Figure skaters took to the ice in Washington, D.C., Sunday to honor the victims of the deadly midair collision that claimed the lives of 67 people, including many in the close-knit skating community.

At the end of his figure skating performance, when the last note of his parents’ favorite song played in an arena packed with spectators and heavy with sorrow, Maxim Naumov dropped to his knees at the center of the ice. He remained there for what seemed like forever, awash in a spotlight, looking lost and sobbing.

Organizers of a figure skating benefit event in Washington, D.C. said they have already raised $1.2 million for victims of the plane crash over the Potomac River and first responders.
