U.S. Customs and Border Protection officers seized nearly $2.8 million in fentanyl and methamphetamine during two separate inspections at the San Ysidro Port of Entry in San Diego in April 2026, according to CBP. The seizures occurred over a six-day period and resulted in multiple arrests, highlighting ongoing enforcement at one of the busiest US-Mexico border crossings.
U.S. Customs and Border Protection (CBP) reports significant narcotics interdictions at southern border ports of entry, with San Ysidro remaining a critical checkpoint for detecting concealed drug shipments entering the United States.
Overview of two San Ysidro drug seizures within six days
| Indicator | Recent Movement | Context |
|---|---|---|
| Total narcotics seized | Nearly $2.8 million value | Combined fentanyl and meth seizures reported by U.S. Customs and Border Protection in April 2026 |
| April 19 seizure | 116+ pounds drugs | CBP officers discovered fentanyl and meth concealed in a vehicle roof using imaging and canine alerts |
| April 13 seizure | 14.02 pounds fentanyl | CBP officers identified concealed narcotics in rear panels during secondary inspection at San Ysidro Port of Entry |
Summary table detailing dates, drug types, weights, and estimated values
The seizures involved fentanyl powder and methamphetamine, with CBP estimating a combined street value of nearly $2.8 million. Additionally, the April 19 case accounted for the majority of the total, exceeding $2 million in estimated value. The seizures reflect continued attempts to transport high-value narcotics through official crossings.

Breakdown of fentanyl and meth quantities and detection methods used
On April 19, CBP officers at the San Ysidro Port of Entry referred a 2019 Honda Pilot for secondary inspection. During the process, a nonintrusive imaging system identified structural anomalies, while a CBP canine team alerted to the same area, according to U.S. Customs and Border Protection.
A subsequent physical inspection uncovered 94 packages hidden in the vehicle’s roof. CBP reported approximately 35 pounds of fentanyl powder valued at nearly $1.95 million, alongside more than 80 pounds of methamphetamine valued at approximately $80,550. The driver, identified by CBP as a 27-year-old Mexican national, was taken into custody and faces federal narcotics importation charges.
Details of April 13 rear panel concealment case
On April 13, CBP officers conducted a secondary inspection of a 2025 Toyota Corolla at the same port of entry. A CBP canine alert during pre-primary operations triggered further inspection, leading officers to use imaging technology to detect anomalies in the rear quarter panels, according to CBP.
Officers then located six concealed packages containing 14.02 pounds of fentanyl powder, which CBP stated is equivalent to approximately 509,818 fentanyl pills with an estimated value of $764,727. The 20-year-old driver, identified by CBP as a Mexican citizen enrolled in the Secure Electronic Network for Travelers Rapid Inspection program, was arrested and referred for federal prosecution.
Inspection methods and enforcement techniques used by CBP
- Canine detection units: CBP reported trained dogs alerted to concealed narcotics in both cases, prompting deeper inspections
- Nonintrusive imaging: CBP used scanning technology to identify structural anomalies in vehicles before physical searches
- Secondary inspections: CBP officers conducted detailed follow-up inspections after initial screening flagged potential concealment
- Enforcement outcome: CBP confirmed arrests, vehicle seizures, and referral of cases for federal prosecution
Official statement and operational significance of seizures
Statement from San Ysidro Port Director on enforcement impact
“Smugglers use complex techniques to conceal dangerous narcotics like fentanyl and methamphetamine,” said Mariza Marin, Port Director for the San Ysidro Port of Entry.
“Their efforts directly prevent these deadly narcotics from reaching our streets, protecting countless lives,” Marin added.
Marin, referencing the role of CBP officers, canine teams, and inspection technology.
The seizures demonstrate a pattern of interdiction at a major port of entry, where CBP data shows repeated attempts to conceal narcotics within passenger vehicles. This activity reflects ongoing enforcement priorities at the southwest border, where CBP reports intercepting illicit substances while facilitating lawful travel and trade.
CBP’s reported seizures at the San Ysidro Port of Entry illustrate continued enforcement against fentanyl and methamphetamine trafficking through official border crossings. The combination of detection technology, canine teams, and inspection protocols contributed to the interception of high-value narcotics shipments.
These operations, as documented by U.S. Customs and Border Protection, highlight the scale and persistence of drug smuggling attempts while demonstrating the agency’s role in disrupting distribution networks at the US-Mexico border.
