Tupac ShakurEarlier this week, the Internet went berzerk when a former associate of rap industry vet, Jimmy “Henchman” Rosemond, came forward and took credit for the 1994 Quad Studio shooting of Tupac Shakur in New York.

While fans celebrated Pac’s legacy on Thursday (June 16), making him a worldwide trending topic on Twitter with the hashtags, #Tupac and #THUG LIFE, word spread of the confession from inmate Dexter Isaac, who confessed to the robbery/shooting in a letter to AllHipHop.com, claiming that Rosemond paid him $2,500 for the job.

The shooting sparked the now-infamous East/West rap war between Pac and the late Notorious B.I.G., and left Pac shot five times.

Rosemond (who is still on the run from a federal indictment for drug trafficking) has responded, via his lawyer, refuting Isaac’s story.

“It’s a flat-out lie,” he told the New York Daily News. “Dexter Isaac is not claiming this 17 years later to clear his conscience. He’s doing it because he’s told anybody who will listen he doesn’t want to die in prison. He has kids and wants to work off his sentence. He can’t be trusted.”

Isaac claims that due to the statue of limitations, where no one can be prosecuted for the crime, he decided to come forward with the information to give closure to the family of Tupac.

“I want to apologize to his family [Tupac Shakur] and for the mistake I did for that sucker [Jimmy Henchman],” Isaac told AllHipHop.com. “I am trying to clean it up to give [Tupac’s and Biggie’s] mothers some closure.”

Rosemond and his defense team, however, say Isaac is lying. He believes that the government is using incarcerated informants to build a case against him. In a statement released after news of the indictment, he attacked Isaac’s credibility.

This is one of the reasons why Isaac says he wanted to talk. He says he’s just “plain tired of listening to [Rosemond’s] lies.”

“Jimmy, you and Puffy like to come off all innocent-like, but as the saying goes: you can fool some of the people some of the time, but you cannot foll all the people all of the time,” Issac said. “Are you going to flip on Puffy when you Feds get you? To save yourself like you have done in the past? Because that’s what a rat does. So in closing, we shall see who the rat is, in the near future.”

Pac famously fingered Rosemond/Henchmen in his 1996 song “Against All Odds,” implying that he was set-up by the rap manager.

“And did I mention, promise to pay back Jimmy Henchman in due time?/ I know you bitch n****s is listenin’, the world is mine/ Set me up, wet me up, n****s stuck me up/ Heard the guns bust, but you tricks never shut me up,” Pac raps.
