OCALA, Fla. -- The tractor-trailer driver who rear-ended a Marion County school bus near Citra in September, killing an eighth-grader, was arrested Tuesday morning, according to the Florida Highway Patrol.

Reinaldo Gonzalez, 30, was charged with vehicular homicide and reckless driving with serious bodily injury in the Sept. 23 crash.

Frances Margay Schee, a 13-year-old North Marion Middle School student, was killed in the crash. The bus had stopped on U.S. Highway 301 to let students off when it was struck.

Gonzalez was on his cell phone prior to the crash, troopers said. Investigators also believe Gonzalez violated federal regulations by driving too many hours.

Several other children, the bus driver and Gonzalez were injured in the crash.

Gonzalez's attorney, Larry Turner, said his client understands "the gravity of the situation and he does feel bad about the loss of life and the injuries."
