After deliberating for 28 hours over four days, a federal jury Friday broke for the weekend without announcing a verdict in the trial of reputed Boston crime boss James "Whitey" Bulger.

The eight-man, four-woman panel will resume work at 9 a.m. Monday to continue processing testimony from 70 witnesses and over 800 exhibits compiled during the seven weeks of the trial.

Bulger, 83, is accused of racketeering, including involvement in 19 killings, and also 13 counts of extortion and money-laundering during a 20-year "reign of terror" that defined South Boston from the early '70s through 1995, when Bulger fled Boston.
