Prosecutors and defense lawyers are exploring the possibility of a plea deal for the last of three men charged in the 2002 killing of Run-DMC star Jam Master Jay, both sides said Thursday, less than six weeks after two co-defendants were convicted.

The talks just began, and it’s unclear what federal prosecutors might be willing to offer Jay Bryant, or what he might be willing to accept. Federal prosecutors and Bryant’s lawyer, Cesar de Castro, declined to comment after court.
