MIAMI, FEB. 3 -- New Paraguayan leader Gen. Andres Rodriguez, 64, a millionaire military commander long believed to be involved in large-scale smuggling, apparently moved against ousted strongman Alfredo Stroessner because of political, family and business disputes. Sources close to Rodriguez in Paraguay and U.S. experts said today that the two generals had been at odds over political issues in recent months but that the coup was precipitated by recent quarrels over family and money matters. Rodriguez, who until this week's coup headed Paraguay's most powerful Army unit, for many years had been a protege of Stroessner. One of Rodriguez's three children, Marta, is married to Stroessner's son, Alfredo. Rodriguez had amassed a fortune from smuggling cigarettes, whiskey and possibly illicit drugs, the sources said. Smuggling goods into Paraguay and reshipping them to neighboring Brazil and Argentina is believed to be Paraguay's main source of income by far. Reports of Rodriguez's alleged involvement in drug trafficking most recently surfaced in 1985, when his personal pilot, Juan D. Viveros, was captured along with a plane carrying 43 kilos of cocaine. The cargo earlier had been placed in custody of Rodriguez's 1st Cavalry Regiment, according to published reports at the time. In addition to a mansion in the upper-class neighborhood of Las Carmelitas in Paraguay's capital, Asuncion, Rodriguez is believed to own Cambios Guarani, one of the country's largest foreign exchange houses; the Munich beer brewery, the second largest in the country; and the Impaco copper wiring manufacturing firm. Recently, Rodriguez had sided with the "traditionalist" wing of Stroessner's ruling Colorado Party, which had sought to distance itself from the Paraguayan strongman. The rift between the two generals grew wider when their two children split up amid reports that Stroessner's son Alfredo was undergoing drug and alcohol treatment. In late January, in what was widely perceived to be a move against Rodriguez's Cambios Guarani, Stroessner ordered the closing of all foreign exchange companies, citing a run on the national currency. At the same time, Stroessner allowed another son-in-law, a bank owner, to open a foreign exchange division, opposition sources said. "If you think of Paraguay as run by a Mafia, then you'll understand it better," said Richard Allan White, a research fellow at the Washington-based Council on Hemispheric Affairs who specializes on Paraguay. "This is like one family in a Mafia organization fighting against another." Aldo Zucolillo, publisher of ABC Color, a newspaper shut by Stroessner in 1984, said in a telephone interview from Asuncion that he is confident Rodriguez will abide by his promises to restore freedom of the press and lead a move toward democracy after 34 years of dictatorship. "I think he means it," Zucolillo said, speaking over the noise of celebrants in Asuncion. "After all these years of waiting for a general who would lead us back to democracy, I think we've found him." But researcher White, a historian, was more skeptical. "This coup may prevent a real democratic change, which people hoped would happen once Stroessner died or left power. Now, it looks like things have changed to remain the same."
