Transcript for OJ Simpson's Self-Described 'Prison BFF' on Simpson's Life Behind Bars

Now an ex-correctional officer who claims to be o.j.'s confidant is speaking out. I'm not black. I'm O.J. Reporter: Cocky and confident. It's the on-screen depiction of O.Y. Simpson in "American crime story." But tonight another image of the juice. As an aging inmate. O.j. Simpson is not suffering in prison. He's eating well. He's exercising well. Reporter: Retired correctional officer Jeffrey Felix telling his version of the story in a self-published book, "Guarding the juice: How O.J. Simpson became my prison bff."
