O.J. had an accomplice

      I came across an article, which spoke of O.J.  having an accomplice in the slaughter of Nicole Brown and Ron Goldman. The article said that this person helped O.J. with the stabbing and that he took the evidence afterwards. This information was not new but it was ignored during the trail back in 1994. This was something that I could not fully understand and I was wondering if anyone could possibly help me try to understand the reasons for ignoring such information. Thanks. 

Here's a link to the article.. http://www.celebdirtylaundry.com/2014/o-j-simpson-nicole-brown-ron-goldman-double-murder-accomplice-photo/ 

 Here's a link to the story of the accomplice, Glen Rogers. http://www.theblaze.com/stories/2012/11/19/could-this-be-nicole-browns-murderer-chilling-documentary-suggests-o-j-was-in-fact-innocent/
