He’s off the hook again. A Nevada parole board ruled Thursday that 70-year-old former NFL star O.J. Simpson could go free after serving nine years in prison for armed robbery. Simpson received a 33-year sentence, with possibility for parole, in 2008 for staging a botched sports memorabilia heist in Las Vegas. That conviction came on the exact day — 13 years later — that he was acquitted of murder in the slayings of his ex-wife and friend. Simpson, who took “full responsibility” for the crime, could be released as early as October 1.
