Tom Seeberg has always known the name of the Notre Dame football player accused of attacking his daughter, Lizzy, days before she killed herself in 2010.

So when he heard that NFL prospect Prince Shembo for the first time acknowledged he was that player, Seeberg thought the public might finally better understand the frustrating battle he and his wife waged against a powerful university in trying to learn what happened to their daughter.

"I think the context of revealing his name maybe adds to maybe why we certainly accused Notre Dame of conducting a superficial investigation," Seeberg said Tuesday on WGWG-FM 87.7. "But maybe it adds context to why they might conduct a superficial investigation. 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."

During the radio interview, Seeberg defended his daughter's character, reiterated his disappointment in Notre Dame and said the university and police more aggressively investigated the 2012 case of linebacker Manti Te'o's fictitious girlfriend than that of his dead daughter.

Although Shembo's identity was widely known by those familiar with the Seeberg case, it was not publicized by the media, in part because Shembo never was charged with a crime.

Shembo addressed the matter for the first time Saturday at the NFL scouting combine in Indianapolis. He said he did nothing wrong, had "nothing to hide" and that he stayed silent about the accusations under orders from Notre Dame head coach Brian Kelly.

"I think it certainly opens up a lot of questions for him, maybe for ND," said Tom Seeberg, a commercial insurance broker from Northbrook. "I think those are probably for others to ask; for them to answer. ... We just sought truth in this process. So for us, it was never about him personally. It was about really getting to the truth."

Paul Browne, a spokesman for Notre Dame, declined to specifically address Seeberg's comments. But Browne said, "Anyone who heard Mr. Seeberg today could not help but empathize and only imagine how terrible and excruciating his loss."

Shembo's lawyer, Joe Power, said in a Tribune interview Tuesday that his client had done nothing wrong, adding that Shembo's version of what happened was backed by two witnesses and by cellphone records.

Power said any suggestion that Notre Dame conducted a superficial investigation because it involved a star football player was unfair and inaccurate. "It's not like he was a Heisman Trophy candidate," Power said. "He had not even played in his first game yet."

The Tribune in November 2010 reported that campus authorities did not initially tell county police about Seeberg's report of a sexual attack, nor did campus police refer the case to the county's special victims unit, which was established to handle sex offenses.

Lizzy Seeberg was a freshman at neighboring St. Mary's College when she met Shembo. Seeberg, who battled depression and an anxiety disorder, described her account of what happened Aug. 31, 2010, in a typed statement she gave to campus police.

She said she was alone with Shembo in his room when she began to feel uncomfortable with the conversation. "I started feeling as though I was in danger," she wrote. "I didn't feel safe in his room."

Seeberg then described how she cried and her body froze as the alleged attack ensued. Her allegations did not describe penetration; the campus police log listed the complaint as an alleged sexual battery. She said Shembo licked her breast. The incident ended when the player's cellphone distracted him, Seeberg said.

On Sept. 2 she received a text message from one of Shembo's friends, telling her, "Don't do anything you would regret. Messing with notre dame football is a bad idea."
