The news kept getting worse. First, Mourad Laachraoui lost his brother Najim in the Belgian airport attack on March 22. Then he learned his sibling had been one of the ISIS-affiliated bombers who killed dozens and injured hundreds that day. Now Laachraoui, a European taekwondo champion who will represent Belgium in the Rio Olympics, must come to terms with the tragedy. He struggles with conflicting feelings of missing Najim while despising his “unimaginable” actions — and the stigma of sharing one of his nation’s most hated surnames.
