LAS VEGAS , Nevada ( CNN ) -- A jury of nine women and three men -- none of them black -- was seated Thursday for the trial of O.J . Simpson on kidnapping and armed robbery charges . Judge Jackie Glass decided prosecutors had a `` race-neutral '' reason for dismissing the potential juror . The judge made no official mention of the jury 's makeup , but prosecutors revealed in court that no blacks were on the jury . A black man and black woman , however , are among six alternate jurors . Defense attorneys had argued the prosecutors were deliberately trying to exclude blacks , but Judge Jackie Glass denied their challenges . Opening arguments are scheduled to begin Monday in the case against Simpson and a co-defendant , Clarence Stewart . Prosecutors say Simpson and five other men stormed into a Las Vegas hotel room on September 13 , 2007 to recover sports memorabilia that Simpson said belonged to him . Prosecutors say at least two men with Simpson had guns as they robbed a pair of sports memorabilia dealers . If convicted on all counts , Simpson faces a possible sentence of life in prison . He has pleaded not guilty and has told CNN he was trying to get his property back . Four of five Simpson 's original co-defendants have struck deals with the prosecution to testify against Simpson . One testified in a pre-trial hearing that `` O.J . Simpson wanted me to have a weapon . '' Another testified that Simpson `` wanted me to help him acquire some guns . '' An attorney for Simpson , Yale Galanter , has disputed that . `` O.J . Simpson did not know that there were guns in that room , '' Galanter said .
