Tupac Shakur (Chi Modu/EPHOTOS/Brooklyn Museum of Art)

“Jimmy, I say to you: I have kept your secrets for years,” Isaac told AllHiphop from prison. “I have stayed silent in prison for the past 13 years, doing a life sentence like a real soldier should, when you and everybody have turned your backs on me. ... Now I would like to clear up a few things, because the statute of limitations is over, and no one can be charged, and I'm just plain tired of listening to your lies. In 1994, James Rosemond hired me to rob 2Pac Shakur at the Quad studio. He gave me $2,500, plus all the jewelry I took, except for one ring, which he wanted for himself.”

Had Tupac still been alive, he would have turned 40 today.

Isaac and Rosemond have been linked to Shakur’s death before. On his song “Against All Odds,” Shakur blamed Rosemond for his shooting, singing, “Promised [to] pay back Jimmy Henchman in due time.” Tupac’s former protege E.D.I. Mean reacted to the news without surprise.

Rosemond is currently believed to be on the run due to federal gun charges.

Isaac did not admit to the September 1996 murder of Shakur, who was shot multiple times after a boxing match in Las Vegas and died six days later. Isaac also did not comment on the March 1997 slaying of Notorious BIG. Both murders remain unsolved.

“But I would like to give their mothers some closure,” Isaac wrote. “It's about time that someone did, and I will do so at a different time.”

E.D.I. Mean told MTV that he thinks Isaac’s confession will help solve the murders of both Tupac and Biggie

“This will really lead up to their actual murderers,” E.D.I. Mean said. “Both Big and ’Pac and everybody can move on, and this will be like some closure for not only the families, but the whole hip-hop community, because it’s been an open wound since 1996 and 1997.”

Other rappers mourned Shakur’s death today, tweeting:

Listen to the song “Dear Mama,” which Shakur wrote as an ode to his mother, Afeni Shakur. It was released on Feb. 21, 1995, three months after he was shot and robbed by Isaac:
