In December 1994, after being tipped off by his former FBI handler about a pending indictment under the Racketeer Influenced and Corrupt Organizations Act, Bulger fled Boston and went into hiding. For 16 years, he remained at large. For 12 of those years, Bulger was prominently listed on the FBI Ten Most Wanted Fugitives list. Beginning in 1997, the New England media exposed criminal actions by federal, state, and local law enforcement officials tied to Bulger. The revelation caused great embarrassment to the FBI. In 2002, Special Agent John J Connolly was convicted of federal racketeering charges for helping Bulger avoid arrest. In 2008, Special Agent Connolly completed his term on the federal charges and was transferred to Florida where he was convicted of helping plan the murder of John B Callahan, a Bulger rival. In 2014, that conviction was overturned on a technicality. Connolly was the agent leading the investigation of Bulger.
