Nick Leslie, a U.C. Berkeley student who is studying abroad in France, was last seen in the crowd of people watching fireworks along the Promenade des Anglais, according to friends. He has not been heard from since a French-Tunisian man drove a large truck into the Bastille Day crowd, killing at least 84 people and injuring more than 200. The driver of the truck was shot dead by police.l
Leslie's uncle, Fabio Bottini, has been checking hospitals in Nice to try to find his nephew. Bottini has been in contact with Leslie's mother in California.
Friends of Leslie posted on Facebook that Leslie has not contacted them or his family since the attack.
Leslie graduated from Torrey Pines High School before enrolling at Berkeley. He is one of 85 students from UC Berkeley attending an international study program in Nice, the university reported. Three of them suffered broken bones in the attack, school officials said.
Leslie, a native of Milan, Italy, is a junior majoring in the UC Berkeley College of Natural Resources, according to the university.
San Diego State University, meanwhile, has accounted for 17 of SDSU's 24 study-abroad students and four faculty members who are in France and university officials are trying to contact the rest, spokeswoman Katie White told City News Service.
White said SDSU does not have any programs in Nice.
San Diego's Thomas Jefferson School of Law reported that roughly 50 students, along with some faculty and staff taking part in an annual summer program with the University of Nice School of Law, were all safe following the attack.
Supreme Court Justice Clarence Thomas, an instructor for the program, left Nice on Thursday morning, TJSL spokesman Edgar Hopida said.
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.
French officials have deemed the killings a terror attack, though it was unclear if the perpetrator -- identified as 31-year-old Tunisia native and Nice resident Mohamed Lahouaiej Bouhlel -- was directed by or affiliated with an organized jihadist group.
