Impersonator Josh Harraway?
I spent a few hours last night reading and forming opinions over this one, as well as studying facial features. I don't believe for a number of reasons that those photos are real, and believe me I'm the king of conspiracy theories and wanting to believe this sort of thing. I think this is a look alike, a dead ringer (no pun intended) for 2pac.
Until his mother or Snoop makes a public statement on the matter, or until the "resurrection tour 2010 is announced" I think this is just a good-look-alive (Impersonator Josh Harraway) look him up.
