O.J. didn't do it, apparently, in The Murder Of Nicole Brown Simpson

In 2012, Investigation Discovery aired a documentary about a serial killer named Glen Rogers, who claimed that it was he, not O.J. Simpson, who killed O.J.’s ex-wife Nicole Brown Simpson and her friend, Ron Goldman, in 1994. His brother, Clay, says Glen confessed to the murders while on death row in Florida, and was able to walk him step-by-step through the night in question.
That, of course, doesn’t mean much when the evidence overwhelmingly points towards O.J., or when the LAPD responds with so definitive a statement as this: “We know who killed Nicole Brown Simpson and Ron Goldman. We have no reason to believe that Mr. Rogers was involved.” Goldman’s family, too, has decried the theory. “The overwhelming evidence at the criminal trial proved that one, and only one, person murdered Nicole Brown Simpson and Ronald Goldman,” Fred Goldman told CNN. “That person is O.J. Simpson and not Glen Rogers.” And though O.J. was acquitted of the murders in 1995, he was eventually found responsible in a subsequent civil trial. He also wrote a book called If I Did It. He did it, people.
