So I'm watching the Is OJ Innocent series on the OWN network. They are saying they think Jason, OJ's son, may have helped him (or done) the murders. They think he's the "Charlie" in OJ's book, and it explains the extra car that limo driver saw in the Rockingham driveway. Jason's time card is stamped, except on that night of the murder, which is his alibi, when it's handwritten. I'm not sure whether I buy it or not, but it's an interesting theory.
