There is nothing in the article about the car having a shooter and a driver. Car was registered to Charles Vallow (who was already dead by Oct 2nd). Brandon saw a gun with a silencer poking out of the car's window. It doesn't say if he saw or didn't see who was holding the gun.
"Brandon was about to pull into his driveway when he saw a gun with a silencer poke out of the Jeep's window, he said. He heard a gunshot as his driver's side window shattered."
