The 33 acts underpin a racketeering charge against Bulger. The acts include the 19 killings Bulger is accused of playing a role in, plus extortions, money-laundering and narcotics distribution.

The judge told jurors they should try to say whether prosecutors proved each act.

The 83-year-old Bulger was one of the nation’s most wanted fugitives after he fled Boston in 1994. He was captured in Santa Monica, Calif., in 2011.
