Trevor (83) and Laura (82) Rees were stabbed and beaten to death in their house, in March.
At the time, police suspected the murder took place on March 18, as the bodies were already starting to decompose on March 20, when they were found.
The couple had been been married for 60 years, and had been living in the area for the past 40 years.
Police spokesperson Luit Nomsa Sekele said that police are still investigating the murder case.
“At the moment, there are no leads or any arrests,” she added.
Sekele said the investigating officer is communicating with the couple’s son, Glyn, who lives in Australia.
The police believed, at the time, that the murderer was known to the couple, “as no trace of a struggle was visible at the murder scene”.
One of the neighbours was also reported to have seen a person in a vehicle leaving the Rees’s residence late that evening.
