Apparently for $100 he will give you a tour of where he did his "dirty work" in Vegas; I don't know if that means the spots where he killed people or not. I remember him saying he pulled the trigger on two and was part of two more.

I can just imagine how disgusting most people would feel after handing a murderer $100 to show you the place where blew some guy's brains out.
