AUSTIN, Texas (AP) — Relatives say a father and son from the Austin area are among the victims of the deadly truck attack in Nice.

Family friend Jess Davis says 51-year-old Sean Copeland and his 11-year-old son Brodie were killed Thursday evening in what French authorities have described as a terror attack.

Davis released a statement Friday on behalf of the Copeland family, saying they are "heartbroken and in shock."

State Department spokesman John Kirby said earlier that two Americans were killed, but didn't identify them citing privacy.

Davis says the Copelands, from Lakeway, were on a European vacation that began in Spain. They were celebrating Bastille Day in Nice.

The statement says Sean Copeland is "a wonderful husband and father" and Brodie is "an amazing son and brother who lit up our lives."
