Jury selection was expected to take a week and the trial against the former football star and television personality could take at least a month, court officials told the Las Vegas Review-Journal.

The one-time Buffalo Bills star allegedly robbed two sports memorabilia dealers at gunpoint. Simpson said he was trying to retrieve his own property.

Simpson, acquitted in the 1995 deaths of his wife and a friend, and Clarence Stewart face a number of charges -- including armed robbery and kidnapping -- in last fall's incident in a Palace Station hotel room, the Review-Journal reported said. If convicted on all charges, they could face up to life in prison.

Four co-defendants pleaded guilty to reduced charges, an agreement offered in exchange for their testimony.

Defense lawyers must ensure a jury panel without jurors who want to convict Simpson because he was acquitted in the in the double slayings, Charles Kelly, a defense lawyer and former prosecutor, told the newspaper

"Most people, by and large, believe he got away with murder," Kelly said. "There's going to be a juror with an agenda who wants to right a wrong."
