His accomplice got away and was still on the run, said police spokesperson Captain Coba Brits.
The shooting was on Sunday night around 21:00.
Brits said two men confronted a young woman, the owner’s daughter, when she went to see why the family’s dogs were barking.
“The family was having dinner outside when the young woman went to check on the dogs. When she got to the door she was confronted by two men,” she said. “The men with firearms forced her and the family inside the house and ordered them to lie on the floor.”
