Tupac Shakur shooting confession surfaces online, NYPD investigates

(CBS/WCBS/AP) NEW YORK - New York City police have begun an investigation into an online posting supposedly from a convicted felon who claims to have shot and robbed slain rapper Tupac Shakur.

If police determine the post to be legitimate they will look to interview the prisoner, said police spokesman Paul Browne.

The claim was posted to the website AllHipHop.com. According to the site, a man named Dexter Isaac says he was paid $2,500 by music executive James Rosemond to rob Shakur outside a studio in Manhattan in 1994. Shakur suffered gunshot wounds but eventually recovered. He was later killed in 1996 in an unsolved murder, reports CBS affiliate WCBS.

Shakur publicly blamed the 1994 attack on Christopher "Notorious B.I.G." Wallace and Sean "P-Diddy" Combs, who he thought did it as payback since he rejected Combs's record label, reports The Guardian.

But, now Isaac is claiming the attack was his doing.

"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," says Isaac, adding that the Rosemond also allowed him to keep some of the jewelry he stole from Shakur.

"I still have as proof the chain we took in the robbery," Isaac wrote.

It's not clear if the purported confession is genuine.
