Two men dressed in black entered the couple’s home on Friday and demanded cash, said Captain Stephen Thakeng.
“Mr Jack Smith, 73, was hit with an unknown object on his head and face until he died in his house. Mrs Aletta Johanna Smith, 72, was also hit with an unknown object and she sustained injuries on her head,” said Thakeng.
The men stole a safe with an undisclosed amount of cash and fled on foot.
No arrests had been made.
