Rogers has confessed in the past for murders he says he committed but didn't really commit. Law enforcement officials think he's trying to get out of Florida death row by confessing to other crimes in different states. He confessed to Ohio authorities that he murdered someone in Ohio, hoping to get transferred to an Ohio prison. Turns out he was full of shit and knew nothing of the true details of the crime.
How does he (or OJ) explain the victims' blood being in OJ's car and on OJ's sock? How does he explain the fact that that OJ's shoe print was found near the murder scene? If OJ was innocent, why did he grab all his cash, his passport, etc. and try to flee the country? And if he did do it, how does this exonerate OJ in any way - Rogers claims OJ told him to kill Nicole.
I don't believe for one second that Rogers killed Nicole and Ron.
