LAS VEGAS - Former football star O.J. Simpson has been sentenced to at least 15 years in prison for a botched attempt to recover sports mementos and personal items from two collectibles peddlers. He will be eligible for parole in six years. Simpson stood stone-faced when the judge rattled off his punishment after he pleaded with her that he didn't mean to steal from anybody when he tried to retrieve memorabilia. He appeared ready to break down in tears as he told her that he was "sorry and confused" before going into a rambling and emotional 5-minute declaration. Glass also ruled before sentencing that Simpson cannot be freed on bail pending possible appeal. In earlier proceedings, neither Simpson, who was acquitted of the 1994 slayings of his ex-wife and her friend in Los Angeles, nor his co-defendant and former golfing buddy, Clarence "C.J. Stewart, testified at trial. They were convicted Oct. 3 of 12 criminal charges, including kidnapping and armed robbery. Las Vegas Judge Jackie Glass rejected to his apology Friday and said, "It was much more than stupidity."
