A woman died after she was shot and wounded on her farm in Witklip near Hartbeesfontein on Monday, North West police said.
She was about to leave when three men attacked her, Brigadier Thulani Ngubane said.
"She was shot in the cheek, arm and breast before the men fled with her white Toyota Venture."
A passerby alerted the police. Paramedics rushed the woman, in her 30s, to a hospital. She died on arrival.
Police have launched a search for the killers.
