Cheyenne Grace, shown from Facebook, was killed Friday night in a four-wheeler wreck involving a Richmond County deputy.

The mother of 17-year-old Cheyenne Grace, is calling for justice in response to her daughter’s death in a four-wheeler accident on Friday night in Augusta.

In a dark Facebook video posted Saturday morning, DeShandra Patrice Parks called out the Richmond County Sheriff’s Office and disputes their account of the accident. The wreck is under investigation by the Georgia State Patrol.

“The Richmond County Sheriff’s Office ran over my f***ing baby and killed her,” DeShandra says. “We are going to get justice for my f***ing baby.”

Witness video shows the teen’s body covered by a sheet in the road.

According to the sheriff’s office, the teen was riding the four wheeler on Barton Chapel Road when it was struck by a Dodge Challenger turning onto Barton Chapel Rd from Blossom Drive.

“The four wheeler then traveled into the oncoming path of a deputy driving his patrol car on Barton Chapel Road,” sheriff’s Sgt. Caleb Lee said.

The Jail Report asked Sgt. Lee about reports that the four-wheeler was hit during a chase. His answer: “Investigation is turned over to GSP.”
