The Lombardy West community, north of Johannesburg, has called for increased police visibility and vigilance.
The community held a candlelight ceremony at the spot where the body of Olorato Mongale was discovered.
The 30-year-olds body was found hours after she left her residential complex with a man known only as John in a VW Polo on Sunday.
Police are still searching for the man.
These young female residents say they no longer feel safe.
