Shortly after a 6-year-old boy was injured in a hit-and-run near Kennesaw Mountain National Battlefield Park, a man who described himself as a passenger in the vehicle appeared to cooperate with police.

He and two other passengers even gave investigators the so-called driver’s nickname. They said they knew him as “Moonie.”

On Monday, Cobb police said Brian Demarco Locklin wasn’t a passenger in the blue 2008 Chevrolet Impala that hit Jack Ford on Feb. 18. Locklin, police said, was the driver.

Locklin, 20, was initially arrested on the scene on an unrelated probation violation out of Fayette County, Cobb police spokesman Wayne Delk said.

At some point during their investigation, authorities said they learned Locklin made false statements to police.

Jack is recovering from the accident, which occurred as he was crossing Burnt Hickory Road at Old Mountain Road with family.

Jason Ford, Jack’s father, told Channel 2 Action News that the boy recently lost his mother to cancer, Channel 2 reported.

“God, and his mother, definitely had a protective bubble around him,” Jason Ford posted on Facebook.

Locklin has been charged with serious injury by vehicle, felony hit-and-run and making false statements.
