Two Colombian nationals arrested in connection with Utah's biggest cocaine bust ever were held on $250,000 bail each in Sevier and Millard county jails after 100 kilos of cocaine were found in a truck on I-70, officials reported.

Jorge Enrique Arango, 27, who gave his address as West Covina, Calif., and Nazly Correa, 30, who gave her address as La Puente, Calif., were stopped for speeding by a Utah Highway Patrol trooper Wednesday afternoon near Elsinore, Sevier County, said UHP spokesman Gary Whitney.He said the trooper noticed that the bed of the 1985 Mitsubishi pickup truck looked higher than normal, and then he saw a couple of bolt holes. He obtained permission to search the truck, but, because of the way the bed was welded, decided it would be better to do the search at county offices in Richfield.

Whitney said the search turned up 100 kilos of cocaine, with a street value estimated at more than $2 million. The previous record cocaine arrest involved about 53 kilos, he said.

Sevier County Jail Commander Garth Larsen said Arango and Correa appeared Thursday before 6th Circuit Judge David L. Mower and were charged with felony counts of possession of a controlled substance with intent to distribute. The judge continued the $250,000 bail that had been set earlier by bail commissioners.

Arango was kept in the Sevier County Jail, but Correa was taken to the Millard County Jail in Fillmore, because the Richfield facility cannot accommodate women, Larsen said.

Both were to be transported to Salt Lake City to appear before a federal magistrate late Friday, said Steve Lough, agent in charge of the Salt Lake office of the Drug Enforcement Administration.
