Nation IN BRIEF : FLORIDA : Top Cocaine Boss to Testify on Noriega

Carlos Lehder, the most important Colombian cocaine boss ever jailed by the United States, is expected to testify for the government early this week in the drug conspiracy case against Manuel A. Noriega. Sources close to the case said that Lehder, serving life imprisonment but offered a deal for his testimony, was moved secretly from his prison quarters in Illinois to a downtown Miami holding cell in recent days. There has been considerable arguing among federal officials as to whether Lehder should be brought in to testify, a source close to the trial said. “He’s a loose cannon,” the source said.
