Jury selection in O.J. Simpson’s Las Vegas robbery-kidnapping trial begins Monday morning and is expected to take a month, court officials in Las Vegas said.

Simpson and his co-defendant Clarence Stewart are facing 12 charges, including armed robbery and kidnapping, following a heated encounter last September with two sports collectibles dealers at a Las Vegas hotel-casino. If the two are convicted on all charges, they could face up to life in prison.

Four other co-defendants, Charles Cashmore, Walter "Goldie" Alexander, Michael "Spencer" McClinton and Charles Ehrlich, pleaded guilty reduced charges, and agreement which was offered to them in exchange for their testimony.

Simpson said last fall that he put his faith in the jury system and was confident of an acquittal.

“If I have any disappointment it's that I wish a jury was here,” Simpson said in November, after a four-day preliminary hearing in which prosecution witnesses were cast as opportunists, pimps, con artists and crooks out to make money off him.

“As always, I rely on the jury system,” he said.

Simpson and Stewart walked into the casino hotel room on Sept. 13, 2007, with the other four men, and robbed the sports collectibles peddlers at gunpoint of items that Simpson said had been stolen from him.

Simpson, 61, claims he didn't ask anyone to bring guns and that he didn't know anyone in the room was armed.

Meanwhile, prosecutors, defense lawyers and Clark County District Court Judge Jackie Glass have used 26-page questionnaires to identify prospective jurors with biases and reduced the jury pool from 500 to fewer than 250.
