Another federal courthouse in Miami is riddled with mold, according to a private study last fall commissioned by the U.S Attorney’s office. The study found mold spores in the air throughout the James Lawrence King building in downtown Miami. U.S. Attorney Alex Acosta said March 10 he asked for the study after mold problems at the Dyer Courthouse across the street became public last year following the unusual death in 2006 of a federal judge from a mysterious pulmonary illness. Acosta said the study’s report found “areas of concern” spread throughout the building. He said it was not unusual for one floor to be affected on one side more than the other.

He also confirmed a small number of employees have complained about respiratory illness. Sources say some workers have chronic bronchitis. Acosta said the study — which he did not release — recommended an upgrade of the building’s air conditioning and humidity control system followed by the cleaning of the air handling units and replacing insulation in air ducts.
