"Whitey" Bulger was sentenced to two life terms in prison.

It is the end of an era for the Boston mob. A federal judge sentenced former mob boss James "Whitey" Bulger to spend the rest of his life in prison. In sentencing, the judge called “Whitey” Bulger’s crimes "almost unfathomable."

“Whitey” Bulger, 84, was convicted of 11 murders, extortion and drug dealing during the time he was boss of the Winter Hill crime gang in Boston during the 1970s and '80s. Bulger lammed it out of Boston in 1994 after being tipped off that he was going to be arrested.

Before imposing two consecutive life sentences plus five years, U.S. District Judge Denise Casper said "The scope, the callousness, the depravity of your crimes are almost unfathomable. The testimony of human suffering that you and your associates inflicted on others was at times agonizing to hear and painful to watch. At times during the trial I wished that we were watching a movie, that what we were hearing was not real."

Judge Casper also ordered Bulger to pay $19.5 million in restitution to his victims.

Bulger’s trial went on for two months and was interrupted by outbursts from the accused and former gangmates. In August, a jury found Bulger guilty of 31 of 32 criminal counts

“Whitey” Bulger’s life was the inspiration for Martin Scorsese's "The Departed," which won the Best Picture Oscar in 2006.

Through his attorney, Whitey Bulger said the trial was "a sham."

After the hearing Whitey Bulger’s attorney, J.W. Carney, told reporters "It took a lot of discipline for him not to react emotionally to some of the things that were said, and he's proud he was able to conduct himself in that fashion."

Defense attorney Henry Brennan said Bulger would appeal the conviction.
