Ex-Partner Takes Witness Stand Against Bulger

Based on the last 15 minutes of testimony Thursday in the trial of James "Whitey" Bulger, Friday will likely be a day filled with fireworks and insight into Boston's criminal underworld.

Convicted murderer Stephen Flemmi returns to the stand for a second day Friday. He was a partner in what the defense admits was Bulger's criminal enterprise. And in his first appearance, Flemmi quickly contradicted Bulger's claim that he was never an FBI informant.
