Three other students from the program were injured in the attack, with one suffering a broken foot and two suffering broken legs.
Leslie, a junior in the College of Natural Resources, was one of 85 UC Berkeley students attending a study overseas program nearby.
Nicolas Leslie, 20, is known to have been at the Bastille Day celebration and is still unaccounted for, a UC Berkeley spokesman said. Two weeks ago, 18-year-old sophomore Tarishi Jain died when militants attacked a cafe in Dhaka, killing 20.
More than 80 people were killed and more than 200 were injured, about a fourth of them critically, before police killed the driver.
The university said the Federal Bureau of Investigation informed school officials that the body of 20-year-old Nicolas Leslie, from Del Mar in the San Diego area, had been identified. They were among 85 from the school attending a 15-day study overseas program.
"We think he escaped the truck, but he could have been trampled", he said.
The agency confirmed that student Nicolas Leslie, who had been missing since the attack, was among the victims of the attack.
"We're all hoping and holding out that he will be found very soon", Holmes said.
Meanwhile, Sanders said, "The (study abroad) program has been suspended temporarily to commemorate a national three days of mourning in France, and will continue through its planned end date on July 24". In addition, another student, Nick Leslie, is missing. So far, three students have chosen to come back to the U.S.
"This is tragic, devastating news", said UC Berkeley Chancellor Nicholas Dirks.
The University of San Diego reported it has no students in the affected area, and Cal State San Marcos has no students in France this summer. Authorities had been searching for him since Thursday's attack. Other students and the program's director are also looking for him, she said.
Other friends say Leslie was active on social media before the attack, but has not posted anything since the chaos.
