Cops probing prisoner's claim that he was involved in Tupac Shakur robbery

The NYPD is investigating an online posting from a man who claims to have shot the late rapper Tupac Shakur during a robbery attempt in 1994, a police spokesman said Thursday.

“Detectives plan to talk to him and hear what he has to say,” spokesman Paul Browne said.

Dexter Isaac, who is serving a life sentence in Brooklyn for a murder conviction unrelated to Shakur, claims to have been paid $2,500 by music manager James Rosemond to rob Shakur outside a Manhattan recording studio in November 1994. Shakur was shot five times during the robbery.

Although he survived the shooting, Shakur was murdered in Las Vegas in 1996.

Isaac said in his Web post that he has proof of his role in the ’94 shooting — a chain necklace that he took from Shakur during the robbery.
