Hahn was forced to resign in 2004 when a women's basketball player claimed he discouraged her from reporting a rape she said occurred in April 2003 that allegedly involved one of Hahn's players. Hahn claimed that the woman didn't want to report the incident at the time. However, La Salle school policy required Hahn to report the incident to a counselor. This was to ensure compliance with the Clery Act, a federal law which requires colleges to make timely reports of crime on campus. La Salle women's basketball head coach John Miller was also forced to resign on the same day as Hahn, also for not reporting the alleged rape.

The year after he left, 2002, the Terps won the national championship with most of Hahn's recruits. He was given a championship ring by Williams and the Terrapins basketball squad, even though he was not associated with the school anymore.
