Owens' family recently moved from Shreveport, Louisiana, to metro Atlanta for a better life, WSB-TV reported.
Investigators told the news station the gunfire was aimed at Owens’ mother, who was driving the car.
The woman's injuries are not considered life-threatening. Owens' twin sister was sitting in the back seat and was not injured in the shooting, according to WSB.
Police think road rage may have fueled the gunfire, but Sgt. John Bender told The Atlanta Journal-Constitution the motive is still unknown.
Police said although Reed is behind bars, it is still an ongoing investigation.
