The trial of Boston crime boss James "Whitey" Bulger is nearing a pivotal moment, as the prosecution tries to cement its case by calling his former partner to testify.
Stephen "The Rifelman" Flemmi is expected to take the witness stand Thursday and to say that he and Mr. Bulger cooperated in killings that included two women.
Bulger was captured in 2011 after a 16-year manhunt. Federal prosecutors say Bulger ran an organized-crime outfit with Mr. Flemmi that was responsible for extortion and at least 19 murders. Flemmi, who is serving a life prison sentence after admitting to 10 murders, is central to their case.
