The latest bodies were found over the weekend, according to local police, adding to a grim tally that has mounted over the past two months. Officers have made arrests in three of the cases, but those are not believed to be connected to the others.
Among the identified victims is Busisiwe Mahlangu, 37, whose body was discovered in Kempton Park on 15 July. She was found naked with her hands bound by cable ties. A suspect believed to be her partner was arrested two days later and remains in custody; he has not been linked to any of the subsequent deaths.
Another victim, Itumeleng Kekana, was also found in the same area. The BBC reported that she was seen in a photograph wearing a soccer supporter's jersey, but no further details about her case have been released.
The killings have heightened fears among women in Ekurhuleni and across South Africa, a country already grappling with persistently high levels of gender-based violence. Police have not publicly identified the remaining victims or provided a timeline for all 12 discoveries.
