Duvall said the two teens had been target shooting earlier in the day and that the older boy had the gun in the truck when they came to the park.
“Apparently (it) belonged to his father. He had taken it from home earlier that day,” Duvall said.
The 16-year-old was put into a medically induced coma after he lost his left eye and was bleeding from his brain due to the bullet exiting the back of his head, police said. There has been no update on his condition.
Chestney was released from the Paulding County Adult Detention Facility on a $7,900 bond and has been charged with false report of a crime, pointing a gun at another and reckless conduct, according to jail records.
Police said any further charges against Chestney will be based on whether or not the teen survives.
