Investigators questioned O.J. Simpson and named him a suspect Friday in a break-in at a casino hotel room involving sports memorabilia. The break-in was reported at the Palace Station casino late Thursday night, police spokesman Jose Montoya said. He said investigators determined the break-in involved sports collectibles. "When they talked to him, Simpson made the comment that he believed the memorabilia was his," Montoya said. "We're getting conflicting stories from the two sides."
