The reputed leader of the Black Guerilla Family prison gang - who authorities say directed hits on enemies from behind bars while eating lobster and sipping Grey Goose vodka - was sentenced to 12 years in prison late Thursday, federal prosecutors announced.

Eric Brown, 42, was sentenced by U.S. District Judge William D. Quarles Jr., and had faced a maximum of 20 years after pleading guilty on April 27. 

The case highlighted flaws in the state prison system, which the state's top corrections official said were unlike any he had faced in his career in other states. The seven-month investigation led to the indictment on drug and weapons charges of 24 people - including four state prison officers - who authorities believe are leaders or associates of the gang. Search warrants outlined how gang members were able to obtain heroin, direct hits on enemies through so-called "Death Angels" and conduct cell phone conference calls to arrange business with inmates around the state.

Gang associates established a publishing company and have been selling a handbook written by the gang's leader in Maryland, Brown, court documents allege. Titled "Empower Black Families," authorities say the handbook is designed to help new members learn about the gang. It costs $15 for inmates and $20 for non-inmates.
