A state prosecutor in Kentucky said yesterday a complaint filed by a woman in an alleged extortion attempt of Louisville coach Rick Pitino won't be prosecuted because it lacks supporting evidence.

Jefferson County Commonwealth's Attorney David Stengel said he was taking no action on the complaint Karen Cunagin Sypher filed to the police department's sex-offense unit last week. The report has not been released publicly.

Sypher has pleaded not guilty to federal charges of trying to extort money from Pitino and lying to the FBI. She is accused of demanding college tuition for her children, her house to be paid off and, eventually, $10 million.
