Federal prosecutors in Northwest Indiana will reveal public corruption indictments today. For the past three years, federal investigators have been looking into the awarding of a contract for the hauling of debris during the construction of the $45 million Gary baseball stadium in 2001.

The firm Enterprise Trucking of Gary did most of the hauling. The company’s owner is Jewel Harris Sr., a one-time close ally of former Gary Mayor Scott King. Harris served as campaign manager for King, before the two had a falling out.

Following the indictment of other Gary public officials two years ago, investigators revealed that the FBI had tapped Harris’ phones for several months. A source, who asked not to be identified, says indictments are expected to come today as a result of that investigation.
