I’m sorry if this has been discussed before but I was living under a rock and have not been following the story.

Larry Nassar was the former USA Gymnastics team doctor. He was just sentenced to 40 to 175 years for abusing over 150 gymnasts he was supposedly training for the Olympics.
How did this abuse continue for so long? Did not one girl report it to her parents? Did not one father “visit” with him?
If my daughter had been abused I cannot imagine a meeting with the gentleman ending well.
Were any complaints made public?
What finally brought it to light?
