Police say the deceased threatened to shoot the Van Deventers after their daughter tried to take pictures of him smashing the Volvo's windows.
Willeon was shot in his leg, his wife Annabell in her ankle and their daughter in her arm and leg.
The three victims were treated for their injuries in the Mossel Bay Provincial Hospital and discharged on Monday morning.
