Almost exactly one year ago, Dexter Isaac, an inmate serving a life sentence on a murder-for-hire conviction, went public with his involvement in the 1994 robbing and shooting of Tupac Shakur at Quad Studios in Manhattan. This was the incident that sparked the East Coast/West Coast hip-hop feud: Tupac was at Quad that night to meet Biggie Smalls and Sean "Diddy" (then Puff Daddy) Combs, and believed they were behind the assault. Within three years, both he and Biggie would be dead. And according to Isaac, who says he pulled the trigger that night at the recording studios, the whole thing was called in by James Rosemond, a.k.a. Jimmy Henchman, a rap music manager/hanger-on with a long list of criminal allegations to his name. Now Henchman's got one more notch on his rap sheet, and this one's a bit more concrete. The New York Times reports that on Tuesday a federal jury in Brooklyn convicted Jim of running a multi-million-dollar drug trafficking operation. Says U.S. attorney Loretta E. Lynch, who is apparently as awesome at convicting criminals as she is with providing punchy wrap-up quotes about said convictions: "Rosemond built and ran this drug trafficking organization in order to personally enrich himself and his associates. And profit he did. [Insert whatever dramatic pause noise you'd like.] The paydays are over for Jimmy Henchman.”
