South Boston mobster James "Whitey" Bulger, convicted of 31 charges including racketeering, extortion and money laundering in August, was sentenced to two life sentences and an additional five years in federal prison Thursday.

Judge Denise Casper handed down the sentence after several members of victim's families gave emotional statements in court. Bulger, 83, did not look at the family members save for a brief glance at Steven Davis, who challenged Bulger to “Look at me, you piece of shit!”

In its verdict, the jury linked Bulger to 11 of the 19 murders he’d been accused of, though it returned "no finding" on the racketeering count of the murder of Davis' sister, Debra. The jury found Bulger guilty of 31 charges, included racketeering, extortion, and money laundering.

Bulger lawyer J.W. Carney said after the verdict was delivered in August that Bulger plans to appeal.
