A USC student was one of the three people killed in a fiery crash involving a Tesla Cybertruck in the Bay Area this week, the university confirmed.

Four college students were inside the Tesla Cybertruck that crashed and erupted in flames in Piedmont early Wednesday morning, all of whom knew each other from high school and athletics, a family member of one of the passengers said.
