Outsourcing this to the Guardian, since I could not have said it better myself:
Te'o was a sophomore on August 31, 2010, when Lizzy Seeberg, a freshman at St Mary's College, a university across the street from Notre Dame, reported that she was sexually assaulted by a Notre Dame football player. In the stressful aftermath of the assault, which included coercion from the player's friend – "Don't do anything you would regret," the friend texted Seeberg – Seeberg took an overdosed of depression and anxiety medication and died eight days later.
The most comprehensive coverage on sex assault cases at Notre Dame has come from Melinda Henneberger, who covered the school's response to Seeberg's case for the National Catholic Reporter and then provided further commentary for the Washington Post. In the course of her reporting, she was denied access to Notre Dame officials, and found out that Seeberg's family was, too.
