LAS VEGAS -- O.J. Simpson, who went from American sports idol to celebrity-in-exile after he was acquitted of murder in 1995, was found guilty Friday of robbing two sports-memorabilia dealers at gunpoint in a Las Vegas hotel room.

Simpson, 61, could go to prison for life.

A weary and somber Simpson released a heavy sigh as the charges were read by the clerk in Clark County District Court. He was immediately taken into custody.

The Hall of Fame football star was convicted of kidnapping, armed robbery and 12 other charges for gathering up five men a year ago and storming into a room at a hotel-casino, where the group seized several game balls, plaques and photos. Prosecutors said two of the men with him were armed; one of them said Simpson asked him to bring a gun.

Simpson's co-defendant, Clarence "C.J." Stewart, 54, was also convicted on all charges.

The verdict came 13 years to the day after Simpson was cleared of murdering his ex-wife and a friend of hers in Los Angeles in one of the most sensational trials of the 20th century.
