A federal magistrate in Alexandria yesterday ordered the extradition of a Guatemalan couple to Florida where they have been indicted in connection with the July 8 kidnaping of the wife of the former Salvadoran ambassador to the United States.

Magistrate W. Harris Grimsley also ordered that Juan Jose Caceres, 43, and his wife, Dora Ileana, 32, both of 5631 Derby Court, Alexandria, remain held without bond. They and five others were indicted by a federal grand jury in Miami Friday on kidnaping and conspiracy charges.

The kidnaping victim, Clelia Quinonez, 53, was abducted as she drove up in front of her Coral Gables, Fla., home. She was later driven to an apartment in Northwest Washington, where she was held until July 14 when FBI agents rescued her.

The next day, the Cacereses and their 19-year-old nephew, Jorge Alfredo Santiago Castro, who lives with them, were formally charged in Alexandria federal court, but those charges were dropped after the Miami grand jury presented the indictments.

Santiago Castro was not named in the Florida indictments, and he was released yesterday..

Also indicted on charges of kidnaping and conspiracy were: Clifford Bibbs, 23, of 1303 Euclid St. NW; Robert (Tony) Gerald, 19, of 4913 Illinois Ave. NW; Mack Carr, 18, of 2327 15th St. NW; Jennifer Brown, 27, of 2327 15th St. NW; and Salvador Lacayo, 35, of Miami.

In addition, federal prosecutors in Alexandria have filed kidnaping and conspiracy charges against Craig Blas, 16, of 5479 Sheffield Court, Alexandria. They said they plan to ask that he be tried in Miami as an adult.
