LOS ANGELES: Former American football star O.J. Simpson has spent nearly nine years in prison. Not for the grisly 1994 murders of his ex-wife and a male companion— he was famously acquitted in that case. No, Simpson has been behind bars for his role in a September 2007 armed robbery of two sports memorabilia dealers at a Las Vegas resort. He could soon go free. A Nevada parole board will hold a hearing in Carson City on Thursday to decide whether the former National Football League (NFL) star and actor should be released from prison. Simpson was convicted in October 2008 of armed robbery, assault, kidnapping and other offenses after he and five associates—two of whom were armed—ambushed the two sports memorabilia dealers in a casino hotel room. Simpson, 70, who earned the nickname “The Juice” during his playing days, claimed he was just trying to recover mementos from his career which he said the dealers had stolen.
