O.J. Simpson’s lawyers are questioning Tom Riccio in a Vegas courtroom, hoping to undermine the sports memorabilia collector’s testimony. Riccio's audio recording of a cursing and angry Simpson during an alleged arm robbery was released on TMZ.com. Riccio testified that O.J. was only interested in retrieving his own memorabilia that he believed was stolen, and he had no interest in the other items. If the judge rules there is enough evidence to go to trial, O.J. will face charges of armed robbery and kidnapping and could face life in prison if convicted. For more on today’s hearing, click here.
