At least two Americans are among the victims in the deadly truck attack in Nice, France. Sean Copeland and his 11-year-old son Brodie from Texas were with their family on vacation when they were killed. It was supposed to be a day of celebration as the country celebrated Bastille Day with fireworks. That's when police say a French-Tunisian man plowed his truck into the crowd killing at least 84 people and injuring 100 more.
