A disgraced sports doctor, Larry Nassar, drugged, abused and impregnated a Michigan State University field hockey player in 1992 – and the university's athletic director took steps to hide it, according to a new explosive trial.

The lawsuit, filed by Erika Davis in federal court in Grand Rapids, alleges that Davis told her coach, Martha Ludwig, that the sexual assault was videotaped, prompting Ludwig to confront Nassar about the allegations and to ask a copy of the images. in pursuit, which was obtained by the Lansing State Journal.

George Pearls – a current university administrator who stepped down from his position as Michigan's state athletic director in 1992 – stepped in, and Davis's complaint was dropped. Pearls then forced Ludwig to hand over the video before resigning and signing a non-disclosure agreement, according to the lawsuit.

The lawsuit, which names Nassar, Michigan State, its board of directors and USA Gymnastics as defendants, also claims that Davis was impregnated with the sexual assault and that Nassar, 55, is the only person who could have been the Father. Davis later miscarried, according to the lawsuit, claiming that the MSU Police Department directed Davis in another direction when she reported the incident with two friends in October 1992.

"The police told them that as she was an athlete, she had to report it to the sports department," the lawsuit says. "The detective explicitly told them that he was powerless to investigate everything that's going on [in] the athletics department and go to the athletics department. Complainant Erika explained that the sport department had already fired her and that the sergeant replied that George Perles was a "powerful man" and that she should simply drop him off.

Davis then lost his field hockey purse, according to the lawsuit, which accused Michigan officials of making "big efforts" to conceal Nassar's behavior.

"The defendant Michigan State University could have stopped the accused Nassar's conduct in 1992, but she did not do it," the lawsuit says.

Perles and Davis' lawyers did not immediately return messages seeking comment, reports the Lansing State Journal.
