The girl was in a black Honda sedan, driving south in the 2800-block of Ashland Avenue about 12:05 a.m., when she lost control of the vehicle, according to CPD. That caused the car to jump the curb and hit a tree before coming to a complete stop.
The impact was so violent the car was broken up into pieces.
