Nancy Erika Smith, the lawyer for the woman who accused Mr. Maggette and Mr. Fairfax, Meredith Watson, said in a statement Friday that Ms. Watson had been raped by a Duke basketball player during her sophomore year but did not name the player. Ms. Smith also said that Ms. Watson had reported her rape to an unspecified dean at the university, but that the dean had “discouraged her from pursuing the claim further.”

Duke has acknowledged it is investigating an allegation that a player raped the woman, but a spokesman for the university declined to comment on the identity of the player or the assertion that the university failed to act on the accusation.

“We are in the process of gathering information to determine what policies and procedures were in place during the time period in which these events are alleged to have occurred, and whether they were activated and followed,” said Michael Schoenfeld, a spokesman for Duke. “We are not able to provide further information or comment on any individual at this time.”

Years before Ms. Watson came forward as the second woman to publicly accuse Mr. Fairfax of sexual assault, inflaming a political crisis in Virginia, she told multiple friends that she had been raped by Mr. Maggette, according to one of those friends and Facebook messages exchanged with another.

R. Stanton Jones, a partner at the law firm Arnold & Porter in Washington who grew up with Ms. Watson in Baltimore, said she told him that she had been raped by Mr. Maggette. She told Mr. Jones about it while he and Ms. Watson were both home for the summer in 2001, he said.
