A border detection dog named K9 Immo helped Customs and Border Protection officers uncover more than 65 pounds of fentanyl powder hidden inside a vehicle in San Diego, according to the agency’s local field office. The stop adds yet another hefty haul to a string of recent drug seizures at Southern California ports of entry.
Director of Field Operations Sidney Aki highlighted the bust on X, giving K9 Immo and the San Diego team a public shout-out for spotting the concealed narcotics.

Where This Bust Fits In
San Diego’s ports of entry have been churning out big numbers lately. In one recent July alone, CBP officers seized more than 9,800 pounds of narcotics, including about 326 pounds of fentanyl, according to the Times of San Diego. Local seizures like these track with a broader Southwest Border problem that federal agencies have pushed higher on the priority list in recent years.
Multi-agency enforcement efforts have produced massive hauls and a steady stream of prosecutions in the region. The U.S. Attorney’s Office for the Southern District of California has described a 2023 enforcement surge that cut into smuggling routes, pulled thousands of pounds of fentanyl out of circulation, and led to dozens of federal cases and arrests, as detailed by the U.S. Attorney’s Office, Southern District of California.
Fentanyl’s punch is what keeps these border busts in the spotlight. The DEA notes that roughly two milligrams can be a potentially lethal dose and that a single kilogram can represent hundreds of thousands of lethal doses. With that kind of potency, stopping pounds of powder at the border is treated as a top-tier public safety mission.
What Happens Next
After a seizure like this, the drugs are typically sent out for laboratory confirmation, and the case is referred to Homeland Security Investigations for follow-up work that can end up in federal court. Past district-wide operations show how forensic testing and interagency investigations feed directly into criminal filings, according to the U.S. Attorney’s Office, Southern District of California.
Aki’s post did not specify which port of entry was involved or whether anyone was arrested in connection with the stop. As posted by Director of Field Operations Sidney Aki, the brief announcement was the San Diego Field Office’s only public comment and offered no further operational details.
