Gymnast McKayla Maroney plunged into the "emotional abyss" of abuse

The Olympic gymnast McKayla Maroney's mother says that the sexual abuse of the gold medalist in the hands of a team doctor plunged her into an "emotional abyss" so deep that the family feared that she would commit suicide.

Erin Maroney and her daughter stripped their anguish in letters to the federal judge who will sentence Larry Nassar on Thursday for possession of child pornography. The Maroneys are asking the court to give him the maximum punishment.
