A confession made by one of the five accused in the Stella Londt murder trial, will be admissible as evidence against him in court.
91-year-old Agnes Burns and her 87-year-old friend Rosemary Langton were killed during a robbery at the frail care centre in October 2019.
Their bodies were found bound and gagged in separate bedrooms, which had been ransacked.
Several valuable items, including Kruger Rands, had been stolen.
When the trial was remanded last year, a trial-within-a-trial was held to determine the admissibility of a confession statement made by accused number three, Akhona Mnxeba.
Mnxeba told the court that he had not been warned of his right to remain silent or his right to legal representation.
He further alleged that several conversations between him and the investigating officer, Constable Ridwaan Baatjies, had never taken place.
State Advocate Marius Stander called eight state witnesses to disprove Mnxeba's claims.
On Tuesday, the court ruled Mnxeba made the confession freely and voluntarily and without undue influence.
Mnxeba, a former caregiver at the centre Nomgebisi Slangveld, Mkuseli Damaneti, Luxolo Kruisjan, and Nyasha Manyange, face eight charges, including murder and robbery with aggravated circumstances.
They remain in custody.
The trial continues.
