Dexter Isaac, a convicted murderer, has finally admitted to carrying out the 1994 Quad Studios shooting of Tupac Shakur.

Not only is he implicating himself in the shooting, but he's taking down the Game's manager,Jimmy "Henchmen" Rosemond. This, ladies and gentlemen, is what we call a "snitch." Not a good look.

He says Rosemond masterminded the botched robbery, which left the legendary rapper shot five times. Isaac told AllHipHop.com on the eve of Tupac's 40th birthday,

"I want to apologize to his [Tupac's] family and for the mistake I did for that sucker [Rosemond]."

He then admitted that he "stayed silent in prison for the past 13 years, doing a life sentence like a real soldier should," but that he is "tired of listening to your [Rosemond's] lies."

"In 1994, James Rosemond hired me to rob 2Pac Shakur at the Quad Studio," said Isaac, who is currently housed in Brooklyn, N.Y.'s Metropolitan Detention Center. He gave me $2,500, plus all the jewelry I took, except for one ring, which he wanted for himself. It was the biggest of the two diamond rings that we took. He said he wanted to put the stone in a new setting for his girlfriend at the time, Cynthia Ried. I still have as proof the chain that we took that night in the robbery."

"Now I'm not going to talk about my friend Biggie's death or 2Pac's death, but I would like to give their mothers some closure. It's about time that some one did, and I will do so at a different time."

Closure? Really, after 13 years, you just now decided to think about Tupac's mother? That's very noble of you, Mr. Isaac.

Then Isaac got real messy and dragged Diddy's name into the whole fiasco WWE-style, saying, "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 fool all of the people all of the time. Mr. Rosemond, I ask you: Are you going to flip on Puffy when the feds get you? To save yourself like you have done in the past?"

We aren't sure how serious we can take the word of a convicted murderer who is currently serving a life sentence in a Brooklyn Prison for the robbery and murder of a taxi cab driver.

This is just a hunch, but we're sure that this is probably just a sad attempt at a no-name prisoner to get some type of fame or recognition.

Since we till believe Tupac is still alive, we'll be sure to bring this to his attention when we see him.
