SAN JOSE -- The murder case of a Monte Sereno millionaire has been postponed until Wednesday, when the lawyer for the alleged prostitute accused of being an accessory to murder will ask that her case be separated from the three men accused of doing the killing.

All four defendants were supposed to be in Santa Clara County Superior Court together Monday, but only Raven Dixon, 22, appeared. The three men will join her at the 9 a.m. plea hearing Wednesday.

"If they're saying it will save the county a couple of bucks to try them all together, that's not going to work," said Dixon's lawyer, John Ambrosio. "If she's sitting in trial next to three accused murderers, this is something called undue prejudice. Just by associating with them, she'll look guilty."

Dixon is accused of giving three men with criminal records -- Javier Garcia, Lukis Anderson and Deangelo Austin -- information to break into the multimillion-dollar Monte Sereno estate of Ravi Kumra on Nov. 30.

Kumra -- who made his millions in telecommunications and once owned the concert venue The Mountain Winery -- was robbed of a coin collection, cash and jewelry and then killed. His wife, Harinder Kumra, was beaten.

Dixon, who was arrested weeks later for prostitution then charged as an accessory, had known Kumra for years. In court papers filed in Kumra's 2010 divorce case, Kumra was accused by former business associates of living "in a fantasy world of prostitutes and illegitimate children."

But Dixon's family says she is a "good girl" and didn't know any of the three men accused of killing Kumra. Her mother, Sandra Mitchell, of Alameda, wouldn't specify her daughter's relationship with the 66-year-old millionaire whom Dixon had met when she was no older than 17. Her lawyer said she did some filing work for Kumra. Mitchell acknowledged at a recent court hearing that her daughter had been at the mansion six months ago when Kumra had invited "Brazilian escorts" to a party there.

"She loved and respected his family," Mitchell said. "She wouldn't have done anything to harm him."
