“We offer a prayer for the eternal rest of her soul and express our sincere condolences to her family,” INDES said in a statement.
“Katherine embodied the joy and energy that makes surfing so special and dear to all of us, as a global sports ambassador,” said ISA about the surfer, whose brother, Jose Diaz, is the president of the Salvadoran Surfing Federation (FESASURF).
“He excelled in international competition, proudly representing his country at both the ISA World Surfing Games and the ISA World Junior Surfing Championship.
“We extend our heartfelt condolences to Katherine’s family, to the surfers of El Salvador and to all those in the international surfing community whose lives have touched her.”
FESASURF, ISA and the National Sports Institute of El Salvador did not respond to CNN’s request for comment.
