A drug bust at the U.S.-Mexico border in Texas earlier this week exposed nearly $7 million worth of narcotics at a cargo facility.
Border agents at the Pharr-Reynosa International Bridge cargo facility were alerted to a commercial shipment of stone blocks on Monday. Officers with drug-sniffing dogs discovered packages of narcotics hidden within the shipment.
The bridge crosses the Rio Grande, connecting Texas with Mexico.
Officials said they seized 35 packages believed to be methamphetamine weighing 320 pounds, seven packages believed to be cocaine weighing almost 40 pounds and two packages believed to be heroin weighing around seven pounds.
The total street value is estimated at $6,998,000, border officials said.
The drugs and the trailer they were in were turned over to U.S. Customs and Border Protection and the case is being investigated by Homeland Security Investigations agents.
