Olympic gymnast McKayla Maroney made a powerful statement Thursday morning during the sentence hearing of former USA Gymnastics and Michigan State University team doctor Larry Nassar .

Maroney, who alleged in October that Nassar began sexually abusing her when she was 13, was not in court. Michigan state Assistant Attorney General Angela Povilaitis read the gymnasts victim impact statement as a photo of Maroney at the 2012 Summer Olympics hung behind her.

Maroney, 21, wrote about starting gymnastics when she was 18 months old and entering her first competition when she was 7. She said making the U.S. National Team at 14 was remarkable and amazing, but that it came with a price.

I was told to trust [Nassar], that he would treat my injuries and make it possible for me to achieve my Olympic dreams, the statement said. Dr. Nassar told me that I was receiving medically necessary treatment that he had been performing on patients for over 30 years. As it turns out, much to my demise, Dr. Nassar was not a doctor, he in fact is, was, and forever shall be, a child molester, a monster of a human being. End of story.

More than 140 women including Maroneys former teammates Aly Raisman , Gabby Douglas and Simone Biles have accused Nassar of molesting them. Nassar pleaded guilty in November to 10 counts of first-degree sexual misconduct.

He abused my trust. He abused my body and he left scars on my psyche that may never go away, Povilaitis read from Maroneys statement.

For me, the scariest night of my life happened when I was 15 years old, she continued. I had flown all day and night with the team to get to Tokyo. Hed given me a sleeping pill for the flight, and the next thing I know, I was all alone with him in his hotel room getting a treatment. I thought I was going to die that night.

She wrote that Nassar also abused her twice while she was competing in the 2012 Olympics.

Maroney called for several organizations to be held accountable for allowing the abuse to go on for so long.

A simple fact is this: If Michigan State University, USA Gymnastics and the U.S. Olympic Committee had paid attention to any of the red flags in Larry Nassars behavior, I never would have met him, I never would have been treated by him, I never would have been abused by him, she said.
