Coaches and athletic administrators at Ohio State University knew for two decades that Dr. Richard Strauss was molesting male athletes but failed to sound the alarm or stop him, a long-awaited independent investigation into the scandal revealed Friday.

“Students openly discussed Strauss’ examination methods or complained about his loitering presence in the shower and locker room, including in front of coaches and other Athletics Department staff,” the report states.

“Many of the students felt that Strauss’ behavior was an ‘open secret,’ as it appeared to them that their coaches, trainers and other team physicians were fully aware of Strauss’ activities, and yet few seemed inclined to do anything to stop it.”
