In 1988, south suburban mob boss Albert Tocco of Chicago Heights was indicted for a wide range of crimes, including racketeering, murder, extortion, and arson. He was also implicated by his wife in the murder of Anthony Spilotro, which was depicted in the movie "Casino". Although he was never charged with the Spilotro killing, he would be convicted on many other charges in 1990 and sentenced to 200 years in prison. During the trial, LoBue's name was mentioned along with another Panici ally, former South Chicago Heights mayor Donald Prisco. Testimony alleged that LoBue and Prisco were accepting bribe money from Tocco in exchange for their help in keeping the garbage-hauling license for both cities in the hands of Tocco's Chicago Heights Disposal. This led federal investigators to open a wide-ranging probe of public corruption in Chicago Heights. City Street Department superintendent Ernest Molyneaux pleaded guilty to bribery-related charges in 1990 and cooperated with the investigation, leading to the indictments of LoBue and Prisco later that year. The two were charged with multiple racketeering violations under the Racketeer Influenced and Corrupt Organizations Act (RICO). The investigation also led to the indictments of several other city officials on charges of bribery, tax evasion and other crimes. Under this cloud of controversy, Panici chose not to seek re-election as mayor in 1991. His hand-picked successor, Douglas Troiani, won an easy victory against Sadus, who had split with the party.
