A father and son from Texas were among the dozens killed in the horrific truck attack in the French city of Nice, according to a family representative.
At least 84 people died when a truck driver mowed down pedestrians celebrating Bastille Day in the seaside city.
The State Department confirmed that two U.S. citizens were killed in the attack, saying it was providing all possible consular assistance.
A family representative told NBC News that the victims were Sean Copeland of Texas and his 11-year-old son Brodie.
The Copelands lived just outside of Austin in Lakeway, Texas.
"We are heartbroken and in shock over the loss of Brodie Copeland, an amazing son and brother who lit up our lives, and Sean Copeland, a wonderful husband and father," the family said in a statement distributed by friend Jess Davis. "They are so loved."
