The truck driver authorities say killed dozens of people by plowing into a crowd in France Thursday night has been identified by officials as 31-year-old Mohamed Lahouaiej Bouhlel, who was unknown to French intelligence services.
Bouhlel, who lived in Nice and worked as a delivery driver, was killed in his 18-ton vehicle during a shootout with police.
Two Americans were among the more than 80 killed in the attack, in which the driver mowed down a large crowd with a truck hauling grenades and other weapons during Bastille Day celebrations in Nice, the U.S. State Department said.
The family member confirms to the Austin Statesman that Sean Copeland and his 11-year-old son Brodie were killed in the attack. They were in Nice on a family vacation.
Alyssa Weaver, Sean’s niece, tweeted, "I am asking for prayers for my family, due to the tragedy in Nice, France 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 #CopelandStrong.”
The death toll climbed overnight from 80 to 84 people -- including 10 children -- while dozens more who were injured received treatment, the Ministry of the Interior said.
French authorities say the ID found with the Nice truck attacker revealed that he was a petty criminal. They say the 31-year-old is of Tunisian descent. There is no current DNA confirmation.
