A deputy U.S. marshal has died of cancer linked to the 2001 World Trade Center response.

The U.S. Marshals Service said Wednesday that the passing of Zacarias Toro is considered a line-of-duty death. It says the World Trade Center Health Program determined his cancer resulted from his work on at the trade center after 9/11.

The Nanuet (NAN'-yoo-eht), New York resident died Sunday.

Marshals Service Director Stacia A. Hylton (STAY'-shuh HIHL'-tuhn) says the heroism shown by Toro and other responders should never be forgotten.

Toro was the recipient of the Marshals Service Purple Heart Award.

Survivors include his wife Lorraine; children Zachary, Jeremy, Nicholas and Emily; and his mother.
