Shembo denies any wrongdoing, the Chicago Tribune reported. He told the NFL scouting combine in Indianapolis Saturday he has "nothing to hide."
Tom Seeberg -- whose daughter, Lizzy, was a freshman at St. Mary's College in Notre Dame, Ind., when she said Shembo attacked her -- accuses Notre Dame of shielding a star football player.
Lizzy Seeberg died from an overdose of prescription drugs a few days after she reported the alleged assault.
"I think the context of revealing his name maybe adds to maybe why we certainly accused Notre Dame of conducting a superficial investigation," said Seeberg, an insurance agen who, lives in the Chicago suburb of Northbrook, Ill.
"But maybe it adds context to why they might conduct a superficial investigation," he said Tuesday in an interview with WGWG-FM, Chiago. "In a he-said-she-said matter, you can quickly gather forensic evidence to try to determine what happened there, or you can let it linger like they did. Let evidence spoil."
Joe Power, Shembo's lawyer, told the Tribune that is untrue. He said that when the allegations were first made Shembo had yet to play a football game for Notre Dame.
"It's not like he was a Heisman Trophy candidate," Power said.
Shembo, a senior at Notre Dame, was considered one of the best linebacker prospects in the country as a high school star. He started all 13 games in his final season at Notre Dame and made 46 tackles.
