Former Michigan State University and USA Gymnastics national team doctor Larry Nassar will spend the rest of his life in prison after hundreds of people – mostly young women – came forward to report sexual abuse by Nassar under the guise of “treatment.”

TELL DR. PHIL YOUR STORY: Life in crisis?

At 15, Emma Ann, who was the youngest of Nassar’s accusers to make a victim impact statement at his sentencing hearing in January 2018, had known Nassar her entire life and had been under his care since age 8. She says her mother, Leslie, “Couldn’t have done anything,” because “She didn’t know anything.”

Leslie says Nassar was a close, personal friend who was “like family” to them, but looking back, now believes Nassar used that relationship to groom Emma Ann.

“I feel like I really missed it,” she says.

Leslie says she feels tremendous guilt over not recognizing the signs that her daughter was being abused, but, aside from Nassar, who does she say she holds responsible for allowing the abuse to continue as long as it did?

Emma Ann’s story is featured in the new book, The Girls: An All-American Town, a Predatory Doctor, and the Untold Story of the Gymnasts Who Brought Him Down, by author Abigail Pesta. Available now, wherever books are sold.

In a Dr. Phil exclusive airing Thursday, Emma Ann, her mother, Leslie, and others come together to speak with Dr. Phil about the case.
