LAS VEGAS -- Two co-defendants pleaded guilty to reduced charges Tuesday in the O.J. Simpson armed robbery case.

Both men agreed to testify against Simpson and three others -- Michael McClinton, Clarence Stewart and Charles Ehrlich -- in the alleged Las Vegas hotel room theft of sports collectibles from two memorabilia dealers.

"Guilty, sir," said Walter Alexander, who pleaded guilty to felony conspiracy to commit robbery.

Charles Cashmore pleaded guilty to felony accessory to robbery during a separate arraignment minutes later before Clark County District Court Hearing Master Kevin Williams.

Clark County District Attorney David Roger agreed to drop charges including kidnapping, armed robbery, assault with a deadly weapon and conspiracy against both men. Both men remain free pending sentencing.

Williams ordered Cashmore released from house arrest. Roger said Cashmore could get probation or up to one to five years in prison at sentencing, which will come after an April 15 status check.

The district attorney said he will seek a suspended sentence for Alexander, which could get him probation instead of one to six years in prison.

Simpson, Stewart, McClinton and Ehrlich are due in court for a preliminary hearing on Nov. 8 and 9.

At that time, Las Vegas Justice of the Peace Joe Bonaventure Jr. will decide whether there is enough evidence to send the case to trial in state court.
