EASTERN PACIFIC -- A semi-submersible craft sails approximately 300 miles southwest of the Mexico-Guatemala border Monday shortly before it is abandoned by its crew and sinks. The vessel was spotted by a U. S. Customs and Border patrol aircraft on routine patrol in the area. A joint U.S. Navy-U.S. Coast Guard crew from the USS DeWert rescued four suspected drug smugglers and retrieved 11 bales of cocaine that bobbed to the surface.
