FedEx Corp. has been sued by the mother of a student who was killed in a bus-truck crash in northern California earlier this month.

The April 10 crash, which killed 10 people and injured 30 others, occurred on Interstate 5 about 90 miles north of Sacramento, where a FedEx semi-truck crossed over a highway median and hit a bus head-on. The bus was carrying Los Angeles-area high school students to Humboldt State University, where they were scheduled to tour the college.

The lawsuit was filed on Tuesday in Los Angeles Superior Court by Rosa Rivera, mother of 17-year-old Jennifer Bonilla, who was killed in the crash. Rivera alleges that the driver of the FedEx truck was negligent and that the company's trucks have a history of vehicle fires.

Although a witness claimed that the FedEx truck was on fire prior to the collision, a preliminary investigation into the crash did not find evidence of a pre-collision fire.

Rivera is seeking $100 million in damages. This marks the first lawsuit filed in connection with the crash.
