Las Vegas ? O.J. Simpson stood before a judge Wednesday and firmly spoke a phrase he has uttered in other courtrooms in the past: “Not guilty.”

This time the former football star was arraigned, along with two other men, on suspicion of kidnapping and armed robbery of sports memorabilia dealers in a strange case that has ballooned to 12 charges that could send Simpson and the others to prison for life.

Simpson’s notoriety, gained from past trials on charges of murder and road rage, looms in the background of the Las Vegas episode. His attorney said jury selection would be an “onerous” task that would probably last longer than the trial itself.

“I am very concerned that we get 12 people on the jury that can listen to the evidence that occurs in the courtroom,” attorney Yale Galanter said on the courthouse steps. “People are going to have opinions.”

Simpson’s co-defendants, Charles “Charlie” Ehrlich, 53, and Clarence “C.J.” Stewart, 53, also entered not guilty pleas, and Clark County District Judge Jackie Glass set trial for all three men for April 7.
