ST. CHARLES, Mo. (AP) - A Missouri judge has refused to lower the $25,000 cash bond for the former fiancee of Dallas Mavericks star Dirk Nowitzki.

Judge Nancy Schneider made the decision following a hearing Monday in St. Charles, Mo.

Crista Ann Taylor's attorney had argued that his client has a "higher-risk pregnancy" and needs outside medical care. Matthew Fly also said his client suffered a miscarriage in January. But Schneider says Taylor seemed to be in stable condition.

A Texas grand jury has charged her with theft for not paying a Beaumont dentist for thousands of dollars in dental work. She's also accused of violating probation from a Missouri forgery case.

Taylor was arrested at Nowitzki's Dallas home in May. She told The Dallas Morning News that she's pregnant with Nowitzki's child. Nowitzki has filed for custody if a paternity test proves he's the father of the child.
