LAS VEGAS -- The Nevada Supreme Court isn't going to let O.J. Simpson out of prison while he appeals his conviction in a gunpoint hotel room heist.

A three-judge panel issued orders Friday concluding that Simpson and convicted co-defendant Clarence "C.J." Stewart didn't meet the "heavy burden" required to be allowed to post bail.

The justices noted that a jury found Simpson and Stewart guilty of "serious, nonprobationable, violent offenses" with firearms involved.

They also cited a Clark County District Court judge's finding that the men posed flight risks.

Simpson and Stewart were convicted of kidnapping and robbing two sports memorabilia dealers in September 2007 at a Las Vegas casino-hotel.

Simpson is serving nine to 33 years in prison. Stewart is serving 7½ to 27 years.

New papers include an affidavit from one of the two memorabilia dealers robbed in the September 2007 encounter, renewing his allegation that Clark County District Attorney David Roger wouldn't let him drop the charges against Simpson.

"I wanted all of the charges against O.J. Simpson dropped," Alfred Beardsley said in the document.

"After I testified, the Clark County district attorney's office fabricated the idea that the reason I was a reluctant witness was because Mr. Simpson had intimidated, threatened or promised me something of value." Roger declined comment Tuesday.

The two-page affidavit also referred to Beardsley's denial before a judge in Santa Monica, Calif., that he received Simpson's NFL Hall of Fame ring to change his story in the Las Vegas case.

"Mr. Simpson has never promised me anything for me to testify the way I did," Beardsley said.

Simpson, 61, was found guilty in October of robbery and kidnapping in Las Vegas. The case stemmed from a bungled attempt by Simpson to recover the memorabilia from a pair of dealers in a room at the Palace Station Hotlel and Casino.

Simpson's defense attorneys argued that he was only trying to retrieve his own stolen property and he didn't know an accomplice has brought a gun to the hotel room.

Clark County District Attorney David Roger argued that a jury had spoken, and the two men should continue to serve their sentences for kidnapping and armed robbery.

Simpson is currently serving a sentence of 9 to 33 years in a northern Nevada prison.

Simpson was acquitted of murder in the 1994 slayings of his former wife Nicole Brown Simpson and her friend Ronald Goldman. However, a civil jury later found Simpson liable for their deaths.
