Seven people were killed and five injured following a shooting in Kagiso, the West Rand, on Saturday.
Police spokesperson Brigadier Brenda Muridili said a gunman entered a house in the area and shot the owner, his girlfriend and a neighbour.
"On the suspect's way out, he is alleged to have continued to shoot randomly," Muridili added.
"The street was busy as there was a wedding celebration nearby. Two more people were certified dead on the scene and two were rushed to hospital [for treatment for their] gunshot wounds."
On Sunday, Muridili confirmed two more people died while in the hospital.
"Five were taken to hospital and one of them has since been discharged."
She said a case of murder and attempted murder would be opened.
