The seizures took place between July 13 and July 17 at the Calexico Port of Entry, U.S. Customs and Border Protection (CBP) said in a press release.
Calexico CBP officers discovered more than 130 pounds of fentanyl on Wednesday, July 13, after noticing, during an inspection, that a vehicle had been tampered with.
The following day, CBP officers discovered nearly 230 pounds of fentanyl after a canine enforcement screening was conducted.
On Friday, July 15, CBP officers discovered nearly 110 pounds of fentanyl using the port’s imaging machine.
The following day, CBP officers discovered nearly 70 pounds of fentanyl and more than 2 grams of marijuana after inspecting a vehicle and luggage.
And finally, on Sunday, July 17, CBP officers found more than 72 pounds of fentanyl and nearly 190 pounds of methamphetamine using the port’s imaging machine.
CBP said the total estimated value of the narcotics found by Calexico CBP officers was about $ 8.25 million.
All subjects involved were turned over to the custody of U.S. Immigration and Customs Enforcement (ICE), Homeland Security Investigations (HSI) for further investigation. CBP officers seized the narcotics.
Fentanyl is a synthetic opioid behind a massive spike in overdose deaths across the U.S. in recent years. Just a 2 mg dose is enough to kill a user with zero tolerance, whereas 60 mg of heroin is considered a lethal dose.
“Remaining vigilant for something that looks out of place and keeping a keen eye for unusual travel patterns is what our officers are trained to do,” Anne Maricich, CBP acting director of field operations in San Diego said in a statement.
