Officials say at least 84 people are dead and dozens are injured after the driver of that truck drove up onto the sidewalk Thursday night and plowed through the crowd of Bastille Day revelers, accelerating as the attack stretched for more than a mile.
Back in Texas, the Copeland family is now mourning the loss of Sean Copeland and his 11-year-old son, Brodie, who are among the dead in France.
Family members confirmed to ABC News both Sean and Brodie were on vacation with their family in France when the attack occurred.
Alyssa Weaver, Sean's niece, says the family is asking for prayers.
"I lost my uncle Sean and my 11-year-old cousin Brodie. I ask for prayers for my aunt Kim and my two other cousins, Maegan and Austin, during this tough time and prayers for my family's safe trip back home," Weaver says, in a statement.
Meanwhile, Brodie is being remembered for his talents on the youth baseball field.
The Hill Country Baseball team also called for prayers for the Copeland family after this tragic turn of events.
"This afternoon our very own Brodie Copeland, as well as his father Sean Copeland, were killed during the terrorist attack in Nice, France," the statement reads. "Nobody deserves this type of fate, especially not such a wonderful family.
"You are in our hearts, thoughts, and prayers. Rest in peace, Brodie and Sean, you will be remembered by many."
A GoFundMe page has been set up to support the family. It has already raised more than $15,000.
