customs and Border Protection (CBP) said.

Officials called this the San Diego Sector’s largest methamphetamine seizure in the past two years. Prior this this drug seizure, the San Diego Sector had seized 347 pounds of methamphetamine in fiscal year 2025.

The drugs and truck driver were handed over to HSI. The truck was seized by Border Patrol.

CBP says that the driver faces federal charges for possession with intent to distribute a controlled substance.

“Foreign terrorist organizations will use every trick in the book to get their drugs into the country,” said Jeffrey D. Stalnaker, Acting Chief Patrol Agent of the San Diego Sector. “The agents of San Diego Sector are the best in the business and will continue to target, interdict, and dismantle these organizations.”
