The U.S. attorney's office has filed a criminal complaint against two Colombian nationals arrested during one of Utah's largest cocaine seizures.

A federal grand jury will decide later whether to indict Jorge Enrique Arango and Nazly Correa, who were stopped by a Utah Highway Patrol trooper Nov. 16 for speeding on I-70 near Elsinore, Sevier County.Arango, 27, gave his address as West Covina, Calif., and Correa, 30, said she lives in La Puente, Calif.

UHP spokesman Gary Whitney said that hidden in their truck was 100 kilograms of cocaine, which has a street value of $2 million. He said the trooper noticed that the bed of the pickup looked higher than normal and searched the vehicle.
