The son of a Michigan State University trustee is pushing back against a lawsuit that claims his father covered up a rape in 1992 by disgraced sports doctor Larry Nassar, dismissing the onetime field hockey player’s account as a “fabrication” in search of a hefty payout.

The lawsuit — filed Monday in federal court by Erika Davis — alleges Davis was drugged, raped and impregnated by Nassar, who was a student at the university’s College of Osteopathic Medicine at the time. Davis then told her coach, Martha Ludwig, about the sexual assault and that the rape had been videotaped, prompting Ludwig to confront Nassar and demand a copy of the footage, according to her lawsuit, which claims George Perles, MSU’s then-athletic director, went to “great lengths to conceal” Nassar’s actions.

But Perles’ son, Pat, told ESPN his 84-year-old father has no recollection of receiving Davis’ complaint and questioned the chronology put forth in the explosive lawsuit, which claims George Perles then forced Ludwig to hand over the video before resigning and signing a non-disclosure agreement.

“His memory is remarkably good for a man his age,” Pat Perles said. “He doesn’t remember any of this because it never happened. There was no meeting with the field hockey coach. It certainly didn’t include this subject. It’s a fabrication.”

Perles, who also coached MSU’s football team from 1983 through 1994, announced his plans to step down as athletic director in April 1992, ESPN reports. His replacement took over the following month, according to media reports, but Perles remained a part of the program as the Spartans football coach for two more seasons.

“The timeline doesn’t fit,” Pat Perles told ESPN. “They could amend the lawsuit, but the claim is that the field hockey coach met with my father in mid-to-late May.”

Ludwig could not be reached for comment, and an attorney representing Davis declined to answer questions when reached by ESPN.

A spokeswoman for the university told the Lansing State Journal on Tuesday that Michigan State officials are “deeply sorry” for the abuses committed by Nassar, as well as the trauma experienced by all sexual assault survivors.

“While the protocols and procedures mentioned in this lawsuit do not reflect how sexual assault claims are handled at MSU, we are taking the allegations very seriously and [are] looking into the situation,” Michigan State spokeswoman Emily Guerrant told the newspaper.

The lawsuit alleges Davis was impregnated during the sexual assault and that Nassar was the only person who could have been the father. She later had a miscarriage, according to the lawsuit, which also claims MSU’s police department pointed Davis in another direction when she reported the incident with two friends in October 1992.

“The police told them that since she was an athlete, she had to report it to the athletic department,” the lawsuit claims. “The detective explicitly told them that he was powerless to investigate anything that takes place [in] the athletic department and to go to the athletic department. Plaintiff Erika explained that the athletic department already dismissed it and the sergeant responded that George Perles is a ‘powerful man,’ and she should just drop it.”

The university’s current police chief, Jim Dunlap, dismissed that allegation as “nonsense,” claiming the department would not have declined to probe Davis’ claims due to any effort by Perles.

“I wasn’t the chief 26 years ago, but I was here 26 years ago and I can tell you philosophically that just didn’t occur, that we refuse to take a report,” Dunlap told ESPN. “You might not like an outcome from an investigation, but I can say unequivocally we don’t give investigations to non-law enforcement agencies.”

Pat Perles, meanwhile, declined to comment on whether law enforcement agencies contacted his father this week. While saying he believes Michigan State should look into Davis’ allegations, he took a parting shot at her credibility.

“[My parents’] feeling more than anything is that this detracts from the true suffering and pain that all these women have gone through and continue to go through,” Perles told ESPN. “It discredits the pain and suffering of all these other people who were abused by Nassar because someone is trying to take advantage for a quick payday.”

Nassar pleaded guilty last year to federal child pornography charges and state sexual abuse charges in Michigan and was sentenced to 60 years in federal prison in January. A month later, he was sentenced to 40 to 125 years for the sex abuse charges.
