OLYMPIC swimmer Ariana Kukors Smith sued USA Swimming on Monday, alleging the sport’s national governing body knew her former coach sexually abused her as a minor and covered it up.

Kukors Smith alleges Sean Hutchison, who began coaching her at a swim club near Seattle, groomed her for sexual abuse when she was 13, started touching and kissing her when she was 16, and engaged in sexual activity with her when she was 17.

“This lawsuit is about holding people accountable who should have protected a 15-year-old girl,” Kukors Smith told reporters, adding, “I needed help and there were people in positions of power that could have helped me.”

Hutchison has denied the allegations, which emerged earlier this year when Kukors Smith, now 28, posted an emotional essay online. The assistant coach on the 2008 U.S. Olympic team has not been charged with a crime.

The case marked another scandal for USA Swimming and for the sports world, which has faced accusations that coaches and others, including former USA Gymnastics sports doctor Larry Nassar, exploited their positions to sexually abuse athletes in their care.

Kukors Smith, the 2009 world champion in the 200-meter individual medley who placed fifth in that event at the 2012 Games, also sued longtime Olympic coach Mark Schubert, saying he failed to report “a reasonable suspicion of child abuse or endangerment.”

USA Swimming and Hutchison’s attorney didn’t immediately respond to emails seeking comment on the lawsuit, which was filed in Superior Court in Orange County, California. A number for Schubert couldn’t immediately be found.

The U.S. governing body of swimming said it first learned of the underage abuse allegations when Kukors Smith posted her essay in February.

The organization had hired a private investigator in 2010 to look into rumors of a relationship between Kukors, then 21, and Hutchison, then 39. USA Swimming said it closed the investigation without finding any misconduct after the two and others denied the relationship.
