Nassar awaits sentencing for his child pornography case on Thursday- a sentence that carries at least 27 years in prison after his plea.
"If Michigan State University, USA Gymnastics and the U.S. Olympic Committee had paid attention to any of the red flags in Larry Nassar's behaviour, I never would have met him, I never would have been "treated" by him and I never would have been abused by him", McKayla Maroney wrote.
Nassar is also set to be sentenced in January in two MI courts after pleading guilty to additional counts of criminal sexual conduct related to allegations he assaulted girls under the guise of medical treatment.
Nassar's attorney, Matt Newburg, said he was "devastated" and remorseful, according to a State Journal video.
"At this point, he truly has nothing to lose", she said.
Aside from the criminal cases, more than 100 women and girls are suing Nassar.
Federal prosecutors are seeking a 60-year sentence.
Police responding to school shooting at Aztec High school
Kyle Lincoln from the San Juan County Sheriff Department told KRQE News 13 that police are still searching the school. Parents are able to pick up their children at 516 and Mesa Verde, after they are checked in and accounted for.
He also said: "I really tried to be a good person. After McKayla spoke with an investigator with USA Gymnastics in July 2015, USA Gymnastics and the USOC kept the knowledge of [Nassar's] status as a child molester secret from Michigan State University after 2015 and even said nothing when he ran for school board in his local school district!"
Several gymnasts who say they were assaulted by Nassar while in his care for the treatment of injuries plan to talk with reporters after the child porn sentencing. "I don't need answers from Larry", Denhollander said when asked about Nassar's statement.
McKayla, who said she was molested by Nassar from her early teens, planned to be present in a federal courtroom last Thursday to deliver her victim-impact statement in open court. "Mr. Nassar was, is and, in my view, will continue to be a danger to children".
"He abused my trust, abused my body and left scars on my psyche that may never heal", McKayla told the court in her letter. When news broke that the USA Gymnastics team doctor had been abusing his patients, it cast a dark cloud over a sport that thousands of Americans enjoy watching.
His public downfall began in September 2016, when the Indianapolis Star named Nassar in a report on USA Gymastics' lackluster response to allegations of assault. When he turned in his work laptop computer, officials said it had been wiped completely clean, including the operating system. After police took the trash back to the department and searched it, they found three other external hard drives in a small plastic bag. In November, he admitted to sexually abusing underage girls, three of which were younger than 13 years of age. MI authorities arrested him last November, and in December, federal authorities added child pornography charges. Toward the end of one clip, the agent testified, Nassar is seen allegedly grabbing a hand of one girl and shoving it into the crotch of another. At 14, she made the National Team and was introduced to Nassar.
He's pleaded guilty to several sexual misconduct charges in Ingham and Eaton counties, but has not been sentenced for those offenses.
