Flemmi testified against Connolly at the latter's trial for the murder of John Callahan, the former president of World Jai Alai. Callahan had been killed in 1981 after he was implicated in the murder of his successor as president, Roger Wheeler. According to Flemmi, Connolly told him and Bulger that Callahan could potentially turn state's evidence and implicate them in Wheeler's murder. He also testified against Bulger in the latter's 2013 trial for murder and racketeering, at which Bulger was sentenced to life plus five years.
