the university conducted an investigation in 2014 and temporarily suspended nassar. but he was ultimately cleared and able to return to his role, seeing and preying upon young patients. my last treatment was in august, 2016. a week later he was let go by msu. i am possibly the last child he will ever assault. reporter: msu says no school official believed nassar committed abuse until media reports emerged two years later in 2016. they say allegations of a cover-up are simply false. the disturbing truth is, you could have been stopped back in 1997. reporter: the survivor la ris a boyce said when she told the head coach of her abuse in 1997, she was not believed. it sounds eerily familiar to what every single woman was told all the way back to 1997.
