BOSTON (AP) — Jurors in the racketeering trial of James "Whitey" Bulger are heading into their fifth day of deliberations after mulling over the charges against the reputed crime boss for about 28 hours without reaching a verdict.

The jury will return to federal court in Boston on Monday to continue deliberations.

Bulger, 83, is charged with a litany of crimes in a sweeping 32-count racketeering indictment, including 19 killings, extortion, money laundering and weapons violations.

Within the main racketeering charge against Bulger are 33 separate criminal acts, including all of the killings. The jury must find that Bulger committed at least two of the acts within 10 years of each other to find him guilty of racketeering.

Bulger fled Boston in 1994 on the eve of an indictment and was one of the nation's most-wanted fugitives until his capture in Santa Monica, Calif., in 2011.

Prosecutors say he was a longtime FBI informant who was protected by corrupt FBI agents. Bulger's lawyers have strongly denied that he was an informant and say he paid FBI agents to get information about wiretaps and investigations so he and his cohorts could stay one step ahead of the law.

The jury heard testimony from 72 witnesses and saw 840 exhibits during the two-month trial.
