Authorities say Dejon R. Wideman was arrested Monday. Police say he swerved into oncoming traffic early Sunday morning and hit a car traveling in the opposite direction.
Police say 16-year-old Johlonda Lindsey died after she was thrown from the car.
Gwinnett County schools spokeswoman Sloan Roach said Monday was “a very difficult day for everybody” and that a steady flow of students at Meadowcreek High School had spoken with counselors.
It was not immediately clear whether Wideman has an attorney.
