Nice attack: Americans Sean and Brodie Copeland from Texas killed

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."

"This is a very difficult time for our family," Sean Copeland's brother Troy later told NBC News. He declined to comment further.

News of the deaths was also reported by the Austin American Statesman newspaper, which said Brodie played youth baseball and his father was a coach.

The local Hill Country Baseball league posted a tribute on its Facebook page mourning the loss of one of their "very own."

"Nobody deserves this type of fate, especially not such a wonderful family," it said.
