Gold medal monster: Victims recount years of abuse by USA Gymnastics doctor Larry Nassar

For more than two decades, Larry Nassar was regarded as one of the country’s premier sports medicine doctors as he treated numerous Olympic gold medalists and worked his way up the ranks at USA Gymnastics.

But as sentencing continues for Nassar inside a Lansing, Michigan, courtroom, dozens of girls and women are painting a very different portrait of the doctor - that of a serial sexual abuser who molested at least 140 athletes and tragically altered their life trajectories.

"I testified to let the world know that you are a repulsive liar and those 'treatments' were pathetically veiled sexual abuse," victim Kyle Stephens said to Nassar in court on Tuesday.

"Perhaps you have figured it out by now, but little girls don't stay little forever," Stephens added. "They grow into strong women that return to destroy your world."

The 54-year-old Nassar – who is already serving 60 years in federal prison for child pornography crimes – faces between 40 and 125 more years behind bars after pleading guilty in November to molesting seven girls. Over the four-day sentencing, which began Tuesday, nearly 100 of Nassar’s victims are expected to address the court about the abuse they endured at the hands of the disgraced doctor.

Nassar joined the USA Gymnastics national team medical staff in 1986 as an athletic trainer and eventually became the team’s medical coordinator until 2015. He also ran a clinic and gymnastics club at Michigan State University, where he was a faculty member.

While accusations of abuse date back to 1994, it wasn’t until a September 2016 article in The Indianapolis Star reported allegations of abuse by two former gymnasts that actions were taken against Nassar. Following the allegations, Michigan State reassigned Nassar from his clinical and teaching duties before eventually firing him. Nassar claims that he retired from his role with USA Gymnastics, but the organization said it fired him in 2015 and notified law enforcement "after learning of athlete concerns."

Since the initial allegations were made public, more than 140 girls and women – including Olympic gold medalists McKayla Maroney, Aly Raisman, Gabby Douglas and Simone Biles – have accused Nassar of abuse.

“Dr. Nassar was not a doctor, he in fact is, was, and forever shall be, a child molester, and a monster of a human being,” McKayla Maroney wrote in her victim statement. “For me, the scariest night of my life happened when I was 15 years old. I had flown all day and night with the [U.S. gymnastics] team to get to Tokyo. He’d 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.”

Raisman tweeted earlier this week that she would not attend the sentencing "because it is too traumatic for me. My impact letter will be read in court in front of Nassar. I support the brave survivors. We are all in this together."
