A Phoenix judge ruled Thursday that former NFL star Darren Sharper is not entitled to bail in Arizona, finding "proof evident and presumption great" that he raped a woman in Tempe on Nov. 21.

In making his ruling, Maricopa County Superior Court Judge Warren Granville cited DNA evidence from inside the woman's vagina that partially matched Sharper's. Sharper did not previously know the woman, identified in court as "Victim B,"according to testimony from Tempe police Det. Kevin Mace. Another woman in the apartment that night, identified as "Victim C," said she witnessed Sharper naked and making thrusting movements over Victim B, who has no recollection of what happened in the hours after consuming a drink Sharper made her that night, Mace said.

The judge said Sharper should be entitled to $1,000 bond on the other four charges he faces in Arizona, including the drugging and rape of another woman, identified as "Victim A," and the drugging of Victim C.

But Granville's ruling regarding Victim B is likely to be enough to keep Sharper incarcerated indefinitely in Los Angeles, where he is charged with two more rapes.

At issue in Granville's court was whether Sharper was entitled to post bond in the Tempe case and potentially be released from jail. Because his charges in Arizona were deemed non-bondable, Los Angeles Judge Renee Korn previously said she would not release Sharper, who has been locked up since Feb. 27.

If Granville had ruled Sharper was entitled to bond on all charges, Korn might have released him as soon as Friday. Korn will consider the issue again in a hearing scheduled for Friday morning in Los Angeles.

To keep him in jail on sexual assault charges without bail, Arizona prosecutors needed to show "proof evident and presumption great" that Sharper was guilty, according the state constitution. Granville said the burden was met with Victim B.

An expert witness on genetics and testing, Dr. Ruth Ballard, testified for the defense and noted that the reports showed that none of Sharper's sperm was found on any individual. She said the type of DNA found could have come from skin, saliva or other sources.

To rebut the point about the lack of sperm found on the alleged victims, prosecutor Yigael Cohen elicited testimony from Mace that said Sharper had a vasectomy. After Sharper's attorney, Skip Donau, objected, Mace said he learned of the vasectomy from Los Angeles police and Victim A, who had a prior consensual sex relationship with Sharper.
