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 spend the rest of his life in prison.

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.

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.

Simpson's co-defendant, Clarence "C.J." Stewart, 54, also was found guilty on all charges and taken into custody.

Simpson showed little emotion as officers handcuffed him and walked him out of the courtroom. His sister, Carmelita Durio, sobbed behind him.

From the beginning, Simpson and lawyers argued the incident was not a robbery, but an attempt to reclaim mementos that had been stolen from him. He said he did not ask anyone to bring a weapon and did not see any guns.

The defense portrayed Simpson as a victim of shady characters who wanted to make a buck off his famous name, and police officers who saw his arrest as an opportunity to "get" him and avenge his acquittal.
