The incident happened on River Road in Ellenwood in south DeKalb County.

The victim’s parents witnessed the incident, as they had just dropped their daughter off near the bus stop.

"A car came out and hit her. She went up in the air. I ran out into street to watch her, and the car that hit her stopped... slowed down... and could tell they had hit her and kept going," said the victim’s mother Chanda Shannon.

Doctors said Sales has a bruised brain and several broken bones.

Sales was listed in critical condition at Grady Hospital Tuesday afternoon.

As they watched the incident happen before their eyes, Sales’ parents said they didn’t think about running into traffic to help their daughter.

"She was lying there still and I said to her, your Daddy's here. Kept saying Daddy's right here, and I just seen her fingers moving... few times," said the victim’s father Mario Shannon.

The victim’s parents said it was dark outside and told police the car that hit their daughter was an older model 4-door vehicle.

Anyone with information is asked to call DeKalb County police.
