by Maureen Callahan

You know, like I say—obviously you have no reason to trust me, but I can tell you right now there is no one who knows me, or who has ever known me, who knows anything about me, really. . . . I’m two different people, basically. And the only person who knows about what I’m telling you, the kinds of things I’m telling you, is me. RUSSO: How long have you been two different people? KEYES: A long time. Fourteen years.

Not all psychopaths are serial killers, but all serial killers are psychopaths.
